YSTEM
A system consisting of solar panels, modules, and related equipment (e.g., heat exchanger, pipes,
inverter, wiring, storage) that collects solar radiation and transfers it as heat to a carrier fluid for use in
hot water heating or space heating and cooling, and/or that collects solar energy and converts it into
electricity. As an accessory use, a solar energy collection system is designed to primarily meet on-site
demands (but may include transfer of excess electricity to an electric utility grid) and components are
typically mounted on the roof(s) of principal or accessory structures, but may be mounted on other parts
of structures, or on the ground.
