I don't agree with the parent commenter, but in some states/countries net metering is being turned around to having to pay a flat fee per kWh of solar generators. For example, my electric bill is around $160, I can net zero it out with 8kWh of solar costing me (installing it myself) about $8k total, but then if I get charged the $8 per kWh per month that is being proposed, I now pay $80/month to maintain a grid I rarely use as opposed to $0/month. Shifting my ROI from 4 -> 8 years. If you get solar installed with an installer, you would probably pay something like $20k for that same array, so your ROI goes from 10 -> 20 years, where your warranty might stop at 10 or 15 years. If you instead threw that $20k lump sum on the stock market and got 5% per year, you would match the amount you would have saved on solar. Edit: Math is hard, that's $64 a month and the numbers change slightly but the essence of what I'm saying still holds
