What is more effiecient? a solar thermal system or a solar photovolaic system?
d.c. wattage
Probably because a solar panel can produce electricity for many years.
The solar panels produce electricity by the sunlight.
That depends on the panel.
It wouldn't produce any electricity.
500 volts!!
Actually you can. A photovoltaic cell (a.k.a. solar panel) does precisely that.
a solar panel
The only thing that lies with in the casing of the solar panels are the photovoltic cells which are used to produce the electricity.
The amount of power generated by a solar tracker depends upon the type of tracking system used. A fixed tracker will produce less electricity than an active tracker because a fixed tracker only creates maximum energy when the sun is directly in line with the panel. Active trackers follow the sun and produce consistent electricity as the sun moves through the sky. The size of the panel also affects how much power is produced, as large solar installations will obviously generate more electricity than a small panel on a house. Solar panels usually have a number listed on the back that shows the power output you can expect in ideal conditions, but this is not usually what is actually produced. Generally, a standard solar panel on a house can produce about 200 watts of power each day.
(Another contributor wrote:)Light has its own energy and when it is conducted by a material the energy turns into electrons which are collected and made into direct current electricity (DC). When sunlight fall on a solar panel (pv cells) the electrons get excited and start flowing and the electron flow is nothing but electricity. Thus a solar panel produces electricity.
u multiply your voltage times max current (amps) and this gives u max wattage.
