Summary for decision-makers

Viessmann Climate Solutions is strengthening its offering for decentralized power generation with the new Vitovolt 300-DG photovoltaic modules and innovative heat pumps. The Vitovolt 300-DG modules, with an efficiency of 22,5%, offer easy installation, a nominal power output of 500 Wp, positive tolerance, high durability, and Certisolis certification.

All of these solutions are optimized by the Viessmann Energy Management system, which manages home energy production, storage, and consumption in real time. This connected system maximizes self-consumption, reduces domestic energy costs by up to 15%, and ensures future flexibility for integrating localized equipment.


At the Artibat 2025 trade fair, Viessmann Climate Solutions is unveiling innovations that are perfectly in line with the expectations of the French HAVC (Heating, Ventilation and Air-Conditioning) market and professionals. 

The latest Viessmann innovations for smart and sustainable home energy

  • Indeed, the supply devoted to decentralized electricity production is becoming even denser with the arrival of new photovoltaic modules Vitovolt 300-DG.
  • Viessmann will also unveil a new generation of heat pumps (Vitocal 150-A et 250-A) to particularly high yields. This offer, simplified and structured thanks in particular to the introduction of modular models et hybrid, is also characterized, for the installer, by its speed and safety of implementation with the fastest to install and most user-friendly system ever developed by Viessmann.
  • Innovative solutions which also fit ideally into the Viessmann Energy Management real-time domestic energy flow management system, the source of energy savings, favoring self-consumption and maximizing the rate of energy self-sufficiency. Discoveries…

New Vitovolt 300-DG photovoltaic modules

Available from September, these new photovoltaic solutions from Viessmann Climate Solutions are cutting-edge solutions that combine uncompromising quality, sophisticated design, and long-lasting performance. With dimensions of 1762 x 1134 mm (frame thickness of 30 mm) and a weight of 27 kg, the Vitovolt 300-DG are synonymous with rapid installation, thanks in particular to their pre-wiring and connectors. 

Although they have a nominal power of 500 Wp (108 integrated TOPCon cells, 182 x 93 mm format), it should be noted that these modules are supplied with positive power tolerances, which translates into an increase in power of up to 5 Wp.

It should also be noted that the Vitovolt 300-DG boasts an efficiency of 22,5%. In addition to 2 x 2 mm safety glass with anti-reflective coating, they boast a snow load of 5.400 Pa and a wind load of 2.400 Pa. It should also be noted that the Vitovolt 300-DG already has Certisolis certification and that an ETN (New Technology Survey) is currently underway. Finally, in a spirit of sustainable performance, Viessmann Climate Solutions adds a minimum power output guarantee of 97% after one year and 87,4% after 25 years! Public price excluding VAT and installation: 137 euros.

Viessmann Energy Management 

Remember that these Viessmann Climate Solutions innovations are directly linked to the domestic energy management system Viessmann Energy Management (Home Energy Management System). This is synonymous with real-time management of energy flows via smartphone or tablet to generate significant energy savings (up to 15% reduction in heating costs thanks to smart thermostats ensuring hydraulic balancing and communicating wirelessly with the VicCare application). Viessmann Energy Management optimally coordinates all flows in the home (photovoltaic production, storage and consumption of electrical energy – including electric vehicles – and thermoelectric energy from various equipment via the Viessmann One Base platform). Thus, this intelligent system optimally manages both the decentralized production of electricity from Viessmann photovoltaic panels – and other brands – and its storage on Vitocharge accumulation modules, for example, for excess production for later use. It also controls the consumption of devices such as Vitocal heat pumps from Viessmann (and other brands). Guaranteeing the preservation of resources and a reduced electricity bill for households, it is also particularly flexible since it can manage other devices installed subsequently.
