I agree with Paul's comments- Matt, can you make issues for those future improvements and assign to patch 1 for now? Thanks!
new terrain inputs, bottom 2 defaults not read in)
Revise description of load data time convention. Remove O&M cost content from Installation Costs topics. Add ETES topics and fix broken help links. Fix typo on battery storage FOM "BTM" insteasd of "FOM" Wind resource files can now be .csv in addition to .srw Revise capacity factor descriptions for PV and Battery storage configs, #905 Wave resource instructions for converting from time series to JPD, #892 Revise PV land area calculations to account for GCR and tilt angle, #928 Add pvlib column headings to SAM CSV format description, NREL/ssc#754 Revised Operating Cost input pages Check for "annual energy" vs new "electricity to grid". Change "battery autonomy" to "autonomy". Revise power tower heliostat field to better explain how check box vs button works. Add note for degradation by year that Year 1 value should be zero, #755 Remove debt from payback period description. Also remove detailed cash flow descriptions and replace with mention of send-to-Excel with equations and spreadsheets on website. See Amir Nashed email 1/19/21 and https://sam.nrel.gov/forum/forum-general/1052 Revise Electricity Purchases page to be specific for FOM projects New LCOS metrics: #529 Electricity rates revisions from Brian. Reporting of electricity bill in time series results, see NREL/ssc#652 New parametrics features Parametrics description of how to work with SchedNumeric variables like PPA price. See Brian email 7/21/2021 Update Heliostat Field per #717 New PV slope inputs on System Design page. See #742, NREL/ssc#648 New "Limit debt fraction" Input on Financial Parameters page for PPA models New ETES model. Fix outdated description of NSRDB in Location and Resource topic UDPC updates from Ty, see Revisions 2021 folder. Also post new PDF version of Ty and Matt's description under "CSP Power Cycle Models" on SAM website https://sam.nrel.gov/concentrating-solar-power/csp-publications.html, https://sam.nrel.gov/images/web_page_files/Neises-DRAFT-user-defined-power-cycle-v3-2018.pdf Fix excess generation descriptions in help: https://sam.nrel.gov/forum/forum-general/3485. Also maybe change "Excess generation" to "Excess generation for net metering" or similar. Note for URDB download that demand ratchet data in URDB is unreliable, so check with data sheet. Demand charges with ratcheting lookback months. See Revision Notes mirletz-RE Adding billing demand lookback to SAM.msg, see [[F:\OneDrive\SAM\Utility Rates\Demand Ratchets\Initial Tests May 2021]] Update pv smoothing per Steve's email 12/9/2021 "pv smoothing question" Improve description of FOM automated dispatch. See https://sam.nrel.gov/forum/forum-general/3681 Revise electricity rates page Consolidate weekday/weekend schedule descriptions. SWH remove old hot water draw import instructions. Revise electricity purchases PPA price option not available with Specify IRR target, and purchases treated as tax-deductible operating expense. Move electricity purchases page to from Battery section to Electricity Rates and Load section Edit Lifetime Data add note about pasting data from Excel: Thousands comma separator causes paste not to work correctly, e.g, 1,000 is pasted as 1.
-New terrain tilt angle and terrain azimuth (measured East of North) inputs for subarrays
-Only enabled for 1-axis tracking for this release
-If backtracking enabled, backtracking angle influenced by terrain inputs
-If linear shading is enabled, shadeFraction accounts for terrain input effects on beam self-shading
