We all know that solar photovoltaic (PV) technology is too expensive. Although technological advancements and economies of scale in manufacturing have lowered the cost of PV dramatically over the past decade, PV-generated electricity today is more expensive than power produced from conventional generators fueled with coal or natural gas. Many commentators suggest that the Holy Grail for solar is Grid Parity; once achieved, the world will be saved and fortunes will be made. Grid Parity is defined as the point when PV-generated electricity becomes competitive with the retail rate of grid power.
