If solar panels fail or if you notice that the energy output suddenly drops, there are several steps you can take to solve the problem. Here are some suggestions:

1. Visual inspection: Visually check for any visible issues, such as damage to the solar panels, loose wiring, or problems with the mounting system. Consider safety regulations and only go onto the roof if you are skilled in such tasks.

2. Check the inverter: The inverter is an essential part of the solar panel system. Verify whether the inverter is on and if any error codes are displayed. Refer to the inverter’s manual to interpret any error codes.

3. Consult the monitoring system: If you have a monitoring system installed, review the data to see if there are any unusual trends or alerts. Some systems can even automatically notify you of issues.

4. Check for shading: Ensure there are no new obstacles casting shade on the solar panels. Shade can significantly reduce energy output.

5. Check the safety switch: Some systems have a safety switch that can be activated during malfunctions. Verify whether it is turned on.

6. Technical support: If you cannot resolve the issue yourself, contact the solar panel system installer or a qualified professional for technical support. They have the expertise to address more complex problems.

7. Warranty terms: Check the manufacturer’s and installer’s warranty terms. If the solar panels are still under warranty, the repair may be covered at no cost.

It is important to be cautious when conducting inspections and any repairs. If you are unsure of what to do, it is always best to seek professional help. A qualified installer can diagnose the problem and take the necessary steps to get the solar panel system back to optimal functioning.
