Solar panel on the roof  
Just got sales guy from a1asolar.com.
He's selling solar panels to our roof.

The cost is about $20K...$30K depending on our electricity needs.
Zero money down, 2.99% financing for 10 years.
30% IRS tax credit.

The homeowner soon discovers their alleged energy cost savings are nowhere near that which was promised. If the homeowner refuses to pay on what is now an upside-down lease, they learn for the first time that the solar profiteer placed a lien on their home – a lien that impairs the customer’s ability to sell their home and that forces them to continue to pay under a bad contract at fear and risk of potential foreclosure or other legal action by the new holder of the lease.

Besides, energy prices (oil and gas) went down significantly, so it makes solar panels less attractive.

What do you think: should I install solar panel on the roof of my house or not?

Update 2:
Vlad Turchenko recommends (on Facebook) this solar panel:

Solar panels can be profitable only in massively government-sponsored cases. So, definitely not. :)

1) That "solar on the roof" project is massively sponsored by the government anyway.

2) The cost of solar panes is going down over the years.
The questions is more like "are we there yet?".
My guess is that we are not there yet, but it's hard to be sure.

1) With liens on property? Their side is sponsored, not yours.

If their side is sponsored, they can sell it cheaper, right?

What's your point about "liens on property"?
Yes, I assume they may want to use my house as a collateral for the loan.
May be I should refuse that and let them use solar panels as a collateral.

I would not go there. I checked, does not makes sense to me.

What was the difference in price between regular grid electricity and cost of electricity from these solar panels on the top of your roof?

What year was that when you checked?
ex_juan_gan on April 7th, 2015 11:23 pm (UTC)
It was last year. I figured it would take over 20 years to pay off, so what's the point. By that time it will all a) fall apart, b) make no sense, like ancient huge satellite dishes.

Are you going to wait for few more years until solar panel prices fall down and then consider installing it again?
ex_juan_gan on April 8th, 2015 12:42 am (UTC)
I will check out in a couple of years.

I abandoned the idea a couple of years ago. Now there are less (tax) incentives from my state, so it is even less feasible project. The show stopper was installer's request to remove some trees around my house, some of the were on neighbour's land. Let them go f. themselves.
Dennis Gorelikdennisgorelik on April 8th, 2015 02:45 am (UTC)
I'm in Florida (not in New Jersey, like you) and there are no trees covering roof of my house.
There were also 2 more years of falling solar panel prices.
So it's not as obvious as in your case.

Still I'd rather to err on conservative side with innovations like that and let my neighbors test them out.

I was also researching the technology a bit. It was said (in an article) that current tech is quite inefficient. There are some experiments with titanium oxide that may produce better/more efficient panels in near future, that are capable to harvest good amount of energy when the angle for solar rays is no exactly 90 degrees to the panel surface. Then it would be possible to get much more energy from the same sq footage. My concern for this was that I would pay up front cost (or get into lease / loan whatever) for a technology project where quite quick and revolutionary progress is possible. Then I would be left with outdated inefficient panels, that would not be worth using comparing to the new stuff. Something like that.
Dennis Gorelikdennisgorelik on April 8th, 2015 03:31 am (UTC)
Yes, being left with outdated stuff is something I concerned with too.
Another possibility is that industrial solar panels could be more efficient.
For example, they may follow sun movements and are easier to install at scale.
That would bring price of electricity down and make solar panel installation on my roof meaningless.

When it starts making economic sense I will definitely be in.
