Photovoltaic power generation systems are primarily made up of two components: PV modules, which convert solar energy into electrical energy, and a PV inverter, which converts the power produced by the modules into a form that can be used in the home.

Photovoltaic system performance depends on the performance of these two components. Mitsubishi Electric has developed both components in-house. Our PV module offers industry-class performance (for a polycrystalline silicon-based, domestic mass-produced module) and our PV inverter provides the best conversion efficiency in the industry (as of June 2008), for a system that generates robust power.
