I know of at least 2 guys who have them and have disconnected them from the grid... Not sure why, but they did.

I have read that panels have a life of 15-20 years. Good luck.
When I researched it 10 years ago, I found the same thing, and around here, hail storms would probably make it remain true, today. But in talking to people who live in less violent climates, they tell me the life expectancy of the panels has also gotten better.
I don't know if it pays to install solar panels or not (here in Centex, probably not) but I think it is worth looking into again.
I don't mind being called far right.
I have been right so far.

ROI time is dependent entirely on what the electric company will pay you for excess power generation and how much excess power you generate. If you only install enough panels to power 60% of your homes' electricity usage, it will obviously take longer than if you install enough to generate 90% of your usage. Some power companies charge more for daytime power usage as well, presumably to stick it to businesses that operate during peak usage times. Most electric companies here use "net metering", meaning your bill is the usage from the grid minus the power you generate, and since solar panels obviously don't work at night, you're using 100% from the grid at night unless you're using battery storage banks, which is a whole other ball of wax and an incredibly large chunk of change added to the installation costs.
I had investigated getting solar panels installed, but it would have taken me 17+ years to recoup the costs (in ideal weather conditions for that long), and I'm not sure I'll still be in this house for that long. Bartlett electric is pretty cheap, but that also meant they wouldn't pay me much for excess power I generated, hence the long ROI.
http://pvwatts.nrel.gov has a nice calculator to help determine energy creation, annual savings, etc. You'll need to know how much your power company will pay for power, how many panels and watts, the angle/pitch of your roof, etc. to use it. For example, 24 270-watt panels (6.48 kilowatts) in our area would generate ~9,795 kilowatt hours a year. At the time I was looking into it, Bartlett was paying $0.026 kWh, and I would have an excess credit of $254 a YEAR. If my average bill was $150/mo , I'd save $1,800 in utility bills plus $254 every YEAR. If my system cost $20,000 to install, it would take ~10 years to recoup the costs, not counting any income tax credits or deductions. Actually, I think the system I was looking to install was closer to $26k, and that was WITHOUT battery banks.

That just reinforces what was said earlier. Solar is not a good investment unless you plan to live in the home in excess of about 20 years.

Even then I'm not so sure it would be that good of an investment. Your roof would need to be totally replaced before 20 years, and the extra labor to remove and reinstall these panels would definitely add another couple $$ to the
cost.

I asked why he hadn't gotten 35 year shingles put on before he decided to install the panels. He just kind of stared back at me. It's all finished now, doesn't look bad. It's not for us, LED light bulbs is a far as it goes. I have driven a couple of Tesla's and they aren't all that. I will say the Hyundai Sonata Hybrid and the Honda Accord hybrid are nice.

Well, there are some folks who are eco conscious who do not care if an eco friendly investment saves them money or not...
All in all, eventually everyone will have to come to some sort of epiphany where power is concerned. Fossil fuels will only last so long.
Just the thought of that makes a car guy like me glad I will probably be long gone before that happens.

I was seriously looking at an electric car for running to and from work and all over the place, local. The Tesla's are good for 285-350 miles in a day, unless you get a Tesla 3, the others are 75k. The Nissan Leaf only good for around 100 miles, Honda isn't out yet, the BMW is muy expensive and the Chevy Volt is too plastic. The outlay vs the recoup is the issue of course.
