Discount Retail Chain Aldi Suisse (German family owned) logistics center in Schwarzenbach created a full-surface photovoltaic system on its roof. The implementation of the solar system begins this year. With an area of almost 25,000 square meters, the largest photovoltaic system in the canton of St. Gallen is realized.
With an area of almost 25,000 m2-this corresponds to more than three football fields-and an installed performance of 5,234 kilowatt peak, the planned photovoltaic system will be as large over a thousand times as an average system on a single-family house.
It becomes the largest photovoltaic system on a single roof in the entire canton of St. Gallen.
"The project goes well with our pioneering role in renewable energies," says Jérôme Meyer, Country Managing Director of Aldi Suisse. "It was only two years ago that we put the largest continuous photovoltaic system in Switzerland into operation on the roof of our branch." This facility with a total area of 45,000m2 went online in February 2020 and has since supplied the Perlen distribution center and many households in the region with clean solar energy. She was awarded the Swiss Solar Prize.
The planned system on the roof of the Schwarzenbach branch is expected to produce the same amount of electricity in one year as around 2,200 two-person households would consume per year. The installation is carried out in cooperation with the contracting company Sonnenpool and the Helion in St. Gallen.
"A team of our specialists for large photovoltaic systems is currently working on detail planning and prepares the construction phase for this autumn," explains Samuel Beer, COO at Helion. 'The biggest challenge is the difficult situation on the procurement market. The solar system should be installed at the end of November.'
Successful expansion of solar energy
Last year, with more than 60 locations, all suitable Aldi Suisse store roofs were equipped with solar systems. These create environmentally friendly electricity from solar energy for your own stores and the electrical charging stations on the customer parking spaces. For all new store buildings, solar systems are planned by default if the structural requirements fit. A total of around 65,000 photovoltaic modules have already started operating on Aldi Suisse roofs. With the new system at the logistics center in Schwarzenbach, the number will increase to around 78,000 modules.
