Frequently asked questions
How much does solar panel maintenance cost in India?
For a typical 3–5 kW home system, total yearly maintenance is about ₹8,000–₹18,000, roughly 1–2% of the system cost. Each cleaning costs about ₹200–₹400, and an annual maintenance contract (AMC) from an installer costs about ₹3,000–₹8,000 a year.
How often should solar panels be cleaned?
In most cities, clean them about once a month, and more often in dusty, industrial or coastal areas, or after heavy bird droppings. Use a soft cloth or brush with clean or DM water, never a hard brush or strong chemicals.
Is an AMC worth it for a home solar system?
An AMC is worth it while the system is under warranty and you want regular inspections and performance support. It usually includes 2–4 site visits, panel cleaning and an inverter check.
When does a solar inverter need replacing?
Most inverters last 10–15 years. Budget about ₹15,000–₹35,000 for a replacement around year 10–15; solar panels themselves last 25 years or more.
