A Little Solar, or a Lot?
There are three different variables that can determine how large a solar system homeowners should choose, says Neville Williams, founder of Standard Solar, which sells and installs solar home systems in the Mid-Atlantic: “The size of their roof, the size of their pocketbook, and the size of their electric bill.”

He encourages people with smaller roofs or pocketbooks not to feel they have to generate all of their power with a solar system—they can purchase only two or three kilowatts of solar generating capacity. Even a small solar system lowers your energy bill and your carbon footprint.

“Almost everybody can afford some level of solar power,” says Williams. Also, be sure to take all the smart energy efficiency steps first, so your solar system can better cover your now much-lower energy needs.
