Calculating Impact of Anomalies & Power Factors



The Findings table of the Raptor Maps report provides insight into the impact of anomalies on solar-site power production:

For each anomaly type, the table calculates the estimated impact by multiplying the number of modules affected by the peak power of the solar module at STC (Standard Test Conditions) and a power factor ranging from 0 to 1 (specific to the anomaly).

  • Each cell anomaly impacts the power of the associated module, so for each cell anomaly, there is an associated impact on the module, represented by the number of modules affected.
  • The peak power of the solar module at STC takes into account the specific module installed at the site, as the standard output of a module (in Watts) varies by manufacturer and model.
  • The power factor serves to reflect that, for example, a string outage will have a much greater impact on overall power production than a cell outage would have.

Please update your specific Purchase Power Agreement Rates (PPA) and Peak Sunlight Hours in Map Options to get the most accurate impact calculation.

If, in your experience, anomaly types have a higher or lower impact on affected power, adjust the power factor to more accurately estimate impact.

Note: If you are managing solar inspections for multiple clients, any adjustments you make to power factors will change the affected power calculations associated with the Findings table for all new and existing reports.
