Solar street lamp manufacturers analyze two major shortcomings in the application of solar street lamps

With the introduction of solar energy technology, solar energy technology began to be integrated into rural road lighting. Nowadays, all kinds of solar street lights are installed on the roadside in rural areas. They are green and energy-saving, easy to install, and are very popular among people. As the saying goes, there are no perfect objects in the world. Although solar street lights have many advantages, there are still some shortcomings in the actual application process. Today, the technicians of solar street light manufacturers will take you to analyze the two major deficiencies in the application of solar street lights.

1. Street lights often do not work for a few days after being used for a period of time.

The main reason for this problem is that the component configuration is too low, and the battery configuration may be too high, but the former is mainly the case. After a few days of continuous rain, the street lamp system battery will be over-discharged, and the controller will have over-discharge protection. At this time, if the solar power generation is too small, the battery voltage cannot reach the controller's recovery discharge voltage, and the controller and the load will always be powered off. , Module capacity is too small or rainy days are too long will inevitably lead to a long time no discharge. Therefore, it is necessary to consider the battery charging time when calculating the component capacity, and it should be fully charged within one day as much as possible.

2. The designed battery life is about ~ years, and the actual battery life is often lower than the designed life, or even less than a year.

The main reason for this problem is improper battery configuration or work. For example, the battery capacity is relatively small relative to the number of consecutive rainy days, or the battery has been in a deep cycle when it is working. The first one is the main reason.

Some solar street lamp manufacturers, in order to reduce the above problems, often set the solar street lamp controller recovery discharge voltage to be too small, which causes the battery to be in a discharged state when it is rarely charged. The battery is not used well and its use is reduced. life. Therefore, it is necessary to reasonably set the voltage at which the solar street light controller resumes discharge.
