Free lecture: Your Ü20-Photovoltaic system remains on the net!

Aichach-Friedberg, Deutschland - The sky over Bavaria becomes greener, but the days of free EEG funding for many photovoltaic systems are coming to an end. From 2025, many Ü20 PV systems, often operated by farmers and businesses, will fall out of funding. These upcoming changes leave the operators behind: Do you have to switch off your systems or are there any economic opportunities to continue to operate? An online lecture on July 2, 2025 should provide answers.

The solar expert Michael Vogtmann from the German Sonnenen Energy Society is organized in the event, which is organized by the districts of Augsburg and Aichach-Friedberg as well as the city of Augsburg, the legal situation and various usage options at the end of funding. "There is something!" The operators receive insights into the technical and economic framework of the Ü20 facilities and learn which measures are required at the turn of the year. Participation is free of charge, but a registration is at Landkreis-augsburg.de/solar lecture necessary.

self -consumption and conversion costs in the focus

What could an economic operation look like despite leaking funding? A switch to self -consumption is conceivable and could even be financially lucrative. The problem: Older photovoltaic systems often fully feed their produced solar power into the network. Technical adjustments in the meter cabinet must be made for the changeover to self -consumption, which usually needs to be carried out by a specialist company. The costs for this start at around 200 euros and can also increase quickly with more complex adjustments, especially if new battery stores have to be installed. For this, up to 2,000 euros can quickly be incurred without the memory.

How this can look economical shows a simple calculation example: a Ü20 system with 2 kWp and a yield of 1,700 kWh could generate income of 265 euros with 40% self-consumption, while expenses are only 150 euros. This results in an excess of 115 euros. This pays off to increase your own consumption and to better use the electricity generated.

market dynamics and new possibilities

The developments in the field of photovoltaics cannot be denied. It turns out that the costs for solar systems have dropped by over 80% in the past two decades. Another point that many operators should consider: an exchange of old systems for new, more powerful models. These can generate up to twice as much electricity on the same area. With a modern PV system, the feed-in tariff for new investments, which amounts to 12.73 cents/kWh (full feed) or 8.03 cents/kWh (partial feed) in 2024.

CBDR, the German Sonnenen Energy Society, emphasizes that a PV system is energetically amortized within one to two years. The lifespan is usually 25 to 30 years, which means that operators can benefit from use in the long term. Another argument for the use of PV systems is the positive climate and environmental effects. A PV system can save enormous amounts of CO₂ emissions compared to fossil fuels.

not enough! If you want to actively work for the energy transition, you can also consider changing your usage behavior. This can already be done by using electrical devices during the day. In combination with larger investments in, for example, battery storage or electric cars can be further increased. The use of solar modules in development projects also represents a further positive perspective, since functional old modules are used.

For more information and specific questions, the online lecture on July 2, 2025 is the ideal opportunity. The future of photovoltaic systems is promising and it is important to optimally use the opportunities.
