Solar Panel Fresnel Lens

A solar concentrator diy can seem like the easiest thing in the world if someone else is doing the hard work.

Solar panel fresnel lens.

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. Solar arrays uses fresnel condenser lens with following benefits. 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. Fresnel lenses may in fact be regarded as a series of prisms are arranged in a ring wherein the relatively sharp edge and the center of the convex surface is relatively smooth.

It is pioneering the use of concentrating photovoltaic modules in which a fresnel lens focuses sunlight onto a small but high efficiency up to 38 solar cell known as a triple junction cell. Ultimately the cost of solar cell is several times lower than normal capacity which provides maximum benefits to the user. 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.
