Fresnel Lens And Solar Panel

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.

Fresnel lens and solar panel.

Solar power concentrated photovoltaic systems. Such a lens can focus light on a small spot but does not produce a sharp image. A solar concentrator diy can seem like the easiest thing in the world if someone else is doing the hard work. 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.

A non imaging spot fresnel lens uses ring shaped segments with cross sections that are straight lines rather than circular arcs. These lenses have application in solar power such as focusing sunlight on a solar panel. The students pulse pasteurization using a lens and solar energy method uses a fresnel lens which is essentially a large magnifying glass but thinner and lighter in weight and made of acrylic and sunlight to pasteurize water.
