Solar Power

Photovoltaic

Photovoltaic are best known as a method for generating electric power by using solar cells packaged in photovoltaic modules, often electrically connected in multiples as solar photovoltaic arrays to convert energy from the sun into electricity. To explain the photovoltaic solar panel more simply, photons from sunlight knock electrons into a higher state of energy, creating electricity. The term photovoltaic denotes the unbiased operating mode of a photodiode in which current through the device is entirely due to the transduced light energy. Virtually all photovoltaic devices are some type of photodiode.

Concentrator Photovoltaic Arrays (CPV)

Using optical lenses and mirrors we concentrate the sunlight onto a very small, highly efficient Multi-Junction solar cell. For example, under 500-sun concentration, 1 cm2 of solar cell area produces the same electricity as 500 cm2 would, without concentration. This is particularly significant when considering the inherent efficiency advantage of the Multi-Junction technology over Silicon solar cells the use of concentration, therefore, allows substitution of cost-effective materials such as lenses and mirrors for the more costly semiconductor PV cell material.
