Problems solved by technology

There are several disadvantages in the above-mentioned technical solutions: ①The utilization rate of solar energy is not high because the tracking and concentrating technology is not used; ②The cooling liquid is used to cool the solar cells, so much heat cannot be obtained, and it is low-temperature heat energy, less than 100°C ;③ The battery components used are unconventional components, which need to be redesigned and assembled. The technology is complex and difficult to realize
