2.1 Care and maintenance
There are several periodic maintenance requirements for hybrid solar panel installations. The following
table summarizes the inspections and actions to be taken to obtain the maximum performance of the
system.
Action Recommended frequency
Glass cleaning Quarterly
Solar fluid test Quarterly
Pump performance test Quarterly
Pump status manufacturer's recommendation
Controls. Settings check Quarterly
Electrical system Annually
Piping system Quarterly
The detailed maintenance plan for the system is detailed in section 7 of this manual.
2.1.1 Cleaning and inspection of the external system
WARNING:
Disconnect all electrical power before performing any maintenance work. Follow proper
lockout/tagout procedures to ensure that electricity cannot be inadvertently turned on while work is
being done. Failure to disconnect power before performing maintenance could result in death or
serious injury.
Frequent cleaning of the glass surface is important so that dirt does not affect the performance of the
panel. An accumulation of dust or dirt on the front face of the panel will cause a decrease in energy
production.

Surface cleaning should be done at least quarterly, after dust storms or after other weather
events that may cause a build-up of dirt and particles on the glass resulting in limited solar
absorption.

Use a mild soap solution in spray bottles, a rubber squeegee and soft cloths to clean the panels.

Examine hybrid solar panels for signs of deterioration (cracked glass or wiring, loose wires or
conductors...).

Check all wiring for possible damage from rodents or the weather and make sure all connections
are tight and free of corrosion.

Check for electrical leakage to ground.

Check screws, mounting brackets and control components to make sure they are tight.
