In the field of new energy, it is widely recognized that solar power generation has the highest technological content and the most promising development prospects. There are two basic ways of solar power generation: solar thermal power generation and solar photovoltaic power generation.
01 Solar thermal power generation
Devices that convert absorbed solar radiation heat into electrical energy can be divided into two categories:
One type is direct conversion of solar thermal power, such as thermoelectric power generation, which currently has very low power and some are still in the principle testing stage;
Another type is solar thermal power generation, which uses solar thermal energy to drive a generator through a heat engine to generate electricity. Its basic components include a heat collection device, energy storage system, heat engine, and generator.
02 Solar photovoltaic power generation
The utilization method of directly converting solar energy into electrical energy without undergoing thermal processes. It can be divided into photovoltaic power generation, photoinduced power generation, photochemical power generation, and photobiological power generation.
The current application of photovoltaic power generation is to directly convert the photovoltaic effect generated by the light shining on the solar cell into direct current energy output. It generally consists of solar cell arrays and brackets, batteries, controllers, inverters, and other components.
Its disadvantage: intermittent. Affected by climatic conditions; Low energy density; High initial investment. So far, more than 100 countries have participated in the development and application of solar photovoltaic cells.
In recent years, production has rapidly increased and production costs have begun to decline. At present, photovoltaic power generation is mainly used in three aspects: providing power for non electric field fusion; Solar powered daily electronic products. Such as various solar chargers, solar lamps, etc; Grid connected power generation.
