Solar Quality Summit Europe 2026

Share this article

From 17-18 February 2026, members of the operation and maintenance (O&M), asset management, and engineering, procurement, and construction (EPC) communities, attended SolarPower Europe’s annual Solar Quality Summit Europe event in Barcelona, co-organised with Intersolar.

The event aims to advance the long-term quality of Europe’s solar and battery storage projects. This year’s conference focused on artificial intelligence (AI) in solar PV and battery storage operations, taking a closer look at the opportunities it brings for raising the quality of solar and battery storage projects across their lifecycle.

Dr. Florian Wessendorf, Managing Director at Solar Promotion GmbH International opened the conference, emphasising that; “the Solar Quality Summit Europe Conference has been designed to help stakeholders exchange ideas and insights that strengthen the resilience and long-term performance of solar and storage projects in Europe and beyond.” 

During the first ‘Smarter Solar, Stronger Systems: How AI Delivers on Quality?’ session, SolarPower Europe CEO Walburga Hemetsberger set the tone, highlighting how; “Europe is facing unprecedented challenges… Solar quality, reliability and performance are becoming ever more important. AI can deliver on this quality!” 

SolarPower Europe Project Officer Niki Fodor launched our Technical Due Diligence Best Practice Guidelines. The report provides an industry-first unified framework for assessing the technical, legal, environmental, financial viability, and bankability of hybrid utility-scale solar and battery storage projects from initial planning, through all project stages. Launching the report, Niki noted; “beyond the report’s technical excellence, it shows the collaborative nature of the solar industry. I’m grateful to the experts who have contributed.”

Also launched during the event, the third edition of the Engineering, Procurement & Construction (EPC) Best Practice Guidelines outlines best practices to improve the quality of large-scale hybrid solar PV and battery storage systems.

The second day of the conference began with two parallel sessions on: ‘The Hidden Costs of Small Failures: Designing Reliability at the Component Level,’ and ‘Inverter Reliability & Performance Protection.’ The inverters session discussed efficient, cost-effective and timely methods of ensuring compliance with cybersecurity regulations, while continuing to rely on global supply chains.

Afterwards, SolarPower Europe’s Senior Market Analyst Antonio Arruebo Lacleta moderated session on upgrading solar and storage systems, discussing how targeted interventions can transform legacy assets into high-performing, future-ready power plants. In his opening intervention, Antonio outlined how; “we already have a substantial fleet of solar and battery storage capacity. Upgrading actions like revamping can transform legacy assets into high-performing, future-ready solar power plants.”

Thank you to our co-organiser Intersolar, and our Spanish partners UNEF, the Spanish Solar Association, for supporting, and to all of our event sponsors.

One key takeaway from our event, quality data = reliable and high-performing solar PV and battery plants.

We look forward to seeing you all next year, and continuing our discussions on everything solar quality!
