Photovoltaic systems are no longer only to be found on new buildings - more and more owners of existing properties are also relying on the power of the sun. The system becomes particularly efficient with its own electricity storage unit. This maximizes self-consumption and significantly increases independence from the electricity supplier.
More self-sufficiency through battery storage
Without storage, most solar power flows into the public grid - often at low feed-in tariffs. With an electricity storage system, the energy generated during the day can be used in the evening or at night. This increases the proportion of self-consumption to up to 70 % and permanently reduces the electricity bill.
Systems have become more efficient and cheaper
Modern storage technologies impress with their long service life, high level of safety and compact design. Prices have fallen significantly in recent years, while funding opportunities remain available - for example via KfW or state programs. The combination with a wallbox or heat pump further increases the benefits.
Real added value for owners
Properties with a PV system and storage are not only energy-efficient, but also more stable in value and more attractive for potential buyers. They also offer a degree of independence in times of rising energy prices - and the certainty of actively contributing to the energy transition.
Conclusion
The combination of photovoltaics and electricity storage pays off for many owners. It increases energy efficiency, reduces operating costs and makes properties future-proof - an investment that pays off both ecologically and financially.
