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”.

MMM, long time reader first time commenter. Excellent to see you finally got your array up and running and that you shared your DIY report for fellow folks not afraid to get their hands “dirty” in saving some cash for a great project. As a professional solar installer I must politely request you remove the photo of the L-foot lag screwed directly to the roof. National Electric Code and industry best-practices require and suggest a metal flashing that goes over the lag screwed and under your shingles to create a waterproof seal. Through-The-Roof sealant is added protection but not enough stand alone. I look forward to further DIY posts as well as a continued look at your solar power production over time as power prices continue to rise. Bike on, my good man! Cheers, Sam in SW Montana


Before you begin, you'll need to make sure that what you're doing is legal. Call your local government and find out what kind of building permit you need - often, for renewable energy, they will waive the permit fee. Also be sure to contact an electrician. Even if you are installing the entire system yourself, you'll need to have it inspected, just to be safe. An electrician can help with problems or opportunities you may have missed. Be sure to read DSIRE carefully - It has some information on state and local regulations.
Airport Wind Speed Data: Though not definitive, your nearby airport can provide good information about the average local wind speed for your area. You need to be a little cautious because the information recorded at the local airport may be on land that is flatter and less obstructed than your lot and is usually measured at heights of 20 - 30 feet off the ground.

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 ability of an off-grid inverter to surge to a higher level than its rated continuous output for a short duration to turn over the locked rotor of large loads like well pumps is critical. The inverter specifications that should be looked at are the Maximum Output Amps and the AC overload capability. If there are large loads a good number to look for is a five second surge capability of at least 1 ½ times the rated output of the inverter. If you have a deep well pump, the minimum requirement may be 3X the continuous run amps.


And even after you learn enough to know what all that means, you now have to make a decision about quality. Which kits are better? How do I know? So now you’re scouring consumer reports charts, reading reviews, wondering where the panels were made, and if that manufacturer even has a phone number (some solar panel kit manufacturers are in China and have zero customer service).
What’s surprising about the Mathers’ situation is that their local wind speeds are not ideal, yet home wind power works beautifully for them. “Technically, if you look at wind maps, we’re in a bad location for wind, but we wanted to be off-grid for environmental reasons,” Cam says. The biggest issue with the Mathers’ property is that they have too many trees, and even though their small wind turbine is easily 40 feet above the tree line, the landscape slows down the wind. Wind still makes sense for them, though, because they’re off the grid, so their only electricity is what they produce and then store in batteries. They started with solar panels, but adding a wind turbine to the mix made the whole system much more stable and efficient — a major benefit when you’re solely responsible for generating your own electricity.

By now you are probably thinking “why would these guys tell me the truth? They sell small wind turbines!”. Yup, guilty as charged. We also want happy customers, and the two are not reconcilable unless we are upfront with you, our customer. Truth is, wind turbine sales are a tiny part of our revenue, and while we would regret losing you, we will still be able to put food on our kids’ plates.
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!
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.
Deciding the size of your system is the next step. With a grid-tied system, size is less critical, because the grid supplies power when your PV system falls short. Systems as small as a couple hundred watts are practical, but you can also install panels that will produce enough electricity for all your needs. Review how much electricity you use now, and then estimate what you will be able to save by applying conservation and efficiency measures throughout your home. This will give you an idea of how big a system you’ll want to build. You certainly can build a system smaller than this, but it may not pay to install a larger one. Look up your state on DSIRE to learn about net metering rules where you live, including how much you can get paid for generating excess power.

The basis of producing solar panels revolves around the use of silicon cells.[41] These silicon cells are typically 10-20% efficient[42] at converting sunlight into electricity, with newer production models now exceeding 22%.[43] In order for solar panels to become more efficient, researchers across the world have been trying to develop new technologies to make solar panels more effective at turning sunlight into energy.[44]
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.
Before you go searching for websites that sell solar kits the first thing you should do is get at least one quote from a full-service solar company. You can do that online through our solar panels estimator. The advantages of this are that you find out what the cost of the competing option to a DIY solar project (a full-service installation) costs. You need to know this to know whether all the individual costs you face when doing a DIY installation (panels, inverters, racking, electrical sundries, service board upgrades, installation labor, permitting and inspections) are actually worth it. Click here to learn how much a solar installation for your home will cost.
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.
Controller – the charge controller is basically a safety feature that looks after the battery bank. It monitors the amount of energy stored in the batteries and protects the batteries from overheating when they are fully charged. When the batteries are fully charged the controller diverts the energy to the dump (see next component). We recommend MPPT charge controllers. They are a bit more expensive than PWM controllers, but they are much more efficient.
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.

Great article. I had solar panels fitted around 2 years ago here in the UK, costs are a lot higher and our panels are South-East facing. Even so our electricity bills are around a third lower than they were & this year has seen an improvement on that because we charge phones etc and run the washing machine / dishwasher during the daytime whenever possible. Payback is looking to be around 7 years. The only negative is that we had to pay for mesh around the panels because for the first two Summers we had a problem with jackdaws trying to nest under them causing an almightly racket, large (6+ feet) piles of twigs and attacking the wires.
So get ready to spend many hours and many months reading manuals, calling help lines, watching Youtube videos over and over to be sure you know which wire is which, reading blogs, talking to friends or family who know more than you about this, sitting on hold or standing in line waiting to get your permitting questions answered, figuring out what tools you need… shall we go on?
Now, it is time to consider site specific issues associated with installing the hybrid solar wind system. The most important factor in maximizing the performance of your wind generator is the correct siting on your property. The better the siting, the greater the performance. Small increases in average site specific wind speeds result in dramatic increases in energy output of your wind generator. For example, an increase in wind speed of 10% (10 mph - 11 mph; 4.5 m/s - 5 m/s) results in approximately a 30% increase in the power available from the wind. Therefore, the better the location the better the performance. As a rule, the small wind generator should be mounted as high and as faraway from obstructions as possible.
In rigid thin-film modules, the cell and the module are manufactured in the same production line. The cell is created on a glass substrate or superstrate, and the electrical connections are created in situ, a so-called "monolithic integration". The substrate or superstrate is laminated with an encapsulant to a front or back sheet, usually another sheet of glass. The main cell technologies in this category are CdTe, or a-Si, or a-Si+uc-Si tandem, or CIGS (or variant). Amorphous silicon has a sunlight conversion rate of 6–12%
Nominal voltage [17]refers to the voltage of the battery that the module is best suited to charge; this is a leftover term from the days when solar modules were only used to charge batteries. The actual voltage output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage at which the module operates. Nominal voltage allows users, at a glance, to make sure the module is compatible with a given system.

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.

Thanks for the write up. Very interesting. Being concerned about the carbon output as well, has there been any research into the CO2 produced in the production of the material being installed? I was really convicted about this concern when I started considering the CO2 given off by things like spray foam on building projects I have done in the past.
Flagging—The deformation of local vegetation toward one direction, indicating the prevailing wind direction and relative strength (more formally called Krummholtz formation). Flagging is sometimes used with the Beaufort scale to generate an initial estimate of local site conditions. (Note: flagging does not determine the wind resource, but is a confirming indicator of it. For example, sometimes flagging is the result of sunlight availability, or trimming of tree branches near electrical lines. The assessor needs to understand when flagging is relevant, or when it is a confirming indicator of another condition at the site.)
The included charge controller is a PWM unit and it features overload and short circuit protection. By the way, the wind turbine doesn’t come with a pole that you should buy separately. Well, you never need a technician to set up this off-grid power kit. You can easily put the parts together to bring into life a cool off-grid power system. Eco-Worthy also sells 500W, 600W, and 1400W variants of the wind-solar kit.
This solar kit is ideal for running items like small pumps and lights, and can be used for charging up your battery pack. There are 4 x 100w polycrystalline solar panels that connect up to a two diode junction for better performance. The charge controller that comes with the kit is also one of the better units that we have reviewed. The charger includes a 3 stage control, multi colored status LED, temperature compensation and a manual or automatic charge equalization feature. This kit is more expensive than the 400W Renogy as it comes with an inverter.
The first step to planning your system is to evaluate rebate options and obtain permits. Your local power utility has rules you must follow when you hook the finished system to the grid, and building codes may also apply. In addition to federal incentives, states (and even some cities) offer rebates to help with the cost of the system. Understanding the local rules before you start will save you frustration later.

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.
