Just a heads up. Make sure you get both solar and powerwall at the same time if you don’t yet already have solar. I learned the hard way about the additional cost associated with replacing the ac inverter.
Here we’re mandated by the city to be connected to the grid at ~$10 a month, which (along with net metering) pretty much disincentives a powerwall.
- ChuckMcM 8y agoI was early to the solar thing, I put in a 5kW system in 2002[1] and we've replace one of the inverters when it failed with a single 6kW inverter. So any Powerwall install is going to be either in addition to that, or as part of a re-engineer to replace the panels with new panels that have more power for the same footprint. When you say 'mandated by the city' do you mean to say that you can't get a permit to put up solar unless you grid tie it? And if so does your power company allow for an even 'watts in vs watts out' scheme? [1] And yes it has paid for itself and is nominally cash flow positive at this point.
