Photovoltaic system, also known as solar photovoltaic system, is a technology that uses the photovoltaic effect of semiconductor interface to directly convert light energy into electrical energy.

Wood Cube's photovoltaic system maximizes the energy efficiency of the technology-integrated house. Therefore, a solar photovoltaic energy self-sufficiency system has been independently designed for selection.

This energy self-sufficiency system can basically meet the lighting and daily life of wooden houses.
