Many areas experience continuous rainfall during the rainy season, sometimes exceeding a city’s drainage capacity. Many roads are flooded, making it difficult for vehicles and pedestrians to travel. In such weather conditions, can solar street lamps survive? And how much impact does continuous rainfall have on solar street lamps? Let’s analyze this.
As a solar street lamp factory with OEM/ODM capabilities, TIANXIANG can customize products to local specifications for overseas customers. Our 20 years of experience have not only accumulated production experience, but also a precise understanding of customer needs.
1. With current technology, brief periods of rain will not affect the performance of solar street lamps.
When selecting solar street lamp configurations, it’s important to consider the local climate, environment, temperature, and the number of consecutive rainy days to calculate the amount of energy the solar panels can generate and the battery’s storage capacity. This requires ensuring that the solar street lamp’s power and battery capacity are compatible. If the solar street lamp’s power is high and the battery’s capacity is low, the lighting time may be insufficient. 1. Continuous rainfall has a direct impact on the charging of solar street lamps.
Solar panels convert sunlight into electricity and store it in lithium batteries. If there is continuous rainfall, the lithium batteries cannot recharge properly. Over time, the remaining power in the lithium batteries will gradually deplete, and eventually the solar street lamps will stop working properly.
2. Continuous rainfall tests the waterproof performance of each solar street lamp component.
Every solar street lamp component is waterproofed before leaving the factory. The key is that the electronic components within the solar street lamp components will be affected to varying degrees by the constant impact of rain. If individual components are not properly waterproofed, they will inevitably short-circuit and burn out.
3. If a solar street lamp fails to work after continuous heavy rain, there may be a problem with the product. This can be analyzed from the following aspects:
Insufficient charging
Solar panels need time to receive sufficient sunlight to charge.
Poor battery quality
The typical battery warranty period is three to five years, but battery quality can affect performance. Using poor-quality accessories can shorten the product’s lifespan.
Controller damage
The controller’s waterproofing directly impacts its lifespan. Poor waterproofing can lead to water damage.
It’s recommended to first check the battery panel charging status and the controller’s status. If self-diagnosis fails, contact a professional repair technician.
TIANXIANG solar street lamps are IP65 waterproof, ensuring the core components remain intact even in the face of continuous heavy rain or even brief submersion. Every detail, from the sealant on the lamp beads to the cable connectors, has been engineered for waterproofing. The integrated seal design of the lamp cavity effectively prevents water from seeping in. Choose TIANXIANG and worry less about lighting in the rain.
This is what TIANXIANG, the solar street lamp factory, has to offer. If you’re looking for a rainy-season-proof light, consider our split solar street lamps, which offer IP65 waterproofing and exceptionally long battery life.
