Features of the 600×600 Solar-Powered Speed Limit 20 Sign:
1. The 600×600 Solar-Powered Speed Limit 20 Sign is powered by monocrystalline silicon solar cells, which are made from high-purity monocrystalline silicon ingots. Compared to polycrystalline silicon, they offer higher photovoltaic conversion efficiency and better charging performance, eliminating the need for a power grid.
2. The 600×600 Solar-Powered Speed Limit 20 Sign features an inlaid encapsulation design with a custom-molded aluminum profile frame, ensuring a secure assembly. The light housing uses a fully waterproof design, enabling 24-hour, all-weather operation.
3. The 600×600 Solar-Powered Speed Limit 20 Sign uses ultra-bright Taiwanese Epistar LED chips, featuring eye-catching and vivid colors. It offers excellent visibility both day and night, ensuring greater safety for drivers on the road.
4. The 600×600 Solar-Powered Speed Limit 20 Sign uses 3M reflective film to produce a strong reflective effect when exposed to light. Its reflectivity is six times that of traditional signs. During the day, the sign appears bright white; at night, it provides the most effective and reliable safety protection for pedestrians and workers in the dark.
