Balance of system

The balance of system ( BOS ) is a component of a photovoltaic system other than the photovoltaic panels . [1] This includes wiring , switches, a mounting system , one or many solar inverters , a battery bank and battery charger .

Other optional components include, renewable energy credit revenue-grade meter, maximum power point tracker (MPPT), GPS solar tracker , Energy management software , solar concentrators, solar irradiance sensors, anemometer , or task-specific accessories designed to meet Specialized requirements for a system owner. In addition, CPV systems require optical lenses or mirrors and sometimes a cooling system.

In addition, ground-mounted, large photovoltaic power station require equipment and facilities, such as grid connections, office facilities, and concrete. [2] Land is sometimes included as part of the BOS as well.
