Following numerous bureaucratic procedures, Oberbayer laments about his solar power system's meager income.

The Streffers, residents of Anzing, have been producing clean energy with their photovoltaic (PV) system installed on their roof since 2019, with a system on the south side and another added to the north side on January 1, 2023. However, their journey with this renewable energy source has not been without challenges.

In February 2023, the Streffers applied for a PV system with full feed-in according to EEG 2023. The meter for their north-side PV system was installed and approved by Bayernwerk at the end of June. The Streffers submitted the necessary form on August 8, 2023, as required by Bayernwerk for qualifying for the higher subsidy.

Despite their efforts, the Streffers have been receiving a remuneration of only 8.2 cents per kilowatt hour for their north-side PV system for the years 2023 and 2024. This low remuneration does not allow for amortization of the costs, as the new system on the north side of their house cost 13,000 euros.

The Streffers were expecting a remuneration of 13 cents per kilowatt hour, but they have received confirmation for their application in April 2023, with a "clear specification for full feed-in". This discrepancy has led to the Streffers filing a complaint with Bayernwerk about the incorrect billing.

Bayernwerk has not responded to the Streffers' arguments but has consistently emphasized the correctness of its bills. The Streffers have written more than ten emails and letters, sent two registered letters, and called Bayernwerk several times regarding the issue, but to no avail.

The Streffers primarily use the electricity generated by their south-side PV system, leaving the north-side system underutilised due to the low remuneration. This situation is particularly disappointing as battery storage systems can further increase the self-consumption rate and make PV systems more economical.

The Consumer Center advises households to use as much of the electricity they produce themselves as possible. Charging electric vehicles or running household appliances with a PV system can save money and reduce CO2 footprint. Even balcony power plants can contribute to this goal.

The regulatory authority responsible for setting the technical requirements for full feed-in systems and their remuneration in Bavaria is the Bayerisches Staatsministerium für Wirtschaft, Landesentwicklung und Energie (Bavarian State Ministry for Economic Affairs, Regional Development and Energy). Such requirements can be made through formal regulatory frameworks like the Bavarian Renewable Energy Act or related ordinances.

The Streffers' ongoing struggle serves as a reminder of the complexities and challenges that can arise when transitioning to renewable energy sources. Despite these challenges, the Streffers remain committed to their goal of producing clean energy and reducing their CO2 footprint.
