When you create a new case or file, SAM populates inputs with default values to help you get started with your analysis. So, if you create a case for a utility-scale photovoltaic project with a single owner, SAM populates the inputs on the Financing and System Costs pages with values that are reasonable for a typical PV project for power generation in the United States. The default values are just a starting point: As you develop and refine your analysis, you should change the inputs to values that are appropriate for your analysis scenario.
The default costs for SAM's photovoltaic model are from the NREL Annual Technology Baseline (ATB).
