Regular maintenance helps ensure the system continues to generate electricity as efficiently as possible.
Why Solar Panel Maintenance Matters
Many homeowners assume solar panels are entirely self-cleaning because they are exposed to rainfall.
While rain can wash away some loose dirt, it rarely removes stubborn contamination such as bird droppings, algae, moss and traffic pollution.
Over time, these contaminants can accumulate and reduce the amount of sunlight reaching the photovoltaic cells.
Potential Effects of Poor Maintenance
| Issue | Impact |
|---|---|
| Dirt accumulation | Reduced energy generation |
| Bird droppings | Localised shading |
| Moss growth | Long-term contamination |
| Debris build-up | Uneven performance |
