Photovoltaic Grid Parity in Spain

Photovoltaic (PV) grid parity can be considered as the point at which PV electricity is generated at the same price as the electricity of the electrical grid is generated (which is a mix of different generation sources) or as the point at which PV electricity becomes cost-competitive with conventional grid-supplied electricity. Depending on which definition of grid parity is used, the year when it is reached may vary. A study of grid parity, considering both definitions, has been carried out with regard to Spain.
