- Explanation
-
The transposition to the module plane and the thermal correction rely on an engine verified by comparison with the reference library pvlib. This conformance concerns the computation. The accuracy of the resource against ground measurements is established by the calibration residual.

GHI calibration residual at the 80th percentile
- Measure description
-
The GHI calibration residual against ground measurements, at the 80th percentile, ranges from 2.4 to 5.8 % across sub-prefectures (median 3.4). The per-sub-prefecture value is carried in the layer.

-
DNI calibration residual at the 80th percentile
- Measure description
-
The DNI calibration residual, at the 80th percentile, ranges from 6.0 to 16.2 % across sub-prefectures (median 6.5), reaching two to three times the GHI residual in the cloudy south. The direct resource is less bankable. The per-sub-prefecture value is carried in the layer.
