Industry use case
Solar energy
Bankable irradiance history for every panel you place.
Solar developers, asset managers and lenders use PastClimate to ground production models and financing cases in a decade of real hourly solar radiation and cloud cover — from first-pass site screening to year-over-year performance checks.
How PastClimate helps
Site prospecting
Rank sites by long-run irradiance and clear-sky hours before committing capital.
Production backtesting
Replay any past year of the real hourly radiation series to validate yield estimates against PPA terms — ready today, no modeled data.
Soiling & cleaning cycles
Use real dry-spell frequency and length to schedule panel cleaning economically instead of guessing.
Bankability reports
Give lenders a defensible P50 context and a decade-long track record from a consistent global climate record.
