What is the meaning of solar energy
Solar energy is a kind of renewable energy, which is a kind of renewable energy. Solar energy is a source of energy, such as wind energy, chemical energy, water potential, etc..The solar energy conversion device to convert solar radiation into heat energy use is the use of solar thermal technology, using thermal power known as solar thermal power generation, also belongs to the technical field; through the conversion device to convert solar radiation into electricity use is solar power technology, photoelectric conversion device is usually photoelectric conversion principle of the photovoltaic effect of semiconductor devices, also known as solar photovoltaic technology.
Five, photovoltaic power generation is a static operation, no moving parts, long life, no need or very little maintenance.Six, photovoltaic system modular, can be installed in the vicinity of the power consumption of the place, far away from the power grid area, can reduce transmission and distribution costs, increase the reliability of power supply facilities.
Solar energy is a kind of green renewable energy that converts sunlight into electricity. Compared with other conventional energy sources, it has the following characteristics.A solar energy inexhaustible, inexhaustible. It is estimated that the projected solar energy into the earth in one year, the energy equivalent to 137 trillion tons of standard coal produced by the heat, about a year in the world by the use of a variety of energy generated by the energy of twenty thousand times
Three, solar energy resources all over the world, can be scattered, regional exploitation. About 2/3 of our country can make better use of solar energy resources.Four, photovoltaic power generation is intermittent, there is sunshine when the power generation, and the proportion of power generation is proportional to the intensity of the sun
