We consume around 4,500 kWh per year and recently bought an EV, so I'm not sure how much additional energy it will consume annually (mostly charging at work).

I recently received this quote from Soly for a system that would generate 4,781 kWh per year:

Aika 13 x 460W, Fox ESS EP11 (10.36 kWh), Fox ESS 6kW, Bird Protection – £9,763
