Two reports published by the US Energy Department’s National Renewable Energy Laboratory (NREL) show that soft costs — such as financing and other non-hardware costs — now make up the largest section of solar installation costs, coming in at 64% of the total price for residential solar energy systems.
The two reports — “Benchmarking Non-Hardware Balance-of-System (Soft) Costs for U.S. Photovoltaic Systems, Using a Bottom-up Approach and Installer Survey – Second Edition
” and “Financing, Overhead, and Profit: An In-depth Discussion of Costs Associated with Third-party Financing of Residential and Commercial Photovoltaic Systems” — combine to show just how soft costs are becoming an increasingly more important part of solar installations.
“The two new reports, along with previous reports, provide a comprehensive look at the full cost of installing solar, while delineating and quantifying the various contributors to that final cost,” NREL analyst Barry Friedman said.
The first report showed that in the first half of 2012 soft costs represented the majority of all costs — 64% of the total price for a residential system, up from 50% as identified in a previous report conducted in 2012, and similarly high percentages for small and larger commercial installations.
Residential soft cost categories for the first (2010 data) and second (2012 data) editions of the benchmarking study. For the first edition of the benchmarking study, 2010 “all other soft costs” had not been differentiated. For the second edition, we quantified five sub-categories within this broader category.
The second report focused on the five sub-categories identified in the previous report only as ‘other soft costs’ — namely, transaction costs, indirect corporate costs, installer/developer profit, supply chain costs, and sales tax.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
