POAI in PlantPredict

Starting in Version 4.11, PlantPredict offers users the option to import plane-of-array irradiance (POAI) in weather files. This is a powerful tool for users who have measured or modeled POAI and wish to bypass the transposition model (and its associated error). On the backend, the algorithm uses the NREL developed GTI-DIRINT model to estimate diffuse and direct irradiance from POAI for shading calculations.
