Why Solar LED Street Light has Short Lighting Hours?

Solar LED street lights are used as outdoor lights that integrate lighting and decoration. Its use in various leisure places can meet people's dual requirements for lighting and landscape. However, the lighting time of the solar street lamp is very short. What is the reason for this problem?

1. Battery needs to be replaced

Solar LED street lights mainly have five components, among which the quality of solar batteries and solar panels is the key to the normal operation of street lights. Therefore, as long as one of the parts fails, it is difficult for the street lights to operate normally. If the lighting time is short, this may be due to the decrease of battery energy storage, this is the problem of the battery, and the battery needs to be replaced. Some solar led street lights have been used for 2 years, and the battery has a problem. This is generally a lead-acid battery. Good solar street lamp manufacturers now use lithium batteries with a service life of 5 years.

2. The rainy weather is too long or the solar panels are blocked

If the lithium battery has no quality problems, then other problems must be investigated. If the sun is not enough to store energy for the battery, it may also cause the solar led street light to turn on for a short time. For example, excessively long periods of rainy weather result in limited electric energy stored by street lamps during rainy days. Therefore, the amount of charge is less than the amount of discharge, so that the battery is insufficient for a long time, resulting in shorter night lighting time. Or is the solar panel blocked by something, resulting in limited solar energy absorption. If the solar panels are blocked by the trees on both sides of the road, the solar LED street lights will be hindered from absorbing the sun's rays. Even if the capacity of the storage battery is large, the battery panel can't absorb enough solar energy, so the converted electric energy will be insufficient.

3. The controller performance is not good

As the core component of the solar power generation system, the solar controller costs only less than 10% of the total system cost, but its role is far more than that. The performance of the solar controller largely affects the power generation of the entire system. The controller adopts digital control technology, the same configuration of the controller can save 80% of electricity, and rational use of electric energy, effectively protect the battery. The product lifespan has also been greatly improved. If the poor quality of the controller affects the service life of the battery, it will cause the solar street lamp to turn on for a shorter time.

4. Poor circuit connection

The short lighting time of solar LED street lights may also be due to wiring problems. Poor line connection, battery feeding, and reduced energy storage will cause the solar LED street light to flicker. At this time, you should replace or repair the line with poor contact in time.

The market price of solar LED street lights is rather chaotic, many solar street light manufacturers reduce the price of solar LED street lights by reducing the system configuration or cost. Of course, the quality of the corresponding street lights has also declined. So when buying solar LED street lights, don't blindly pursue low prices, but look for regular manufacturers to cooperate, so that when the product has problems, it can be maintained and replaced in time to ensure normal daily life!
