Solar panels and battery - any real world reccomendations?

Lovely. What's your annual production look like? Do you have much battery storage?
To be honest, I've not used the software to model these changes, so you've kicked me to do it and I'll post back when done.
Last few days I've bee seeing 42 to 50kWh off 34 panels which I don't think is too bad for September and the direction of the panels.
2 x 9.5kWh batteries, but looking to double this in the future.

I'm seeing about 33 a day, May and June was much higher, highest was 57, so you will get a lot more come next year.

Hopefully, pleased with how it is currently performing - I managed just under 50kWh with the 18 No. Panels East West in June when they were the 390W ones.
I'm surprised how well the the garage side wall ones are performing.

Yeah, 25 to 35 for me this past week, sunny but feeling the morning fog. Thats Scotland west though, need to break out the winter Whiskey soon

Think I have 32 panels or similar

Presume these are mounted at 90 degree's, so vertical?

I'm thinking on doing something like this, not so keen on this design, but its 9 panels (460w Bifacial)

Problems with this design, ladder access to rear of house, potentially makes the lounge darker, generally more in your face, and more prone to wind damage.

Note: I've never got around to drawing first floor of the house, but the top panels would sit just under the upstairs windows.

Or this one which I think works better, and is less prone to the problems of the above, but only six panels.

The first picture with 6 panels only would be the way i would go and you could build them onto a sliding tray. So they could slide out and give access to everything above for the very few times you might need and can still give you power after being slid outwords.

if you catch my drift

The first picture has a total of nine, sodo you mean the second picture which has 6?

Sliding them outwards would put a lot of strain on things (too much), and would be very hard to get ladders in, initial thoughts was to build the frames so that single panels could be pivoted downwards for the few times I'd need to get ladders up there. Just loosen the bolts remove the outer arm bolts and the panel would hang down against the building.

Yes, that's correct, 90 degrees, I have six 2 rows of 3 landscape in this area, I'll find a photo shortly

I did look at a similar option to you, but on the garage, but in the end just settled on the vertical ones.

Edit: photos, please ignore plants etc, work in progress!:

That's nice, they blend in really well.
 
Hi folks,

I think I asked a while back, but given I am now nearing completion on other jobs, this may become a priority again.

I have this massive shed --- properly built on a concrete slab, with cement fibre roofing. I am thinking I can self build a reasonable install. Is this nuts to try and tackle without a proper install?

Is there any issues about having them on non-occupied buildings or non-bricks and mortar buildings etc??

Image is orientated north, so I guess the roof faces predominantly south south west? It is fairly "flat" but pitched.

What's the roof joists / frame made of? Can you attach the rails to it whilst keeping the roof water tight?

You'd get 10 panels on that easily.
Wood supported by angle iron. 3.5m spans.

The roof isn't air tight so there is potential to slide hangers through the ridge and attach to the interior roof joists. The roof panels themself are actually externally bolted too, with rubber grommets to make a water tight seal.

So I guess I'd be looking to put a metal frame attached at 3.5m centres and then attach the panels to that?

Did the calcs this morning, works out I should be generating 11,332kWh annually - that's based on no shading issues which could come into affect as the sun drops.

For reference 14.58kW at 35 degrees due South would generate 13981 kWh - so considering the different directions, angles, if I achieve this it would be about 81% of the optimum which I'd be more than happy with.

no - i was thinking the first picture without the 3 vertical ones....so just the 6 as a canopy over the deck, but the canopy could pivot forward as a unit giving you space in behind if need be for ladders.
 
Most relevant to Octopus Go customers I think but seeing as most will watch / post here anyway

Good news: we’re doubling your export rate from 4.1p / kWh to 8p / kWh.

Time to turn the diverter back off again!
Just had the email - instead of Go and SEG i'll change to Go and Outgoing lite paying 8p instead of 4p. I don't expect to export a lot over winter but i'll take it :D

Octopus Outgoing Lite
