at present, with the growth of the population, human demand for energy is more and more big. Geothermal power, hydropower, wind power, fossil fuels, and so on are people explore energy generation. Do you know about solar power? You know five main part of the solar system? 1. Solar panels, Solar energy components, mainly divided into two categories, crystalline silicon and thin film components) Crystalline silicon components are divided into two categories, monocrystalline silicon and amorphous silicon; The selection of solar panels: first of all, do not recommend using membrane components. Why do you say that? From the point of market share, the market share of the membrane module is relatively low, so you don't need to know about it. Secondly, I want to talk about single crystal and polycrystalline module choice, because both have a large market share and mature technology. This two parts guarantee in 25 years power output of less than 80% of the initial power. The mandatory clauses in the contract. If not, please consider to change. 2. Photovoltaic stents ( Divided into fixed stents and tracking) ; The stent: for stent, usually choose fixed bracket, because although tracking stent has been mature, but in the later need maintenance costs, market share is relatively small. So it must be fixed bracket. Fixed bracket of the common market is hot dip galvanized C shape steel stents. Mounting bracket should pay attention to avoid the welding method. If due to factors such as room type bearing, must be conducted for welding antirust processing, be antirust processing through the regular inspection. The service life of the stent and parts service life is basically the same. 3. Inverter ( Including series inverter, miniature inverter and centralized inverter) ; Inverter choice: centralized inverter is not applicable to small distributed systems; There is too much waste in using the micro inverter. In general, choose group series inverter, series inverter in the same way about the market share. If you don't know the market share, you can attach it, look at what install user use brand, how often fail. No specific brand is recommended. 4. Cable; Pv cable is widely used in distributed systems. Compared with the ordinary cable, pv cable has different performance, such as high temperature resistance, ageing resistance, carrying capacity, bending, etc. In this system, the use of photovoltaic cable has nothing to do with DC. No need to worry about communication cable. Overall, this meets the requirement of the national grid. Otherwise, the state grid will not be for pre-acceptance. 5. Distribution box ( Junction box) Distribution box ( Mother's head) Choice: in general, the mother box according to the different installation capacity, with a different interface and power supply. The basic requirement of the power distribution ark small-scale distribution is not high. As long as there is independent of the reclosing, lightning arrester, circuit breaker and the breaker, requirement varies from place to place, and according to the local requirements. Industrial and commercial usually equipped with online quality detector. This is the five components of photovoltaic power generation system, each play a crucial role. Some resources are limited, some resources can be recycled, but we also need to each of us has the consciousness of saving resource in our daily life, walk the road of sustainable development, good care environment, protect the earth.
