Solar Panel Fresnel Lens

Can even harvest energy from moonlight.

Solar panel fresnel lens.

A guy who calls himself grant thompson used a fresnel lens from a dismantled old toshiba projection tv and shows the world on youtube how his diy solar concentrator can scorch nearly anything from pennies and concrete to eggs. By concentrating solar power onto solar cells they can increase the amount of sun striking the solar cell and allow a relatively small amount of silicon photovoltaic pv material to be used in large solar panels. Ultimately the cost of solar cell is several times lower than normal capacity which provides maximum benefits to the user. Solar arrays uses fresnel condenser lens with following benefits.

Solar concentrator fresnel lenses were originally developed for concentrating photovoltaic cpv application. I use a large fresnel lens to test the effect of concentrated sunlight on a solar cell. The cutting edge design of fresnel lens and solar panels generates superior amount of electricity with customized lens size and incidence angle. A fresnel lens is a lens with multiple refracting planes designed to improve the concentration of light coming from many different angles onto a single point or line.

We managed to get 1 volt out of a solar panel at 2am. When placed in the sun the fresnel lens will act as a giant magnifying glass concentrating sunlight to a small area. These lenses are also used as a solar energy concentrator for solar furnaces. Over the years dan rojas has modified optical lenses to maximize the solar throughput increasing thermal concentration exceeding 3233 degrees fahrenheit.

To keep the solar cell cool i immerse it in mineral oil. This video was shot using concentrated moonlight only.
