Solar Power Plant
Risk profile for a photovoltaic power plant (roof-mounted or ground-mounted solar park): the risk attributes typically assessed in underwriting and the resulting commercial insurance programme architecture.
Risk picture
A solar power plant converts sunlight into electricity through modules, inverters and cabling that are largely exposed to the elements, whether mounted on a roof or on ground-based racking across an open site. Typical loss drivers are hail and wind damage to modules and mounting structures, snow load collapse of racking or the supporting roof, cable and connector fires from DC arcing or poor installation quality, and production shortfalls from soiling, module degradation or inverter downtime. Ground-mounted parks add exposure to grass or vegetation fires beneath and around the array, while rooftop installations tie the plant’s fate to the condition and fire behaviour of the host building.
Risk attributes to capture
The table below is generated from this profile’s linked risk attributes and grouped by category; see the individual attribute pages for underwriting logic, evidence requirements and mitigation measures.
Coverage architecture
A dedicated photovoltaic policy covers the modules, inverters, mounting structures and cabling against material damage and typically includes loss of production/yield cover, complemented by general liability for third-party injury or property damage arising from the installation. Employee accident cover is compulsory in Switzerland (UVG) wherever operations and maintenance staff are employed. Business interruption cover, aligned to the same perils and indemnity period as the property section, responds to lost feed-in revenue following an insured event, and electronic equipment cover is relevant for the inverters, monitoring and grid-interface electronics where these are not already captured under the main policy.
Prevention
Loss prevention priorities are DC-side installation and connector quality matching recognised standards to control arc-fault fire risk, racking and anchoring engineered to the applicable local snow and wind load zone, vegetation management and firebreaks around ground-mounted arrays, and a scheduled inspection and maintenance programme covering thermal imaging of connections and module performance monitoring.

Risk attributes to capture
Location
- Hail and Windstorm Exposure Zone — Hail and windstorm exposure zone records the hail-frequency and gust-speed class assigned to a location by a recognised hazard map, and is queried in property proposal forms to assess exposure to hail and windstorm events.
- Snow Load Zone — Snow load zone records the ground and roof snow load class assigned to a location by a recognised design code or hazard map, and is queried in property proposal forms to assess exposure to roof collapse from accumulated snow.
- Wildfire Exposure — Wildfire exposure records a location's proximity to forest, scrub or grassland fuel and its position in the wildland-urban interface, and is queried in property proposal forms to assess exposure to wildfire spread.
- Site Access and Accessibility — Site access and accessibility describes the road, gate and internal circulation arrangements that allow emergency vehicles and personnel to reach and move around a location, and is queried in property and construction proposal forms to assess emergency response capability.
Operations
- Planned Maintenance Programme — The planned maintenance programme attribute records whether an insured operates a documented, scheduled preventive maintenance regime for its machinery and equipment, as opposed to purely reactive repair, which is a key predictor of breakdown frequency.
- Production Capacity and Utilisation — Production capacity and utilisation record the theoretical maximum output of a site and the percentage of that capacity currently used, which together determine how much spare capacity exists elsewhere to absorb a loss and how business interruption indemnity should be calculated.
