Why Solar Street Lighting Systems Don't Work in Rainy Days？

Solar street lighting systems, as the name suggests, are street lights that use solar energy to supply power and store electricity. We first need to understand the working principle of solar street lighting systems. The basic principle of solar street lighting systems is that the solar battery pack converts the radiant energy of the sun into electrical energy during the day, which is stored in the battery by the intelligent controller, and the intelligent controller controls the battery to discharge the street lights at night.  The lighting hours will be reasonably allocated based on users' requirements. In some places, there will be continuous rainy weather in the rainy season. In this environment, the efficiency of solar street lighting systems is very low, and there is even no energy conversion. Then how to ensure that the solar street lighting system source is powered? Next, let's take a look together.

Why solar street lighting systems do not turn on in continuous rainy days?

1. In the initial design of solar street lighting systems, it is necessary to consider the use of local solar resources, climate and environment and other conditions, and reasonably configure solar street lighting systems. It is necessary to design rechargeable batteries and solar panels with reasonable capacity under the condition of sufficient light to support continuous lighting on cloudy and rainy days. In actual use, some solar street lighting system manufacturers cannot reasonably configure the light systems according to local climate conditions. Or some customers pursue low prices, leading solar street lighting system manufacturers to reduce the configuration. The low performance street lights can't meet the local lighting needs for continuous rainy days. This is one of the reasons why solar street lighting systems sometimes do not turn on in continuous rainy days.

2. The quality of the lamp is bad, and the waterproof effect of the lamp can't be reached. The light source is damaged after the lamp cap enters water; in addition, nowadays, the solar street lamp generally uses the LED light source, and its own quality problems will also cause the lamp to fail to turn on. Therefore, the waterproof of LED lamps is particularly important. Good solar street lamp manufacturers pay special attention to the waterproof effect of the lamp, and generally the waterproof level must reach at least IP65. In continuous rainy weather, the solar street lighting system does not light up, and the controller may be damaged. Some controllers are not properly waterproofed, causing water to enter the controller and damage it when it rains. The charging and discharging work and lighting of solar street lighting systems are done by solar street lighting system controllers. Good quality solar street lighting system controllers with waterproof function should be selected.

3. The wiring is worn, broken, short-circuited, and the terminals are in poor contact. It has a big relationship with the construction quality, so professional construction personnel should be found for construction.

4. The battery is damaged. The quality of the storage battery is not too hard. As its capacity decreases, the storage capacity can't be reached; or the storage battery is not properly waterproofed, and the cabinet is damaged by water.

How to ensure that solar street lighting systems work normally in rainy days?

For solar street lighting systems, to meet the continuous use of rainy days for a longer time, it is necessary to increase the configuration. First, increase the conversion efficiency of solar panels. On the one hand, you can choose solar panels with higher conversion efficiency per unit area. On the other hand, you can also increase the area of the solar panels, that is, increase the power of the solar panels; second, increase the battery capacity, solar energy is an energy source that can't be continuously and stably supplied, a power storage device must be required to store the electricity and output it in a stable and sustainable manner.

In addition, the choice of quality is also very important, and the quality of accessories such as battery also affectsthe service life of solar street lamp to a large extent. Mastering the above points can better extend the lighting hours of solar street lighting systems in cloudy and rainy days.
