 Hi Robyn,

 Are these the things that look like a black corrugated iron roof,
 and that get stupidly hot in even the mildest heat .. ?  I've seen
 these, and am expect I'll head down that path for my own hot
 water system.  Do you have some pointers to manufacturer or retail
 pages of the 2am-peak style systems that you're referring to?

 As you say, storage of energy becomes the big one, and this is
 why solar will always be a component of a green energy provisioning
 system .. until room temperature superconductors are invented,
 that is.

 Jedd.
