The solar energy power supply system is green and environment-friendly.
Solar energy is generated by hydrogen-helium fusion of hydrogen atoms inside the sun to release huge nuclear energy, and is the radiant energy from the sun. The vast majority of human energy needs comes directly or indirectly from the sun. The solar energy on earth is very huge, and about 40 minutes of solar energy on earth is enough for global human energy consumption for one year. Can be used for
In other words, solar energy is an inexhaustible energy source. And the solar energy is absolutely clean in power generation and does not cause public nuisance. So that solar power generation is praised as an ideal energy source.
The electric power is obtained from solar energy, and is realized by performing photoelectric conversion through a solar cell. The power generation principle of the power supply is completely different from that of other power supplies in the prior art, and the power supply has the following characteristics: no exhaustion danger exists; absolute clean (no pollution); not limited by resource distribution region; fourthly, the power can be generated nearby at the power utilization place; the energy quality is high; sixthly, the users are easy to accept from the feeling; and the time for obtaining energy is short. The disadvantages are as follows: the irradiated energy has small distribution density, namely, a huge area is occupied; secondly, the obtained energy is related to weather conditions of four seasons, day and night, cloudy and sunny and the like. However, as a new energy source, solar energy has a great advantage, so that it is regarded as important in all countries of the world.
Solar power generation is of two major types: one is solar power generation (also referred to as solar photovoltaic power generation), and the other is solar thermal power generation (also referred to as solar thermal power generation).
Solar photovoltaic power generation is a power generation method for directly converting solar energy into electric energy. The device comprises four forms of photovoltaic power generation, photochemical power generation, photoinduction power generation and photobiological power generation, wherein the photochemical power generation comprises an electrochemical photovoltaic cell, a photoelectrolysis cell and a photocatalysis cell.
Solar thermal power generation is to convert solar energy into heat energy and then convert the heat energy into electric energy, and has two conversion modes. One is to directly convert solar heat energy into electric energy, such as thermoelectric power generation of semiconductors or metal materials, thermoelectronic and thermionic power generation in vacuum devices, alkali metal thermoelectric conversion, magnetohydrodynamic power generation, and the like. Another way is to use solar thermal energy to drive a generator to generate electricity through a heat engine (e.g., a steam turbine), similar to conventional thermal power generation, except that the thermal energy comes not from fuel, but from solar energy.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
