* It's as cheap as it is for residential solar because of government subsidies. Ultimately a subsidy just means somebody else is paying for it, so this falls apart at scale when you're talking about something that everyone will use somewhat equally.
* I looked at residential solar and it looked to me like if I paid it off for 5 years at the rate that it saved me money, I would be further behind than if I had waited 5 years and solar panel prices continued to decrease. So why buy now? They decrease in value faster than they save money. It wouldn't have been a financially motivated decision.
* The solar company said they could eliminate my electricy bills if I bought solar, and they did a bunch of upgrades like improved insulation. The insulation had a much higher return on investment so I did that anyway - it's easier for me to simply need less energy than to replace all my energy sources (similar to a lot of environmental issues, IMO - we could overhaul recycling infrastructure, or I could just buy food that results in less non-compostable waste).
