FAQ’s Related Solar Power Plant OEM (Operation & Maintenance)
What maintenance does a Solar PV system require?
The two primary aspects of maintaining a solar PV system are to regularly monitor your system’s performance through the data logger and to clean the panels about 6-10 times in a year. Beyond this, it is advisable to have your installer conduct at least two visits in a year just to check the general health of your system.
What would be the annual maintenance cost 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. Typically, the maintenance costs for smaller Solar PV systems is about 2% of the initial system cost, and for larger systems is about 1% of the initial cost.
