Your Questions About Photovoltaic Solar Panels Efficiency

Mark asks…

I have my sources and my bibliography cards, even a preliminary theses
“Solar panels are the next step in energy efficiency in the home”
Im doing my paper on photovoltaic and solar panels basically but now i have to write and outline and im wondering what questions i should answer because Research papers are a why question

Chris asks…

Solar energy reaching the earth is about 1350 W/m^2 outside the earth’s atmosphere, and 950 W/m^2 on earth’s surface normal to the sun on a clear day. Someone is marketing 2 m x 3 m photovoltaic cell panels with the claim that a single panel can meet the electricity needs of a house. How do you evaluate this claim? Photovoltaic cells have a conversion efficiency of about 15 percent.
