Tell me in the order of solar pannels for a average home user? what sort of pannels i need for an average home, what should...
what sort of pannels i need for an average home, what should be the power production for that and from where on earth i can purchase..I need to install those contained by India........
Answers: A standard home uses about 3 to 6 kw-hr per morning. Depending on family size. On a full sunny daytime polycrystal solar cell can produce 1 kw / m^2 with the solar cell directly facing the sun. If the solar panals are fixed then it produces smaller amount. For a fixed solar panal on a clear day you can produce roughly 2 kw-hr of energy per m^2. You can find the optimum tilt angle base on your location on Earth at various solar company net sites. Therefore, the minimum number of solar panels is 20 meter square because the single produce about 0.2 w/m^2 at $615/m^2. That is going to cost you more or less $12500.00.
However you probably want to save some strength to batteries to hold energy at dark time. If you have the brass then I recommend NiMH because they hold a larger capacity. If you want to step cheap then used lead-acid battery. A standard car battary can hold 0.25 kw-hr. However, it is not a virtuous idea to fully drain lead-acid batterias becaust that reduce their useful enthusiasm time. Therefore, you will need 16 lead-acid battery. They cost about $55 respectively so the total is $880.00.
Now you need a power converter from 12 DC to 120 AC. They are simply about $220.00, plus a bunch of telecommunication and switchs $200. The total cost is about $13300.00.
There is too much to swot up about solar to answer it here. Read up on photovoltaic solar systems on the Internet, and by typing "Solar Panels" surrounded by the green search above on this page.
