Solar panels need sunlight to work, and anything that blocks that sunlight reduces the power they produce. In dusty, dry regions such as Rajasthan, a thin layer of dirt can build up in just a few weeks. Many owners notice the drop only when their electricity bill goes up. Regular cleaning and maintenance prevent this.

What reduces solar output?

• Dust and sand that settles on the glass, especially in dry weather.
• Bird droppings, which can create hot spots when they dry on a panel.
• Leaves, pollution and soot from nearby trees, roads and industry.
• Shade from new buildings, water tanks or growing trees.
• Loose wiring, damaged connectors or inverter faults, which do not show up by looking at the panels.

Even a small loss, added up over a year, means units of free electricity you have paid for but are not getting.

How often should panels be cleaned?

It depends on your location and roof. Homes in clean surroundings may need cleaning every month or quarter. Sites near construction, roads, factories or open land usually need more frequent cleaning. A one-time cleaning helps after a dust storm, but a regular schedule gives the most reliable results.

Why professional cleaning is better

• Safe for the panels: the wrong brush or hard water can scratch the glass or leave stains.
• Safe for people: working on a roof needs the right equipment and training.
• Done with a check: a trained technician also notices cracks, loose fittings and shading problems.

What does an AMC include?

An Annual Maintenance Contract (AMC) is a plan under which a service provider looks after your system for a year. A good plan typically includes scheduled panel cleaning, inspection of structures, wiring and connections, checking inverter readings and a performance report, so problems are found early. Our Solar Panel AMC and Cleaning Services let you choose a monthly, quarterly or one-time cleaning plan.
