Back contact

Type of cell where the contacts are not deposed on the active surface of the cells, but integrated at the back of the module. This method presents two advantages: the aspect of the cells is uniform, which facilitates the aesthetic integration of the modules, and the absence of metallic grids augments the yield of the cell.

Balance of system (BOS)

The balance of system is the whole of the electric equipment other than PV modules: cables, switches, inverters, control and measurement systems, batteries and module fastening systems.

BiPV (Building Integrated Photovoltaics)

Acronym of "Building Integrated Photovoltaics", it refers to those photovoltaic elements that are an integral part of a building while they produce also electric energy at the same time.
