It just went up 66% on August 1 from $6.85 to $11.40! I don't mind paying the higher fee since I could never rent a 4 MWh battery to store energy collected in summer for use in the wintertime for anywhere near that price.
The last three big changes to our energy consumption were:
~3 years ago: Added LEAF = +2 MWh
~2 years ago: Replaced water heater with a heat-pump water heater = -3 MWh
~0.5 years ago: Added PV production = -4.5 MWh
With these changes, I am hopeful that we will be energy neutral for our nearly-all-electric home (cooktop is propane). It may not quite work out this winter because the new PV was installed a bit too late to save up as much as we likely will need. As such, we may need to pay a couple of power bills in February and March. But hopefully future winters will work out with no additional bills.

I feel the same way! Unlike some people's experiences with early-generation PV systems or early-generation electric vehicles, nearly everyone which recent-generation PV systems is pleased with the purchase. I think they have really come into their own.
Still, the adoption rate for PV is quite a bit lower than I would expect. A self-installed grid-tied system works out to around $0.05/kWh these days, assuming a decently-pointed roof with little or no shading. That's less than half the going rate for electricity here.
