Facade collectors

Solar refurbishment with system

Especially during renovation, facade collectors offer synergy effects compensating for the lower radiation recovery resulting from the lesser effective collector arrangement:

  • Concurrent thermal insulation effect in old building renovation, approximately comparable to 100 mm heat insulation
  • Reduced complexity of the solar circulation piping
  • Much more favorable mounting options as compared to many flat roofs 
  • Clear demonstration character/ neighbourhood improvement is made visible
  • Reduced load on the collector and the heat transfer medium during idle times in summer
