Big Jimbo Posted August 29, 2023 Share Posted August 29, 2023 Just been looking as the GSE installation instructions. There needs to be some more real world video's showing the installation and as importantly the roof tiles being fitted. I have seen quite a few pics etc, where the tiling looks like a dogs dinner. Bit like the tiling around some roof windows. Link to comment Share on other sites More sharing options...
JohnMo Posted August 29, 2023 Share Posted August 29, 2023 Don't tiles always look a dog's dinner anyways specially when cutting around something. That's why I like slate, they are thinner and the cut edge is clean. Link to comment Share on other sites More sharing options...

Also as a side concern I understand that concrete tiiles are 'sealed' and if you cut them you expose them to the elements.. is there some way to properly re-seal them?

I would double check your quantity of the sundry bits from GSE. £98 for each panel doesn't sound right. Here is my list of bits for 10 panels When was this quote/invoice done?

dpmiller Posted August 29, 2023 Share Posted August 29, 2023 Well that's not correct. You don't need 100 screws, 5.5m of foam strip or 5m of Rooflex for *each* panel But will you not need side flashings, regardless of using the Rooflex for top and bottom (if that's what you're doing)? We went with the proper top and side trims and Rooflex at the bottom... Link to comment Share on other sites More sharing options...

Obviously I only copy/pasted from their own site - https://www.itstechnologies.shop/products/gse-in-roof-mounting-system-portrait - and the guy in question did add 23x this item. I think something screwy. is going on. I will certainly challenge them on this part, as JohnMo suggested, a more reasonable price per panel seems in the area of 50 quid (2 trays needed @ 22 GBP apparently) and then some screws, tape nuts and bolts. Did you design your system yourself? Edited August 29, 2023 by puntloos Link to comment Share on other sites More sharing options...

We had a scheme in mind, but when setting the trays out on the actual roof it became apparent that they were too tight to the valleys to flash and mount correctly and so we re-jigged to put two panels on a different face which then required purchasing a couple more bits of flashing. But the move actually suits us better in honesty as we retain production later into the evening now (but at the expense of peak output). 1 Link to comment Share on other sites More sharing options...

Does that make sense or is it still unneeded in this forum's opinion? Link to comment Share on other sites More sharing options...
JohnMo Posted September 21, 2023 Share Posted September 21, 2023 Perhaps a drawing may be neededcof your roof buildup? So we all know what the issue is you are trying to get around. Mine are on directly attached to sarking boards with a membrane above, so zero membrane droop, and then the GSE panels. Been in operation for a couple of years no issues. But if you are having tiles and not slates you will be having battens across the roof anyway, so would have a ventilation anyway below the PV and tiles. The GSE panel and PV will not be changing that. But a drawing needed really. Link to comment Share on other sites More sharing options...

If youre not modifying the GSE trays and fitting panels to GSE spec, then why would you need to change the GSE intended ventilation? On a still summers day there wont be any wind rushing around to cool the panels so you'll just be relying on convection Link to comment Share on other sites More sharing options...
puntloos Posted September 22, 2023 Author Share Posted September 22, 2023 (edited) I suppose (as a non-roof-expert) my only question is where - with a tightly laid roof tile set (forticrete interlocking tiles) - air can go in and out at all. Sure, battens means there are 'voids' below the panels, and I'm sure the GSE design can connect those voids so air can travel anywhere under the roof, but I'm not quite sure where air is let in or out of the roof? Or are the gaps between GSE tray and actual tiles sufficient to let air in and out? Here's the current roof state And here is the general roof buildup - obviously without the GSE trays listed Edited September 22, 2023 by puntloos Link to comment Share on other sites More sharing options...
