Why is the price of rural solar street lights decreasing year by year?

Street lights and solar panels. Batteries together, become solar street lights. It has now spread to the vast rural areas. I don't know if you have noticed that the price of solar street lights is decreasing year by year. In the past two years, solar street lights with a medium configuration can be sold for 1,200 yuan, and now solar street lights with the same configuration can only sell for more than 900 yuan, or even lower. what is the reason?
1. The number of solar street light manufacturers has sprung up like mushrooms after a rain

In the past few years, the country has vigorously developed new rural construction, and new rural road construction must use a large number of energy-saving and environmentally friendly solar street lights. Therefore, the market and sales volume of solar street lights produced by manufacturers are not bad, and the profits are considerable. Therefore, many assets are invested in the solar street light industry, resulting in an increasing number of manufacturers. With the increase of solar street light manufacturers, the industry competition has become more intense, and everyone has started a price war, so the price of solar street lights has dropped year by year. In addition, there are many bag companies and unscrupulous merchants who cut corners, set false standards and enter the market at extremely low prices to attract customers.

2. The price of various raw materials for the manufacture of solar street lights is reduced

1. The price of silicon wafers that make up solar panels has dropped by more than half due to market reasons.

2. The price of Q235 steel used to manufacture solar street light poles has dropped by one-third compared with the previous one, so the price of the produced street light poles has dropped.

3. The price of LED chips, shells and aluminum substrates of solar lamps has decreased, resulting in lower prices of solar lamp series.

4. Lower prices of lithium battery cells and solar street light controllers, resulting in lower prices of finished solar lithium batteries.
