PV Gap

Solar energy to electricity Transfor process?

We Answered:

The sunlight hits photovoltaic cells, and they generate electricity.

The cells are wired in series (like flashlight batteries) so the voltage adds up.

The direct current from the photovoltaic cells goes to a inverter, or device to change direct current to alternating current (a.c. like in your house).

The house either uses the excess electrcity generated or it is pushed back wards through the electricity meter back onto the utlity power lines for otthers to use it.

how do you change solar energy to electricity?

We Answered:

Well large scale(power plants) is solar thermal which basically uses the heat of the sun to super heat air, boil water and turn a turbine. Small scale like a calculator or satelite uses a photovoltaic cell to convert the energy. It works By using basically a metal plate keyed to a certain frequency to trap and use electromagnetic radiation(light) and emit electrons which are the base of the power. its called the photoelctric effect if you wanted to look it up for a little more depth.
