Hello everyone, solar power generation is also called photovoltaic power generation. The current penetration rate is much higher than it was 15 years ago! Take the cost of tens of dollars per watt 15 years ago, let the average Chinese family and business I can't afford it directly~~ However, after the National Development and Reform Commission started the kWh subsidy, the cost of photovoltaics plummeted, which also allowed China's photovoltaic market to start a blowout growth. At the same time, photovoltaic power generation has also developed into: large-scale centralized ground power stations, small-scale distributed power stations and smaller-scale household distributed power stations. Of course, the one we are most familiar with is the household distributed power station. Of course, many families who have not installed here are also beginning to move around! But faced with a wide variety of battery panel brands and different types of battery panels, how should we choose? The following editor will give you a popular science: First of all, let's first understand that the mainstream solar panels on the market are divided into: 1. Monocrystalline solar panels. 2. Polycrystalline solar panels. 3. Thin-film solar panels. The difference between them is: 1. The photoelectric conversion efficiency of monocrystalline silicon monocrystalline silicon solar cells is about 18%, and the highest is 24%, which is the highest photoelectric conversion efficiency among all types of solar cells, but the production cost is very high. Large, because monocrystalline silicon is generally packaged with tempered glass and waterproof resin, it is durable and has a service life of up to 25 years. 2. The production process of polycrystalline silicon polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells is much lower, and the photoelectric conversion efficiency is about 16%. In terms of production cost, it is cheaper than monocrystalline silicon solar cells, the material is simple to manufacture, power consumption is saved, and the total production cost is lower, so it has been greatly developed. In terms of cost performance, monocrystalline silicon solar cells are slightly better. 3. Amorphous silicon amorphous silicon solar cell is a new type of thin-film solar cell that appeared in 1976. It is completely different from the production method of monocrystalline silicon and polycrystalline silicon solar cells. The process is greatly simplified, the consumption of silicon materials is very small, and the power consumption is more. Low, its main advantage is that it can generate electricity even in low light conditions. However, the main problem of amorphous silicon solar cells is that the photoelectric conversion efficiency is low, the international advanced level is about 10%, and it is not stable enough. With the extension of time, its conversion efficiency declines. We mainly produce and sell outdoor road, square, station, wharf, courtyard and indoor industrial and mining lighting fixtures. Varieties are:
