- visually inspect PV system condition including all modules and any auxiliary equipment;
- inspect solar PV system modules for any signs of degradation;
- clean all solar thermal collectors (with low PSI cleaning and biodegradable cleaning products);
- confirm inverter operating modes (standby; startup and on);
- inspect and maintain blower intake filters and electronics section air filters;
- verify proper fan operation on each inverter;
- check the inverters heat sinks and clean as needed;
- check inverter enclosure seals for damage;
- visually inspect the condition of all inverter cables and connections, and roof-top exposed wiring and electrical connections;
- confirm power supply and transformer output;
- check module ground connections;
- complete mechanical inspection of connections and wiring;
- measure the torque of all electrical connections and re-torque as needed;
- perform a complete array electrical performance verification including visual and mechanical inspection and string level electrical tests with Solmetric Analyzer;
- inspect flashings and sealants at roof penetrations;
- inspect racking with particular attention to major fasteners; corrosion or damage; array shifting from wind; and thermal cycling damage;
- tighten any solar module mounting hardware as needed;
- remove debris and any blockage of roof drainage around racking;
- inspect for and mitigate any vegetation and pest activity; and
- complete thermal imagery in support of diagnosing any potential and actual performance issues.
