As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and utility-scale solar power stations with hundreds of megawatts are being built. Solar PV is rapidly becoming an inexpensive, low-carbon technology to harness renewable energy from the Sun.
In their recent solar PV technology roadmap, the International Energy Agency included an LCOE range for utility scale solar of $80 to $190/MWh, with real costs in the range of $110 to $142 in Germany, the location of some of the cheapest solar in the world.
