By this I mean disinterested from the commercial sales aspect
and also from the eco sales aspect......

Organisations like BRE. According to the hard numbers SAP 2005 if
I install a 2m2 solar panel on my home I can expect to save around
620kWh per year, say £20. If I let a solar panel salesman in, I
somehow doubt that he'd tell me not to waste my money ...
