This is a project to provide solar green lighting for rural roads and people’s leisure parks. The solar street lights use 2 pcs 100W solar panels, 80ah12.8V lithium iron phosphate batteries, and 60W solar street lights. The street lights are set by parameters, the first 6 100% brightness for the first hour, and 70% brightness for the next 6 hours, which can not only save power, but also reduce the brightness without affecting the sleep of residents. The picture is a 70% brightness photo.
