RITTER

Ritter Solar has rapidly established itself as the largest German manufacturer of evacuated tube collectors

The Ritter Solar evacuated tube collector consists of 3 main components

  • Evacuated tubes
  • CPC mirror
  • Collecting box with heat transfer unit

Evacuated tubes

The tubes are composed of two concentric glass tubes that are half spherically closed on one side and fused together on the other side. The gap between the tubes is evacuated afterwards hermetically plugged

CPC mirror

In order to increase the efficiency of the evacuated tubes, a highly reflecting weather-proof CPC mirror (Compound Parabolic Concentrate)

Due to the particular mirror geometry, the power yield over the course of the day is almost constant.

Collection box with heat transfer unit

The collecting and distribution pipes are located inside the collecting box.
