Comparison of Solar Thermal and Solar Photovoltaic

Solar thermal is the heat energy radiated by the sun.

In addition to solar water heaters, solar light and heat utilization includes solar houses, solar stoves, solar greenhouses, solar drying systems, and solar soil disinfection and sterilization technologies.

Solar thermal power generation is an important aspect of solar thermal utilization. This technology uses a collector to concentrate solar radiant heat to heat water to generate steam, and then generate electricity through steam turbines and generators. According to different heat collection methods, it is divided into high temperature power generation and low temperature power generation.

If solar energy is used to solve the energy consumption of hot water, heating, air conditioning and lighting in buildings in an all-round way, this will be the most ideal solution. The integrated research and implementation of solar energy and buildings (including high-rise buildings) is an important direction for the development and utilization of solar energy in the future. It is also the foundation for the growth of the entire solar energy industry. Although there is no substantial progress in this area, because of the demand, with the efforts of the whole world, I believe that there will be a breakthrough in the near future.

Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It has two modes of independent operation and grid-connected operation. Independently operating photovoltaic power generation systems need batteries as energy storage devices, which are mainly used in remote areas without power grids and scattered populations. The overall system cost is very high; in areas with public power grids, the photovoltaic power generation system is connected to the grid and runs in parallel. The omission of batteries can not only greatly reduce the cost, but also has higher power generation efficiency and better environmental performance.
