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.


DIY solar panel kits are specifically designed for home do-it-yourselfers, experimenters, students and anyone interested in learning about solar power from the ground up. If you’re one of those people who learns best by doing…or just love tinkering around with things and putting them together, the a DIY solar panel kit is probably the best, most exciting and most fulfilling way to learn about solar energy.

My position is that solar is not good enough for places that are not sunny most of the year, and that includes most of the North East USA. In a few years, when the panel efficiency gets greater with the retail sale of dual-gate and possibly tri-gate or more gate solar panels, then we will have something. Folks should install what works right for their area, and in much of the US, solar is a good idea; just not all of it, not yet.


Most home solar kits are designed for off-grid use, which means you can’t use them and remain connected to your utility. If you’re an average homeowner, going off-grid is probably not in your best interest – being able to access utility-generated electricity is important if your solar energy system doesn’t produce enough electricity to meet your needs at all times of the day throughout the year.
Many municipalities must get kick backs from the electricians they are protecting with these mazes of codes.. Most solar/wind retailes have resorces and calculators to help you calculate fusing and wire size.. Changing out things in your own home even as simple as installing a GFI outlet require a permit and a certified electrician making them outragously expensive.. In my example you could be looking at $400 and the inconvience of having people nosing around your home several times.. If that inspector finds somthing he does not like you could be looking at hundreds or thousands of dollars more in costs or having them slap a condemned sticker on your home.. I have a 4kw system planned and am praying that the County Inspector is not a pain.. Could put in an isolated system with no inspection using my amateur radio license but I want interconnect with the power company.. Local power company has a very simple application system for interconnecting and all they require is an external labeled disconnect and a status light they install on the pole at the transformer cost $50..

Square wave inverter is cheaper among the all but not suitable for all appliances.Modified Sine Wave output is also not suitable for certain appliances, particularly those with capacitive and electromagnetic devices such as: a fridge, microwave oven and most kinds of motors.Typically modified sine wave inverters work at lower efficiency than pure sine wave inverters.

Betz limit—The maximum power coefficient (Cp) of a theoretically perfect wind turbine equal to 16/27 (59.3%) as proven by German physicist Albert Betz in 1919. This is the maximum amount of power that can be captured from the wind. In reality, this limit is never achived because of drag, electrical losses, and mechanical inefficiencies. See also Cp.*
GoGreenSolar: A solar provider since 2006, GoGreenSolar offers products, design services, and installations. The site offers a wide selection of solar panel kits and products. They claim to offer a robust complement of installation and troubleshooting services but I’m not sure how much service this gives you in terms of design. They offer some very cheap solar kits using brands that I have never heard of but if I was going to consider buying a kit from them I would decide what brand of solar panels and inverter I wanted before I spoke to them. I would not buy their cheapest kits as these contain brands I don’t trust.
Do it yourself (DIY) Solar; You Are Not Alone Yes, this AZ homeowner installed this large Outback Radian off-grid solar panel kit, 2 wind turbines and built his own homemade ground rack. Well done! The idea of a DIY (Do-It-Yourself) solar install makes some homeowners hesitate for one simple reason: they're nervous to go it alone. From permits to the install itself, people fear the thought of getting it wrong. Consequently, Blue Pacific Solar® decided to take this fear right off the table and address what customers need: a dedicated energy consultant assigned to you after your purchase to provide a single contact point. Your technical adviser will answer any questions and guide you throughout the entire process offering their expertise as part of the package. Moreover, the DIY kits' benefits include access our nationwide permit service so buyers have their entire install process streamlined and a backup professional in the wings to steer them through any questions that arise during the install. Whether the install is performed entirely by the homeowner or in conjunction with a local electrician, the cost savings is too compelling to ignore and too practical with the support by us, to do it any other way if the homeowner is remotely inclined to take on the job.
Let’s also remember the carbon cost of fossil fuels is not just limited to the consumption of the fuel at the point of power generation. It takes a huge amount of energy to bring the oil or natural gas to the point of generation. From manufacturing of the steel well casing and pipeline, drill rig operation, fracturing operations, transport, and refinement. Not to mention the small army of oilfield workers driving around the field each day I F-150s to maintain the equipment, gauge tanks, etc. Then you have to consider the inefficiencies of transporting the energy from fossil fuel generation from centralized locations long distances to the point of consumption; whereas distributed power (i.e., rooftop solar) is consumed at the point of generation typically. I don’t have hard numbers, but I’d bet a lot that the one-time carbon cost of manufacturing the panels is less than the total carbon cost of bringing a similar amount of carbon-based fuel to market once you factor in all the above (exploration, development, transport, refinement, generation, and distribution).
Flagging, the effect of strong winds on area vegetation, can help determine area wind speeds. Small wind site assessors can help you determine whether you have a good wind resource on your site. State or utility incentive programs may be able to refer you to site assessors with training in assessing the wind resource at specific sites. Computer programs that estimate the wind resource at a particular site given specific obstacles are also available. Site assessors and computer programs can help to refine the estimates provided on wind resource maps.
After the photons are transformed into electricity, the panels direct this energy to power the home. Some homes, those independent of the utility grid, must rely on battery storage to store energy, yet they may also have to rely on backup generators when there is too much demand on the size of the system. Many people use solar in tandem with the utility companies so that they have a convenient back-up during fluctuating periods of energy. This net metering partnership is a bit involved, but it has also been evolving to become more effective as more and more people choose solar to provide the bulk of electricity to power their homes.
