What is the maintenance required for a Solar PV system?

The annual maintenance and recurring costs are almost negligible, since there are no moving parts and the input fuel (sunlight) is free. For optimum performance, the system only requires cleaning of modules and basic preventive and corrective maintenance. However, for off-grid systems where batteries are used, the maintenance costs are higher on account of battery replacement every 3-5 years. To ensure high generation and low maintenance cost, regular monitoring through data loggers is highly recommended. Generally the maintenance cost is only 0.1% of the initial investment.
