While utility scale solar plants are maintained on a fortnightly basis, frequency of maintenance for rooftop solar panels is at least 3-6 times a year. Though, it is advisable to check your solar companies manual for panel specific maintenance care as well. In many parts of India, dusty environments might necessitate monthly module cleanings as well.

The solar panel maintenance cost is influenced by the brand and kind of solar panels installed (monocrystalline vs. polycrystalline), as well as the installation method (shed mounted, ground mounted, RCC mounted). Access is obviously critical. Costs should be low enough to be recoverable from the increased productivity of your plant due to regular maintainance.
