The solar energy market in today’s social environment appears to be quite complex. There are many different types of solar street lights available in real life, and when we consider choosing them, we may need to make more selections based on various conditions. However, most people are not particularly familiar with the actual conditions of different solar street lights.
When selecting solar street lights, one should look at the actual situation of the street light. Solar panels can be categorized into monocrystalline and polycrystalline types. Generally, monocrystalline panels have a higher conversion efficiency, while polycrystalline panels tend to have lower efficiency compared to monocrystalline ones. When it comes to power, a 100-watt monocrystalline panel and a 100-watt polycrystalline panel essentially represent the same concept, but polycrystalline panels tend to be larger in size.
In the process of choosing solar street lights, it is advisable to consider battery storage. This includes traditional maintenance-free lead-acid gel batteries or lithium batteries. Generally speaking, lead-acid batteries have a shorter lifecycle compared to lithium batteries and possess memory effects, which prevent them from being discharged fully. They can only manage about 75% depth of discharge, so lead-acid batteries are not recommended in this regard.
If you are selecting solar street lights, it is equally important to pay attention to the controllers. Different manufacturers and quality levels of controllers may have various issues. Therefore, it is essential to consider the assembly factory’s mastery of the solutions available.
