Entire solar roof would be awesome but a lot more difficult and time consuming than a panel install.
Solar panels and battery - any real world reccomendations?

My main concern would be reliability. There's a lot of potential points of failure. Does each panel/tile show its output/status?

Would be nice if they told us the cost of the system....but its a pretty neat install
It costs £lol but that will be a house that also costs £lol so it fits in just nicely.
Power walls are near £10k installed here, that house had either 2 or 4?
I watched a video last night of someone installing 3x 20kwh libi units into a house and they already had a huge battery storage setup and a huge field mounted solar array. I’ve got no idea why you’d need so much in a house…
There is a lot of money floating around still…

I haven't looked at Tesla tiles for a very long time but I remember the concept of them were they were kind of an image with the solar tech on top so it was pretty easy to have different designs. They 'could' have had a similar looking tile to what was on there originally. In the video they were nice but the roof did seem very black and shiny and a bit out of place at the location, but sill looked good.
With people moving completely to electric for heating and EV cars I can see people using 60Kwh batteries...if you had enough solar to fill them up you can run a bitcoin miner or two. Free bitcoin from the sun

I'm not sure. In a way, I think EVs will limit the useful size of home batteries.With people moving completely to electric for heating and EV cars I can see people using 60Kwh batteries...if you had enough solar to fill them up you can run a bitcoin miner or two. Free bitcoin from the sun
I was thinking about getting another home battery to up our storage. However we've now got a 2023 EV coming and it'll have a 95kwh battery. So, there's very little point having more storage in a battery than we use in the window between the 'big' EV getting charged overnight.
Spare solar during the day may as well go straight into an EV instead of a home battery.

had someone round today to measure loft they said it looks really good.
Internal measurements of loft were 6.1m Width and 4m length with 4m rise with 32 degree pitch but when I enter the rise and length I get this, what am I missing?
They also said 3x3 panels, no chance for 10 so won't even get a 4kw system

why do you need the above when they have already told you the measurements and what can be fitted??had someone round today to measure loft they said it looks really good.

just wanted to double check
Soldato
I'm not sure what your're counting as width / length, or what shape your roof is.
What size panels are being quoted for?

I confused myself on that, but this
Trina 425w panels, they do do 430 but none in stock currently.
9x425w Panels + 2x 9.5kw GE batteries = £13,261
9x425w Panels + 3x Solax Triple Power 5.8kwh = £13,128

How would you end up with 3x3 panels on a roof that shape?
Soldato
6m x 4m should be fine for 3 rows of 3 landscape, assuming typical 1.8 x 1.2 (ish) dimensions
The 3.6 vs 4m is a little tight but not outside what some will fit
For clarity the array will be around 5.4x3.6m with gaps allowed for

6 x 4 is the dimensions of the loft though, not the roof. And, according to that diagram, there's a peak in the middle? I'm confused.
Not that it changes anything. If that's what they've measured - that's what'll fit. I expect they know full well what they're doing.

OP should put up pic of proposed panel layout done in Paint or something.
Soldato
True, my suspicion is one of them dimensions is off.
If its really only 4 meters deep then its 13 feet roughly so would be an odd shaped house for sure, like a 2 up 2 down but with the rooms crosswise rather than depthwise
Bear in mind post 7760

I did say a 3 x 3 array would likely fit

This is what was in the quotation
They know its a pitched roof, this is what the chap wrote down
Its all french to me but im guessing the 4x6 is the inside loft area (Although measuring from corner to corner of home the 4m is ~2m short when I went down the alleyway) and I was told and floor to ceiling was 4m I was told over phone.
Edit
This was their original quote
Was hoping to go with a bigger system for a 5kw inverter for the higher load that can be delivered to house before feeding from grid, might get an extra battery though.

You can have as large an inverter as you want. If the DNO requests it to be capped thats for export only.
There could be a very minor efficiency loss with a larger one (most seem to quote same efficiency anyway when I was looking)*, and it will cost slightly more.
*Some larger ones have slightly higher startup voltage, its pretty irrelevant unless its significantly different.

But you cant have a bigger system as the panels wont fit…….to fit four panels in landscape, that would be 4 x 1.67 = 6.68mtrs.This is what was in the quotation

You only have 6.1mtrs
