Businesses that rely on solar energy can be at risk of low power generation due to cloudiness or inclement weather causing low solar irradiance. Arbol's parametric insurance offers protection against revenue losses that stem from low solar irradiance, providing peace of mind with customized coverage.


All 50 U.S. states

Who can benefit
  • Utility-scale solar power plants
  • Commercial rooftop solar panel installations
  • Solar equipment manufacturers 
  • Energy storage facilities 
  • Off-grid solar system operators

How it works

Using ERA5 land surface solar radiation downwards hourly data, our coverage makes insureds eligible for loss payments if cumulative solar irradiance falls below the pre-selected trigger, helping manage financial risks associated with low solar irradiance.

An example structure

For informational purposes only. Actual coverage may vary by carrier.

Jason operates a remote lodge and resort that relies on an off-grid solar panel system for energy. If there is abnormal cloudiness or inclement weather for a prolonged period of time, Jason will incur significant costs to use backup generators or cancel reservations due to a lack of ability to provide hospitality services.
