  • What does a TWINSOLAR compact offer?


    The efficiency of a solar collector depends on the local weather, the orientation to the sun (optimal collector alignment) and the use. The more often the sun shines during the heating period, the better the SolarAir collector can heat and ventilate, while it remains idle during the typical November fog. Depending on the climate and the use, the warm solar air can often be channelled into the building almost all year round and thus contribute to a pleasant living climat.

    When in operation, a TWINSOLAR compact - installation replaces the entire room air in less than an hour!

    Standard duration of a TWINSOLAR compact when installed in Germany:
  • approx. 2,000 hours per year
  • during the changing of seasons 4-10 hours per day
  • an average of 1-2 hours per day in winter/li>
  • a few days without operating at all (too little radiation) in winter

  • Temperature increase in the collector:
  • directly in the sun ~ 40° C
  • with cloudy skies 4 - 10° C
  • average ~ 30° C during the change of seasons
  • average ~ 17° C in winter
