• 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;
