Solar Panels Are Tough—But Accidents Happen

Solar panels are engineered to endure various weather conditions, including hail and strong winds. Most panels are certified to withstand hailstones up to 25 mm (1 inch) in diameter traveling at speeds around 23 m/s (51 mph), as per IEC 61215 standards . Additionally, many panels can handle wind speeds up to 140 mph, aligning with moderate to severe hurricane conditions.*

However, unforeseen incidents like a tree branch falling onto your panel can cause significant damage. Even if the panel appears intact, internal microcracks may develop, potentially leading to ground faults or other electrical issues over time .

Immediate Steps to Take:

1. Safety First: Do not attempt to remove the branch or inspect the panel yourself, especially if it’s on the roof.
2. Shut Down the System: For string inverter systems, turn off the AC disconnect or breaker supplying power to the inverter, then turn off the DC disconnect. This helps prevent potential electrical hazards.
3. Contact Ecotech Solar: Reach out to your Ecotech Solar service department to assess the damage and replace the panel. We’ll find an exact or appropriate replacement and restore your system to 100%.

Note: While solar panels are durable, physical impacts can compromise their integrity. Prompt action ensures safety and maintains system performance.
