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.

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!

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
