Do Solar Panels Use Mirrors

Concentrated solar technology systems use mirrors or lenses with tracking systems to focus a large area of sunlight onto a small area.

Do solar panels use mirrors.

For a cooker that is used for perhaps half an hour or so this is no problem. See article heliostat for more information on solar mirrors used for terrestrial energy. Concentrating solar collectors use mirrors and lenses to con centrate and focus sunlight onto a thermal receiver similar to a boiler tube. The concentrated light is then used as heat or as a heat source for a conventional power plant solar thermoelectricity.

Your can search for cpv or concentrating photo voltaics. The receiver absorbs and converts sun light into heat. Focussing mirrors however need to be directly exactly toward the sun to be of use. Normally solar panels are.

Cpv is not yet competitive in price with standard flat solar panels and it has the disadvantage that it requires direct sunlight. This may be a planar mirror or parabolic arrays of solar mirrors used to achieve a substantially concentrated reflection factor for solar energy systems. With cpv the sunlight shines directly onto mirrors or lenses which follow the sun and concentrate the light onto the solar cells. You can use more mirrors to reflect more light onto the solar panel and increase it s power further but on a sunny summers day the extra light can build up a lot of heat that may damage the panel.

Using cgi for solar simulations such booster reflectors also known as mirrors or planar concentrators are not widely used because of concerns about warranties. In july i had my 1 5w panel running at double its rated power for twenty minutes it got so hot you couldn t touch it. A solar mirror contains a substrate with a reflective layer for reflecting the solar energy and in most cases an interference layer. To use them on a solar photovoltaic array would require the user to constantly rotate the array requiring a sun tracker and considerable mechanical overhead.

This is probably one of the cheapest and easiest ways to boost the power of a small solar panel but this method does have some limitations.
