When is the tool useful for users?
The tool is ideal for users during three phases of solar PV development: project concept validation, post site assessment, and post RFP solicitation.
- Project Concept Validation – the tool can be used to estimate potential project cash-flows using financial assumptions prior to completing a site assessment. If the user has a sense of the project size (system kW), estimate installation cost/watt ($/kWh), electric rate ($/kWh), user tax status, and the finance type (direct ownership, debt financing, PPA, or operating lease), the user can use the tool to model a project cash-flow projections up to 30 years.
- Post Site Assessment – using site information gained from a site assessment, a user will have have a higher level of confidence in the data the tool calculates. Using the estimated project size (system kW), estimate installation cost/watt ($/kWh), electric rate ($/kWh), the user tax status, and the type of financial type, the user can use the tool to model a project cash-flow projection for up to 30 years.
- Post RFP Solicitation – using the tool, a user can verify project solicitor information by entering the applicable input values and simulating the financial projection. The benefit of this is that the tool can be used to validate the project assumptions proposed by a potential developer.
