Kevin J Posted December 23, 2021 Share Posted December 23, 2021 With future legislation on Green Energy I thought it worth posting an image of the Integrated Solar Modules installed on this staining seam this Self-Build at Graven Hill. increasingly popular 1 Link to comment Share on other sites More sharing options...
SteamyTea Posted December 23, 2021 Share Posted December 23, 2021 What a fantastic roof. So much potential for shading. 1 Link to comment Share on other sites More sharing options...
IanR Posted December 23, 2021 Share Posted December 23, 2021 I've been looking at similar for my own roof. There seems a bit of a premium to pay over conventional rigid module on frame (or direct bracket mounted on to seam) We're you involved in this install. 1 Link to comment Share on other sites More sharing options...
nod Posted December 23, 2021 Share Posted December 23, 2021 As a hater of solar panels These look impressive Of course they will come at a cost But a massive improvement on conventional panels Link to comment Share on other sites More sharing options...

Mr Blobby Posted December 23, 2021 Share Posted December 23, 2021 Very nice. My architect would love this. So how much do the panels cost for a standing seam roof like in the picture? I assume the Standing seam would need a ventilation gap underneath the panels? Link to comment Share on other sites More sharing options...
IanR Posted December 23, 2021 Share Posted December 23, 2021 (edited) The solar PV panels will be flexible modules bonded directly to the standing seam, either in the factory or on site. The standing seam will be fixed to an OSB/ply deck, with (probably) a vent gap underneath. Edited December 23, 2021 by IanR Link to comment Share on other sites More sharing options...

Any idea how/where the wiring goes? Surely it is easier to design in PV right from the start, than try and adapt existing systems (for new build). So what are the figures Wp.m-2 and efficiency for these modules? Edited December 23, 2021 by SteamyTea Link to comment Share on other sites More sharing options...
IanR Posted December 23, 2021 Share Posted December 23, 2021 (edited) From my research, yes, lower efficiency compared to rigid panels, ie 14%-16% Fly lead wiring is attached to one end, via a visible small junction box, well hidden under the ridge trim on the photos provided. Designing-in to a "formed on site" standing seam isn't possible, but pre formed standing seam can now be purchased with the PV modules pre-assembled. Edited to add: Efficiency now up to 17% https://bipvco.com/wp-content/uploads/2019/12/BIPVco_Metektron_LR.pdf Edited December 23, 2021 by IanR Link to comment Share on other sites More sharing options...

Planners are keen for us to exactly match the nearest neighbors slate Which looks like a solar experiment Same on our previous Which quickly decide made our minds up to leave the PV off Link to comment Share on other sites More sharing options...
Kevin J Posted December 29, 2021 Author Share Posted December 29, 2021 Focus for comparison on Yield. Currently costs are higher than Glass modules but a new, more attractive product will be available in 2022. Of course lower cost might be lower frills. The Teflon self cleaning might be an obvious casualty here. These modules do not prohibit foot traffic so are suitable for either easy install Snaplock, minimum tooling or a Traditional SS which is closed mechanically or by hand on site. Aesthetics incur cost in most purchases. Wiring in this project is at the ridge secreted in the ridge detail. The module can be wired from the rear if access is available from the loft space or at the bottom via an overhanging eaves for example No bracket and rail mounting = reduced weight, no debris build up, no vermin (pigeons) Minimum maintenance Link to comment Share on other sites More sharing options...

I'd prefer a pantile roof with GSE modules personally. Seen a lot of rip off plots on graven hill, what was your plot cost and m2 spend on build costs if you dont mind sharing ?

IanR Posted December 29, 2021 Share Posted December 29, 2021 4 hours ago, Kevin J said: We supplied the Standing Seam Snaplock system and provided technical support and installation advice to the metal roof installer. The same training is available to a Self-Builder Were the PV modules factory fitted (by you) or were they fitted on site? Do you know if the PV modules are removable, without damaging the panel coating? ie. with a 20 - 25 year life on the PV and a 60-70 year life on the SS panel, they'll need replacing at some point. 4 hours ago, Kevin J said: Currently costs are higher than Glass modules but a new, more attractive product will be available in 2022.

Kevin J Posted December 29, 2021 Author Share Posted December 29, 2021 The SS Snaplock panels were rolled to width and length and transported to Newport where the PV modules were attached. The complete units were then shipped to Bicester. The bonding process can be carried out by MSL to reduce additional transport charges. currently have no information on removal. It’s a valid question. Will revert on this shortly Link to comment Share on other sites More sharing options...
