The numbers are in my original post.

We got 7.6kw installed for $13,000 CAD. I ordered everything myself, had a local installer do it on his weekend, paid an electrician $180 to pull permits and actually wire it into the main house panel. All inspections complete and legal. $5000 grant $8000 interest free loan.

The system makes 7.76Mwh per calendar year. Electricity here is 0.13/kwh, and already pre-approved go up minimum 5% per year. It just went up 6% for 2026, 16% for those out of town.

So the system makes right on $1000 of power every year that I don’t have to buy. We’ll put that onto the loan for 7-8 years , then get at least $1000 a year for the 20 or so years remaining of the system life.

I’m nothing out of pocket, and I’m just putting the same into the loan for 7-8 years that I would have paid in electricity anyway, so no difference.

No brainer.

My house now uses net zero energy ( disconnected natural gas entirely)

I have no idea where you’re getting a quote for so high. Even the highest I got was ~$20k, and that was over 18 months ago.

Those numbers are pretty low for Canada (well done on getting a good deal) - though it sounds like you are doing all the work yourself so thats sweat equity and the difference is the margins / work that installers put into the equation.

I don't think what you are providing as an example is what most people are doing. Most people are going through residential installers and not doing all the effort you did to bring down costs.

I commend your effort but it isn't what most people would be doing or paying for and represent otherwise isn't quite honest for people looking to get numbers for their own install.
