    4x unused Riomay DF120 solar thermal collector arrays 2.91 * .86 * .15 metres. UK 1365 kWh per annum each.

    Direct type evacuated tubes, so can be installed on a flat roof without frames to stand them up. I think they're RHI approved.

    Offers?

    Collection from Brighton...

    Several identical panels installed on a flat roof - you can rotate the tubes so that each plate in the centre of the tube faces South, and/or angle the whole collector up along one edge, and separate them a bit to prevent overshadowing when the sun is lower in the sky...
