There is no energy in the wind at those wind speeds, nothing to harvest for the turbine. While it may make you feel good to see your expensive yard toy spin, it is not doing anything meaningful in a breeze like that: To give you some idea, a wind turbine with a diameter of 6 meters (pretty large as small wind turbines go) can realistically produce just 120 Watt at 3.5 m/s wind speed. That same turbine would be rated at 6 kW (or more, see the next section), so energy production at cut-in really is just a drop in the bucket. What is more, due to the way grid-tie inverters work, you are about as likely to be loosing energy around cut-in wind speed to keep the inverter powered, as you are in making any energy, resulting in a net-loss of electricity production.
There is nothing wrong with NiFi batteries, and they don't need improvement. Sure you have to add water, big deal, at least you only have to buy them once. Unlike the FLA or AGM batteries you keep talking about which you will be replacing every 5 to 10 years, you only need buy NiFi once. Since you can drain over 80 percent from an Edison style battery and it don't hurt the battery, you don't need as big of a battery bank as with the others, which saves money even up front.
If people really wanted to help the planet they would divorce themselves from the local power company by installing their own one. Get rid of all those power poles, etc. People don't though, most of them can only think short term about saving a few bucks. If the grid ever goes down and stays down, they will wish they chose to do a full off grid, and they will have no power panels are not, because they are not set up for it. They have no batteries or anything to store the power, and those gen sets will soon be out of fuel.
Another good solar kit is the 100W WindyNation. It features one of the best controllers of the products that we reviewed, with an LCD display that shows statistical data such as voltage and the solar state based on the panel output of this kit. Whether you are installing it on your roof, your motorhome or even an outhouse or barn, you will find that this unit produces good results with its high-quality panel.
I can also double or triple the number of panels on this particular system (once I decide on a good place to put them) without changing the inverter or any of the grid-tie connections, which will greatly improve my annual return on investment. It’s just a LEGO-like plug and play to connect more panels to an existing rack of them, plus the inverter has a second set of inputs if you are running in some wires from a string of panels you have placed somewhere else.
A solar installation is a mini-power plant on your roof. It requires knowledge about how to work with DC electricity, wiring, inverters and battery banks. Home solar installations are optimal on rooftops, so there's the danger inherent in working at heights. In many cases, DIY projects are not permitted to be tied into the grid by the local utility, which means if your system is not producing enough electricity, there's no back-up. Many states do not allow DIY electrical systems to begin with. While there may be an initial cost-savings, the disadvantages of DIY solar installations include many factors.

Ensure the whole set-up matches. If you choose a 12V wind turbine then make sure you also choose a 12V inverter and controller to match it. Likewise, if you choose a 24V or 48V system make sure they are all the same voltage. The dump load must be exactly the same as the power rating of the turbine too. If you have 400W rated turbine, then the dump load must match it.
Batteries – an off-grid system will need a bank of batteries to store the electricity. The turbine will produce electricity whenever it spins above the cut-in speed. So you can stockpile this energy in the batteries for when it is needed. Lead acid batteries (deep-cycle) are the most common kinds to use. They can be wired in series or parallel to make a battery bank.
Flexible thin film cells and modules are created on the same production line by depositing the photoactive layer and other necessary layers on a flexible substrate. If the substrate is an insulator (e.g. polyester or polyimide film) then monolithic integration can be used. If it is a conductor then another technique for electrical connection must be used. The cells are assembled into modules by laminating them to a transparent colourless fluoropolymer on the front side (typically ETFE or FEP) and a polymer suitable for bonding to the final substrate on the other side.
72-cell panels are commonly used for larger systems, especially utility-scale but also residential and commercial projects. Most 72-cell panels measure 77x40” with power output in the range of 325-400 watts. 72-cell panels are ideal for larger systems because the bigger size reduces the total number of connections and components, making for an easier installation with less maintenance.

Well, it is a one-piece turbine that starts to produce energy in 8mph winds. Its very efficient 15-in long propeller ensures you natural power in your home, RV, remote cabin, boats, or camp tent. You can quickly mount it anywhere. It also works along with a solar panel, giving you a chance to add a small wind generator to your existing off-grid power system.


What is a small wind turbine? Anything under, say, 10 meters rotor diameter (30 feet) is well within the “small wind” category. That works out to wind turbines with a rated power up to around 20 kW (at 11 m/s, or 25 mph). For larger wind turbines the manufacturers are usually a little more honest, and more money is available to do a good site analysis. The information in this article is generic: The same applies to all the other brands and models, be they of the HAWT (Horizontal Axis Wind Turbine) or VAWT (Vertical Axis Wind Turbine) persuasion.
My electric company has a “green rate” where they sell you 100% solar energy for a premium. The interesting thing is you also get a discount that removes most of the premium. For myself it’s made a very small difference in my electric bill and I get to feel good knowing I’m using solar energy without owning it. They don’t actually advertise this plan at all so you might have to slueth through their website to find it.
We installed solar on our 45-degree metal roof last year. We previously had problems with ice sheets that would shoot off and put bystanders in danger. The panels do not melt the snow, but seem to be advantageously working as snow and ice-guards. Interestingly we have noticed that the light passes right through the snow and we still get power. On a bright day it still seems to run just about full generation.
In a different reply above, I mentioned that retail-wholesale rates are much more equitable. You get paid the wholesale rate for the kWh you put into the grid, similar to what the industrial solar farm gets paid. The utility immediately resells that kWh at the normal rate, which has the transmission, maintenance, and admin costs built in. When you need a kWh in the evening or on a cloudy day, you pay the normal (retail) rate as well, thus you pay for the electricity and transmission, maintenance, and admin costs as well. Typically, the wholesale rate is 1/2 to 1/3 of the retail rate, so you have to produce 2 to 3 times as much as you consume from the grid to zero your bill (including any fixed monthly fees).
Since wife is into historic preservation buy older homes to fix up and remodel for extra cash every few years so we have always been limited by the home as it was originally designed. Well we are finally considering doing one for ourselves and with the kids finishing high school it can be much smaller. Reading your blog has given inspiration for many aspects of our lives, working less, living more and enjoying simple things. Thank you!
Right now, the best way to install solar is through a qualified professional who holds a certification to do so and works with high-quality solar panels. The industry-standard certification is awarded through the North American Board of Certified Energy Practitioners (NABCEP). In the future, though, you will likely be able to install solar yourself. SETO awardee Fraunhofer CSE is developing a plug-and-play solar array that enables consumers to easily attach the panels to their roofs using an adhesive roof mounting system and connect it to the grid in under 12 hours. This is still in development – until it is available at your local home improvement store, you should work with a certified solar installer.
Depending on the size and type of residential solar system to decide to purchase, the location of installation can vary. In most cases, homeowners choose to install solar panels on the roof of their home. It’s a great space saver, if you don’t have a lot of land, and can receive great contact with the sun’s rays. But, what if you the majority of your roof is under shade from large trees? Maybe it’s better to mount your solar panels in the yard instead. This is also a good option when you need a larger amount of solar panels, that your roof might not be able to accommodate.
Usually, the solar power systems uses 12 volt batteries, however Solar panels can deliver far more voltage than is required to charge the batteries. By, in essence, converting the excess voltage into amps, the charge voltage can be kept at an optimal level while the time required to fully charge the batteries is reduced. This allows the solar power system to operate optimally at all times.
The Hurricane white Lightning uses thicker winding which allows a higher level of current to pass to the grid tie or battery bank. This allows the generator to run both coolers and allow more amperage to pass which makes more wattage and has less resistance pass through the windings. We use the proprietary boost buck smart MPPT controller to maximize power output under all conditions. If you were able to follow the discussion essentially we have removed part of the balancing act. We are no longer limited having to use finer wire in windings to reach cut in points. We have less heating in the generators. Greater control over the turbines and finally more power output over time than anything in it’s class. We use our controller to get charging power out of turbines that other machines with lighter winding cannot. Our controller takes it another step further. The controller calculated the RPM of the generator based on the pulses of 3 phase power which flows through. The controller adjusts the resistance accordingly which takes a charge from the controller without applying to much resistance and killing the inertia of the blade set.

Protecting cover on it to resist the harmful effects of UV rays & other weather conditions is downright incredible. Regarding braking system, you’ll find it outstandingly versatile- both automatic and manual options are incorporated in it. So, overheating due to sudden fall of a few amps won’t burn your turbines out anymore. You can stop this system manually during a gale to lengthen its life. Necessary equipment is included and it carries a 1-year manufacturer’s warranty.
The peak power rating, Wp, is the maximum output under standard test conditions (not the maximum possible output). Typical modules, which could measure approximately 1 m × 2 m or 3 ft 3 in × 6 ft 7 in, will be rated from as low as 75 W to as high as 350 W, depending on their efficiency. At the time of testing, the test modules are binned according to their test results, and a typical manufacturer might rate their modules in 5 W increments, and either rate them at +/- 3%, +/-5%, +3/-0% or +5/-0%.[18][19][20]
Zoning—Most land has been delegated to various zones by a region's local government and building department officials (at the city, county, or state level [occasionally]). The zones control types of land use, such as agricultural, residential, commercial, and industrial, and include subcategories. Each type of zoning carries its own specific permitting restrictions, such as building height and property line offsets (required separation distance).
I myself have yet to get a power bill measured in watts. The measure that is used is kilo watt hours. This simply means the use of 1000 watts a load for an entire hour. This is used to calculate how much power is used and how to size renewable energy systems. In the discussion as it relates to small wind generators it would be it would give a better understanding to consider which would produce more kilo watt hours in a day.
There are multiple variables to consider when seeking out the best solar panels on the market. While certain panels will have higher efficiency ratings than others, investing in top-of-the-line solar equipment doesn’t always result in higher savings. The only way to find the “sweet spot” for your property is to evaluate quotes with varying equipment and financing offers.
This article is going to assume that you'll be building a grid-tie (or "on the grid") system. Grid-tie means that your house will still be connected to the utility company. The biggest benefit of staying on the grid is net metering: If you're producing excess power, you can actually sell it back to the utility company. Since your system will help produce green power for the grid, and reduce the overall strain on the utility company, they'll buy it from you at a huge premium. Because you're still on the grid, you'll still have power on cloudy days.
This step is better with two people, especially on a steep roof. Starting at the furthest corner from the location of your inverter, connect each the panel’s wires to the matching ones on its host inverter. Set the panels down straight, and use the click-in clamps that come with the racking system to clamp down the panel using your cordless drill/driver.

Local airport or weather stations can offer local wind data, but these data may be less reliable than actual site data. If airport data (typically recorded at 30 ft or 10 m above ground) or weather station data (typically recorded at 5 to 20 ft above ground) are used, inquire not only about the site's current equipment and location but also if it is historically consistent with the data collection equipment and siting. Equipment at these sites is not primarily intended for wind resource assessment, so it may not be positioned at an appropriate height or in a location free of obstructions. Unfortunately, airport and weather stations are usually far from the site of interest, with considerably different orography, tree cover, and monitoring height, making these data of questionable usefulness. Given the expertise required to effectively establish and correlate wind resource data, the data provided by airport and weather stations may only provide a rough screening assessment.[27]

Cities and suburbs had failed to keep pace with advances in alternative energy because they came of age in the sixties when everyone believed fossil fuel would last until nuclear power satisfied all our electrical needs. Now, as eagerness for the wind and solar power drives engineers and planners, preliminary studies suggest just about every North American community has geographic and weather conditions conducive to hybrid wind and solar power installations. We still can use our fingers to count the number of communities seriously considering investment in wind turbines.

Noise Issues: Small wind turbine noise is only slightly above wind noise. (Click On Video Tab Above) You may be able to pick out the sound of a hybrid wind turbine if you strain to listen but most people would not find it objectionable. However, if there is any doubt if your wind turbine will disturb your neighbor, be a good neighbor and have a conversation with your the family living next door in advance.
While we cannot defy the laws of physics as the current advertised power output values of many companies selling these type of products do. Hurricane products have a proven track record of producing more power over time than any of the other leading brands we have tested. Our buck boost mppt controllers and larger blade swept area and generator rotor and stators coupled with our buck boost MPPT controllers just make more power over time period. 

Research by Imperial College, London has shown that the efficiency of a solar panel can be improved by studding the light-receiving semiconductor surface with aluminum nanocylinders similar to the ridges on Lego blocks. The scattered light then travels along a longer path in the semiconductor which means that more photons can be absorbed and converted into current. Although these nanocylinders have been used previously (aluminum was preceded by gold and silver), the light scattering occurred in the near infrared region and visible light was absorbed strongly. Aluminum was found to have absorbed the ultraviolet part of the spectrum, while the visible and near infrared parts of the spectrum were found to be scattered by the aluminum surface. This, the research argued, could bring down the cost significantly and improve the efficiency as aluminum is more abundant and less costly than gold and silver. The research also noted that the increase in current makes thinner film solar panels technically feasible without "compromising power conversion efficiencies, thus reducing material consumption".[14]
As you may be aware, the Federal government will provide you with a hefty grant to reward you for being a part of the transition to renewable energy. Just how hefty, you ask? The incentive program will cover 30% of your costs. Not bad, right? For more free money, be sure to check out North Carolina State University's DSIRE. Many states, towns, and utility companies provide additional grants, tax breaks, buyback programs, and low-interest loans to help offset the costs of solar energy. DSIRE maintains an up-to-date list of these programs.
Mind you, in the upper Midwest, it won't produce near the power it did in the southern desert. It produces 5-6 Amps in "full sunlight" which means no clouds, no trees, no buildings. Low angle sun in the north doesn't deliver near the illumination that high angle southern desert sun does. This is why solar doesn't pay back in Detroit, Chicago or Minneapolis. Not enough sun.

We installed solar on our 45-degree metal roof last year. We previously had problems with ice sheets that would shoot off and put bystanders in danger. The panels do not melt the snow, but seem to be advantageously working as snow and ice-guards. Interestingly we have noticed that the light passes right through the snow and we still get power.

Is the wind resource at your site good enough to justify your investment in a small wind turbine system? That is a key question and not always easily answered. The wind resource can vary significantly over an area of just a few miles because of local terrain influences on the wind flow. Yet, there are steps you can take to answer the above question.

How accurate are these numbers? This is the energy production a good horizontal-axis wind turbine can reach, if installed at the perfect site and height. These are the upper limit though, if your turbine produces anywhere near the number predicted by this table you should be doing your happy-dance! Most small wind turbine installations underperform significantly, in fact, the average seems to be about half of the predicted energy production (and many do not even reach that). There can be many reasons for the performance shortfall; poor site selection,  with more turbulent air than expected often has much to do with it. The reports in the ‘real world’ section following below illustrate this point. Many small wind turbines do not reach 30% overall efficiency, some are close to 0% (this is no joke!), so these numbers have only one direction to go. For off-grid battery charging wind turbines you should deduct 20 – 30% of the predicted numbers, due to the lower efficiency of a turbine tied to batteries, and the losses involved in charging batteries.
It goes without saying that solar panels are essential for a solar power system. Actually, what you will probably need is known as a solar array. That is because each panel generates a small amount of electricity. The number of panels included in your solar array depends on how much power you need to generate. PV photovoltaic modules, often referred to as solar panels, convert light energy into a direct electrical current (DC). As solid-state devices, solar panels have no moving parts and are extremely reliable and durable compared to any other generator electronic technology. While solar panels have become somewhat commoditized in recent years, there are important differences in form, quality and performance that can impact both installation time and long-term system performance. Our web pages presents a selection of high-quality polycrystalline and monocrystalline solar panels with a variety of features and cheap price points to suite virtually any homeowners project.
Eventually, we should realize that net-metering is an incentive (needed at first to jump-start the rooftop solar industry), and that retail-wholesale rates are fairer to the utility and community all around. Net metering is when you over-produce in the summer, and get those kWhs back in the winter for free–you haven’t paid the utility for the transport and “storage” of the energy. Retail-wholesale is when the utility pays you the same rate they pay other power plants for each kWh (usually 1/2 to 1/3 the rate on your bill), and whenever you consume from the grid (evenings, cloudy days, winter), you pay the normal cost. That way, you pay the utility the infrastructure cost for moving that energy around. We have that here now, and I think it’s the way forward. But now, what they want to do is curtail the homeowner solar: using smart meters (and smart inverters), they would automatically shut down your production (turn off your inverter) when they have too much electricity (from their own solar farms). You would have to agree to this in order to be grid-tied, and remember, when they shut down your inverter, you can’t even use your solar power yourself. I think this is purely for profit motives and has nothing to do with the purported technical reasons.
Because wind speeds increase with height, the turbine is mounted on a tower. In general, the higher the tower, the more power the wind system can produce. The tower also raises the turbine above the air turbulence that can exist close to the ground because of obstructions such as hills, buildings, and trees. A general rule of thumb is to install a wind turbine on a tower with the bottom of the rotor blades at least 30 feet (9 meters) above any obstacle that is within 300 feet (90 meters) of the tower.[14] Relatively small investments in increased tower height can yield very high rates of return in power production.
This is a well-built solar kit from Renogy, and it is capable in many different scenarios, from being installed on top of an RV or trailer, to being installed as part of a larger solar array, the Renogy 100 watt Solar Starter Kit is a solid choice. The panel is made from monocrystalline, which is a more efficient material than polycrystalline (smaller and lighter). This is because the yield of silicone is greater and of a more pure consistency on the mono panels as opposed to the poly panels. The kit comes with a charge controller, called the Renogy Wanderer, meaning that you can expand your installation up to 400w, or 4 panels at a later stage when you decide to increase your solar capacity. Some consumers have complained about the quality of the controller, but the company has recently upgraded the controller – the Wander is a good value and works for most people.
Always, as in always, remember to take your first and most important safety precaution before you strap on your safety harness belt and take your first step up the tower: Shutdown the turbine and furl the blades before you ascend. If you leave the machine running, a sudden shift in the wind’s direction can spin the blades right into you, slicing and dicing you as if you were so much meat and cheese for a chef’s salad.
Product options: Your solar product needs to be your first consideration. Not every solar kit comes with the same products! Indeed one of the biggest problems with solar panel kits is that because they are targeting very price sensitive customers, many offer very low-quality solar brands. As well as a variance in equipment quality there is also a variance from website to website in what actually comes in a kit. Some solar kits come only with panels and inverters. Some kits include racking devices, while others include all the above along with minor electrical items (like circuit breakers) to offer a comprehensive solar solution. You will need to know what you require before ordering a kit and you will probably need to ask the installer you are going to get to install the system what he or she will need you to provide in terms of equipment.
You should know that we at Solacity love wind turbines! Can’t get enough of ’em. Where the neighbours see life-threatening, blade-shedding, bat-and-bird killing, noise-making contraptions, we see poetry in motion. Kinetic art at its finest; combining form, movement, and function all in one. We could stare at them for hours, while contemplating the meaning of life, the universe, and everything… and have… until the beer ran out. Despite all the information presented here, we are big fans of small wind turbines. This page is about informing you, so you can make a decision based on fact and not marketing hype.
One of the mistakes which is often made by the newbie who is trying to size a generator is that they buy specifically by a voltage classification. Remember as we discussed before windmill generator builder tend to rate their voltages at direct drive rpm 150-250 at a given voltage. This does not mean that if the permanent magnet alternator is turned at a higher RPM that the generator will not exceed 24 or even 48 volts. This is to say that in the case that you may have a hydro machine is cable of higher gearing and higher RPM that it may be better to in fact us a 24 or even a 12 volt rated permanent magnet alternator.
Making polycrystalline panels is cheaper and it's a newer technology. The silicon cools unevenly and creates many different crystals giving it a less uniform appearance. Polycrystalline solar panels tend to be the most affordable, but they also put out a little less power. Even so, poly panels are gaining in efficiency and will usually have the lowest price per watt.
"I have been looking for a reasonable DIY solar kit off and on for years. After coming across wholesale solar I had a few questions. From the first response I felt like I was respected and valued as a customer. Which is pretty rare these days. I would highly recommend Wholesale solar to anyone looking for a kit at a great price and fantastic service before and after the sale."
We are also seeing our local utility stigmatize distributed generation (their industry term for homeowner roof-top panels). A utility is a way for investors to park their money (build a power plant) and get guaranteed returns (protected by rate increases, where the PUCs are mostly regulatory capture). So they don’t like it when homeowners can produce their own power and zero out their electric bill. Most of them are building their own solar farms now, because it is cheaper than fossil fuels for daytime production, and because they still want to sell you power, not have you make it yourself. But if you think about it, it’s better to have 100,000 panels on 5000 roofs spread across the city than in a single location that can be shaded all at once by a single cloud–the power generation will be smoother.
The top features of the SMA SunnyBoy TL-US Series. Secure power supply, dual mppt tracking, and opti trac global peak. Secure pOptiTrac™ Global Peak, SMA’s shadetolerant MPP tracking algorithm, quickly adjusts to changes in solar irradiation, which mitigates the effects of shade and results in higher total power output. And, with two MPP trackers, the TL-US series can ably handle complex roofs with multiple orientations.

Step 2: Calculate your solar panel requirements. Assume you will receive 4 hours of full sunlight per day (check the DOE for exact amounts in your zip code), so a 100W panel will generate 400Whs of electricity (100W x 4 hours). Take your daily electricity usage (1,475 Whs) and then divide that by 400Whs per panel = ~3.7 100W panels or 4 with some cushion.
Net metering / net billing—For electric customers who generate their own electricity, net metering allows for the flow of electricity both to and from the customer. When a customer's generation exceeds the customer's use, electricity from the customer flows back to the grid, offsetting electricity consumed by the customer at a different time during the same billing cycle. In effect, the customer uses excess generation to offset electricity that the customer otherwise would have to purchase at the utility's full retail rate. Net metering is required by law in most U.S. states, but state policies vary widely. See also behind-the-meter.*
Wind turbines need wind to produce energy. That message seems lost, not only on most small wind turbine owners, but also on many manufacturers and installers of said devices. One of the world’s largest manufacturers of small wind turbines, located in the USA (now bankrupt by the way, though their turbines are still sold), markets their flag-ship machine with a 12 meter (36 feet) tower. Their dealers are trained to tell you it will produce 60% of your electricity bill. If you are one of those that is convinced the earth is flat, this is the turbine for you!

When it is sunny, regardless of outdoor temperature, pop cans (painted black) heat up very quickly. The fan drives cold air from inside of the home, through heated pop-cans and then back into the room. During this journey air collects the heat from can wall and brings it into the room. Read the following post if you are looking for more details about how solar thermal system actually works.
Wind turbines need a good wind resource. Off the grid homes on higher ground, with no obstructions between the turbine and the prevailing wind, are ideal, which is why coastal areas work well. The wind energy map can help you predict you average wind speed before installing your system. As a minimum, you need wind to hit the turbine at around 11 to 12 miles per hour. Local weather data will be helpful, but wind is very site-specific based on local terrain, site elevation, wind direction, and any obstructions such as trees or buildings. Check with your local code authority having jurisdiction because zoning and other planning restrictions may prevent you installing a turbine on your site.
Local airport or weather stations can offer local wind data, but these data may be less reliable than actual site data. If airport data (typically recorded at 30 ft or 10 m above ground) or weather station data (typically recorded at 5 to 20 ft above ground) are used, inquire not only about the site's current equipment and location but also if it is historically consistent with the data collection equipment and siting. Equipment at these sites is not primarily intended for wind resource assessment, so it may not be positioned at an appropriate height or in a location free of obstructions. Unfortunately, airport and weather stations are usually far from the site of interest, with considerably different orography, tree cover, and monitoring height, making these data of questionable usefulness. Given the expertise required to effectively establish and correlate wind resource data, the data provided by airport and weather stations may only provide a rough screening assessment.[27]
For a long time, we have been only familiar with solar as the best alternative energy source. Well, things have changed recently with many companies turning up with an amazing line of rooftop wind turbine kits. Coming in different sizes and capacities, you can easily find a matching wind turbine for your needs. Anyway, here we introduce you to a list of ten wonderful residential wind turbine kits.
If you’re hunting for a tiptop, ergonomic wind turbine that won’t sting your wallet, we recommend Mophorn 400W Wind Turbine. Though it comes with a nominal price-tag compared with our most expensive model, its multifaceted use will make your jaw drop. Locate it anywhere you please. Be it your resident, factory or office zone, you’ll be satisfied witnessing its unparalleled service everywhere.
This items including : 2pcs 400W wind turbine with grid tie controller ,2pcs waterproof grid tie inverter ! Why Off Grid Systems Should Include Wind? Wind provides power at night. Wind is strongest during the winter months when solar resources are limited. Wind provides power during poor weather conditions. Air density is higher in colder weather and maximizes power production.
It is important to note that we are dealing with the DC current. So the positive (+) is to be connected to positive (+) and negative (-) with negative (-) from Solar Panel to Charge Controller. If it gets mixed up, the equipment can go burst and may catch fire. So you need to be extremely careful when connecting these wires. It is recommended to use 2 color wires i.e. red and black color for positive (+) and negative (-).If you don't have red and black wire you may wrap red and black tap at the terminals.
These machines range micro turbines with a capacity of 50 kilowatts to large turbines with capacities in megawatts. Naturally, the price will go up as the turbine capacity increases. Another classification is according to the turbine environment. There are turbines for low wind areas that have a large rotor, and there are turbines for high wind areas with small rotors. Low wind turbines cost more than high wind units since they have to be a lot more efficient because of the absence of high wind speeds helping increase electricity generation.
Electric cost adjustment—An energy charge (dollars per kilowatt-hour) on a utility bill in addition to the standard rate in the tariff, which is associated with extra costs to purchase fuel, control emissions, construct transmission upgrades, and so on. These various costs may be itemized or rolled into one electric cost adjustment rate. Sometimes referred to as fuel cost adjustment.
Does anyone know about a way to create a little “solar garden” that could supplement our electricity, but without installing some of the permanent infrastructure needed on a house or garage? Anything that we could put out on a deck or hang out a window? I hope that isn’t too simplistic of a description, but I figured if anyone had good ideas, it would be you guys.
A battery will extend the payback. Batteries don’t last as long as panels and can carry a significant cost. In exchange for the cost, you get backup power for your house. My personal system, which is a bit of a cadillac and has a large lithium-ion battery backup (the most expensive upfront, but also the most resilient and longest-lasting), carries a payback period of about 20 years. I also have significant shading issues. So my house is pretty close to a worst-case scenario, and I end up with a whole-house generator that never runs out of fuel and will at least pay for itself over its lifetime.
Are you in the US? You can install solar panels and feed them into the grid if so. By law the power companies have to buy any electricity you produce. In some states it's much easier to implement than others though, check with local solar companies. You always use off the grid, but whatever you produce is fed into the grid during daytime. That offsets your electric bill. In most states the electric company just gives you a credit for whatever you produce, not a check in the mail.

Scientists from Spectrolab, a subsidiary of Boeing, have reported development of multi-junction solar cells with an efficiency of more than 40%, a new world record for solar photovoltaic cells.[11] The Spectrolab scientists also predict that concentrator solar cells could achieve efficiencies of more than 45% or even 50% in the future, with theoretical efficiencies being about 58% in cells with more than three junctions.
In addition to geologic formations, you need to consider existing obstacles such as trees, houses, and sheds, and you need to plan for future obstructions such as new buildings or trees that have not reached their full height.[31] Your turbine needs to be sited upwind of buildings and trees[32], and it needs to be 30 feet above anything within a 500-foot horizontal radius.[33] You also need enough room to raise and lower the tower for maintenance, and if your tower is guyed, you must allow room for the guy wires.
Creating a solar panel out of broken re-used solar cell pieces. I ordered a pack of these from http://siliconsolar.com (3$ for a bagful of them - you can order here). In addition, you will need some conductive copper mesh (available at most art stores), glue gun + sticks, a multimeter and a conductive pen (or any sort of conductive brush-on - I got my conductive silver pen here). In this tutorial I will try to explain the best technique I found to connect these broken cells, in order to create your own CHEAP solar panel.
A solar charge controller is a device which is placed between a solar panel and a battery. It regulates the voltage and current coming from your solar panels .It is used to maintain the proper charging voltage on the batteries. As the input voltage from the solar panel rises, the charge controller regulates the charge to the batteries preventing any over charging.
Well, coming to size and weight, it is obviously a bit larger and heftier. It has a rotor diameter of 5.6-feet and weight of 33 lbs respectively. However, it is easy for setting up on the rooftop of your home. It is also made of high-quality corrosion resistant materials for continuous performance anywhere. Use the link above to order a unit of the wind turbine.
Going solar has major financial benefits: it reduces your monthly electricity costs and can even increase the value of your home. Incentives like the federal tax credit for solar can reduce your net cost by 30 percent or more, but solar is still a big investment, and the price tag can result in sticker shock. To save money, it’s no surprise that many homeowners are considering DIY. Below, we break down the top pros and cons that you need to know about do it yourself solar energy before making a decision as well as the DIY solar process.
