Why Is Rooftop Solar Maintenance Important?

Once your roof with solar panels is installed, they start generating clean solar energy. However, over time, factors like dust, bird droppings, pollen, and debris can reduce their efficiency.

Visual Inspection
At least once a month, inspect your roof with solar setup for loose wires, cracked panels, water pooling around mounting structures, and unusual shading due to nearby trees. Timely inspections ensure that minor issues don’t turn into expensive repairs later.

Monitor Energy Output
Modern solar systems come with monitoring tools. Keep track of your system’s performance via apps or web dashboards. If you notice a sudden dip in solar energy generation, it might signal dirt buildup or a technical issue.

Professional Annual Check-Up
Hire a qualified technician to inspect your system at least once a year. They will check inverter efficiency, inspect wiring and connections, examine the mounting structure for corrosion, and test overall system health. Annual professional maintenance ensures your rooftop solar setup continues to work at its best.

Rainy Season
You might assume rain will clean your rooftop solar panels, but that’s only partially true. Rain often leaves behind mud and mineral spots that block sunlight. After heavy rains, always check and clean your panels if needed.

Summer Season
High temperatures don’t always mean high solar energy output. Keep your panels clean and check for overheating issues, especially in hot Indian states.

Winter Season
Fog and smog reduce visibility and sunlight. Ensure your panels are free from dust and pollutants that stick during colder months.

Common Mistakes to Avoid During Solar Panel Maintenance

Using abrasive cleaning tools like steel wool, walking directly on the solar panel, ignoring minor issues like cracks or sparks, and not keeping a maintenance log can all affect performance. Avoiding these mistakes will protect your rooftop solar panels for home and help them last up to 25 years or more.
