How does solar energy turn into the elctricity in your house?

i know that it comes from the sun and goes into a solar panel and the to a gerator but how does it turn into electricity?

Challenge question?

Modern solar panels are approximately 10% efficient. That is 10% of the energy in sunlight striking the panel is actually converted into useful electricity. During the day, approximately 2.5×10^27 photons of visible light strike a square kilometer of earth every second (1 photon of visible light has an energy of about 4×10^-19 joules).

The Watt is a unit of power. 1 Watt is equal to 1 Joule per second. A 100-Watt light bulb therefore requires 100 joules of energy per second to stay lit.

Based on this information how big a solar panel (in square meters) is required to provide 350 Watts of electric power on a typical day?

I got 35 square meters but its wrong. What do you get?

Solar panel connected to battery ??

im doin a science experiment and i have a battery that is 3.6 volts , does it matter wut voltage the solar panel that im connecting it to is . Does it need to match , be less or does voltage have no effect . If so wut does matter when choosing the type of solar panel to power a bettery?

Is a solar panel capable of producing more power than it takes to make one?

If you shine a lamp onto a solar panel…?

Essentially, would it power itself forever? I mean disregarding how you would start the cycle, is it possible for the light to power the panel, which brings the light?

Make sense?

washing machine does/t power up enough to run it. hear it try then cuts off.?

washing machine fills with water but when its supposed to start agitating it just hums then I hear a click that sounds like it comes from the instrument panel.

Where can i get 12 V 1000 mAh ( 10xAA)NiCd Battery Pack for solar power panel?
