> not reducing regulatory overhead. Actually, they do address this - it's one of their baked in assumptions about 'integrated roofing' (they refer to those costs as PII): "The roof replacement visionary pathway also benefits from savings in other cost categories. For example, the PII cost is reduced because we assume the PV permit cost declines to a standard $200 per system." Given the huge complexity of various city, county, and state regulations, I think it's highly unlikely that permitting costs would go down for a system that is integrated into the roofing material. And if I'm wrong, I can't see them going down significantly - permitting and inspection fees are an income stream for cities and counties, and they do't just reduce them because of a PDF from the NREL...
