6 What can yu d with SAM? System Advisr Mdel Mdel a variety f technlgies in a cnsistent platfrm Access high-quality perfrmance and ecnmic mdels develped by NREL, Sandia, and ther partners Calculate financial metrics such as LCOE, NPV, payback fr prjects in different markets Perfrm parametric and uncertainty analyses View and exprt mdeling results in a variety f ways Access extensive help dcumentatin, view tutrials and webinars 6

7 Wh uses SAM? Why? System Advisr Mdel Lawmakers and Utilities t study hw a plicy wuld affect the ecnmics f a typical system t analyze different types f utility rate structures fr renewables Develpers and Engineers t cmpare technlgies, sites, r cnfiguratins t estimate the Levelized Cst f Energy fr a system Researchers t examine hw an innvative cncept might be able t lwer the Levelized Cst f Energy t estimate the technical ptential f a technlgy in a regin Students t learn abut renewable energy t explre financing structures fr renewable energy 7

8 SAM Users System Advisr Mdel Over 65,000 registered users in 130+ cuntries SAM is started ~every 2 ½ minutes ( > 600 times per day) 90+ webinars with 113,346 views 8

10 Battery Mdel Designed primarily fr behind-the-meter analysis (residential and cmmercial scale systems) Lithium in and lead acid chemistries including submdels fr cell vltage, capacity, thermal, degradatin, and replacements Highly cnfigurable manual dispatch cntrller Integrated with PV system lifetime analysis t capture ecnmic effects f capacity degradatin and csts f replacement Incentives, cmplex utility tariff structures, and financing csts included in analysis. Validated with labratry measured test data fr tw systems. 10

20 Lifetime Analysis In this mde, PV system degradatin is (crrectly) applied t the DC utput f the PV mdules, and s can be used t assess inverter clipping levels as the system effective sizing rati changes in time. DC pwer AC pwer (30 years) When the system is new, much mre DC pwer is generated than inverter capacity, resulting in significant clipping. As the mdules degrade and prduce less pwer, clipping is reduced in the later years f the system 24
