That's a useful tool, thanks for linking that. How much did your hybrid system end up costing?

The total install was $12k. I also did another 1k in retrofits under the Greener Homes program, but I did the Greener Homes loan as well. I had to outlay the $13k up front, but then I got all of that back in a 10-year, 0% interest loan, plus $5600 in rebates on top ($5k for the heat pump, $600 for the furnace). The loan processing company debits my account $110 a month, which is low enough that it doesn't really sting.

I debated doing solar as well, since the Greener Homes loan goes up to $40k. Solar would gave easily soaked up the remaining $25k available in the loan. My roof isn't ideal for solar though, and I didn't want to triple the loan's monthly payments for a solar install that wouldn't have paid for itself over time.

TY. I'm considering solar as I picked up 2 pallets of panels for our farm, and I don't need all of them there. I assume there's all sort of permit issues in the city for that though, so I might just skip it.
