I’ve just double checked the Eon site, they have a cost calculator, a six panel 2.3kw system is £4000 or £7300 with a battery. The maths on their site doesn’t seem quite right as it £4000 for 6 or £6200 for 8 panels, seems like they are over charging for additional panels. There’s no way it costs an extra £2200 for 2 panels.
