Weipai street lamp recruitment

Hello, everything is expensive now, and the cost of finished products is getting higher and higher. Solar street lamp, a 7-meter standard lamppost is about 650 yuan, and an 80-watt polysilicon solar panel is about 240 yuan. If single crystal silicon is used, it will cost about 40AH lithium iron phosphate battery 1000 yuan (local tyrants use this lithium battery, the average unit price of lithium battery1yuan ampere hour, the unit price of lithium iron phosphate is conservative, and 25 yuan ampere hour), lamps and lanterns 80 yuan. Domestic brands are doing better, such as jinhui lighting, Weifa License and Yongan Lighting. And hope to adopt them.
