Flying high at Barth

Setting the scene

Barth III is the latest chapter in a BayWa r.e. solar trilogy, which has seen us develop three major solar installations nearby to the Baltic Sea Airport Stralsund-Barth. Together, they create one of the largest solar parks in the region.

Regularly used by the German Chancellor, the airport provides important infrastructure for the region. But like many small airports with high operational costs, it’s a challenge to sustain commercially.

As well as providing enough green energy to power 15,000 homes, the scheme has also secured the future of Baltic Sea Airport.

Meeting the challenge

Right from the very beginning, the 156-acre site had all the right characteristics: wide expanses of flat land, a south facing aspect and a regular shape. This enabled us to fully optimise the design of the plant.

Utilisation of high-quality modules and string inverters not only meant higher yields but also lower maintenance costs, when compared to a central inverter system.

We’re always pioneering new system designs and at Barth III we installed 3 kW of bifacial modules (glass modules that are active on the reverse), which have the potential to generate an extra 10 percent yield.

Our dedicated team constantly monitors the plant via a dedicated online system that takes data from the 1,200 invertors and transfers it to our central control room in Munich. This allows for real-time monitoring and means any issues can be quickly addressed, or avoided altogether, and that performance of the site is fully optimised.

Drone flights are also used to detect any modules that are not working to full capacity. Across such a large site, this approach is highly efficient and effective.

Getting the result

Collectively, Barth generates an output of over 50 MWp, enough green power to meet the needs of 15,000 homes. All project phases were completed on time and to budget, with the first two phases being quickly purchased by investors.

Thanks to Barth III, the Baltic Sea Airport has now significantly reduced its running costs. In fact, it’s the only airport in the region that doesn’t rely on public funds.

And across the whole site, our operations and maintenance team continue to ensure it runs at peak efficiency.

Germany’s regional minister for energy, local MP’s and the wider community turned out to celebrate the opening of Barth III and celebrate this success story.

BayWa r.e. designed and developed the very best solution for us. They took the time to really understand our us, to create a solar farm that has given our business a commercial advantage. They were a pleasure to work with and have become a valued and trusted, long-term partner to us.
