ECLIPSE at ATEE 2025: Sharing Scientific Advances in Photovoltaic Measurement Technologies
The 9th November 2025, the ECLIPSE project took part in the 14th International Symposium on Advanced Topics in Electrical Engineering (ATEE 2025), held in Bucharest, Romania. Organised by the Faculty of Electrical Engineering at the National University of Science and Technology POLITEHNICA Bucharest, the symposium brought together more than 370 participants from academia, research, and industry.
This event is one of the most respected scientific forums in Eastern Europe, offering a space for experts to present emerging research, exchange knowledge, and discuss technological advancements that shape the future of electrical engineering.
ECLIPSE Contribution: Advancing Research in Residential Photovoltaic Systems
Representing the ECLIPSE consortium, the University Politehnica of Bucharest (UPB) shared their latest scientific work through the presentation of a peer-reviewed paper titled: “Development of a low-cost DC measurement circuit for photovoltaic systems using industrial equipment as a reference.”
The contribution aligns with ECLIPSE’s broader mission of fostering technological innovation that supports efficient, accessible, and user-centric energy solutions across Europe.
About the Paper
UPB’s research addresses a key challenge in residential photovoltaic systems:
the high cost of accurate DC measurement equipment.
The presented paper proposes a low-cost, high-accuracy DC measurement system developed using:
- A voltage divider integrated with a microcontroller’s ADC.
- A single-board computer for data acquisition.
- A dedicated current sensor.
- A correction coefficient derived using industrial-grade reference equipment.
This setup enables the acquisition of voltage, current, and power with an impressive average accuracy of 99.67%, making it a promising alternative to conventional industrial solutions. The proposed method not only significantly reduces measurement costs but also increases flexibility in DC applications — an important step toward more accessible monitoring technologies within residential microgrids.
This work directly supports ECLIPSE’s objective of enabling smarter, more efficient, and scalable solutions for energy-aware households.

Accurate and affordable measurement systems are essential for improving energy monitoring within residential PV systems, enhancing the performance of energy apps and services, supporting demand-response strategies, and enabling better integration of distributed energy resources. By addressing this technological gap, UPB’s research contributes valuable insights to the development of future ECLIPSE tools and pilot activities, particularly those involving residential microgrids and photovoltaic systems.
Key Outcomes of the Symposium
The ATEE 2025 symposium once again proved to be a vibrant hub for researchers, engineers, and industry practitioners. Discussions highlighted the rapidly growing importance of electrical engineering in addressing modern digital and energy challenges.
During the dedicated presentation session on measurement circuits for PV systems, UPB emphasised the crucial need for continuous innovation, cost-effective designs, and accurate field-ready solutions as the energy transition accelerates. The positive feedback received confirms the relevance of this research for both academic and industrial applications.
