Concentrated Solar PV systems employ lenses or mirrors to focus solar energy onto a photovoltaic module, panel or array, thus increasing power output.
The technology is currently in the early stage of development and faces challenges in identifying solar PV cells that can cope with the extremely high temperatures that result from concentrating the sun's energy.
However, a number of firms believe the approach could significantly increase conversion rates for solar energy systems, reducing the cost per watt in the process.
