In this case, solar panels directly charge the vehicles, rather than the traditional net metering approach, which involves charging the vehicles with power from the local utility company, and then offsetting that by supplying the electricity generated by the solar panels back to the electricity grid.
So these vehicles draw electricity from the solar panel, not the electricity grid.
The solar panels generate up to 90 kW of electricity, which can power up to 59 homes, assuming that the homes consume an average of 1.53 kW of electricity hourly (this fluctuates, but this is what all those spikes and dips averages out to).
This could power up to 72 typical American homes which consume an average of 1.25 kW hourly, and use 900 kWh of electricity monthly.
