Hi again!
Following on from my 'Effects of Shading' thread, I've pretty much decided to just go for it, keeping things as a basic array with single inverter. Anyone serving the area interested in quoting? I'm considering a 12 to 16 panel array feeding a single inverter to keep costs down.
I appreciate that a site visit is the way to go before a fixed quote can be given, but here's an outline for anyone who may be interested at this stage:
Postcode: EX39 North Devon. Roof is at a 39o pitch & exactly south-facing.
Roof area is 8m eave-to-eave x 4.15m from bottom of ridge tile to lowest tile edge. This includes a ~ 500mm overhang at each end, so the actual usable 'panel' area is likely to be around 6.5m x 3.5m ish.
The roof is on a recently-built detached garage with real slate tiles. Although detached, the power is fed from the nearby house (7m) by underground SWA which every potential installer has pronounced 'fine' (I think it's 4mm2). There is a 2-way CU in the garage (which I appreciate will have to be expanded) and the supply is fed from its own 20A MCB in the house's CU. So, no leccy cable required, and inverter will also be mounted in the garage.
As you can hopefully see from the photo, there is a stone wall running alongside the garage with a hedge on top. On the garage side there is room to walk along the top of this wall and a couple of 'installers' said they'd run roof ladders up from there and not bother with scaffolding - but that's obviously an individual decision to be made by each person.
There is a potential problem with shading from the telegraph pole you can see on the left hand side. This does - as you can see in the photo - cast a full-height shadow over the roof from about 1.30 pm onwards over 3 winter months. For around 3-4 months over summer, the shadow doesn't reach the roof at all; in the in between months, it falls over varying heights. So, should anyone wish to suggest, perhaps, a second inverter to keep the rows separate, or a 'duo'-inverter or anything else for that matter which could help with my potential shading problem, I'd certainly be interested, although my thoughts are to keep the system as simple as possible.
Thanks for your interest.
