The energy transition and the desire for greater independence from electricity suppliers are increasingly bringing photovoltaic systems and energy storage systems into focus. Photovoltaic systems convert sunlight into electricity that can be used directly in the household or fed into the public grid.
Low and zero technologies such as photovoltaic installations often include electrical energy storage systems (EESS). This section covers the types of systems available, as well as ongoing maintenance requirements and the issues to be considered in their design and installation within historic buildings.
Viessmann photovoltaic modules and energy storage systems are not only an efficient way to self-generate and use solar power, but they also integrate seamlessly into the ecosystem. For example, they can be combined with a Viessmann heat pump or charging station for electric vehicles.
Photovoltaic systems convert sunlight into electricity that can be used directly in the household or fed into the public grid. An energy storage system stores surplus electricity temporarily and releases it again when required. This significantly increases self-consumption and reduces electricity costs.
The following guidance is intended to help property owners and those involved in managing, maintaining, or making changes to historic buildings understand the issues to be considered when designing and installing solar power systems. Before installing a PV system, it is important to understand the electrical energy needs of the building users.
Storage can also provide the PV installation owner with greater resilience to be able to operate during dark hours or cloudy days when there is not enough sunshine to generate full power, as well as when there are power outages.
