Am I being ripped off?

Hello everyone,

I am based in the UK and I wanted some advice if possible. I have a large property with electricity usage hitting 9,000 kWH annually. I have had the property surveyed and a local solar panel company has advised I should fit 69 of the 445 watt panels to the property (27,143 kWh per year according to the estimate they have provided) with a 11.92 kWh battery storage.

​

They are quoting £25k for all this including installation. What do you guys think? Is this a complete overkill and will I ever get my money back on this investment? Are they charging too much for a supply and install of this size?

I mentioned I never wanted to pay for electricity again but at the same time I would eventually like to get a return on this investment. I’m not sure whether I should just proceed with this quote if it’s a good deal, get another quote for reduced panels or just shelf the idea and pay for electricity from the 5% interest I would earn in the bank with the same £25k amount etc.

Apparently I will be earning good amounts of money from Octopus by selling back to the grid. But I am just concerned if the money earnt and saves will still get me a return back of at least my initial £25k?

Thanking everyone in advance for your thoughts.
