What is a solar photovoltaic system
Photovoltaic is a kind of solar energy. Solar energy is now divided into two categories, one is the use of photovoltaic effect, that is, the effect of sunlight on the photovoltaic cells to generate electricity. Another is the effect of light and heat, that is, the principle of light gathering, the heat of the sun together, and the use of heat. If there is anything you can not understand.
To be exact, the use of solar energy is divided into three aspects of light and heat, photoelectric, photochemical, popular, that is, the use of solar energy to generate heat, generate electricity, produce chemical reactions.The easiest, most used, the most mature, is light and heat, the most common solar water heaters, of course, there are more high-end solar collectors and other applications;
Solar power, that is, photovoltaic, dubbed the new energy, but the current method of silicon, solar power generation, there are complex process, high cost bottlenecks.As for the use of solar energy for chemical reactions, the application is relatively small, only in some cutting-edge technology.
