You have completely discounted the value of "feeling good about saving
the environment." While admittedly this is hard to quantify,
contentment is often a high-priced item.

For those for whom intent trumps results, solar panels would be a good
deal at twice the price.

Nobody can predict the future price of electricity. I can hardly think the
price would come down. So that is another imponderable.
