Aesthetic Solar Energy

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.

What a fantastic roof.

So much potential for shading.

[IanR]

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.

As a hater of solar panels 

These look impressive Of course they will come at a cost 

But a massive improvement on conventional panels

No different from any roof intergrated system on looks really.

Except you are paying for the roof covering in this case, rather than some 30 quid GSE module trays and no roof covering.

[Mr Blobby]

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?

[IanR]

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.

So lower efficiency modules then, and more expensive.

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 W_p.m^-2 and efficiency for these modules?

Edited December 23, 2021 by SteamyTea

[IanR]

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%

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 

 

[Kevin J]

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

its all a matter of taste really. 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 ?

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.

From who?

[Kevin J]

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
