Beware the terms of the contractors providing the service, I have heard reports of people being unable to sell their houses, because the contacting company have a claim to your roof (or some such stuff).
My main objection to solar panels on the roof is that they look hideous and you have to live to be about 150 to recoup the cost.:dunno:
(or both of those urban myths?)
That refers to the 'we fit and retain ownership and grab the dosh they generate' schemes
If you have panels fitted and pay for them your self, solar panels on a house puts the value of the property UP ( though by only a very small amount, a bit like double glazing )
We had ours fitted back in the days before they got mean with the unit values.. We currently get 46p per unit generated plus a percentage of electric used paid for
Of course, the downside was we paid through the nose for the system ( ?10,300 ) because, as mentioned, it was done way back...
We have had it in for about 5 years now.. We average ?400 per quarter from them ( 2kw system ) but our house could not be better placed as it is south facing.
We fully expect the system to have paid for its self in about 2 to 3 years, after which time ( for the next 17 years ) it will all be profit
Would I recommend having them fitted ? Yes, absolutely
