Heat pumps use electrical energy to make available the heat stored in the ground, water, or air. When combined with a photovoltaic system, a significant portion of the required electricity can be generated from solar energy. This means greater independence from utility providers and reduced energy costs. However, heat pumps aren’t the only systems that can operate on solar energy. Self-consumption is also possible with household appliances, consumer electronics, and electric vehicles. However, to ensure efficient operation, all components must be optimally matched. Furthermore, energy storage is essential for optimal energy supply. Viessmann offers suitable system solutions that integrate heat pumps with photovoltaic systems (PV) and enable innovative energy management.

Viessmann system solutions for high levels of self-sufficiency and efficiency
Using renewable energy sources saves resources and reduces emissions. However, this makes sense not only from a climate protection perspective. Energy independence can be increased by using ambient energy and solar power. Therefore, rising energy prices play a lesser role. This means greater planning security even during potential energy crises .
The combination of a Viessmann heat pump and a photovoltaic system provides the optimal foundation for this. Vitocal heat pumps extract thermal energy from the air or the ground. Thanks to their various designs and output levels, they can be used in a variety of applications – both in new and existing buildings. Photovoltaic systems can be retrofitted with Viessmann heat pumps or planned directly. This is particularly convenient when using the complete Vitovolt system. In addition to the modules, the photovoltaic system also includes a mounting system and inverters. The latter convert the direct current generated by the photovoltaic system into alternating current, making it suitable for domestic use. Additional components, such as energy storage devices, increase the efficiency of the entire system.

Innovative energy management for heat pump and photovoltaics
What is the energy output of your photovoltaic systems, what is your heat pump consumption, and what is your level of self-sufficiency and independence? For a comprehensive overview and unlocking optimization potential, Viessmann offers innovative energy management solutions.
Energy flow management and accounting using the platform
A system consisting of a heat pump with photovoltaic cells and energy storage achieves maximum efficiency with Viessmann One Base . The new platform integrates Viessmann systems with existing smart home apps to create a unified climate and energy solution that can be easily expanded, for example, with a wallbox for charging an electric vehicle. All Viessmann digital services can also be integrated into One Base. Members of the ViShare energy community receive an individual, single electricity tariff. They also receive 100% green electricity from the community, even if their own production is insufficient. The heat pump, photovoltaic systems, and other components are controlled via the ViCare app using a smartphone or voice control.

All data about power system components is always at hand
The GridBox integrates all electrically powered components of the Viessmann energy system, making it the ideal complement to an energy storage system, heat pump, and photovoltaic system. The Energy Dashboard visualizes the energy flows of individual system components and, in addition to current system data, provides daily trends and weekly reports that provide insight into energy balances and CO2 reductions. At the same time, the optimization function helps achieve the highest possible efficiency from the individual components.
Proper planning of a heat pump with photovoltaics
If you want to operate a heat pump with photovoltaics, both components must be coordinated with each other and with your specific circumstances. The design of the photovoltaic system plays a key role here. It determines the performance and thus influences how well the heat pump will capture solar energy – even in winter. This should always be the result of a customized calculation, which, in addition to calculating the heating load , also takes into account the consumption behavior of the building’s occupants. Our experienced partners are reliable partners when it comes to designing photovoltaic heat pump systems. Their expertise also allows them to provide information on possible and necessary measures to ensure all the prerequisites for the operation of the new energy system. This can be especially important if a heat pump with photovoltaic systems is being installed in an older building.
