for info - Which Oct says PV panels installed after Aug 2012, costing £7,500 could net only £6,462 profit after 20 yrs - £1,500 less than a savings a/c paying 4%, UNLESS pv earnings are invested in cash isa at 4% over 20 yrs when net profits = £13,358.
Apparently Which Money Oct 2012 has more details.
Aren't all such calculations - by Which?, salesmen, the Govt, etc - irrelevant unless you expect to stay in your house for at least 20 (or whatever) years.
