The Balance of System components of a photovoltaic system, can be understood as balancing the power-generating subsystem of the solar array (left side) with the power-using side of the AC-household devices and the utility grid (right side).

The balance of system or BOS encompasses all components 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. For ground-mount systems, land is sometimes included as part of the BOS as well.

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.
