The costs for non-grid solar (like residential) seems to basically be labor. The panels are generally made overseas, so funding/sponsoring that just exacerbates the trade imbalance / domestic solar industry, but subsidizing the labor is a form of "local spending" that will improve local economies and make the jobs better. Since IMO residential solar should be a significant aspect of the USA's domestic energy policy, because it will help offset the grid impact of BEVs and make communities more resilient to disasters (and rapacious policy like the Enron days), I'm in favor of heavy subsidies to home solar.
