It is for a fraction of consumers- power companies and governments are well aware of that.

Exactly. Not a sustainable/scalable policy.

The point of my original post was that I’ve seen a much greater ROI on my own heatpump than solar, even though I don’t regret the solar installation. I wasn’t making any claims about sustainability/scalability of solar, just showing how it worked for me.

My comment was regarding net metering policy, not solar itself. Solar is great, and even better (for you) if you have net metering. But it’s not sustainable or scalable for utilities to keep offering net metering, and ultimately it creates wrong/distorted market signals: an incentive to generate more electricity when it’s abundant and to use more when it’s scarce.
