Kristen Ardani of the National Renewable Energy Labs studies soft costs in US PV markets, and she recently joined us for a webinar to present her findings, in advance of a full report (to come in a few weeks). A pdf of the presentation is here (pdf) or watch the full recording in all its glory . .
Why are soft costs so important? Because these are areas where local policy makers can make a real difference in bringing down the total cost of installed systems. Solar modules trade on a global market (absent trade wars), and beyond contributing to total demand, there’s not a lot a local policymaker can do to affect module prices.
For example: labor for permitting, inspection, and interconnection adds about $0.22/W, on average, to the total cost of an installed solar system. And in some cases, as high at $.50/W. In contrast, similar costs are about $0.03 in Germany (see this report from LBNL). This is something that’s directly under local policymaker’s control.
We are looking hard at these finding to help guide our future activities here at Vote Solar…stay tuned for some new announcements soon.
In the mean time, NREL needs help collecting data for future editions of this analysis. They are asking solar companies to fill out surveys…residential here, and commercial here. It’s important — please help them out.
