I have received a quote of £11,500 for the installation above from a local company - I live in West Sussex and have struggled to find anyone else who will even quote or answer their phone at the moment. The company has panels and battery in stock in their warehouse (I understand that there is a newer version of the GiveEnergy battery out soon).

I work from home full time and my wife is at home all day too, so we can certainly make the most of daytime energy by doing washing, tumble drying, etc and we added the battery for evening supply when the kids are home from school. Cooking is electric hob and oven.

House is south facing and roof is not shaded. We have a huge pigeon population locally as well as crows, magpies and a host of small birds, so I think the birdblocker is needed.

From what I have read this quote seems quite high, but I guess with energy prices shooting up it’s a supply and demand thing. I would appreciate any thoughts on whether this is reasonable in the current climate or if anyone knows of another supplier who covers West Sussex.

    I had quotes for a similar installation last November: £10,200, £11,000 and £13,800. Prices do appear to have gone up since, so your quote does not look unreasonable. However, due to a lack of Givenergy stock, I ended up with Huawei.

    I think that's reasonable especially if everything is in stock.

    Thanks I guess I had read too many articles saying you could get a system installed for around the £7k range...but I do appreciate this is possibly larger than standard and has a battery included

    My panels and battery are now installed and I'm glued to the Givenergy app watching generation.

    We've not had any paperwork yet from the installers (it was only finished a couple of days ago) - we authorised our installer to do the DNO application. Naive question, but what paperwork should I be expecting now everything is in place and working?

    Ideally, you should receive an MCS certificate,  Building Regulations Compliance Certificate and warranty documentation. If you haven't yet paid the final installment, then see if you can hold off until the documentation has been provided.

    I have the option to extend the warranty on our GivEnergy inverter from 5 up to 10 years for a cost of £295. How long does an inverter typically last and does this cost seem reasonable (not sure if our installer is adding their own fee within the £295)?

    Hi CW! It's been an interesting thread to follow and thanks for letting us know how it has worked out. I have to say you've done very well to get it all sorted in such a relative short space of time. The option posed above struck a chord with me as I did similar when we had our system installed four years ago, so not easy to compare then and now. But checking back through our paperwork, we had a Solaredge system with an HD Wave Inverter installed, I too had the option of extending the warranty, but to twenty years at a cost of 180 Euro's.
    I cannot find what period the original warranty was for but believe it may have been ten!

    Thanks, I certainly found it helpful reading through all the posts on here to educate myself on solar PV...and still learning.

    Our panels have a 15yr warranty, 10yr for the battery, but only 5 for the inverter which is why I am tempted to extend the warranty on that.

    The GivEnergy 5.0kWh hybrid inverter is relatively expensive so £295 for an extra 5 years warranty seems reasonable to me. I also have the feeling that GivEnergy are still going to be around in 10 years to honour the warranty.
