Re: In terms of watts per dollar...

I thought your financial and efficiency numbers seemed a bit iffy, vague and dismissive of the FiT income. It seems your usage is atypical, as most people are grid connected and therefore interested in the additional income and savings to be made.
I personally have both thermal and PV and my numbers say that if the scheme payments supported a bigger roof array at the expense of the solar thermal then that is what I would do.
The thought of giving the excess generation away to your neighbours is commendable however for most people it’s the payback time that matters.
