5 Reasons That Solar Road Lamp Has Short Lighting Hours

As the outdoor lighting lamp, solar road lamps can be used in various places to meet people's dual requirements for lighting and landscape. They are green and environmentally friendly, easy to install, clean and pollution-free, have a long service life, and are economical and practical. It completely relies on solar power to generate electricity without connecting to the grid, and consists of batteries, solar panels, controllers, light sources, light poles and other accessories. For users, the most concern is the brightness, service life and lighting time of street lamps. If the lighting time of the solar road lamp is not long enough, its lighting effect will be greatly reduced. If the lighting time of solar street lamps becomes shorter, we must find the reason in time. So what are the reasons for the shortened lighting time of solar road lamps?

1. False standard product parameters

The lighting time of solar road lamps is related to the power of solar panels and batteries, and of course to the local sunshine time and light intensity. Some inferior manufacturers, in order to sell solar street light to customers at a low price, falsely mark the parameters of the street lights and charge them shoddy. If the configuration of solar powered street lamps is reduced, the lighting time will naturally not meet the customer's requirements.

2. Check the street light controller

Check whether the solar controller is damaged. The lighting time of the solar road lamp is mainly set by the controller. If the lighting time is unstable, consider whether the controller has water failure. The control board needs to be replaced and reset.

3. The consecutive rainy days are too long

The long-term lighting hours of solar street lights mainly depends on the ultraviolet intensity of sunlight where the street lights are installed, because the ultraviolet intensity affects the amount of solar energy absorbed by the solar cells, which is directly related to the daily power generation of the solar panels. When the solar road lamp is on a cloudy and rainy day, due to the weak light, the solar cell components cannot convert or convert less electrical energy, resulting in less charging than discharging. The long-term insufficient power of the battery will shorten the lighting time at night. When the weather improves and the sunshine is sufficient, this problem can be solved naturally.

4. The energy storage of the battery decreases

The decrease in battery storage power is also an important factor in the shortening of solar road lamps at night. The energy supply and storage of solar street lamps are completed by batteries. Commonly used solar street light batteries include gel batteries, lead-acid batteries and lithium batteries. The service life of gel batteries and lead-acid batteries is generally 3-5 years, and the service life of lithium batteries is 5-8 years. If the solar powered street lamp has been used for more than 5 years, you can basically consider replacing the battery. In order to avoid the trouble caused by frequent battery replacement, it is best to choose solar road lamps that use lithium batteries, which have a long service life and stable performance. EXC-CR-Z02 integrated solar street lgiht is a high efficiency lighting fixture that use lithium iron phosphate battery. It can provide illumination for more than 8 years without maintenance.

5. The solar photovoltaic panel is covered with dust

The main function of solar photovoltaic panels is to convert sunlight into electricity. solar road lamps are outdoor lighting lamps, and they are exposed to the outdoors for a long time. After a long time, some dust will inevitably accumulate on the photovoltaic panels. Excessive accumulation of dust will easily lead to a decrease in the power conversion efficiency, and will also cause the charging capacity to be lower than the discharge capacity, resulting in shortened lighting time. The photovoltaic panel needs to be cleaned, and the original lighting time can be restored after charging for two days. If the lighting time is still short after cleaning, it means that the solar photovoltaic panel may be damaged and needs to be replaced with a new photovoltaic panel.
