Here are some trivial calculations. $10000 of current solar panels will give you $10000 worth of power after 20 years. $10000 invested at 6%pa for 20 years will give you $32000. $10000 of $1/watt solar panels will give you $80000 worth of power after 20 years.

This is the point. If the panels are cheaper then people might invest in a larger system and be no more out of pocket. Therefore more renewable energy, therefore better for the planet. If the panels stay costly then people are less likely to invest in them - not everyone has sufficient money that they can hand money over with little expectation of financial return - the costs of individual PV systems are not trivial to everybody. I do however agree that the costs may be looked on as trivial for society as a whole if our leaders choose not to invest in renewables and instead "invest" in more freeways or other non sustainable investment and the climate change impacts as predicted. Government definitely can afford it, even if a significant proportion of individuals can't. If panels remain expensive then in terms of what is best for the planet it many be better for people to invest in Green Power and, if they have additional investment money, to invest directly in medium to large scale renewables, built by third parties, where there are more kWh generated for each dollar invested. In my opinion this would be "doing the right thing". at most it will have a short lintel which could be moved up just below the ceiling or even above.
