Solar repairs and maintenance

needs

The most common components needing repair are the solar panels (for damage), the inverter (for electronic or software faults), and the batteries. Wiring and connections can also degrade over time.

Here's what you need to know. Look for persistent error codes, a sudden drop in power production, unusual humming noises, or a complete shutdown in the Durbanville area. If your monitoring app shows zero production on a sunny day, the inverter is the first place to check.

Yes, absolutely. Shorter daylight hours and a lower sun angle mean lower production in winter. This is normal and not a sign of a fault unless the drop is significantly worse than in previous years. It's always worth getting a professional assessment for your specific needs.

Panels typically have a 20-25 year performance warranty, while inverters and batteries have shorter, separate warranties (usually 5-10 years). Refer to the documents from your original installer.

From a practical standpoint, in South Africa, professional cleaning for a standard residential system typically costs between R800 and R2,500, depending on the size and accessibility of your roof.
