The Institute for Solar Energy Research (ISFH) has presented a free tool for the individual design and holistic evaluation of tenant electricity concepts.
These offer tenants in apartment blocks the opportunity to benefit from low-cost renewable electricity generated on site. However, profitability depends on many factors, which is why tenant electricity providers can hardly assess whether an investment is worthwhile without assistance. The new calculation tool is designed to solve this problem.
Programme based on Excel
The programme, which is implemented in Microsoft Excel, is based on a model that can be used to compare multivalent supply solutions. In addition to PV systems, small wind turbines and battery storage systems - previously excluded from tenant electricity subsidies - as well as combined heat and power supplies with combined heat and power plants, heat pumps or gas boilers can also be analysed.
The ecological assessment is based on the annual CO2 emissions avoided in the building, which is partly supplied with renewable energy, compared to a conventionally supplied reference building.

"Solar energy is a fundamental pillar of the energy transition. In order to further support this and to achieve our goal - a complete power supply from renewable energies by 2030 - we are further expanding our successful solar offensive: In addition to expanding the solar storage programme, which is in high demand, we are currently developing a solar register for Rhineland-Palatinate. In addition, we will also promote solar carports, balcony plug-in modules, wall boxes or agro-PV projects in the future," announced Environment and Energy Minister Ulrike Höfken during the event under the motto "Solar Offensive Rhineland-Palatinate: Investments for Climate and Economy" as part of the series "Wednesdays in the MUEEF" in Mainz today.
