Solar system Telekom AG Rottweil Deutschland

This solar system supplies a considerable proportion of the operating energy for the absorption-type refrigeration system.
  • 503 m2 collector area on the roof of a workshop building
  • 62 collector arrays comprising 50 tubes (20 and 30 tube collectors combined)
  • 20 m3 of solar cylinders positioned outside alongside the workshop building
    3100 NARVA vacuum tube collectors
  • A large proportion of the fuel required for the air-conditioning and room heating can be saved
  • Considerable reduction in consumption costs and emission of pollutants
    System impresses with its heat output during the start-up phase including with cloudy skies and diffuse lighting
  • Free-rotating in the mount – collectors can be installed longwise and crosswise
  • Optimal alignment due to rotatable mount

Opening of the largest Canadian system for solar cooling in Woodstock, Canada

On 9 November, the Oxford Garden solar heating project began operation in the presence of the Minister for the Environment in Ontario, John Wilkinson and the Consul General of Germany in Toronto, Sabine Sparwasser. This project sponsored by the German Energy Agency DENA and the State of Ontario is currently the largest Canadian system for solar cooling and heating. At the Oxford Garden retirement home in Woodstock / Ontario, the environmentally-friendly heating and cooling system serves the 102 apartments.
  • Planning and implementation of the installation was carried out by the Proterra Solar company. 162 s-power collectors with a total of 3,240 NARVA vacuum tubes on the building’s flat roof are a visible sign of the CO2 free heat production process.

Technical details:
Collectors: 162 s-power DF20 2000/TPS inside with 3,240 NARVA vacuum tubes
Installed collector output: 364 KW
Collector surface area: 526.5 m²
Storage: 3,000 gal (11 m³)
Cooling system: Yazaki WFC-5 absorption chiller
