Q
WHAT MAINTENANCE DOES THE SOLAR SYSTEM NEED?
A
The solar photovoltaic panels require little maintenance. No need to wash or dust. It is, however, important to place panels where they will remain clear of shade and debris. Thus you will have to wipe them off if too much snow or leaves fall on them.
Solar hot water collection arrays do not require much attention either. It does help to periodically use a window wash brush, biodegradable soap, and water to clean the tubes.
