The Complete Solar Rooftop System

A solar grid-tie system, also known as photovoltaic, or “PV”, uses roof-mounted or building-integrated solar panels to collect energy from the sun and convert it into usable electricity. A system installed on a grid-connected building can supply a portion of the power needed to run the site. During the day, electricity generated by the solar power system is fed into the building, offsetting the amount of power being drawn from the grid. Any excess power is fed back to the power utility to be used by someone else, resulting in a power credit.
