Disadvantages of solar energy
(1) Dispersion: Although the total amount of solar radiation reaching the earth's surface is large, the energy flow density is very low. On average, near the Tropic of Cancer, when the weather is clear in summer, the irradiance of solar radiation is the highest at noon, and the average solar energy received in an area of 1 square meter perpendicular to the direction of sunlight is about 1,W; If it is averaged day and night throughout the year, it is only about 2W W. In winter, it is only about half, and in cloudy days, it is only about 1/5. This energy flow density is very low. Therefore, when using solar energy, in order to get a certain conversion power, a set of collection and conversion equipment with a considerable area is often needed, and the cost is high.
(2) Instability: Limited by natural conditions such as day and night, season, geographical latitude and altitude, and influenced by random factors such as sunny, cloudy, cloud and rain, the solar irradiance reaching a certain ground is both intermittent and extremely unstable, which makes it more difficult to apply solar energy on a large scale. In order to make solar energy a continuous and stable energy source, and finally become an alternative energy source that can compete with conventional energy sources, it is necessary to solve the problem of energy storage, that is, to store the solar radiation energy in sunny days as much as possible for use at night or in rainy days, but energy storage is also one of the weak links in solar energy utilization.
(3) Low efficiency and high cost: The development level of solar energy utilization is feasible in theory and mature in technology. However, some solar energy utilization devices, because of their low efficiency and high cost, now the utilization efficiency of the laboratory does not exceed 3%. Generally speaking, the economy can not compete with conventional energy sources. In the future, the further development of solar energy utilization is mainly restricted by economy.
(4) Pollution of solar panels: At present, solar panels have a certain life span, and generally they need to be replaced once every 3-5 years at most, but the replaced solar panels are very difficult to be decomposed by nature, thus causing considerable pollution.
that's all about the top ten brands of solar energy. I hope it will help you!
