1.1 kW array, draped over the car is going to produce more like 0.7kW at best and probably less due to clouds and sub optimal angles. Good EV efficiency is like 3mi/kWh and let’s assume you get 8 good hours of sun, which may be generous depending on local weather and time of year. I think you’re only going to see about 16 miles of range added per day.
I don’t buy the “negligible” effect to air resistance and lower speeds. There are just too many factors.
So I guess if you commute less than 16 miles round trip, and you can easily remove it when going on longer, high-speed trips it might solve your lack of outlet. But I stand by the fact that if you can’t charge either at home or at work, electric may not suit your needs. I’m not a hater, both my wife and I drive EVs, just realistically they don’t suit everyone.
