Solar panel water draining clip for flat roof

If you have solar panels on a flat roof and the panels are less then 15 degrees mounted, some water will stay in the lower edge of the panel.

After some time your panel become dirty in the lower part and it reduces photovoltaic panel power generation.

When you use this clips the water will drained. You need 2 pieces per panel.

You can buy these on aliexpress, but these are for 35 or 40 mm of thickness of the panel frame and a border of about 11 mm.

I have Q Cells PEAK DUO-G5 panels and these are 32 mm. So I made this clip for a panel with thickness of 32 mm and frame border of about 8,8 mm. This is measures are important. Warning: on Q Cells there is a difference in the frame border between portrait and landscape.

This clip (solar-water-clip-v21.stl) is for the portrait side !

Edit: I also added the clip (solar-water-clip-v21-12mm landscape.stl) for the landscape side. This border is 12mm for Q Cells. I could not test the clip myself !

Also added a part of the clip (*-profile.stl) which you can use to see if it fits or if you have to scale (X-axis).
