Frequently asked questions: Solar cleaning in Kolkata

How much does solar panel cleaning cost in Kolkata?+
One-time solar panel cleaning in Kolkata typically costs ₹15 to ₹30 per panel. Annual maintenance contracts (AMC) cost ₹1,500 to ₹3,500 per kW per year, covering 4 to 12 scheduled visits with water filtration and electrical inspection.
How frequently should panels be cleaned in Kolkata?+
In urban and semi-arid regions of West Bengal, dust accumulation (soiling) reduces generation by 15% to 30%. Panels should be cleaned every 20 to 30 days during dry months. During monsoon months, natural rain handles most surface dust, but panels should still be inspected for bird droppings and streak accumulation.
Does dust buildup void solar panel warranties?+
While dirt does not void module manufacturer warranties directly, prolonged hotspots caused by baked-on bird droppings or heavy leaves can damage solar cells permanently. Most Tier-1 manufacturers require documented bi-annual maintenance for claim processing.
Can tap water be used to wash solar panels?+
Tap water with high TDS (total dissolved solids) leaves hard mineral scale on the solar glass when it evaporates in sunlight, permanently blocking irradiance. Professional cleaning services use demineralised or soft water with non-abrasive horsehair or nylon brushes.
