Who uses SAM? Why?System Advisor Model Lawmakers and Utilities to study how a policy would affect the economics of a typicalsystem 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 lowerthe 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 energy9

What’s unique about this platform?
Detailed Cash Flow Financial ModelsSystem Advisor ModelNo other tool provides detailed, time-based financial modelingacross multiple market sectors, including complex utility rates,combined with detailed performance modeling13
Detailed Battery ModelSystem Advisor ModelOnly publicly available tool with detailed battery model thataccounts for voltage characteristics, calendar and cycle degradation, etc Currently integrated with PV and “Generic System” modelAvailable on DC or AC side of PV systemMultiple automated dispatch strategies for different marketsBehind-the-meter or front-of-the-meter operation14
Advanced Analysis FeaturesSystem Advisor ModelBuilt-in parametric, stochastic, probability of exceedance(P50/P90), and scripting features enable complex questions to beanswered quickly and easily15
