The National Renewable Energy Laboratory has rolled out a new benchmark metric called the “minimum sustainable price” in its 2022 PV solar and energy storage price analysis to better track long-term trends.
NREL’s annual solar and energy storage report has published estimates of national average cash prices for various classes of solar systems since 2010. This year’s report includes the new benchmark to compare long-term solar and storage cost trends to current deviations from the trend caused by inflation, policy and supply chain conditions.
While short-term price shifts can be difficult to predict, the minimum sustainable price benchmark should help to inform policy actions and decisions based on longer time horizons, according to the report’s authors.
