If the lighting is normal, it may be a configuration problem or other details. You can consult the technicians of Henan Huangchuan Limin Technology. My street lights are often repaired here. The technology is very good and powerful. During the last batches of street lights, there were always problems when installing other people's street lights. Now the installed street lights are all installed by Henan Limin Technology, and there are basically no problems.
Solar cells
Material requirements: resistant to ultraviolet rays and light transmission does not decrease. Tempered glass components can withstand the impact of an ice ball with a diameter of 25 mm at a speed of 23 meters/second.
The performance requirements of EVA film for installation after curing: transmittance above 90%; degree of crosslinking greater than 65-85%; peel strength (N/cm), verre/film greater than 30; TPT/adhesive film is greater than 15; temperature resistance: high temperature 85℃, low temperature -40℃; the back of the solar cell is resistant to aging, corrosion, ultraviolet rays, airtightness, etc.
