Solar Panels on a Westdubs Roof – Anyone Done It?

[pete_d]

Has anyone fitted solar panels to a Westdubs roof? I'd really appreciate seeing any photos of how you've gone about it.


I've got a few ideas myself, but the ridges on the roof don't quite line up with the panels I have. I also spoke with a Sika engineer who advised against using their adhesives in the valleys, as they're not designed for areas where water might sit.


Would love to see how others have tackled this – thanks in advance!

Yes, but was done by converters. I’ll see if I can take a pic tomorrow

That would be great, looking forward to seeing them.

Post up a pic of the panel sat on the roof so we can see how it sits

Excuse the state of the roof – we were down in Weymouth at the weekend and a couple of seagulls clearly took a liking to it!

I’ve just laid this panel on the roof for the photos, and I was actually surprised how little the curve shows – up until now, I’d only worked it out on paper.

The panel’s in landscape across the roof, and I’ve got three of these to install in total.

I’ve picked up some Sikaflex 252 for the job (but open to better options if anyone has recommendations).

What are people’s thoughts on installing it as-is? (Obviously I’ll be doing proper prep and giving the roof a good clean beforehand.) I'm thinking run four beads – one along each edge and one on top of each ridge. I’d prefer to avoid a full perimeter bead as I’d like some airflow underneath to help regulate the panels temperature.

Or is this not a good idea at all? Any advice or tips appreciated.

Here’s how it’s done on mine

Thank you @borat

I would swap it round so the wiring is at the back, run a bead of bonding down both sides around a inch in from the edge, and on the ridges , this will let some air under the panel to help cooling

Thanks. But I want to put 3 panels up there. So needs to go landscape. If I rotate it I would only get one maybe two.

What wattage are they ?

 

[pete_d]

100 each.

I have a Dubs roof and I used hard plastic sheet cut and fixed between the ridges to give added strength to the panel. I cannot remember the thickness I used. I first blacked wrapped the roof section before attaching these so in future if the panel.was to fail it would make it easier for removal without making the gel coat. Hope the photos help. The roofs been on 4yrs and no issues with lifting
I left gaps so any water would flow through and allow air flow to stop hot spots

How about measuring the height of the roof ridges, maybe with a tyre tread gadget.
Buy some double sided self adhesive solid rubber strips of the same height and attach to the solar panels in same direction as the roof ridges.
You could use sika flex on the two roof ridges.
I would use the rubber strips to seal the front edge of solar panels too, just leave the air gap at back edge of panel, to stop the worst of the water etc, heat will escape from the rear.
Have as many strips as necessary.
I haven’t done this, but I’m planning to do this in a few weeks time
