Solar street lamps can experience various failures in their solar panels during manufacturing, transportation, installation, and due to aging. The manufacturer of solar street lamps will share methods for detecting these faults.
1. Problem: Failure of the battery generation component of the solar street lamp – a busbar disconnection. This failure usually occurs during the manufacturing process, due to poor welding and issues with the soldering material.
2. Process: After the solar panels start operating, significant changes in environmental temperature can occur, leading to increased contact resistance between the cells and the busbar, resulting in much of the current converting to heat. As the current continues to flow, a large amount of heat accumulates. The wires may become carbonized, potentially leading to a fire.
3. Cause: In environments with significant temperature differences, the aging of the solder connections can be exacerbated, causing the resin backing of the solar panels to scorch and the protective glass on the surface to possibly break. If the disconnection is detected early, unique changes in output power can be observed. For instance, when monitoring power generation at the string level (the units of solar panels connected in series), the panels in the affected string can be identified by their different output power trends compared to other strings.
4. Solution: To troubleshoot solar panels exhibiting these symptoms, thermal imaging can be used, or EL (electroluminescence) checks can be performed, along with I-V (current-voltage) characteristic testing methods. This will confirm issues such as poor welding leading to disconnections.
