    If it was me, I wouldn't want to pay £10,000 for only 13 panels (even fully installed and including inverter). If they're 420W then you're paying nearly £2/kWp I think?

    From personal experience I know getting actual quotes can be tricky at the moment but I think it’s worth getting one or two more to compare. And interrogate them on their proposals to make sure they’re tailoring things to your situation

    Neither is a particularly great deal. The project solar one is awful, ignore it.

    The second is better, but still not great, but that is a lot of battery.

    3300kWh a year is an average of around 10kWh a day. You'll very rarely use your full battery, only when you have a sunny day followed by no sun all for two days, and it will not be cost effective.

    Dropping down to 10kWh should save you at least £1500 and will make virtually no difference to how much you save. You'll get much better value just going for 5kW but if you want to over spec your system then it's your money.

    For reference someone was quoted £15,500 for 7.5Kw and 15kWh here:

    And I got a quote for 8kW and 13kWh for £14,000 at the start of the month.

    Thank you very much.
    Yes they have bought this out recently with 40 years warranty. 
    Sunpower are great but really expensive. If you're after quality alternatives, SolarWatt is made in Germany and has a 30 year warranty. Sharp 400W all black panels are made in the UK with a 25 year warranty. Hyundai 400W panels are made in Australia (and are affordable thanks our trade deal), also with a 25 year warranty. REC is the fifth and final quality solar manufacturer who have enjoyed high efficiency panels that are smaller in dimensions. 

    For inverters, I would only install Enphase or SolarEdge (with the 25 year warranty included as part of my quote). For optimizers, only SolarEdge or Tigo. 

    These brands are the only components  I would trust. Hyundai and Sharp panels are excellent value for money, which is why my installer prefers them paired with SolarEdge inverter + optimizers. All for < £6K!

    Given the really high Octopus Agile outgoing SEG tariff, I would argue against a battery for the foreseeable. Save the money upfront till energy prices crash (when was the last time that happened?). The consensus seems to be that your quote are both ridiculous - I would seek more quotes if I were you. 
    -  10 x 400w LG + 6 x 550W SHARP BiFacial Panels + SE 3680 HD Wave Inverter + SE Optimizers. SE London.
    -  Triple aspect. (22% ENE/ 33% SSE/ 45% WSW)
    -  Viessmann 200-W on Advanced Weather Comp. (the most efficient gas boiler sold)

    Feel free to DM me if I can help with any energy saving!

    That's including installation cost and it has been standard across all 3 quotes i have got now

    Unless you've got a very hard roof to work with then you've got three very expensive quotes. At retail prices each panel costs around £200 for expensive panels.

    You might be in the distant Highlands of Scotland, or have a unique roof, or 15 different sections of roof to install them in, or need optimisers on all your panels due to shading, all of which can make it more expensive, but the simplest answer is that you've gotten three bad quotes.

    Try to get some more.

    Thank you,

    Who was the quote provider?
    And what company battery and inverter are quoted for?

    Screwdriva is not a solar installer. He had a good experience with an installer called Light Renewables, who are cheap but others experiences have been mixed.
