Soft costs include intangible costs such as permitting, taxes, customer acquisition costs, etc.įigure 1. Fiedman, et al, “Benchmarking Non-hardware BoS Costs for US PV Systems, Using a Bottoms-Up Approach and Installer Survey,” National Renewable Energy Laboratory, Second Edition, December 2013.įigure 1 illustrates the relationship between soft and hard costs, and breaks down hard costs into its components. According to SEIA, while hard costs have come down dramatically over the last decade, soft costs have remained largely constant. O&M costs refer to costs that are associated with running and maintaining the system. 1809 Posts 22 Topics Last post by bean in Re: So No Reason to Hold. ![]() Incentives and Policies that Benefit Solar Energy These can include fuel, repairs, and operation personnel.
