Who uses SAM? Why?
• Lawmakers and Utilities… to study how a policy would affect the economics of a typical
system
… to analyze different types of utility rate structures for renewables
• Developers and Engineers… to compare technologies, sites, or configurations
… to estimate the Levelized Cost of Energy for a system
• Researchers… to examine how an innovative concept might be able to lower
the Levelized Cost of Energy
… to estimate the technical potential of a technology in a region
• Students… to learn about renewable energy
… to explore financing structures for renewable energy
