I am looking at building a solar water heating system for domestic hot

does anyone in this group have any good links to panel construction and
control systems?

Also has anyone (silly question!) done it and was it worth it.

I can but a system for about 2.5K but I would like to try to do some or all
of it myself.

http://www.sustainable-girton.org.uk/pv/ gives a few figures on a new PV
installation, which in *February* produced 2/3 of the owner's
consumption. On good days it made 3.3Kw.

If you contact me privately I could get more details for you but you
should be able to work out the installer's website from the pictures.
