Solar panels are mainly divided into monocrystalline silicon and polycrystalline silicon. Monocrystalline silicon solar panels with high conversion efficiency, can convert more solar energy into electricity, but the price is relatively high. Polycrystalline solar panels are more affordable, but have a slightly lower conversion efficiency. In all in one solar street lights, monocrystalline silicon solar panels are more widely used due to their superior performance.
The working principle of all in one solar street light is simple and subtle. During the day, the solar panel acts as a diligent collector, absorbing sunlight and converting it into electricity through photovoltaic cells. This power is then stored in the all in one lithium battery, which acts as an energy reserve.
When the sun goes down and the ambient light fades, the built-in controller comes into play. It automatically activates the LED lamps, using the energy stored in the lithium battery to illuminate the surroundings. This process does not require the intervention of an external power source, realizing self-sufficiency in lighting and providing reliable nighttime illumination for outdoor spaces.
Heat dissipation is a key issue for electronic devices, and solar streetlights are no exception. The all in one solar street light is equipped with efficient heat dissipation design.
