Where I live it is a) very sunny almost all year round and b) very common to have PVs on your roof. I currently have 5KWH installed on my roof, I have a Nissan Leaf which I charge every day whilst I am working for home and I've paid 70euros total for electricity in the last 2 months, whilst running the underfloor heating constantly.
