Enerfin launches complete solution for solar PPAs with storage

Enerfin AG, based in Tuggen, Switzerland, and Berlin, is a fully integrated investor and provider of decentralized renewable energy and tenant power solutions. The company has launched a complete package for solar parks that combines long-term Power Purchase Agreements (PPAs) with modern battery storage systems, tailored to maximize returns while minimizing operational risks for plant operators. The offering is primarily aimed at the German market.

Under this offering, Enerfin not only finances and installs battery storage systems but also takes responsibility for their delivery and grid-supportive operation, fully compliant with Redispatch 2.0 regulations. The package is available for solar parks ranging from 1 to 120 megawatts, making it a highly flexible solution. Storage units are modular from 400 kWh upwards, lightweight at under four tonnes each, and can be distributed freely throughout the solar park for optimal placement without stressing the ground.

A key component of the service is software provided by Lynus AG, designed to shift market participation into high-price periods and to optimize battery usage on the spot market. This technology, already implemented in more than 1,500 properties and tenant power projects, allows Enerfin to fine-tune the timing of energy sales, enhancing profitability compared to direct feed-in tariffs.

Enerfin’s approach significantly reduces complexity for solar park operators by bundling financing, hardware, software, operations, trading, and administration into one end-to-end package. This removes the need for additional IT systems, lowers interface issues, and mitigates other potential risks. As CEO Paul Hauser explains: “For solar power plant operators, acquiring a battery storage system normally means extra planning, capital requirements, construction works, and coordination with traders. With our battery PPA package, we’ve made the process simple and profitable.”

The company offers three different variants: in the first, customers purchase the battery while Enerfin operates it; in the second, Enerfin finances and builds the storage facility, paying a fixed rate per MWh for production during positive market price periods; and in the third—currently the most attractive—revenues are shared according to a pre-agreed split, often delivering 15–20% more income than fixed tariffs.

Enerfin’s solution is particularly suited for Agri-PV projects and other solar parks affected by policy uncertainty, such as the delayed “Solarpaket 1” in Germany. By storing only solar power and avoiding regulatory complications associated with grid-charged storage, Enerfin enables operators to optimize their output and revenues, sometimes matching or exceeding expected fixed subsidy rates.

In addition to ground-mounted solar parks, the company also works with large-scale rooftop installations (from 400 kW upwards), including many post-EEG systems in the agricultural sector, creating new revenue streams for owners while contributing to a more flexible, resilient, and sustainable power grid.
