Rain, Dust, Snow… And Even Bird Droppings
Solar panels are exposed to the elements throughout the year — rain, snow, bird droppings, airborne debris, and even sand blown in from the Sahara. Dirty panels do not work as effectively. A covering of grime can impede energy harvesting, with even partially obscured panels resulting in energy loss of 0.5% to 3%. Bird droppings are highly acidic, containing strong concentrations of uric acid that can damage photovoltaic panels if not regularly cleaned.
Inspecting For Damage
Sand, grit, and airborne particles can cause microscopic cracks and imperfections that worsen over time. Check panels periodically for cracks, scratches, or discolouration. Heavy snowfall — not uncommon in many parts of Scotland — can potentially stop panels performing correctly, requiring prompt action. Scotland's highest rated solar installer recommends scheduling a solar health-check if you suspect any damage.
Professional Maintenance
While regular cleaning and inspections can be performed by the owner, professional maintenance is highly recommended. An annual inspection by a professional installer can involve checking the inverter, replacing worn components, and ensuring the system is properly grounded.
Additional Maintenance Tips
- Regular inspections besides professional ones.
- Keep trees and plants trimmed to prevent shading.
- Even a small amount of shade can significantly reduce efficiency.
