The complex itself is a protected historical site: an on-roof system would not have kept with the rules regarding redevelopment and hence the employment of in-roof systems.
The housing cooperative will receive a compensatory feed-in tariff for 25 years. The cooperative will be paid the rate applicable on the date that the system connects to the grid. As acceptance into the compensatory feed-in remuneration program can take up to three years, the operator will initially receive payment in the form of a lump sum from their local energy provider.
"Fortunately, our integrated panels allowed us to offer the perfect solution: the panels replace the roofing material and blend inconspicuously and harmoniously into the surface of the roof. You have to look closely to see the system at all," reports Ralf Klein, member of Centrosolar AGs Board of Directors. The buildings face south, providing the perfect conditions for the solar panels.
Buderus Heiztechnik AG installed the solar panels. Christian Steiner from Buderus states that with the use of these panels, the Schaffhausen system will produce approximately 120,000 kWh of solar power each year.
