light-emitting diodes, solar street lamp, jschindo。 com) Mainly used for electric power facilities in daily life is not convenient place. Because it provides energy for the sun lighting, so compared with the use of electric lights, it's very environmental protection, though it has; As ever, an inexhaustible; But it also has its own advantages, disadvantages, let's take a look at it. 1. Dispersion: although the amount of solar radiation reaching the earth's surface is very big, but the energy flow density is very low. Using solar energy, in order to obtain certain switching power, often need a large area of collection and conversion equipment. 2. Instability, such as day and night, season, geographical latitude, altitude, the limitation of natural conditions, as well as sunny, cloudy, rain, such as the influence of random factors, has reached a certain ground the solar irradiance is both intermittent, and unstable, making it harder for the mass of solar energy application. In order to make solar steady energy, and eventually become can compete with conventional energy alternatives, it is necessary to solve the problem of energy storage, the storage of solar energy as much as possible in sunny day, in preparation for the night or rainy day, but the energy storage is one of the solar energy utilization of weak links. 3. Low efficiency and high cost: the development of solar energy utilization level is feasible in theory, is technically mature. However, due to some device of low efficiency and high cost of solar energy utilization, in general, the economy can't compete with conventional energy. Quite a long period of time in the future, the further development of solar energy utilization is mainly restricted by the economy.
