Bored Shopper Posted November 7, 2019 Posted November 7, 2019 We've been presented with two options for our PV array, in-roof and on-roof. The on-roof one requires additional 50 linear m of anti-bird protective net, which comes at exorbitant price. DH is more inclined towards in-roof solution, as the saving would be considerable. The concern with in-roof is any potential leaking around the installation, etc. Any opinions on pros and cons, please, from any happy owners of in-roof and on-roof sets, please?
SteamyTea Posted November 7, 2019 Posted November 7, 2019 I don't think there is an increased risk of leakage with an inroof system. May even be less of a risk than, what is in effect, a retro fit. If you have closely watched s PV system being fitted, you will know what I mean.
ToughButterCup Posted November 7, 2019 Posted November 7, 2019 My in-roof system is fine. Faces all the wet weather, nay borra (yet)
joth Posted November 7, 2019 Posted November 7, 2019 Many find inline systems more aesthetically pleasing. Also if you're thinking of selling at some point, surveyors can mark down on-roof installs for the extra complexity in maintaining/replacing the tiles under the panels, which puts some buyers off. (Surveyors always advise the roof tiles will soon need replacing)
Roundtuit Posted November 7, 2019 Posted November 7, 2019 Assuming you're new-build, then in-roof. Looks better, costs less. If you go for a tried-and-tested system, leaking won't be a concern. We've used Viridian Solar's in-roof stuff, but there are a number of people on here that have used different systems satisfactorily.
Dan F Posted November 8, 2019 Posted November 8, 2019 The other popular in-roof system is GSE. http://www.gseintegration.com/en/InRoof.html#

What this bird protection net? never heard of a net, hopes not like the nets on our local Sainsbury as I'm forever going in there to get that a bird is tangled in it.

It'semi-rigid netting to close off the narrow gap around the edges of on-roof PV arrays, to stop birds from roosting/nesting under the panels. The reasons for stopping birds getting into this narrow gap are to prevent damage to the electrical connections under the panels, and to prevent old nests becoming a fire risk. 1
Ferdinand Posted February 18, 2020 Posted February 18, 2020 (edited) Is netting worth a retrofit? I hate to think how much I would need. It could be 100m. Edited February 18, 2020 by Ferdinand

Might be, if you have a problem. Pigeons seem to be the birds that cause the most problems, smaller birds roosting under the panels probably aren't a major issue. The cost isn't so much the netting, as the installation, as it usually needs scaffolding or at least a scaffold tower to get up there and work safely.
Bodgerbedge Posted February 18, 2020 Posted February 18, 2020 I second/third the in-roof option - we are a 3 storey house and no problem so far, except...... the flashing wasnt properly installed so within a matter of weeks it was flapping about in the wind and had to be replaced. Of course this happened AFTER the scaffolding was taken down ?

gc100 Posted February 18, 2020 Posted February 18, 2020 Does anyone know if the in-roof systems can be used with metal/zinc roofs? I've done a search but can't find much in the Uk. Also what sort fo pricing are these systems? My current quote for a 4K system is around £1500 plus about a days work for the electrician and mounts/clamps.

I've had four back for supply and install of a 4kW system ranging from £3995 to 7 grand!
