Solar collector element for water drainage has a frame of sections with mitre joints, a wall section across a fixed link, a leg from this link to the frame's inside to support a cover panel and another leg for holding a sealing section.

摘要

A frame consists of two different sections. Second legs (22) of two opposite sections (3) are off-center to second legs (23) of other sections (2), so that channels (24,25) formed by the first and second legs (20,22,23) and a fixed link (19) merge and are open on their side in a mitre joint. A flexible support section (21) clips on for a glass pane (5).
