I have a friend who is planing a large garage/workshop. Oak-framed, should be rather nice. Commendably he is considering doing the roof on the south side in PV tiles, but the quotes he's had are deeply uninspiring. About 20 grand for a ~2kW system. That's nearly twice as much as normal PV panels stuck on top. Is that really the going rate for solar tiles?
Anyone here know what the good options are, so I can pass them on. He'd like to do it, but 20 grand is too much. He really would prefer the integrated PV roof because it looks nicer and it does seem more sensible when building a new building. It there really an 80-100% premium over plain panels for this tech?
This is a few miles north of Cambridge, in case it matters.

A 2.1kW panel system attached to existing roof is ~£8500 DIY and best quote I've had so far is ~£11,700 fitted. Not sure how much the tiles cost but not much - a few hundred quid?

Per m2 you mean? Not for complete roof. Just to cover the same area as the 2kw array is over 12m2. Justme |

I have no idea what roof tile prices are. A quick look online found small reclaimed slates at 40p each, which I think works out at about 600 quid for 20m2. New slates from TP are between 1.98 and 3.53 for 600x300. 20m2 seems to need about 200 of those so thats 400-800 quid. So it looks to me like one might save about 1000 by not needing slates. Which isn't nothing but it doesn't make much of a dent is £20,000.
Some interesting links (thanx), but no-one has any actual prices then?

Those prices sound about right for the cheap end of tile prices if I remember what the Housebuilding Bible says correctly. FWIW, I got a price of £50/m2 for toughened low-iron glass  |

wookey the PV panels i provided the link earlier are about 4500 euro per installed KW inclusive inverter and fitting in Germany the actual panel is about 4.1 euro per watt here http://www.innova-energie.de/assets/plugindata/poole/Sunnroof%20Preisliste.pdf but have seen it somewhere for less than that Sorry is in German Billi |

Maybe worth giving these people a call -http://www.sundog-energy.co.uk/home/ - I believe they have done integral roofs.

Wookey,
I did the sums a few years ago, as I'd figured that when PV is replacing roofing material, it might help offset the high cost. However, having checked all the sources at the time, it seemed prices were adjusted very much upwards to take into account the novelty of the product - up to 6x the price of framed PV panels!! Also, at the time, the backing materials looked cheap-and-nasty plastic - didn't look like something that would last for decades, and indeed, I've seen some (Solar Century?) on the SolarTwin demo vehicle back in 2006, where the backing material was lifting and curling like the awful synthetic slates do if they haven't had the copper retainer clips fitted. Of course, things could have moved on since then, but it put me right off the idea.

Have you tried www.jhspowersolutions.co.ukThey fit the solar century c21e integrated tile. When I looked, I think the rrp for supply only of tiles, inverter and fittings for a 1.9kwp was £13k exvat, there would be an installation cost but I assume if professionally done the LCBP grant would probably offset that. Obviously still way more than a regular installation. Regards Richard |
