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.
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. See solar maintenance software and solar panel maintenance cost.
