DigiSolar – Digital Tools for Hybrid Solar Thermal Systems

Decarbonising industry and district heating networks is one of Europe’s biggest energy challenges. DigiSolar aims to transform large-scale solar thermal (ST) systems by integrating them with other renewable energy sources, enabling hybrid-ST solutions that enhance decarbonization and energy flexibility. This approach accelerates the energy transition for industrial process heat and district heating, making clean energy more accessible and cost-effective.

The EU-funded DigiSolar project develops DS Suite, a unified digital platform that combines digital twin technology, AI-driven fault detection, supply and demand forecasting, model predictive control (MPC), and life cycle assessment (LCA). The DS Suite empowers planners, operators, and end-users with performance verification, predictive maintenance, and real-time energy optimization, to reduce risks and unlock large-scale solar thermal investments.

SPF is responsible for developing one of the core planning and modelling tools within the DS Suite, the pytrnsys-Suite, leveraging digital twins implemented in TRNSYS, while allowing planners to both investigate common systems, as well as develop their own systems. Additionally, SPF is responsible for implementing an MPC based on Optihood, a python-based framework to optimize the investment in different energy technologies.

Supported by a consortium of leading R&D institutions and industry partners—including technology providers, engineering firms, utilities, and digital solution experts—DS Suite will be validated at four European demonstration sites. The project strengthens Europe’s renewable energy leadership, accelerating hybrid solar thermal deployment across industrial and district heating sectors.

Timeline: The project started in September 2025 and it is planned to complete in August 2029.
