Enough green electricity for thousands of households in Saarland – that is the goal of the Weierweiler solar park. The groundbreaking ceremony for the second construction phase of the largest solar plant in Saarlands took place in the summer, but only in a small circle due to Corona. The project, commissioned by Sunera Erneuerbare Energien GmbH , has been connected to the public grid since November 2020, achieving a total yield of 20,000 MWh.
With a total area of 12.49 hectares, the Weierweiler solar park is admittedly 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 already laid in 2017. This year, ground was broken 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 run, this will save around 10,000 tons of CO2.
“The solar park extends over five individual areas at the gates of Weierweiler,” explains Hermann Lang from the investor and developer Sunera Erneuerbare Energien GmbH. “In addition to the ecological and economic results, we also had to keep in mind the goals of Saarland’s only climatic health resort. We succeeded in this with the support of GOLDBECK SOLAR.”
With an investment volume of almost five million euros, GOLDBECK SOLAR installed 26,400 Suntech brand modules in the second construction phase alone. The solar park will then have 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 take on special significance for Saarland in the future,” adds Hermann Lang. “The green electricity can be used to produce hydrogen in quantities that will allow hydrogen-powered cars to be presented as an attractive alternative to e-cars in the Saar region.”
At the same time, the electricity produced from the new construction phase is particularly inexpensive, costing around 5.2 cents per kWh over a 20-year period. This makes it an enormously attractive economic proposition for the region.
