The price of PV modules is decreasing rapidly. For crystalline cells, new ways of processing silicon and increased volume manufacture are driving down prices. Because of the decreasing prices, the rapid growth in the market for grid-connected PV is expected to continue even if government support is reduced.
The market will really take off when electricity from PV becomes cheaper than other grid sources. And PV is the easiest renewable electricity source to incorporate into buildings. The electricity is supplied at the point of use, thus avoiding the losses which occur in electricity distribution. It can be used at any scale – from less than a kWp on an individual home up to MWp scale systems on large public buildings - and is simple and reliable.
Because of this, it is a valuable way to raise awareness of electricity supply and use, and helps highlight the potential for renewable energy.
