FAQ ABOUT PRODUCTS
> What is all in two solar street light?Integrated solar street light means that the whole solar street light system is integrated into an LED street light, that is, there is a solar panel on the street light, and the street light contains batteries, controllers, microwaves, etc. Two in one solar street light means that the whole system includes two main parts: a street lamp head(integrates LED modules, solar controllers and batteries), and an independent solar panel.
> What are the weakness of solar street lights?There are some disadvantages to solar street lights, including:
Weather dependence: Solar street lights rely on solar panels to absorb sunlight for charging. Therefore, on cloudy days, rainy days, or when there is insufficient light at night, solar street lights cannot reserve energy for the battery in time. This may result in insufficient lighting on the road and may even damage the battery due to long-term depletion.
High initial cost: The initial installation cost of solar street lights is relatively high, including solar panels, batteries, LED street lights, controllers and other equipment, which is usually 5 times or more higher than the price of AC LED street lights.
Battery and solar panel life limitations: Batteries have service life and performance degradation issues and need to be replaced regularly. Solar panels also need to be cleaned regularly to ensure their conversion efficiency, otherwise the efficiency of energy collection may be affected.
> All in one or All in two?Generally speaking, the structure of integrated and two in one solar street lights does not have a clear classification of "good" and "bad". Instead, the appropriate structure must be selected according to different usage situations and needs. Both structures have their own advantages. Integrated solar street lights are more economical, simple and easy to install, and are suitable for most areas, but installation is sometimes limited by the location of the solar panels. The two in one design is more flexible and can meet the requirements of various areas and projects, but its cost is sometimes higher because it generally requires additional brackets to install the solar panels.
