Thank you all for your responses. In France, solar power has turned into the replacement windows/conservatory pressure selling that the UK suffered from in the '90's. '1€ to install and then become wealthy selling all your electricity back to the grid' type of thing. I've just given up trying to find a straightforward installer. That's why I wondered if there was a stand-alone 'off the shelf' system of solar/battery/charger just for EV's as it seems a logical thing to do. However, maybe the costs just aren't sensible yet.
The energy price hikes last year gave rise to big increases in the cost of panels and batteries as supply was overwhelmed by demand.
The utopia here is to run your house, charge car and batteries and then run on battery at night for no cost. In winter, when solar is poor, using off-peak grid instead of, or to supplement solar. Solar car charging only isn’t a thing unless you have a lot of panels and some aren’t permitted to export.
Solar edge do have a battery system with an inbuilt car charger and of course they do panels and inverters too.
@Yachtsman had such an installation though he has had a lot of problems with all of the components not doing what they should when they should.
You are in different environment and French installers play a different game at present. How you approach the right solution depends upon the amount of sun you get during the year, whether your panels will be shaded or not and what the daytime/nightime electricity costs are.
You can see what I have in my signature. from October to March, I buy off peak every day to top up cars and batteries.
The rest of the time I buy about 1KWh per week which is just the result of the Powerwalls balancing against the grid. I have a surplus most days after charging everything.
A Zappi is probably the best solar charger going at the moment.
Your best starting point, is to get a calculation of how much you could generate and work from there to suit your needs. Also consider power cuts if you get them. Solar panels in the U.K. shut down during power cuts for safety unless you have a Powerwall or the latest Givenergy batteries.
I’ve just passed the 10k miles mark on my model 3. fuel costs to date are just £97 because of solar
