Concentrator PV: harvesting more, spending less

Photovoltaics World: "CPV technology has clearly moved out of the lab and prototyping phase—becoming a reality with multi-megawatt installations underway
Today we are faced with dramatically increasing electricity demand globally presenting a critical need for clean, renewable energy. While the sun is the world’s most abundant renewable resource, today it is barely tapped as an energy source. The challenge has been in cost effective conversion of that sunlight to electricity. Historically, harvesting photons has been hindered by high costs compared with traditional energy."
