Not sure what you mean by needing an EV to use the energy. With an A/C system you can heat and cool the house with electricity efficiently. Since that works even if your car is away with you at work the battery size is reduced making that load a better business case. The same for heating water, which is a cheap battery in itself.
If anything EVs seem particularly unsuited for home solar because the solar panels should instead be wherever the car spends its day so the car battery can be charged directly instead of needing another battery to buffer the energy for it.
- guerby 6y agoIn France you don't need heating/cooling for most of the year with a moderately insulated house. Thats's why electric car charging changes the equation. And about no heating/cooling at all with a Passive House :). I agree about charging during the day when the sun shine is way better but it's under the control of your employer which may or may not provide chargers, and might not install solar PV at all for various reasons. PV and battery at home, you can do it right now.
