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.

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.
You need to make sure that all the tiny little lines in the negative side of the cells are interconnected (a way to gather all the electrons from the surface). This step is not necessary for all cells, only for the ones like in this picture, which don't have any connection between the lines on the surface. you can use the conductive pen to draw a thin line which connects all of them. Once you do that, you will immediately see the voltage rising for that specific cell.
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!
Here in Orange County, New York, the local Utility provider is Orange & Rockland Utilities. A Doctor here solarized his home and they only gave him pennies for his electicity that he sent back through his meter to the grid. As usual a Large Monopoly sticks it to the consumer when he tries to save energy and avoids their price per Kwh. As we speak, they are asking for another increase in rates! How much greed can there be?
turbine installed and running - sustained a storm last night with steady winds before the storm of up to 25 mph, then the storm hit and gusts in excess of 40 mph - the wind turbine sustained no damage and is still running this morning. My sister's house lost power for 5 hours, however, the turbine is set up to run the ice box, the ice box never lost power, everything is still... [green backup power]
I had a very good experience ordering online with GoGreenSolar.com. After thorough online research, I found GoGreenSolar offered the components I was looking for, available for delivery at the most affordable prices, including shipping and handling. I basically ordered the parts to put together my own energy saving solar panel system. They were not only delivered in a very timely manner, but all of the parts were quality built, nothing broken or damaged. I would definitely recommend going to their site when considering solar panels.
Throughout the guide, I'll be providing links to articles from SolarTown.com's learning center. This guide is meant to be very broad, so that you know what to keep in mind and what to plan for. Once you start researching individual products, though, you'll probably want a little more specific information. Hopefully, these links will address your questions. If anything you need to know isn't covered, feel free to surf over to our community page and ask an expert solar installer.

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.
The last piece of equipment you’ll need to consider when considering a DIY solar energy kit is whether you intend to have battery backup or not. Your system does not have to have a battery, but, if you do, you can use the battery to store unused energy (instead of feeding it back into the grid). That way, you’re even less dependent on the grid for energy, for even when the sun is not shining or during blackouts, you can draw on your stored energy in the battery to continue to power your home.
Whether the system is stand-alone or grid-connected, you also need to consider the length of the wire run between the turbine and the load (house, batteries, water pumps, etc.). A substantial amount of electricity can be lost as a result of the wire resistance—the longer the wire run, the more electricity is lost. Using more or larger wire will also increase your installation cost. Your wire run losses are greater when you have direct current (DC) instead of alternating current (AC). So, if you have a long wire run, it is advisable to invert DC to AC.[34]
Of course, the optimal situation is when you consume your own electricity during the day, for example charging an electric car, plus enough to zero your bill. Then, the cost to you of the electricity is whatever your PV installation costs were over the lifetime of the system, for example $10K for 5kW of panels generating 20 kWh per day on average makes 146 GWh (over 20 expected years) = 6.85 cents/kWh (and 0 cents for every kWh after 20 years). For this reason, electric cars and PV solar go very well together, each amplifying the savings from the other.
However, there are tiny ones (1kW – 2kW) that are available from $800 upwards. These turbines come with a small start up speed and torque to provide optimum power output in regular conditions. Although they may not provide for luxurious power usage for an average household, they can pretty much meet some of your electricity needs throughout the year. These are ideal for consumers living in remote areas. Most small wind generator suppliers charge no more than $300 for shipping.
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.
Great questions….Offsite is not too bad, the inverter doesn’t have to be adjacent to the panels and depending on your climate can easily be outside. Heat is the biggest degrading factor on the inverter’s efficiency so a shaded location is perfect. To calculate the size of wire from the panels to the inverter I used the company (Alt E) that I bought the panels from. They also provided a basic wiring diagram for the permitting process. You can also do the math yourself and they (Alt E) have some very detailed videos to help. Basically, you need the percent loss your are willing to accept (I used 1%), max average temp (+10 degrees) of the site, the distance and the amperage of the array and the max voltage…..For example my Vmax was 450 at 9amps running 200′ in Florida (I think I used 31 degrees C ) and ended up with 8 AWG copper. Not cheap but easy enough.
Excellent article as always MM, we’ve been anxiously waiting for you to post it! This is something my wife and I have been researching for a while as well, especially since we got an electric vehicle. I would really appreciate more information on your financial numbers, especially how you calculate the returns and payback period. I did some math on this recently and found payback times on a 10KW DIY install were closer to 40 years before breaking even. This contrasted harshly with the numbers (8-10 years) that a local solar company was advertising. Not sure if they’re being misleading or if I missed something.
I’m working on getting the power company (which is owned by our small city) to change this policy, however, since they recently announced a goal of moving to 100% renewable power by 2030. I’m one of the few people who will make the switch even if it costs me MORE than coal-generated electricity, so I don’t actually care about the payback period. But most people require a financial incentive to make a change.
With the increasing levels of rooftop photovoltaic systems, the energy flow becomes 2-way. When there is more local generation than consumption, electricity is exported to the grid. However, electricity network traditionally is not designed to deal with the 2- way energy transfer. Therefore, some technical issues may occur. For example in Queensland Australia, there have been more than 30% of households with rooftop PV by the end of 2017. The famous Californian 2020 duck curve appears very often for a lot of communities from 2015 onwards. An over-voltage issue may come out as the electricity flows from these PV households back to the network.[58] There are solutions to manage the over voltage issue, such as regulating PV inverter power factor, new voltage and energy control equipment at electricity distributor level, re-conducting the electricity wires, demand side management, etc. There are often limitations and costs related to these solutions.
Governor—A device used to limit the RPM of the rotor. Limiting RPM serves to reduce centrifugal forces acting on the wind turbine and rotor as well as limit the electrical output of the generating device. Governors can be electrical, also know as "dynamic braking," or mechanical. Mechanical governors can be "passive," using springs to pitch the blades out of their ideal orientation, or an offset rotor that pitches out of the wind, or "active" by electrically or hydraulically pitching blades out of their ideal orientation.*
You start by monitoring your energy consumption. You need to have a good idea of how much energy you consume on the average day to determine how big of a solar energy system you’ll need. On top of that, you’ll also need to know how much money you have to spend – keeping in mind that the most expensive solar panels might not be the most cost effective for your needs.

Jump up ^ da Silva, Wilson (17 May 2016). "Milestone in solar cell efficiency achieved". ScienceDaily. Retrieved 9 September 2018. A new solar cell configuration developed by engineers at the University of New South Wales has pushed sunlight-to-electricity conversion efficiency to 34.5% -- establishing a new world record for unfocused sunlight and nudging closer to the theoretical limits for such a device.

This is great. With all the things going on around us about solar energy we forget that fundamentally solar energy is the natural evolution of the electricity, power and energy industry. If the consumer also becomes the generator and all are electricity self sufficient where solar solutions seem to be going then imagine what fantastic future we can build for ourselves.
$60) dollars a sq ft range with a 50 percent mix, making it way more expensive than any other roofing material or solar panel. It also does not appear to lend itself to roofs that have hips, dormers, multi planes, etc. Who knows, when it finally comes to market cost may come down, but today its in the rich folks only bracket I believe. I don’t see it being a commodity dyi item for installation like this article any time soon.
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.
There are various kind of batteries. Car and bike batteries are designed for supplying short bursts of high current and then be recharged and are not designed for a deep discharge. But the solar battery is a deep-cycle lead-acid battery that allows for partial discharge and allows for deep slow discharge. Lead acid tubular batteries are perfect for a solar system.
“I don’t live in Colorado. How much juice will I get out of it where I live?” This part is fun: The National Renewable Energy Lab runs a great, free calculator called PVWatts that does it all for you: factoring in average weather and solar angles in your area, even allowing you to specify solar panels placed at any crazy angle you like. (In other words, your house doesn’t have to have a perfect South-facing roof).

If you go with crystalline modules, solar module racking (the bits and pieces that hold your panels in place) may be the most important part of your project. Here, we'll discuss a few things to keep in mind while you determine where you want your solar panels to go. If there's too many obstacles to crystalline panels, you'll definitely want to consider thin-film instead.
This can get a bit tricky, but once you get the hang of it, can be done fast enough. First, some technical notes: In order to get higher voltage, you need to connect two cells in series. This means that the negative part of the first connects to the positive part of the second. As you continue to add more cells in series, you will get a higher voltage from side to side on your solar strip. This is all good, but if your cells are small-ish, they won't generate much amperage. So even if you have a high voltage, you probably won't be able to give it any load (probably will hardly light an LED). In order to get higher amperage through the circuit, you need to connect cells in parallel (positive side to positive side, negative side to negative side). When you do this, make sure the positive and negative leads (copper mesh in this case) don't short themselves out.

Step 3: Estimate your battery capacity. We need to factor in bad weather, so we will multiply your daily electricity usage by 2 days as a safety measure in case we don’t have enough sun to charge our batteries. Because we don’t ever want our batteries to discharge below 50%, we will then multiply this number by 2. So your daily electricity usage is 1,475 x 2 days x 2 (50% capacity) =  5,900Whs.
