Generally speaking, the number of days that solar street lights produced by most manufacturers can work normally in continuous rainy days without solar energy supplement is called “rainy days”. This parameter is usually between three and seven days, but there are also some high-quality solar street light systems that can guarantee normal operation for more than 8-15 days in rainy weather. Today, Tianxiang, a solar street light factory, will take you to learn more about it.
Tianxiang Solar Street Light Factory develops low-power intelligent control systems with a maximum battery life of 15 days on rainy days. From lighting scheme design to wind and corrosion resistance technology, from cost estimation to after-sales maintenance, customized suggestions are provided based on years of technical accumulation.
1. Improve conversion efficiency and battery capacity
First of all, it is crucial to improve the conversion efficiency of solar panels, which can be achieved by selecting high-performance solar panels or expanding their area. Secondly, increasing battery capacity is also essential, because the supply of solar energy is not stable, so batteries are needed to store electrical energy to ensure stable power output. Finally, from a technical perspective, it is also particularly important to achieve intelligent power regulation, which can intelligently predict weather conditions, so as to reasonably plan the discharge power and meet the needs of long-term rainy days.
2. Choose high-quality accessories
In addition, the quality of accessories is also crucial. High-quality batteries and other accessories are important factors to ensure the stable operation of the entire system and extend the service life. The quality of key components such as panels and batteries will directly determine the service life of solar street lights. Taking batteries as an example, poor quality batteries will lead to rapid decay, just like the lithium batteries in mobile phone power banks. Although they have a large capacity, they cannot fully charge mobile phones after a short period of use. Therefore, when purchasing solar street lights, it is important to pay attention to the quality of each accessory to ensure that it can work stably and efficiently, thereby extending the use time on rainy days.
3. Choose a suitable installation location
The installation location of solar panels has an important impact on the performance of solar street lights. Choose places with sufficient light and no obstructions, such as roofs, open fields, etc. At the same time, avoid installing in places with more shadows such as trees and buildings to avoid affecting the photoelectric conversion efficiency of the panels. In addition, the installation angle should also be reasonably adjusted according to the local latitude and season to ensure that the solar panels can absorb sunlight to the maximum extent.
Generally speaking, solar street lights are on for eight hours a day, so most manufacturers will make them bright for the first 4 hours and half bright for the last 4 hours, so that they can be on for 3-7 days on rainy days. However, in some areas, it rains for half a month, and seven days is obviously not enough. At this time, an intelligent control system can be installed. It adds an energy-saving protection mode on the original basis. When the specific voltage of the battery is lower than the set voltage, the controller will default to energy-saving mode and reduce the output power by 20%. This greatly extends the lighting time and maintains power supply on rainy days.
Therefore, when purchasing solar street lights, be sure to tell the manufacturer clearly in which area they are installed, and then let the manufacturer configure them reasonably.
