•
Periodically, annually at a minimum, inspect modules for any signs of damage or broken glass.
•
Broken modules should be replaced immediately. If broken modules are found, place material into a closed container
for return to First Solar module collection and recycling program.
•
Check that all electrical connections are tight and corrosion free.
•
Large amounts of dust and dirt on the surface of the module can reduce the power produced. Natural rainfall will
typically remove most dust. Should auxiliary cleaning be required, please refer to “FS Series PV Module Cleaning
Guidelines” (PD-5-804) for additional information.
The most common causes of lower than expected PV system power output are:
•
Inverter failure
•
Improper or faulty field wiring or connections
•
Blown fuses or tripped circuit breakers
•
Excessive amounts of dirt and dust on the modules
•
Shading of modules by trees, poles, or buildings
•
Improperly calibrated or malfunctioning monitoring equipment
