I disagree, I have saw evidence the power companies always find a way to steal back whatever money you would of saved. There is a return on your own system if you do it right. There are solar panels that have 25 to 30 year warranty, and they should still produce power even after that. If you use Edison type batteries they will last decades, and when they go bad you can just refresh them. Once you have them paid for you no longer are paying for power anymore, and when everyone's power goes out, yours will still work.

I bought a diy solar panel guide before starting my project.  The one I chose is called Green DIY Energy.  In order to help people out, I bought several of the most popular guides and reviewed each of then.  Green DIY Energy is the most comprehensive with over 200 pages of ebooks and 6 DVD quality videos that cover the entire build process from start to finish.  I especially liked the videos.  When I built my first solar panel I followed along with the videos and at the end of the weekend, my solar panel was finished.

Rural America has relied on wind power for decades. Even after the government completed rural electrification in 1964, far-flung communities continued generating much of their own power from hybrid diesel/wind systems. And the windmill remains a fixture on most American farms-not because it represents a cute and quaint testimonial to times past, but because it makes perfect economic sense. Many large farms connected to the grid only as a back-up for their own more ambitious wind turbine installations. Most American farmers and small manufacturers recognize the wisdom of buying wind turbines instead of paying for electricity. Soon, owners and operators of large industrial and office complexes ought to see a considerable financial advantage in buying wind turbines, too.
In any generator whether it be a re manufactured delco permanent magnet alternator, our white lightning radial or even the larger axial flux designs different wire gauges can be used and are used for different reason for a given application. It is important also to understand that generally speaking when you are looking at a permanent magnet alternator for sale on our site ebay youtube Amazon ect when you see a voltage advertised such as frequently 12, 24, and 48 models this usually does not mean that there is some sort of internal regulator which limits the output voltage of the generator or pma to an adequate charging voltage level for an application This is one of the biggest mistake we see do it yourselfers make when selecting a generator. Typically sellers and manufacturers rate a permanent magnet alternator as for instance 12 volt when the RPM range of the generator is sufficient to reach Cut in Voltage to charge a given battery bank. Windmill, wind generators, wind chargers, or residential wind turbine kits terms we often see used interchangeably are trying to tell you that in a direct drive application with a particular blade set that they would use a particular generator for an application. So what’s the difference? Any style generator has a capacity “slots” or area that a winding can fit in. This will be unique to the particular generator. It is important to understand that within the working area different wire gauges can be used. In the area of the generator windings more “ turns” wraps or whatever terminology you prefer can fit in a given area with finer wire that with thicker wire as a matter of what will physically fit in a given stator coil, wrap , winding and or slot “again whatever terminology is appropriate for the given alternator.
A few years ago, some state governments started developing new standardized interconnection requirements for small renewable energy generating facilities (including wind turbines). In most cases, the new requirements are based on consensus-based standards and testing procedures developed by independent third-party authorities, such as the Institute of Electrical and Electronic Engineers (IEEE) and Underwriters Laboratories. Utility companies will typically require compliance with IEEE 1547, which addresses electrical safety requirements for wind turbine systems. Some utilities may require appropriate electrical listing before allowing interconnection of the wind system.
The term solar panels is often used for a few different types of products that produce energy by collecting sunlight. We most commonly use the phrase to refer to the type that converts sunlight directly into DC electricity. Less frequently, people will use the term in reference to solar thermal collectors, which typically heats a liquid such as water, or solar air heaters, which heats air directly.
FACT 2: This year, the tax credit has been improved, getting additional installation costs of the systems eligible in the IRS tax credits for small wind turbines. Also, new this year, ending Dec 31st is the removal of “cost caps” in the tax credit. So, this year, there is not a limit on how large a system you can buy, install, and claim in THIS TAX YEAR.

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.


Combiner / circuit breaker box is a key piece of equipment that begins to bring the pieces of equipment together that allows you to generate electricity. We use almost exclusively Midnite Solar and OutBack combiners and breakers because they are safe, durable and easy to wire. NEC (National Electrical Code) says that each series of strings of panels are to be wired to it's own circuit breaker. Midnite Solar and OutBack combiner boxes make this task easy providing a breaker to turn off and on each string for any purpose. The combiner box is usually located directly under a ground mount array.
After reading this article and investigating permits and all that BS, I can finally understand why so few people in this country have solar. My son and I installed my entire system, 3 kW, for $5,000, and after the 30% tax credit, my total cost was $3,500. That’s $1.17/kW. Inverters have come down since then and I could do the same job today for under $1/kW. For people with basic DIY skills including basic electrical wiring, it IS a simple process contrary to everything you read. In my area, there are no building codes, no zoning laws, no permits, (that’s what “freedom” looks like in case you’re wondering) so we did our own research and installed it how we wanted. We did a roof-top installation. Rail mounting systems are very expensive so we made our own using composite deck boards. They are some kind of recycled synthetic material and will last 200 years and are inexpensive. The solar panels come with a positive and a negative wire. You don’t have to try to figure out any wiring with those, they come prewired with male and female fittings so you can’t screw it up even if you try. After they are all hooked together, you end up with a positive and a negative wire. Those plug into your inverter in well-marked places so it is hard to screw this part up. If you do it at night, there is zero chance of getting electrocuted. From the inverter, you have two hots, a neutral, and a ground that plug into a 220-amp breaker in your electrical panel. Those places are also well marked in the inverter and hard to mess up. If you can install a water heater, you can install solar panels. It’s that simple. The biggest problem with solar is that everybody wants to make money off you along the way. The guy I bought my panels from wouldn’t even answer any questions because he was pissed I was doing my own installation. My electric co-op requires a professional electrician to pass everything off before they let you grid-tie. It was nearly impossible to find an electrician who would pass it off. Every one of them said the same thing, “If I didn’t install it, I’m not doing the inspection.” I finally got a guy out here. It took him 8 minutes to pass me off and sign the paper. I paid him $100. How long does it take to check a two AC wires (positive and negative) and three AC wires, plus two grounds? Give me a break. I would have given the guy $200 I was just so glad to finally get someone to look at it. I had everything open and ready when he got here. I walked him through it all explaining how each section was NEC compliant. He got his equipment out and did his testing and like I said, he was done in 8 minutes.
VAWT type turbines have no inherent advantage over HAWT type turbines. There, we have said it! VAWTs do not do any better in turbulent wind than HAWTs. Leaving the Savonius type VAWTs out (the type that looks like an oil drum cut in half – they have very poor efficiency anyway), both horizontal and vertical type turbines rely on an airfoil, a wing, to produce power. Airfoils simply do not work well in turbulent air; the wind needs to hit them at just the right angle and eddies wreak havoc. Couple that with the insistence of vertical axis turbine manufacturers to install their devices on very short towers or rooftops, and you get the picture. It will not work.

We hope you've found this guide to be helpful and informative. Home solar energy isn't terribly complicated, and with government incentives, it isn't terribly expensive either. In the long run, you can save a lot of money on your energy bills, and even make money by selling power back to the utility company. Once you know the parts of a solar array, the entire process is much less intimidating - it's just a matter of adapting the formula to your specific situation. Stop by SolarTown.com for more learning articles, solar news stories, affordable solar modules and components, or if you have any questions for a solar expert. Thanks a lot for reading, and have fun with your solar project!
Generally speaking, they work well in combination with solar panels, but can make sense on their own if your electricity rate is currently very high. Hot, sunny days don’t tend to be very windy, while those cloudy, sunless days are often much more windy. Wind turbines produce most of their energy in the winter, while solar panels do most of their work in the summer. A combination of the two is a great energy providing relationship for the environmentally conscious, or someone seeking to go “off the grid”.
Between maintenance and repairs, it would greatly help and keep your cost down if you can do some of the work yourself: Being able to safely tilt the turbine tower up or down will save you money. Understanding how the turbine works, how to stop it safely, how to trouble-shoot at least the minor issues can keep you in the black. We understand that installing a wind turbine is not for everyone. In fact, towers are dangerous, and for a good installation the devil is in the details. An experienced installer can make a real difference in putting up a turbine that will work better, and be more reliable over time. We really encourage you to have a professional installer to do the initial installation. However, throwing up your hands and calling your installer for routine maintenance, or every time there is a minor issue, will likely make you an unhappy wind turbine owner (even if it is your installer’s dream).
By the way, built with quality polypropylene and glass fiber, it gets by rough climate conditions out in the wild. Certainly, it is friendly for marine use as it endures saltwater corrosion. Moreover, the Windmill wind turbine features an automatic braking system to make it survive high winds. You can easily charge a 50Ah battery with the turbine that has a rotor diameter of 4-feet and weight of around 17 lbs.
Well, the Tumo-Int kit includes a wind generator, blades, charge controller, and other accessories like screws, nose cone, and etc. Further, the AC generator is a permanent magnetic triple-phase unit. Overall, it is one of the best residential wind turbine kits that you can try along with your existing solar array to add to energy production. Use the link above to buy a unit of the wind turbine.
Local utilities and regional power authorities are investing increasing resources to solar power generation. Both private and government-owned utility companies can leverage the recently-extended federal tax credits to encourage additional investments in renewable energy by their individual customers. As solar power generation increases on the large scale, prices for equipment will be driven down further, making it more feasible for a homeowner to invest in solar installations on their homes.
"Hello, we have lots of wind in our area and I want to add a wind generator to my off-grid home. It is always windy here." Many a homeowner has learn an expensive lesson the hard way because they have not taken the time to understand the basics of wind generation which is wind generators placed in areas of insufficient average wind are like dams placed in streams with little water, they do not work.
If a solar professional determines that your roof is not suitable for solar, or you don’t own your home, you can still benefit from solar energy. Community solar allows multiple people to benefit from a single, shared solar array that can be installed on- or off-site. Costs associated with purchasing and installing a solar energy system are divided among all of the participants, who are able to buy into the shared system at a level that best fits their budget. Learn more about community solar.
Most locations getting a permit is a relatively easy task – it doesn’t require being a master electrician. In the vast majority of places you don’t need to be a licensed electrician in order to do electrical work on your own home. Anyone who’s done electrical work on their house (like adding an outlet, or rewiring a bathroom) will likely have gotten a permit for it (or should have.) So should be familiar with most of the permitting process. If they haven’t done any electrical work like that previously, then probably installing solar isn’t a good time for them to learn electrical skills.
Wind is created by the unequal heating of the Earth's surface by the sun. Wind turbines convert the kinetic energy in wind into mechanical power that runs a generator to produce clean electricity. Today's turbines are versatile modular sources of electricity.[3] Their blades are aerodynamically designed to capture the maximum energy from the wind.[4] The wind turns the blades, which spin a shaft connected to a generator or the generator's rotor, which makes electricity.

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.

I bought a diy solar panel guide before starting my project.  The one I chose is called Green DIY Energy.  In order to help people out, I bought several of the most popular guides and reviewed each of then.  Green DIY Energy is the most comprehensive with over 200 pages of ebooks and 6 DVD quality videos that cover the entire build process from start to finish.  I especially liked the videos.  When I built my first solar panel I followed along with the videos and at the end of the weekend, my solar panel was finished.
The first words of everyone calling us are “the wind is blowing here all the time”. People consistently overestimate how windy their place actually is. They forget about all the times the wind does not blow, and only remember the windy days. Such is human nature. Before even considering a small wind turbine you need to have a good idea of the annual average wind speed for your site. The gold standard is to install a data-logging anemometer (wind meter) at the same height and location as the proposed wind turbine, and let it run for 3 to 5 years. Truth is that it is usually much too expensive to do for small wind turbines, and while logging for 1 year could give you some idea and is the absolute minimum for worthwhile wind information, it is too short to be very reliable. For most of us, the more economical way to find out about the local average wind speed is by looking at a wind atlas, meteorological data, airport information and possibly the local vegetation (for windy spots the trees take on interesting shapes).
However, I am curious as to why you are fighting the fixed charge? You stated yourself that you are essentially using the grid as a battery. At night, you are still using the full infrastructure of the grid (wires / poles / power plants / etc.), which costs money to maintain. So it only seems to make sense that you have to pay for that, no? Yes, you are saving the utility some fuel costs during the middle of the day when your solar is exporting, but there are still a lot of other fixed costs that need to be covered. If you don’t pay your fair share of fixed costs, other customers will essentially be subsidizing you. In CA, where I live, this indirect subsidy from net metering could grow to over 2 billion dollars in the next decade. Ironically, it will be mainly richer people who own homes and buy solar that will be profiting from this.
You’ve heard it on the news and you’ve read the latest reports. Solar power is projected to become cheaper than coal in about 10 years. Just consider the significant drops in the cost of going solar – since 2009, solar prices have dropped 62%! What was once a far-reaching solution to lowering your home energy bill has now become a reality in the life of many homeowners. In fact, DIY residential solar kits are appearing on the shelves of big box stores. As a homeowner, you’re ready to get in on the action! And with a DIY kit, how hard could it be to start saving money on your monthly electric bill? In this article, we’ll cover what you’ll do to install a home solar energy system and the pros and cons of the DIY method versus hiring the professionals.
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.

Since the energy output to the loads must be balanced by the energy input from your solar panels and wind turbine, we need to calculate your daily charge requirement in amp hours as that number will come in handy later. Take your total daily watt hours x 20% (rule of thumb) to account for losses in inverter, circuits and wire transfer. Now divide by the system voltage you chose based on the previous section and write this number down. This is the charge in amp hours your solar panels will have to provide each day to meet your load requirements you have set. Example 5,000 watts daily load total X 20% = 6,000 watts / 48 volt system = 125 amp hours that will need to be generated. Example #2, 5,000 watts daily load total X 20% = 6,000 watts / 24 volt system = 250 amp hours that will need to be generated.

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.
12V, 110Ah UPG AGM (absorbed glass mat) batteries are shock-resistant and maintenance-free, producing higher cranking amps, extremely low (1–3%) self-discharge rate and greater vibration resistance. Non-hazardous, non-spillable battery design requires no water additions and rugged construction withstands harsh conditions. Two batteries included in this offer, providing a 12V, 220Ah system.
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.
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.

Where the reputable, and more expensive manufacturers are good in honouring their warranties, you are likely on your own with the cheap stuff. Even with a good warranty, take our word for it that you would much rather not make use of it. Even if the manufacturer supplies replacement parts, it is still expensive to install them. Not to mention that your turbine will not be making energy meanwhile.
Research small wind turbine companies to be sure they offer certified turbines and that parts and service will be available when you need them. Ask for references from past customers with installations similar to the one you are considering. Ask the system owners about performance, reliability, and maintenance and repair requirements, and whether the system is meeting their expectations. Also, find out how long the warranty lasts and what it includes.
As you know, your power meter measures the amount of electricity you take from the grid. It is very likely, however, that you'll need to get a special meter that is able to spin backwards - without it, you can't accurately measure the amount of energy you're giving back to the grid. In most cases, you can call your utility company and they will provide one of these meters for free. As I said before, having a power station in the middle of the grid - even a tiny one - takes a lot of load off of the system, and the utility company will gladly assist you with your solar home.
At the back side I made a big circular hole just behind the inverter fan for fresh air suction from the outside. Later I covered the hole with plastic wire mesh. A few small holes are also made for inserting the wires from the solar panel, charge controller and inverter to the battery and AC output to the appliances. At both sides 3 horizontal holes are provided for sufficient ventilation. A glass window is provided at the front side to view the different led indications on the inverter.
Home wind turbines are electric generators that convert wind energy into clean, emission-free power. Although most large wind farms exist to power certain towns and communities, there are also smaller wind turbines for homes and homeowners. These smaller turbines can be installed on any part of your property to cover some or even all of your monthly energy needs.

Solar panel conversion efficiency, typically in the 20% range, is reduced by dust, grime, pollen, and other particulates that accumulate on the solar panel. "A dirty solar panel can reduce its power capabilities by up to 30% in high dust/pollen or desert areas", says Seamus Curran, associate professor of physics at the University of Houston and director of the Institute for NanoEnergy, which specializes in the design, engineering, and assembly of nanostructures.[27]


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.
I think there’s some animosity between people who mistakenly think that power companies are against solar panels on homes. What’s often overlooked though is that power companies don’t just charge you for power. They are also charging you for all of the infrastructure required to deliver that power to you. So, if your normal power bill is $100 and through use of solar panels and net metering, you drive that cost down to zero, the power company isn’t recovering any of the costs associated with your home being tied to the grid.

"Wholesale Solar and John Grenvik where a pleasure to do business with. I found it interesting and quite unusual that John would not let me up-size my battery bank beyond what my panels would support on my off grid system, as he said I would be destroying the batteries by their not getting a full charge. How's that for looking out for the customer even at the expense of additional sales."
Local utilities and regional power authorities are investing increasing resources to solar power generation. Both private and government-owned utility companies can leverage the recently-extended federal tax credits to encourage additional investments in renewable energy by their individual customers. As solar power generation increases on the large scale, prices for equipment will be driven down further, making it more feasible for a homeowner to invest in solar installations on their homes.
Our recommendation is the Renogy 100 Watts 12 Volts Monocrystalline Solar Starter Kit. It features a highly efficient monocrystalline panel, is built in the USA and offers good value as a starter kit.  Because it uses monocrystalline panels, it is lighter (19.8 lbs) and smaller dimensions that kits that use polycrystalline panels, which makes a difference for RV or boating applications. It can also be expanded up to 400Ws.

IE: 5 - 13 watt light bulbs X 5 hours per day = 65 watts. 18 CF refrigerator @ 5 amps x 120VAC = 600 watts x 6 hours per day = 3,600 watts. THIS IS IMPORTANT: When we say "list your loads", we mean all your loads. From the cell phone chargers to a hair dryer. Need Help? If you download the Excel worksheet you will only have to indicate how much of each piece of equipment you have and how long your run it.
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.
Wholesale Solar has designed the following Hybrid Gridtie System with Battery Backup for emergency power outages. A sophisticated Outback Power GVFX3638 vented inverter allows your gridtied solar panels and wind turbine to charge a battery bank, even when the grid goes down. With the help of a Wholesale Solar technician, you can select the appliances that you want powered during an emergency power outages, and then choose the correct battery bank size.
Some utilities require small wind turbine owners to maintain liability insurance in amounts of $1 million or more to protect them from liability for facilities they do not own and have no control over. Other utilities consider the insurance requirements excessive and unduly burdensome, making wind energy uneconomic. In seven states (California, Georgia, Maryland, Nevada, Oklahoma, Oregon, and Washington), laws or regulatory authorities prohibit utilities from imposing any insurance requirements on small wind systems that qualify for net metering. In at least two other states (Idaho, Virginia), regulatory authorities have allowed utilities to impose insurance requirements but have reduced the required coverage amounts to levels consistent with conventional residential or commercial insurance policies (e.g., $100,000 to $300,000). If your insurance amounts seem excessive, you can ask for a reconsideration from regulatory authorities (in the case of private investor-owned utilities) or the utility's governing board (in the case of publicly owned utilities).
How high is your tower? Hands down, the biggest mistake a homeowner can make with a small wind turbine is putting the turbine on too short of a tower. Like solar in the full sun with no shade, any renewable energy source must have good access to the fuel that drives the electricity. There is nearly 100% more power available in 10 MPH winds than 8 MPH winds.
A good article What could go wrong with self installation? Let me tell you a couple of things that go wrong if work is not done by professionals. If wiring is too small, you could get into problems instantly. Wiring could turn red hot ! What could possibly go wrong with 5,000 watts DC at 72 volts on a ground mount being touched by children after a rain ? What could go wrong with someone not familiar with Ohm’s law as it relates to cable size ? What could go wrong with using circuit breakers not designed for Direct Current, that fuse instead of open up ? What could go wrong with an inverter mounted where it can get wet in the rain ? What could go wrong with forgetting proper grounding ? What could go wrong with installing equipment that doesn’t isolate itself from the power line (during power outages) other than simply electrocuting the power lineman ? Do it yourself ? Better know what you are doing !
These small wind turbines are perfect for someone who wants to experiment with wind energy or for a small cabin system. Comes complete with 20 feet of wire, ring terminals to go to your 12V battery and everything else you need to build your turbine. Starts charging at wind speeds of about 15 mph. Blocking diode is installed and no charge controller is required. Designed for medium wind speed areas. We can not accept returns for turbines damaged by high wind speeds. Output max. 2.25 amps @ max. 25V. Optimum wind speed: 15 mph
Several companies have begun embedding electronics into PV modules. This enables performing maximum power point tracking (MPPT) for each module individually, and the measurement of performance data for monitoring and fault detection at module level. Some of these solutions make use of power optimizers, a DC-to-DC converter technology developed to maximize the power harvest from solar photovoltaic systems. As of about 2010, such electronics can also compensate for shading effects, wherein a shadow falling across a section of a module causes the electrical output of one or more strings of cells in the module to fall to zero, but not having the output of the entire module fall to zero.

Interconnection standards—Specifies the technical and procedural process by which a customer connects an electricity-generating device to the grid. Such standards include the technical and contractual terms that system owners and utilities must abide by. State public utility commissions typically establish standards for interconnection to the distribution grid, while the Federal Energy Regulatory Commission (FERC) establishes standards for interconnection to the transmission grid. While many states have adopted interconnection standards, some states' standards apply only to investor-owned utilities and not to municipal utilities or electric cooperatives.*


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.
"Purchased a 6kW off grid system from Wil. I had no previous solar experience, some previous homeowner type electrical work: installing a new circuit, adding a sub panel, etc... Bolted everything together following the manuals, closed the breakers and all worked. Had a few questions/calls on tuning and maximizing performance and all were answered promptly."
