Repower brings the largest Engadine solar system to the grid
Repower has put a solar system into operation on the roof of the Upper Engadin ARA. The 5800 square meter facility is the largest in the Engadine with a capacity of 1.1 megawatts and an expected production of 1.45 gigawatt hours.
A new wastewater treatment plant is being built in S-chanf. The Upper Engadine ARA is scheduled to start operations in mid-2021. Repower has installed a solar system with an area of 5800 square meters and 3447 solar modules on the roof of the system. The plant has an output of 1.1 megawatts and an expected annual output of 1.45 gigawatt hours. That corresponds to the consumption of 325 households, writes the Graubünden energy supplier in a press release . The system was designed in such a way that it can withstand heavy snowfall. The modules themselves have a total weight of 69 tons.
The system has now been put into operation. Repower has invested 1.7 million francs.
The ARA itself is operated with a combined heat and power unit. This means that electricity consumption on site can be optimized with the aim of using as much solar power as possible on site.
