Electric cars.

I would never charge directly from the solar panels anyway - not just for the reason you say - but the car is at work during the day 5 days a week!

I haven't had the solar long, so no idea what excess generation I'll have in summer, but even then selling to the grid will earn me more per k/w than I pay for EV charging by OVO. So doesn't make sense financially to use it myself.
I think the feed in tariff is 14p k/w or there about and I pay 7p for the EV per k/w.
Add in the extra stress and full discharge cycles on the battery - which will shorten its life - I just can't see a case for ever doing so

Now I have solar and a battery, but I went the other way and had the charger installed independently of the battery and solar
The solar panels cope with my day time demand and charge the battery (if it's not cloudy) and my house uses the battery in the evening and overnight. OVO controls the car charging via direct connection to the grid and I only pay 7p k/w for EV charging. So why would I waste my solar battery capacity charging the car and then using leccy at 24p k/w for the house?

I do things the same way, makes the most sense with my setup and needs.
