That's pricy.

You're looking at a huge system, which I applaud, but the price per kWp and battery should be dropping as you get larger.  The optimisers boost your costs but even so it seems high.

At retail prices the panels are £5k. The optimisers £1.3k, the inverter £1.6k, the battery  is a comical £7k and the Zappi £0.75k. For a total of roughly £15.6k.

The racking and cables aren't going to come to £3k and that's all at retail prices and mostly including VAT which wouldn't be paid.
