Concentrated Photovoltaics - think beyond the fossil fuel age:

Circadian Solar offers turnkey solar systems based on Concentrated Photovoltaics, the technology with the world's highest efficiency and energy yield, optimised for Sunbelt regions such as North Africa or the Middle East.

Due to their much lower temperature coefficient, Circadian's Concentrated Photovoltaic Systems provide significantly greater energy yields in high temperature environments than silicon solar cells used in traditional photovoltaic installations.

Don't worry about the cost of electricity from Circadian's CPV system: the sun doesn't send a bill!
