Thanks to an Industry 4.0 coupon from ACCIÓ, Àliter Group has carried out research to develop a virtual pyranometer capable of predicting solar radiation from images of the sun. For this, a database of images of the sky has been made and their value of solar radiation at the time they were captured has been combined. In this first phase, Àliter Group has provided more than 100,000 images labeled with the radiation value to EURECAT in order to develop a neural network, or model, for subsequent training with the provided image-radiation pairs. In this way to obtain radiation from an image.
