EV power siphon?

For places like Hawaii, there is no payment for exporting energy back to the grid so self-consumption is the only option.

Here too. Well, no payment. The monthly bill gets credited for returned energy but only up to the total used in the period (net zero). That’s why I’d look into a hybrid SLA or AGM system if I ever go solar. I’d rather use more of what I produce, but still be able to store grid Joules for outages or needs during periods of low solar conversion.

Hawaii is $0 for export and 0 kWh credit. Hydro Quebec is a 2 year net metering kWh credit (no payment) so realistically it's only good if you size your PV system to ~115% offset to account for Solar PV degradation over the 25 years.

There is still the Canada Greener Homes grant which is $1,000 per kW of solar installed (max 5kW or $5,000) so you could build a small system and slowly add on extras (more solar, battery, whole home backup, etc.). It's probably a better value to replace the furnace with a heat pump and/or update the hot water tank to a hybrid heat pump hot water tank. I don't know what the price of natural gas is in QC.
 
I avail myself of Hydro Québec’s “Rate DT” (dual-energy rate), with an efficient (6.3 HSPF/14 SEER) air-coupled heat pump, and a (92 AFUE) gas furnace that kicks in at or below -12°C. The HP is 13 years old and the furnace is pushing 22, so likely both will be replaced in the reasonably near future. The 20 year old :eek: gas water heater was replaced with a Rheem hybrid heat pump unit last year; my gas bill went down by $20 a month, while the HPWH uses an average of 2.2 kWh a day. Yes, I’m looking at all the grants that are available.

Wow 2.2kWh a day! I have an AO Smith one and I think I'm in the 4kWh/day range. The real kWh hog is the Heat Recovery Ventilator (HRV) and that's probably closer to 10.8kWh/day.

I'm still using a gas furnace, but my home has already hit the US Department of Energy Zero Energy Building (net zero).
 
It’s so easy to get tempted by fancy gewgaws — I reeeeally want one of those German Passive House entrance doors — but there’s so much low-hanging fruit to grab in this terribly-built 1960s museum.
