A number of firms are now offering 'free' installation of PV Solar panels - where they own the panels and get the generation subsidary & money from any surplus power fed into the grid while the home owner benefits from free electricity (depending on power generated - up to approx 20% on usage) .
These contracts are for at least 25 years & stay with the house rather than the current home owner.
'Renting out' roof space is also starting to be an option for social housing builders but comes with a warning. see article from
'Inside Housing' here
Here is one report from the
BBCTV News report in Yorkshire

Remember before entering into any long term contract take professional & legal advice first.
