The application of solar thermal power generation technology still faces some technical difficulties and bottlenecks, including the following aspects:

(1) Low photothermal conversion efficiency: The current conversion efficiency of photothermal power generation technology is relatively low, and more efficient photothermal conversion technology is needed to improve conversion efficiency.

(2) Large heat loss: In the process of solar thermal power generation, there is a certain loss in the transmission and storage of thermal energy, and it is necessary to improve the transmission and storage technology of thermal energy to reduce heat loss.

(3) High equipment cost: The construction and maintenance costs of solar thermal power generation equipment are high, and it is necessary to reduce equipment costs and improve equipment lifespan.

(4) Weather condition limitations: Solar thermal power generation technology requires sufficient sunlight exposure, and weather conditions have a significant impact on it. Therefore, it is necessary to develop solar thermal power generation technologies that can adapt to different weather conditions.

(5) Immature energy storage technology: Currently, the energy storage technology for solar thermal power generation is not yet mature, and more efficient energy storage technologies need to be developed to make solar thermal power generation technology more sustainable.

In response to these technical difficulties and bottlenecks, it is necessary to strengthen research and technological innovation, improve the conversion efficiency and energy storage efficiency of solar thermal power generation technology, reduce equipment costs, and promote the development and application of solar thermal power generation technology.
