The Motion Control and Industrial Applications (MCIA) Research Group at the Universitat Polit\u00e8cnica de Catalunya – BarcelonaTech (UPC) is participating in the OPTIMA project, which aims to design and develop a high-efficiency, fully integrated bifacial photovoltaic system. This system is engineered for optimal performance and adaptability, particularly for installation on flat rooftops of buildings with high energy demands, such as commercial and industrial facilities.<\/h4>

In a context marked by the urgent need to reduce energy consumption and transition toward more sustainable models, especially in commercial and industrial settings, the OPTIMA project emerges as a high-impact technological response. It is not only focused on improving the energy efficiency of photovoltaic systems but also on making them adaptable and intelligent to maximise self-consumption and reduce reliance on non-renewable energy sources.

Within this framework, the project\u2019s goal is to develop an integrated system of components that work together to maximise the use of solar energy for building self-consumption. As a demonstration project, it brings together photovoltaic, mechanical, electronic, and computational technologies, applying them intelligently in buildings to prove that clean and efficient energy generation is achievable\u2014even in large, heavily polluted urban environments. Various prototype modules of the system have already been developed.

For instance, regarding the photovoltaic panel, the proposed prototype has the particular feature of capturing energy on both sides (bifacial), with a self-orienting capability to follow the sun\u2019s path using an electromechanical system. This system can dynamically adjust to shadows cast on the rooftop itself in order to maximise the total energy captured on both sides. The project also includes the development of a low-cost weather station prototype that provides data for real-time solar tracking control. In terms of photovoltaic energy management technology, the MCIA group has developed a prototype inverter using next-generation semiconductor technology (SiC), known for its high energy efficiency. Combined with a proprietary system of sensors and communications, it enables the use of optimized tracking algorithms that improve overall energy performance while monitoring the system\u2019s health to prevent operation under suboptimal and thus less efficient conditions.

Impact<\/h4>

Compared to conventional rooftop photovoltaic systems, the OPTIMA system offers significant competitive advantages. It delivers higher electricity generation per unit of installed power (kWh\/kWp) and per square metre (kWh\/m\u00b2), thereby making more effective use of available rooftop space.

It also enables better alignment between generation and consumption hours, thereby reducing dependence on the electrical grid and the need to contract additional power. Moreover, superior efficiency in DC\/AC energy conversion is achieved thanks to the use of state-of-the-art Wide Band Gap (WBG) electronic devices, with a direct impact on increased energy output.

In the final phase of the project, the MCIA Research Center has implemented significant improvements in power electronics by using high-performance silicon carbide (SiC) transistors. Due to their low thermal conductivity, these have enabled an energy efficiency of 96%. In parallel, the center has developed a Modbus TCP-IP communication interface that enables network connectivity and data transmission to the cloud, supporting real-time monitoring and intelligent system management solutions.

Partners, Budget and Funding<\/h4>

The project, which runs for 36 months (from September 2022 to August 2025) with a total budget of \u20ac798,294, is coordinated by the\u00a0 Instituto de Sistemas Fotovoltaicos de Concentraci\u00f3n (ISFOC), part of the Instituto de Finanzas de Castilla-La Mancha group and a leading institution in solar technologies. The Eurecat Foundation also participates as a project partner.
