I'm excited to see your 5-10 year prediction come true, and I think it will. However leasing will always make sense for some people. I have two 4 kW solar arrays on two separate houses, and I paid nothing for them. Instead of paying by electric bill to the utility, I now pay Real Good Solar (the company who leased them to me) a flat rate comparable to my average monthly rate calculated before I had the panels installed. The main incentive for me is that Real Goods Solar's bill increases ~2% per year, compared to the utility's average monthly increase of ~10%, so in 5-10 years my electric bill will be substantially cheaper than it would have been without the solar. The lease has a 20 year term, after which I own the system.
