What is NREL's solar-plus-storage cost benchmarking work?

This work has grown to include cost models for solar-plus-storage systems. NREL's PV cost benchmarking work uses a bottom-up approach. First, analysts create a set of steps required for system installation.

What is a market approach to solar PV?

Market Approach Based on sales of comparable properties. Thousands of solar PV properties have been installed in the last two years, and market data are readily available. However, consideration must be given to ensuring that the prices of chosen comparables reflect only the value of eligible property.

How do market analysts evaluate the cost of PV systems?

Market analysts routinely monitor and report the average cost of PV systems and components, but more detail is needed to understand the impact of recent and future technology developments on cost. Consequently, benchmark systems in the utility-scale, commercial, and residential PV market sectors are evaluated each year.

What is NREL's PV cost benchmarking work?

NREL analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. This work has grown to include cost models for solar-plus-storage systems. NREL's PV cost benchmarking work uses a bottom-up approach.

How does a review team evaluate a solar PV cost basis?

The first step the review team takes to evaluate the claimed basis for solar photovoltaic (PV) properties is to compare the claimed basis to certain benchmarks. The benchmarks used by the review team for solar PV cost basis are predicated on an open-market, arm’s-length transaction

How does Seto calculate PV system cost?

Unlike most PV cost studies that report values solely in dollars per watt, SETO’s PV system cost benchmark reports values using intrinsic units for each component. For example, the cost of a mounting structure is given in dollars per square meter of modules supported by that structure.
