Yes, the calculation is based on $0.19/kWh charged by PG&E, with tiered rate, that cost does go up. So hosts will need to adjust the hourly prices depending on local cost and actual traffic. The $270 is from hosts with solar panels that have credits stored up. One user living in Santa Clara has 15000 kWhs saved up from almost a decade use of solar.

Thanks, that's a helpful example. This does sound like a great way for residential solar users to offload excess production, particularly if they can't tie it back to the grid directly (e.g., SDG&E's Net Energy Metering program [1]), or if the service rates can be higher than the grid-tie rates.

I guess that underscores that the napkin math gets pretty complicated and local use-cases can vary greatly. I'd be very interested in user-focused calculators that could help in guiding these napkin-math decisions the right hourly price to set locally, and/or whether the combo of residential-utility rates and local average public-charging prices makes it worth providing the service at all.

Yes, we have a ticket in the back-log to offer a feature that recommend pricing for the hosts. Taking into account public charging rates, utility rates, and traffic. The smart switch also has the purpose to distinguish charging vs just parking. So in some areas, we want to offer a separate rate for parking in the future.
