Yes, and since your home’s air-conditioner will consume a large amount of electricity for every hour the compressor runs, a solar photovoltaic system can make that required electricity all day while the sun is shining. And one of the great side benefits of a solar system is your air-conditioner will likely not run as often nor for as long as it used to, because your attic will not get as hot during the day once solar panels are on the roof. That is because with a photovoltaic array on your roof the sun’s rays shin all day on the solar panels and less on your roof, thus reducing some of the heating effect in your attic. If your attic stays a bit cooler than your living space will not absorb as much heat from above the ceiling and your air conditioner will not have to work as hard to cool your home. So you win both in keeping your home cooler from lower solar radiation heat gain, plus making free energy from the sun’s rays striking your solar photovoltaic system.
