How Much Power Does a Solar Panel Generate? | eHow.com - 0 views

  •  
    "Solar panels produce electric power according to their size, efficiency and how much sunlight they receive. For homeowners and small businesses, roof-mounted panels are a typical option. Solar panels rated at 100 to 200 watts cover about 10 square feet (1 square meter). The power you get from a 100-watt solar panel depends on how much sunlight it receives, and on a daily basis the total power is much less than the rated wattage"

The Energy Story - Chapter 15: Solar Energy - 1 views

  • When sunlight strikes the solar cell, electrons (red circles) are knocked loose. They move toward the treated front surface (dark blue color). An electron imbalance is created between the front and back. When the two surfaces are joined by a connector, like a wire, a current of electricity occurs between the negative and positive sides. These individual solar cells are arranged together in a PV module and the modules are grouped together in an array. Some of the arrays are set on special tracking devices to follow sunlight all day long.
