Second era cells are slim movie solar cells, that come with amorphous silicon, CdTe and CIGS cells and are commercially substantial in utility-scale photovoltaic power stations, setting up built-in photovoltaics or in small stand-by itself power system.
Grid-connected systems combine solar arrays with public utility power grids in two methods. A person-way systems are utilized by utilities to complement power grids during midday peak utilization.
