Every single year I talk to companies and the cost has gone down, barely. I've been told every year for the last 20 years that technology is getting so much better. The panels are so much more efficient, cost less, the state and federal govt have tax breaks, blah blah, blah. The Chinese have found a way to produce them this way and that way, "Oh you just wait, its really going to be affordable in the next few years!"
No, its still not affordable. If it were, like OP said you would see them on every house in your neighborhood.
I've wanted to put solar on my house for very long time and every year its the same thing. "Finance a $15,000 loan and in ten years you'll have free electricity!!"
I would say anybody who's rational, informed and interested looking at that would 100% of the time its not worth it.
Solar module prices over the past 20 years went from $2/watt to $.3/watt. Installed prices are a little more, going from maybe $6/watt to ~ $3/watt. I paid about $3.5/watt installed in Berkeley 3 years ago, a place not known for affordability. In the meantime, (average in the US) electricity rates went from ~$.10/kW to about $.16/kW. If over that period, your payback period has remained constant, you must have dramatically (like 20x ) reduced your power usage. Congratulations!
