Solar energy is renewable source of energy and more intensive non-polluting energy, the sale of photovoltaic solar power in the stem .The solar panel is reliability and its sale is increased by 40% a year for 10 years. Solar energy had a second boost during energy and pollution crisis. The solar panel station do not work effectively once in temperature exceeds 45 C. solar panel efficiency deceases with in increase in temperature above 40 C. Here we are using Peltier plate to increase the life span of the solar panel.to avoid the negative temperature coefficient of solar panel. In this project we are able to known its temperature and output voltage in wi-fi devices.
Photons below a threshold wavelength have enough energy to break an electron-hole bond in semiconductor crystal, which in turn can drive a current in a circuit .The solar radiation consist of photons at a range of wavelength and corresponding energies. Photon with wavelength above the threshold are converted into heat in the PV cells.
This waste heat must be dissipated efficiently high cell temperature , which have an adverse effect on the electrical performance of the cells. The cells are the most expensive part of a photovoltaic system.
When photovoltaic cells are used under concentrated illumination , they experience a high heat load because the photons not converted to electricity are dissipated in the cells as heat.so to make it successful photovoltaic concentrator is a cooling system which can efficiently remove the dissipated heat while keeping the cells at the desired temperature. Peltier plates to maintain the solar well as we can monitor it online.
