Solar panels light conversion rate is not more than 20%. In order to improve the utilization rate of solar energy and reduce the development of new energy losses, we discuss the system and to improve the spotlight to light intensity to improve the light energy utilization, and at the same time through thermoelectric conversion principle to reduce the energy loss. Solar panels in electronic again through the P-N structure, if in a semiconductor, through the resistance will be very big, loss is very big. So in panels on the metal nets, not only ensure the light through electronic in metal and ensure the flow, the surface is very slick solar panels, the reflectivity of light is very high, so want to be in the panels with less reflective surface of material in order to improve the light energy utilization ratio. Because light panels will heat effects panels wi...
