As we conclude another successful participation at ISH 2025 in Frankfurt, I am pleased to share some observations and insights from this premier international exhibition for HVAC and renewable energy solutions. For over two decades, Solimpeks has been a regular participant at ISH, witnessing and contributing to the evolution of renewable energy technologies and market trends.
PV-T Hybrid Systems Take Center Stage
The most notable trend at this year's exhibition was the increased prominence of PV-T (Photovoltaic-Thermal) hybrid systems. As pioneers in this technology, Solimpeks has been manufacturing PV-T hybrid collectors since the early 2000s, establishing ourselves as the world's first and leading producer in this specialized segment. It was particularly interesting to see Greenonetec debut their first PV-T product at the exhibition, alongside Abora's continued showcase of their PV-T solutions.
This growing interest in PV-T technology validates our long-standing vision of integrated energy solutions that maximize efficiency by simultaneously generating electricity and thermal energy from a single collector.
How Renewable Heating Industry Giants Are Driving Market Consolidation
The renewable heating sector was well represented by industry stalwarts such as Daikin, Stiebel Eltron, Wolf, and Vaillant. While these companies did not unveil groundbreaking new products, their presence as industry veterans remains significant in shaping market direction.
A particularly noteworthy development was the joint exhibition stand of Carrier and Viessmann Group, following Carrier's acquisition of Viessmann's climate solutions unit. This merger represents one of the significant structural changes in our industry, potentially influencing competition and market strategies in the coming years.
ISH 2025 Highlights: How Renewable Heating Technologies Are Gaining Global Momentum
ISH 2025 brought together 2,183 exhibiting companies from 54 countries, with 72% of them based outside Germany, highlighting the event's global significance. Renewable heating technologies, especially heat pumps integrated with PV and battery storage systems, took center stage in Halls 12.0 and 12.1, where major brands such as Bosch, Viessmann, and Stiebel Eltron displayed their latest solutions.
Inside Solimpeks at ISH 2025: Visitor Trends and International Engagement
Solimpeks participated with an impressive stand spanning nearly 200 square meters, staffed by a team of 10 representatives. This year, our booth welcomed approximately 1,000 visitors. Notably, we observed an increase in visitors from across Europe, indicating rising regional interest in renewable heating and hybrid systems.
Solimpeks Expands Product Line: New Thermal Storage Tanks
In line with our commitment to providing comprehensive renewable energy solutions, Solimpeks has recently expanded our manufacturing capabilities to include enameled storage tanks ranging from 200 to 500 liters. This strategic investment complements our solar thermal and PV offerings, allowing us to deliver more complete system solutions to our customers worldwide.
Renewable Energy in 2025 and Beyond: Key Trends
- Integration of Technologies: The growing interest in hybrid systems like PV-T indicates a market shift toward integrated solutions.
- Industry Consolidation: Major acquisitions and partnerships suggest a phase of market consolidation.
- Regulatory Influence: Government policies and incentives continue to play a crucial role.
