SESA is developing a solution that improves the performance of PV plants equipped with trackers during cloudy sky situations. Standard tracking strategies orient the solar panels towards the sun to maximize the share of direct irradiance received during clear sky days. However, the panels remain oriented towards the sun even during cloudy episodes when the direct irradiance share is almost zero.

SESA’s Tracking PV Boost solution aims to optimize the share of diffuse irradiance captured by the solar field in cloudy sky situations. We have developed a predictive control strategy based short-term solar resource forecasting model and atmospheric information extracted from images captured by our sky imager. To facilitate the integration of our solution, we integrate the mechanical constraints of the tracking systems on a case-by-case basis to respect a specific number of cycles per day.

SESA’s solution uses mixed instrumentation (a wide-angle camera and a pyranometer) taking advantage of GHI (Global Horizontal Irradiance) measurements and atmospheric observations. The forecasting algorithms are based on state-of-the-art artificial intelligence tools that are not yet widely used in the field of weather forecasting. They take advantage of information extracted from images to predict future irradiance.
