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

Look for persistent error codes, a sudden drop in power production, unusual humming noises, or a complete shutdown. If your monitoring app shows zero production on a sunny day, the inverter is the first place to check. It's always worth getting a professional assessment for your specific needs.

This is one of the most common questions we get. For homeowners in Johannesburg, 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.

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 in the Johannesburg area.

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.
