The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
I personally think that the use of solar energy is not very environmentally friendly, because the market is currently the main products of solar energy use monocrystalline silicon or polysilicon, thin film with very little. We all know that silicon is a heavy metal, pollute the environment and can not be removed, because the film component cheap but the conversion rate is low, can only be used in small products, such as computer, application of technology products such as lamps, although the silicon conversion rate is high but the price is expensive, so the application of products currently on the market to see the most use of polysilicon, 25 years after this type of product, service life expires, how to deal with??? Is a problem, so I still want to improve the conversion rate of thin film components.
3, placed the location of stress, angle, sunlight time, the surrounding environment is not easy to miscellaneous. Although the outside component is made of toughened glass, but also can not afford to toss the firecrackers. And aroundIf there is debris, easy to cause the "island effect" causes the component to burn oh.
2, slow heating, temperature can not be stored, no storage function,Because now the market does not rely on solar energy storage battery, so no matter how good the sun, onlyTo provide the energy required for the day, the next day must be used on the rainy day electricity heatingWater heater fee
You mean the solar water heaterSimply say:Benefits: power saving, safety,Disadvantages: 1, temperature affected by the weather,Because solar water heaters rely mainly on the absorption of sunlight, the light energy into electricity for heating waterSo the intensity of the sun directly affects whether you need to use electricity heating
