Solar street light - Wikipedia

The solar panel is one of the most important parts of a solar street light, as the solar panel can convert solar energy into electricity that the lamps can use. There are two types of solar panels commonly used in solar street lights: mono-crystalline and polycrystalline. The conversion rate of mono-crystalline solar panels is much higher than their poly-crystalline counterparts. Solar panels

Increasing Solar Panel Efficiency and Output Power

Solar panel output power may be increased via a light concentrator such as a Fresnel lens or mirror. Note that such a lens must be substantially larger than the panel. Also, concentrators may not be practical for a large array, and orientation of the mirror creates an additional tracking problem. Output may be increased by perhaps 50%. Care must be taken to prevent overheating the panel.
