Enough green electricity for thousands of households in Saarland – that is the goal of the Weierweiler solar park. The ground-breaking ceremony for the second construction phase of Saarland’s largest solar plant took place in the summer, but only in a small group due to coronavirus. The project, commissioned by Sunera Erneuerbare Energien GmbH, has been connected to the public grid since November 2020 and achieves a total yield of 20,000 MWh.
With a total area of 12.49 hectares, the Weierweiler solar park is not the largest project for general contractor GOLDBECK SOLAR. However, with an installed capacity of 20 MWp, the plant, which was built in two construction phases, is currently the largest in Saarland. The foundation stone for Weierweiler was laid back in 2017. This year saw the ground-breaking ceremony for the first construction phase with 10 MWp. With the completion of the second construction phase in 2020, the solar park will now have an annual yield of 20,000 MWh/a. In the long term, this will save around 10,000 tons of CO2. “The solar park extends over five individual areas just outside Weierweiler,” explains Hermann Lang from investor and developer Sunera Erneuerbare Energien GmbH. “In addition to the ecological and economic results, we also had to keep the goals of Saarland’s only climatic health resort in mind. We achieved this with the support of GOLDBECK SOLAR.”
With an investment volume of just under five million euros, GOLDBECK SOLAR installed 26,400 Suntech modules in the second construction phase alone. The solar park then has a total of just over 63,400 modules, which can supply a good 6,000 three-person households with green electricity. “The solar park will be of particular importance for Saarland in the future,” adds Hermann Lang. “The green electricity can be used to produce enough hydrogen to make hydrogen-powered cars on the Saar an attractive alternative to e-cars.” The electricity produced from the new construction phase is particularly inexpensive, costing around 5.2 cents per kWh over a period of 20 years. This makes the operation extremely attractive for the region in economic terms.
