[0002] At present, the development of solar power generation and heat utilization technology is relatively fast. In the field of solar heat utilization, solar low-temperature water heaters develop rapidly, but in the field of medium and high temperature, there are few applications due to high technical costs.

Solar power generation mainly includes solar photovoltaic power generation (solar cells) and solar thermal power generation, but the common problem is still the high cost of power generation

The raw material cost of the former crystalline silicon is difficult to break through. Whether the latter is concentrating with a dish reflector, a trough reflector or a tower planar reflector, the general idea is to increase the size of a single heat collector, and each reflector Using an independent tracking control system, the result is that the complex and bulky heat collection system is always difficult to reduce the cost of power generation for solar energy with a very low energy flux density

[0003] At present, the thermal units used in solar thermal power generation have low thermal efficiency due to the inability to achieve large capacity and high parameters. The thermal system using the Stirling cycle has higher power generation efficiency, but some technical problems such as the sealing of the internal gas working medium are still unresolved. It is better not to be widely used and the cost is very high

Solar high-power concentrator cells have high power generation efficiency, but the manufacturing process is complex and costly. Ordinary crystalline silicon cells can use low-power concentrators, but their power generation efficiency decreases with the increase of the concentration temperature. The cooling water system is used to cool the battery. poor, few applications

[0004] Regardless of solar tracking and concentrating, solar thermal power generation or solar cells, although each has continuous technological progress, the cost of solar power generation is decreasing year by year, but the overall feature is still high cost and high investment, which is far from the cost of ordinary electricity. Partial technological breakthroughs are difficult to significantly reduce the cost of solar power generation, and more effective overall solutions need to be explored
