Cleaning frequency depends on dust at the site. [Download the solar checklist (CSV, opens in Excel) CSV, opens in Excel or Google Sheets · 1 KB · free to edit Download](https://servicepilot.in/downloads/solar-plant-maintenance-checklist.csv) Rooftop and ground plants lose output quietly: dust, a loose connector, an inverter fault nobody saw. A solar plant maintenance checklist used on every visit catches these early and shows the customer what their O&M fee buys. Download the CSV and set frequencies per plant. Work on live DC circuits only with trained staff and the makers' safety instructions. ## Solar plant maintenance checklist: items ### Modules - Cleaning with water as per cycle; no abrasive tools - Visual check: cracks, hot spots, discolouration, bird droppings, shading from new obstructions ### Structure - Fasteners tight, no rust, clamps in place - Roof penetrations and walkways safe ### DC side - Connectors and cables: no damage, properly clipped - Combiner / junction boxes: fuses, SPDs, no water ingress ### Inverter - Display and alarm log, ventilation clear, fan working - Monitoring connection online ### AC side and protection - AC distribution box, breakers, cable terminations - Earthing connections and lightning arrester ### Performance - Generation since last visit vs expected; note any drop ## Frequency Set cleaning by site conditions, a visual and inverter check on each visit, and a detailed electrical check at a longer interval agreed in the [solar AMC contract](https://servicepilot.in/blog/solar/solar-amc-contract-format/). ## Plants on a schedule ServicePilot keeps each plant as a site with its equipment, creates AMC visits on the cycle you set and records the checklist on the job.
