Why solar panels need regular maintenance
Solar panels have no moving parts, but they are not maintenance-free. Dust and dirt block sunlight and cut generation, especially in dry, dusty conditions. Loose or corroded connections, damaged cables and faulty earthing can reduce output or create safety risks. Regular maintenance protects both performance and your investment.
What our solar maintenance includes
- Panel cleaning to restore generation
- Visual inspection for cracks, hot spots and damage
- Checks on cables, connectors and junction boxes
- Mounting structure and fastener inspection
- Earthing, lightning protection and surge protection checks
- Troubleshooting when generation drops
