1. The installation position of solar street light
- It should be installed in a place where the sun can shine and there is no shade around to ensure sufficient light.
- The installation location must do a good job of lightning protection measures, so as not to damage the street lamp in thunderstorms and shorten its service life.
- The installation location should not be close to the heat source, so as not to damage the support rod or the plastic on the surface of the lamp at high temperatures.
- The installation environment temperature should not be lower than minus 20 degrees, nor higher than 60 degrees. If installed in a cold environment, it is best to take some insulation measures.
- It is better not to have a direct light source above the solar panel, so as not to make the lighting control system misidentify and lead to miss
- Solar street light installation, its battery should be buried in the ground at the installation location and fixed with cement pouring, so as not to be stolen by the battery and installed in vain.
2. Type of solar panel
There are four different types of solar panels, and solar street lights generally use monocrystalline or polycrystalline silicon solar panels. The efficiency of polycrystalline silicon panels is 12-16%, while the efficiency of monocrystalline silicon solar panels is 17%-22%. The higher the efficiency, the higher the energy output. Although monocrystalline panels may cost you more, their energy output and better tolerance to heat are superior to other solar panel technologies
3. Lighting technology
HID and LED lights are the two standard lighting technologies for solar street lights. Generally speaking, most streets are lit with high-intensity discharge (HID) lamps. However, HID lamps consume a lot of energy and are therefore energy inefficient. In addition, they wear out much faster; therefore, they will need to be replaced every few years.
Therefore, if you need a durable and energy-efficient solar street light, HID lights are not feasible and LED lights are the best choice. Light-emitting diode (LED) lamps use microscopic microchips to emit visible light in a diode. They are very efficient and can produce bright light without burning out.
The only downside is that LED dims over time. However, this is a very slow process and LEDs do not need to be replaced for many years after installation.
In addition, LED lights are the most energy efficient, so they are the perfect choice for anyone who needs a cost-effective solar street light.
4. Battery type
All solar lights are powered by batteries, and there are 2 types of batteries, lithium batteries and lead-acid batteries.
The benefits of lithium batteries compared to lead-acid batteries :
- longer service life
- stronger temperature resistance (up to 45 degrees Celsius)
- multiple charges and discharge times (more than three times that of lead-acid batteries)
- better battery capacity to provide the right lighting efficiency
