PV O&M Cost Model •  Title: PV O&M Cost Model •  ObjecFve: es0mate cost to deliver a PV O&M program

considering system configura0on and environmental condi0ons. This is needed for financial prospectus and to inform O&M decisions.

•  Team: NREL; SunSpec Alliance; Sandia •  Status (FY 16 Accomplishments):

o  Spreadsheet Prototype: –  Annual O&M Cost, –  Net Present Value, –  Reserve Account, –  specific to PV project, size, type, and several environmental condi0ons.

Consider an example with 2 inverters… •  Reserve Account sufficient to replace NEITHER of the two inverters:

Reserve Account: $0 P1P2 = P^N=(0.908)^2=0.824 (you get this level of confidence for free)

•  Reserve Account sufficient to replace EITHER ONE of the two inverters: Reserve Account=$10,000 P1P2 + P1Q2 + P2Q1 = 0.824+(0.908*0.092)* 2 =0.991

•  Reserve Account sufficient to replace BOTH of the inverters: Reserve Account= $20,000 P1P2 + P1Q2 + P2Q1 + Q1Q2 =0.666+0.300+ (0.092)^2=1.00

•  The cost model is coded such that the desired confidence that the reserve account will be sufficient is an input, with a default of 0.95, and the calculaFon returns the required amount of Reserve Account

CalculaFon of Reserve Account •  Reserve Account

Annual Amount in reserve = N*(Cparts+ClaborH)*R^(P/(1-‐P)

•  Also modified by: o  Within analysis period? o  Within warranty period?...type of warranty? o  Fixed interval or Weibull distribu0on? o  Yearly infla0on of costs.

•  This is done for each measure in the PV O&M Cost Model (PV module replacement, inverter replacement…all) and added up to calculate the total amount in the Reserve Account for each year of the Analysis Period.
