Researchers have developed twice residential solar panels more efficient

Currently used in residential and industrial application of the challenges facing solar panels convert sunlight into electricity is inefficient. The average conversion efficiency in the 17th - 19%. At the ecole polytechnique federale in lausanne ( EPFL） Spin-off of a company called Insolight researchers created new residential solar panels, the efficiency is almost twice the normal panels. According to the independent laboratory tests, the new type conversion efficiency of solar panels can be up to 29%.

the solar panels used a patent of the optical system, the sun on a tiny photovoltaic cells are normally used for satellite. Satellite using solar panels are usually very expensive, in order to reduce costs, the team developed a protection glass, the glass, optical lenses can be placed will sunlight concentration rate increase to more than 100 times, channeling the light from the sun to the surface of the high performance battery is very small.

the design means that the new solar cell covers an area of less than solar panel surface area 0. 5%. Move the solar cell level to allow the mechanism of a few millimeters panel follow the sun in the day. Due to the efficient Insolight design panel is very small, they can be laid at the top of the traditional solar panels, in order to improve the solar energy production. The hybrid method is especially effective in cloudy weather, for even if under the diffuse light can also generate electricity. The size and shape of the new panels with existing solar panels is the same, the same installation. Designers say, in a sunny area, this technology can cut the household energy bills by 30%, using the technology of the first commercial product is expected to launch in 2022.

the team said that their panels have been tested in all weather conditions. Tests show that in heat waves, storms and winter weather, panel has been working, without any problems. Solar energy research institute (Madrid university of technology IES- 芬欧蓝) In the test verified the conversion efficiency of solar panels up to 29%.
