Solar maintenance requirements are minimal.
Solar electric systems require no regular maintenance. The system operates silently and reliably for years, the same as the electricity we expect from the utility company.
Dirt and dust accumulation on the panels will reduce energy generation slightly. Customers who wash their solar panels typically notice about a 1% increase in power immediately following the wash, but washing is not necessary. Normal rain and wind are sufficient to remove most dust and debris.
Periodic monitoring of system performance is usually all that is required to ensure that the system is operating properly. Solar performance monitoring can be done manually, but for large public systems, automatic Internet-based solar monitoring is recommended. This allows remote solar monitoring by maintenance personnel, the solar installer and any other interested parties. Internet-based monitoring can also provide interactive solar performance displays for the public, and a cool way to show off your solar.
