Solar Panel Cleaning Frequency: Solar panels shall be cleaned bi-annually as required based on environmental conditions (e.g., dust, bird droppings, pollution). Locations and equipment details: • 1285 Lemen Ave Woodland, CA 95695 (966) REC 345-watt modules, (8) Solectria 36 kw inverters, (1) Fronius 22.7 kw inverter • 30491 Fredericks Dr Winters, CA 95694 (742) REC 345-watt modules, (4) SMA 50 kw inverters • 664 Cummins Way West Sacramento, CA 95605 (231) REC 345-watt modules, (4) Fronius 15 kw inverters Cleaning Method: • Use of deionized water or environmentally friendly cleaning solutions to avoid damage to the panels. • Soft brushes, squeegees, or automated cleaning systems to prevent scratching of the panels. • No harsh chemicals or abrasive materials will be used. • Clean and check all combiner and junction boxes Inspection During Cleaning: • Visual inspection for cracks, chips, or any other physical damage to the panels. • Assessment of any potential shading issues or obstructions that may affect performance. Preventive Maintenance: Visual Inspection: • Inspect the structural integrity of the mounting system, frames, and fasteners. • Check for any signs of corrosion, wear, or loose connections. • Inspect electrical connections, wiring, and junction boxes for signs of damage, wear, or overheating. • IR scan all overcurrent devices and connections Electrical Testing: • Perform electrical testing to measure the voltage, current, and output of the system to ensure it is within the expected range. • Testing of inverters, charge controllers, and other associated equipment to verify proper operation. Corrective Maintenance: Repair Work: • Address any issues identified during inspections or performance monitoring, such as replacing damaged panels, fixing loose connections, or repairing mounting hardware. • Coordination with the original equipment manufacturer (OEM) for warranty-related repairs, if applicable.
