Nobody said that you have to use your home or work solar. If you fill up part of your car using some fast charger network (which would still be solar powered), it would still work.

Moreover, even if we take the top 25% percent of commute distances (which is >40km per day), that still leaves you with 10 days until you have to recharge. If you recharge every weekend, you still have plenty of battery capacity for your needs outside of sun hours (you likely will need only 1-2 kWh per day anyway).
