NREL’s Consumer’s Guide asks you.
Are you thinking about buying a solar electric system for your home or business?
If so, this booklet provides some basic information that can help you.
Solar electric systems, which are also called photovoltaic or PV systems,
are reliable and pollution-free. They make use of a renewable source of energy—
the sun. And PV systems for homes and businesses are becoming more
affordable all the time.
PV works best in an energy-efficient building. So, adding insulation and energy-
efficient lighting, appliances, and windows is a good idea, to reduce your
home’s overall electricity use before you install a PV system.
To make PV systems even more affordable, several states offer financial incentives
through solar rebates and other programs. Some utilities have net metering
programs, which further enhance the economics of PV. Net metering
means that when your PV system generates more power than you need, the
excess goes to the utility grid and the meter runs backward. This allows you
to receive full retail value for the power that your PV system generates.
This booklet can guide you through the process of buying a solar electric system.
It is not a technical guide to designing or installing a system—for that
information, we recommend consulting an experienced PV system designer
or supplier.
A PV system can be a substantial investment. As with any investment, careful
planning will help you make the right decisions for your home or business.
