For what it may be worth, one local business put in a couple of solar powered EV chargers with NACS and CCS 1 connectors. With 10 400W solar panels (a 10' x 15' block) for each charger, on a bright sunny day, they will supply about 2kW average during sunlit hours. After about 4 weeks, they added a 230V AC connection to the charger to boost the charge speed to about 8 hours for a Tesla 57kWh battery (10 => 80%). After about 10 weeks, they modified the two charging stations so you needed a keycard since they had no physical lock mechanism on the charger or the parking lot and people were using them when the office was closed to charge personal EVs.
