SolarGAN

Assessing solar irradiance on facades is challenging due to complex urban features. SolarGAN helps by introducing a Deep Learning model that generates stochastic solar irradiance time series from simple fisheye images, offering a faster, data-driven alternative to labor-intensive simulations for robust BIPV energy system design.
