Cases

8

A file contains one or more cases. Cases allow for comparison of projects

with different system configurations.locations, financing structures, etc.

A case consists of a complete set of

inputs and results. Tabs provide access to cases. The current case is indicated by a green

tab.

Financials

21

Choose market: Central ordistributed

For distributed market,choose financing type: Cash,loan, or third-party financing

Enter parameters Results displayed as metrics

(LCOE, NPV, IRR, etc.) and

annual cash flow summaryand detail

LCOE and other economicmetrics are very sensitive to

financial inputs!

Configuration Parabolic trough Dish-Stirling

Solar Field Layout (size, number and

arrangement of collectors, etc.) Heat transfer fluid properties

Collector and Receiver Dimensions and properties

Power Block / Engine

Capacity Efficiency coefficients

Storage (trough only) Capacity, heat loss parameters,

dispatch

Costs

Module and invertercosts in $/W or $/unit.

Operation andmaintenance (O&M)costs. Fixed annual cost ($/yr)

Fixed per rated capacity($/kW-dc) Variable per total annual

output ($/MWh-ac) Default values are

illustrative and notbased on actual

projects. Actual costs depend on

location, project type,market conditions
