High-yield photovoltaic modules of the highest quality / 25-year output guarantee
Generate your own power, reduce your dependence on major energy suppliers and avoid rising electricity prices – even 8.5m2 of photovoltaic panels can be enough to cover an average resident’s energy requirements. You can use the energy you generate to cover your own needs, store it until required, or feed it into the public power grid. In addition to high-performance and high-quality photovoltaic modules, the best way to achieve the highest possible yields is with perfectly matched system components, such as inverters and storage systems. Viessmann offers all of this from a single source.
Monocrystalline and polycrystalline modules for every application
The Vitovolt 300 series comprises monocrystalline photovoltaic modules in a black design, which deliver nominal output of up to 325 Wp, as well as polycrystalline modules with 60 cells delivering up to 285 Wp. The modules, which are suitable for installation in single-family homes, large residential buildings, and on commercial and industrial buildings, offer impressive output values, uncompromising quality and comprehensive Viessmann product and output guarantees.
Maximum security thanks to 12-year product warranty
Every Vitovolt 300 module undergoes visual and electrical quality testing. This testing comprises a seven-step procedure of various checks and inspections. We do this to ensure that every single module is of the same consistently high quality. Due to this high standard, Viessmann offers a 12-year product warranty and an output guarantee that the modules will deliver at least 80% of their nominal output for 25 years.
In addition, all modules have exclusively ‘plus’ output tolerances on delivery. This means that the actual output may be up to 5 Wp higher per module.
Exceptional solar architecture thanks to attractive design
The Vitovolt 300 photovoltaic modules are available in various designs and dimensions. Take, for instance, the monocrystalline modules in a black design: they feature a black, anodized frame, monocrystalline cells in a particularly dark hue, and black Tedlar film. The result is maximum output and a premium design, ensuring exceptional solar architecture.
System is quick and easy to install
The mounting system is precisely tailored to the photovoltaic modules’ design, offers maximum flexibility in installation, and is particularly straightforward as only a few components are required. As the mounting fixtures are exclusively made from stainless steel or corrosion-resistant aluminum, all components are highly weather-resistant and durable. We offer a range of solutions for different roof coverings, suitable for both flat-roof and pitched-roof installation.
Innovative OneTurn technology means that modules and profiles can be installed particularly quickly and easily. Turning the OneTurn connector 90° – until the noticeable stop – gently tightens the connection in the base profile. Turning it a further 270° fixes the components firmly in place. This connection can then be loosened again at any time.
Perfectly matched inverters and electricity storage systems
We offer inverters for single-phase and three-phase power inputs, perfectly matched to the photovoltaic modules. These inverters facilitate a reliable and fully compliant parallel processing mode.
Vitocharge and Vitocharge HS electricity storage systems perfectly complement our photovoltaic systems. If self-generated electricity is not currently required, these systems store it so that it can be used at a later time – such as for lighting in the evening or to power a heat pump at night. This maximizes the use of self-generated electricity and further increases homeowners’ independence from the public power supply.
GridBox: Overview of power yields and consumption
With the innovative Viessmann GridBox, homeowners can always keep one eye on the output of their photovoltaic modules, the charging state of their electricity storage system, and their household’s consumption. As a centralized unit, it makes energy flows transparent and connects electrical components. You can also integrate a heat pump, the Vitovalor fuel cell heating device, or a charging station for electric cars. Homeowners can therefore gain an overview of the state of all connected components at a glance.
Completely independent with ViShare
The ViShare Energy Community brings together private electricity producers and consumers to form a smart network in which they can all use the sustainable power they generated together. At the same time, each member personally contributes to the energy transition and climate protection.
ViShare members can use up to 100% of their self-generated energy. If more power is generated than can be used or stored on site, the surplus electricity flows into the Community's electricity pool. This means that not a single kilowatt hour goes to waste. The amount of electricity each power-generating member feeds into the pool is available for them to withdraw when they need it. Members can also draw any additional electricity they require from the pool. This is then charged based on the individual ViShare tariff model.
If, at any point, ViShare members require more electricity than they jointly produce, Viessmann covers this additional demand using its own decentralized, CO2-neutral power stations – such as its solar parks.
