The Best Solar Led Street Light Manufacturer

How to distinguish the quality of solar street lights?



With the acceleration of the urbanization production process, the acceleration of the production of urban infrastructure, and the country's emphasis on the development and production of new cities, the market demand for solar street light products has gradually expanded. For urban lighting, traditional lighting equipment consumes huge energy and has huge energy waste. Solar street lights can reduce lighting and use electricity, which is an important way to save energy.

Relying on its technical advantages, solar street lights use solar panels to convert electricity into electricity for lighting applications, thus breaking the limitations of traditional street lights using city electricity, completing the self-sufficient lighting of cities and villages, and dealing with the high consumption of city electricity. , The trouble of high electricity bills. So, how to choose solar street lights and how to distinguish between their good and bad, the following is a simple analysis.

solar street lights

1. Solar panels: There are two types of solar panels: monocrystalline silicon and polycrystalline silicon. Generally speaking, the conversion rate of polysilicon is usually 14%-19%, while the conversion rate of monocrystalline silicon can reach 17%-23%.

2. Battery: Good-quality solar street lights must ensure satisfactory lighting time and brightness. As long as this point is achieved, the battery requirements are naturally not low. Nowadays solar street lights generally use lithium batteries.

3. Controller: There are two kinds of controllers: PWM and MPPT, which can reduce the overall brightness during the time when the car is scarce, thereby saving energy. Set a reasonable power after different periods of time, thereby prolonging the lighting time and battery life.

3. Light source: The quality of LED light source has a direct impact on the application effect of solar street lights. Generally, LEDs have heat dissipation problems, and have low light efficiency, relatively fast light decay, and short light source life.
