Grid Parity

Grid Parity is where electricity produced by means of renewable energy sources as food plants has the same price as energy produced through conventional energy sources i.e. fossil sources.
The term Grid Parity tends to refer to the parity between the cost of producing electricity from photovoltaic system and the cost of purchasing power from the grid.

Analysts estimate that within a decade for solar energy will be cheaper than coal and gas in almost all regions of the world.
