True Statement About Solar Power Systems

Which one of the following statements is TRUE?

Solar cells or PV release methane when using light to generate electricity. Solar power systems are often most productive during periods of peak energy demands. In the United States, the greatest potential for the use of solar energy is east of the Mississippi River. The manufacture of PV panels does not require the use of any fossil fuels.

The statement that is TRUE is:

Solar power systems are often most productive during periods of peak energy demands.

This is because solar power generation typically peaks during the day when energy demand is also high, especially during hot weather when air conditioning use increases.

The other statements are false:

• Solar cells do not release methane; they convert sunlight into electricity.
• The greatest potential for solar energy in the United States is generally considered to be in the western states, where there is more sunlight.
• The manufacture of photovoltaic (PV) panels does involve the use of fossil fuels, particularly in the extraction and processing of
