As the Institute of the German Economy Cologne (IW Köln) reports, the expansion of photovoltaic (PV) systems in multi-family houses (MFH) is primarily driven by tenant electricity projects. These projects allow tenants to directly use the solar power generated on-site, which brings both ecological and economic benefits.
Tenant electricity projects provide an attractive opportunity to support the energy transition in urban areas, particularly in multi-family houses, where the installation of photovoltaic systems is often simpler and more cost-effective. Tenants benefit from lower electricity prices, while the operators of the systems can profit from feed-in tariffs and the direct marketing of the electricity.
However, tenant electricity projects face challenges, especially regarding financing and legal frameworks. The EEG compensation, which represents an important source of income for many operators of photovoltaic systems, is not always accessible for tenant electricity projects. This leads to many projects needing to be realized without this funding, which can affect their economic viability.
According to IW Köln, the development of tenant electricity projects has increased in recent years, but the number of realized projects remains below expectations. One reason for this could be the uncertainty regarding legal frameworks and financial incentives.
The federal government has taken various measures in recent years to promote the expansion of renewable energies; however, specific regulations for tenant electricity projects are often inadequate. Experts therefore call for a revision of the legal frameworks to increase the attractiveness of tenant electricity projects and accelerate the expansion of photovoltaic systems in multi-family houses.
In summary, tenant electricity projects represent a promising solution for utilizing solar energy in urban residential complexes. Nevertheless, it is crucial to overcome the legal and financial hurdles to fully exploit the potential of these projects. The discussion surrounding EEG compensation and its impact on the economic viability of tenant electricity projects will continue to be a central topic in the energy transition.
