Compare Solar Maintenance QuotesChecks You Can Do Yourself
- Look at the monitoring app weekly and compare output with the same month last year.
- Look for new error messages or warnings on the inverter.
- Keep the area around the inverter and battery clear and ventilated.
- Watch for new shading as trees grow.
- From ground level, look for visible dirt, bird droppings or damage on the panels.
Leave anything involving the roof, isolators or battery terminals to a technician.
Cape Town Maintenance Considerations
- Summer dust. Dry months from November to March leave panels dirtier; see solar panel cleaning.
- Salt spray. Coastal systems need connectors and mounts checked for corrosion more often.
- First winter rains. Moisture exposes weak connectors and junction boxes; a pre-winter check catches them.
- Wind. Clamps and rails should be checked for movement after strong south-easter periods.
Maintenance and Warranties
Some manufacturer and installer warranties expect the system to be maintained. Keep service reports. They also help when selling a property with solar.
