SolaRes®
SolaRes® ingests only satellite images and simulation data, without a priori use of in-situ measurements for recalibration purposes, allowing homogeneity in time and space of all outputs.
SolaRes® provides the global horizontal (GHI), global tilted (GTI), and direct normal (DNI) irradiances, and the slant path attenuation (for tower CSPs).

SolaRes® estimates accurately the solar resource thanks to precise and detailed simulations of all physical processes of the radiative transfer performed by the state-of-the-art Monte Carlo method implemented in the SMART-G software which allows fast calculations through massive parallelization using graphic cards.

Architecture of SolaRes®
Consequently, SolaRes can account for various geometries of solar panels (inclination, shadows, …) with calculations more precise than those based on look-up tables and subsequent interpolations.
