I was searching the web and solar panel installation seemed very costly. Anyone any views as to rough payback period on solar water heating system.
For me, ROI was going to be 10 years before any maintenance or replacement costs were included, so wasn't worth it.

We were also told seven years when quoted by two solar providers.
How did they work this out? Did they take note of your daily hot water requirements? Did they look at how you currently heat water and the insulation levels on the current system? Also, did they measure your roof angle and aspect?
If they didn't do all these things, then they are just providing you with a ball-park estimate, and these estimates are generally based on ideal conditions and usage patterns and don't take any maintenance costs into account.
Anybody got ballpark costs for supply and fit of soalr how water system.

Can you give us an example (meaning figures and calculations) where there is a 7 year payback?
