Thinking of installing a large PV system

Hi all,
As the title says, I'm considering having a PV installation of approximately 42 X 185w panels (7.7kw) and would be interested in finding out what is a reasonable sort of price (using mono panels) for this size of installation.
Also, is there anything I should be asking re inverters/panels before giving the go ahead. Would it be better to have 1 or more inverters (all the panels are located on the same roof).

As stated in your other thread, FITs are the same regardless of the electricty company.
Having a 7.7kWp system will entail a huge, and strong, roof that will need to be South facing and not shaded.
The picture above is for a 3.3kWp system
Only systems up to 4kWp get the higher FIT rate of 41.3p/kWh. Systems from 4kWp to 10kWp get 36.1p/kWh
The only way to get the FITs is to have a MCS installer and they will advise on inverters etc.
I suspect a ballpark figure(depending on your type of panel) will be £25,000 to £30,000.0 -
Thanks for the prompt reply and I've just noticed that my other post was total mumbo jumbo so it's been edited to ask about the export tariff and not the FIT!
Your guesstimate is substantially below what I've been quoted so I may have to do a bit more searching to get a bit closer to those figures.
Has anyone actually had a similar sized system installed?0 -

Well people have reported getting quotes of around £15k for a 4kWp system see:
https://forums.moneysavingexpert.com/discussion/2416423
A system not quite twice the size should not cost double £15k.
The cost of panels is but one factor. Scaffolding, labour for installation etc should not be much more than for any system; so I would think £25k to £30k is realistic.
I don't think anyone has reported on MSE of a system larger than 4kWp.
Tesco do a large 4.2kWp system I believe - contact them.0
