Q: ) what is absolutely needed to hook up a solar panel to grid tie, what permits and/or inspectors are needed?2) if we know how many KWH's we use per month, do we just divide by number of hours per month to find out average KW usage?3) what is an estimated ratio of DC to AC transformation/convertion @ 30 C?4) do the solar panel voltages have to be the same? what would happen if the voltage going into the house is greater/lower than that of the house's defualt voltage5) for added chance of getting 0 pts add some contrators that do business in ohio for installing solar panels or sell them: The okorder The reference section has all the formulas you are looking for and there is a list of dealers by state, plus various state rebate information. Yes, you can hook up different panels to the same system. There are special controllers that regulate the voltage. I'm more of a hands on nuts and bolts guy so I can't help you with the formulas and engineering explanations. Another great place to get information is Home Power Magazine. You can get the issues online or in print. Thanks for going solar!

Q: Single crystal solar panels and polycrystalline solar panels: monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.

Q: Can solar panels be used in areas with high levels of humidity?: Yes, solar panels can still be used in areas with high levels of humidity. While humidity can potentially impact the performance of solar panels, they are designed to withstand various environmental conditions. Modern solar panels are built with protective layers and are tested to ensure durability and efficiency in different climates, including high humidity areas. Additionally, regular maintenance and cleaning can help mitigate any potential effects of humidity on solar panel performance.

Q: What about sources for straight forward solar powered products? Excluding toys, garden frogs and outdoorpath lights I have found few useful items for the home. What I have found are solar panels for under $00 each, inverters, rechargeable indoor lights and a few camping/RV products that are interesting. It seems to me that these could help me start to wean the family off the power company. I can't afford to go cold turkey and cover my roof with solar panels and I don't think the HOA would allow me to even if I could. Is anyone using solar on a small scale?: I okorder Hope this helps.

Q: Can solar panels be used in areas with high levels of chemical pollutants?: Yes, solar panels can be used in areas with high levels of chemical pollutants. However, frequent maintenance and cleaning may be required to prevent the accumulation of pollutants on the panels, which could reduce their efficiency over time. Additionally, the presence of chemical pollutants in the air may have a negative impact on the overall performance and lifespan of the solar panels. Therefore, it is important to assess the specific conditions and potential risks before installing solar panels in such areas.

Q: If I wanted to put some solar panels on my roof, how many would i need and how many watts would they have to be to be able to power my whole house?: Actually even if you cover your whole roof with panels, you wont get enugh power to even run a tv, fan and light at the same time. Solar panels give out a very less power output.

Q: How do solar panels convert sunlight into electricity?: Solar panels convert sunlight into electricity through a process known as the photovoltaic effect. This involves the use of semiconducting materials, typically silicon, which absorb photons from sunlight. When the photons strike the solar panel, they transfer their energy to the electrons in the material, allowing them to break free from their atoms. This generates an electric current, which is then captured and harnessed by the solar panel to produce usable electricity.

Q: I made three 36 solar cell (3x6 .5V 3.5A) panel and had it hooked a up to an old car inverter. I was on line looking for a cheap grid tied inverter. I came across the Enphase micro inverter and was wondering if i could use one of those. Will it work?: It won't work for several reasons. ) Enphase needs 24V modules, you made 8V ones. The voltage is too low to turn it on. 2) Only UL listed (or similar lab) panels are allowed to be connected to your house electrical system. Even if you did get them to work with the Enphase, you won't be able to get the system inspected, there is no way it would be allowed to be turned on by the electrical inspector nor the electric company. 3) If you got by obstacles and 2, and you had an electrical fire in your house, it is highly likely your insurance company would not pay you for it, as you used non-UL panels. DIY panels are fine for little back yard projects, but when it comes to your home, buy real ones. The price has dropped so much in the last 2 years, it's not worth it to mess around.

Q: Can solar panels be installed on a stadium or sports arena?: Yes, solar panels can be installed on a stadium or sports arena. In fact, many stadiums around the world have already adopted solar panel systems to generate clean and renewable energy. These large roof areas provide ample space for solar installations, helping to offset energy consumption and reduce carbon emissions. Additionally, solar panels on stadiums can serve as a symbol of sustainability and inspire others to embrace renewable energy.

Q: Basically I need a custom solar panel created. I won't go into detail but the dimensions need to be around 4''x2.5'' and be as thin as possible.: okorder Other sources available on the first Link also. Wingman
