Producing panels and charging circuitry has a carbon footprint. So does installing them. It's going to take a long, long time for car-mounted panels to offset that footprint, and even longer for the cost. On top of that there's costs associated with leaving your car exposed to sun all day which you have to factor in for everyone except drivers who have no choice but to do so.
