Concentrating Light On Solar Panels

One of the ways to increase the output from the photovoltaic systems is to supply concentrated light onto the pv cells.

Concentrating light on solar panels. Based on the principal that a solar cell receiving more light energy will produce more electricity concentrating photovoltaic solar panels simply involve a method usually using a lens or mirrors to concentrate more sunlight onto a photovoltaic cell. Swiss company insolight has created the most efficient concentrating photovoltaic solar panels cpv a technology that uses lenses to concentrate light onto small solar panels underneath to date. In concentrating photovoltaics cpv a large area of sunlight is focused onto the solar cell with the help of an optical device. Concentrated solar power also known as concentrating solar power or concentrating solar thermal power works in a similar way conceptually.

Concentrator photovoltaics cpv also known as concentration photovoltaics is a photovoltaic technology that generates electricity from sunlight. In addition cpv systems often use solar trackers and sometimes a cooling system to further increase their efficiency. Unlike conventional photovoltaic systems it uses lenses or curved mirrors to focus sunlight onto small highly efficient multi junction mj solar cells. Heliostats are tracking mirrors that reflect solar energy onto a fixed target.

This can be done by using optical light collectors such as lenses or mirrors. There are three main systems in use. Csp technology utilizes focused sunlight. Concentrated solar technology systems use mirrors or lenses with tracking systems to focus a large area of sunlight onto a small area.

After two years of research its created a cpv panel that achieved 29 efficiency verified by the universidad politécnica de madrid. The concentrated light is then used as heat or as a heat source for a conventional power plant solar thermoelectricity. By concentrating sunlight onto a small area this technology has three competitive advantages. Concentrating solar collectors use shaped mirrors or lens to provide higher temperatures that flat plate collectors.

At a csp installation mirrors reflect the sun to a focal point. Light concentration while photo voltaic panels are the most appropriate method for capturing light energy in domestic solar power installations for larger scale systems light is usually concentrated to produce heat which in turn is used to generate electricity. Concentrating solar power csp technologies use mirrors to concentrate focus the sun s light energy and convert it into heat to create steam to drive a turbine that generates electrical power. This page concentrates on providing links information and plans for build it yourself concentrating collectors and heliostats.

Csp technology produces electricity by concentrating and harnessing solar thermal energy using mirrors. The pv systems that use concentrated light are called concentrating photovoltaics cpv.
