Description

technical field [0001] The invention relates to the field of solar power generation, and more specifically, relates to an integrated power generation system of solar double concentrating photovoltaic and photothermal. Background technique [0002] With the consumption of fossil energy and the aggravation of environmental pollution, energy problems are becoming more and more prominent. As a clean and pollution-free green energy, the effective development and utilization of solar energy has become the top priority for realizing sustainable energy development. Among the effective utilization of solar energy, solar power generation technology is one of the fastest growing and most dynamic research fields in recent years. [0003] However, the dispersion of solar energy has become an important obstacle to the utilization of solar energy; the large-scale application of solar power generation technology is also hindered because of the expensive solar cell materials and cumbersome m...
