Many NREL manufacturing cost analyses use a bottom-up modeling approach. The costs of materials, equipment, facilities, energy, and labor associated with each step in the production process are individually modeled. Input data for this analysis method are collected through primary interviews with PV manufacturers and. .
Since 2010, NREL has been conducting bottom-up manufacturing cost analysis for certain technologies—with new technologies added periodically—to provide insights into the factors that drive PV cost reductions over time. NREL also creates roadmaps that. .
