Cleaning activities create risk of damage to the modules and array components, as well as the potential for electric
shock.
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 the Module Cleaning
Guidelines (PD-5-804) for additional information. Failure to comply with the Module Cleaning Guidelines may void
warranty.
Broken modules should be replaced immediately.
Periodically, annually at a minimum, inspect modules for any
signs
of damage or broken glass. If broken modules are found, place material into a closed container for return to Chosen
Techno Solar Private Limited recycling program, or dispose of module in accordance with local requirements. Please
visit www. firstsolar.com/recycling for further details on the recycling program.
•
It is normal for the modules to exhibit visual irregularities which do not impact power. Series 4A Modules with anti-
reflective coated glass are more likely to exaggerate the visual appearance of normal scratches, fingerprints, and
other blemishes due to the optical properties of the glass interface.
•
Check that all electrical connections are tight and corrosion free.
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
