That might be the case but the fact is that these incentives exist and eligible home owners that don’t use them are in effect throwing money away. Also, it can be politically and technically expedient to provide incentives, even if it is not the theoretically most efficient use of that money. For example if it increases acceptance for renewables in the broader population or jump starts an industry (as it has in Germany).

You don't need to use tentative phrases like "That might be the case", or "even if it is not theoretically most efficient use of that money". As the page on statista.com states: >Rooftop solar photovoltaic installations on residential buildings and nuclear power have the highest unsubsidized levelized costs of energy generation in the United States. If not for federal and state subsidies, rooftop solar PV would come with a price tag between 117 and 282 U.S. dollars per megawatt hour. … https://www.statista.com/statistics/493797/estimated-levelized-cost-of-energy-generation-in-the-us-by-technology/ https://www.statista.com/statistics/493797/estimated-leveliz... It is understandable that anyone getting free money thinks it is good. But if the less well off people (renters, etc.) learn that they are paying more for power to subsidize wealthier residents (when that money could have gone a lot further if spent on other solar projects) - don't you think that might lower enthusiasm for government subsidizing the move away from fossil fuels? This sort of reverse Robin Hood policy hurts everyone in the long run.

  Places outside the U.S. exist, you know? PV would be cost effective here in Germany for residential buildings even without incentives, though most owners would probably build smaller installations. And there are plenty of countries without government incentives where people still build PV. As for the renters: many of them currently have decided to buy small plug in PV sets, since their installation has been allowed under German law recently. No incentives for those, either. And I’ll repeat myself: incentives can have valuable political goals that have nothing to do with cost effective buildout of solar. In Germany, these incentives have contributed massively to improving popular sentiment towards PV and acceptance of government subsidies for renewables generally.

    >...PV would be cost effective here in Germany for residential buildings even without incentives, though most owners would probably build smaller installations. I suspect the cost differences between ground based solar installed by a utility and consumer rooftop solar aren't really that different in Germany. Most of the cost of rooftop solar are the soft costs, with the bulk often being the labor costs for the work on the roof. The costs for the actual panels is very low these days. >...In Germany, these incentives have contributed massively to improving popular sentiment towards PV and acceptance of government subsidies for renewables generally. To repeat myself, I do understand that people like getting free money.
