BP Solar, the world leader in solar electric systems, provides everything you need in a single package. And trained
technicians from your BP Solar dealer can install the whole system in about a day, without disrupting your home or
current electrical wiring. The BP Solar Electric Systems use “photovoltaics” or “PV” to convert sunshine directly into
electricity. The power feeds into your home’s existing electrical circuits energizing lights and appliances. Any extra
power flows out to the power grid, actually spinning your utility meter backwards! For more information or the name
of a dealer near you, just call one of our trusted partners listed below.
