How does solar-plus-storage affect energy systems?

Solar-plus-storage shifts some of the solar system's output to evening and night hours and provides other grid benefits. NREL employs a variety of analysis approaches to understand the factors that influence solar-plus-storage deployment and how solar-plus-storage will affect energy systems.

What is solar-plus-storage?

For solar-plus-storage—the pairing of solar photovoltaic (PV) and energy storage technologies—NREL researchers study and quantify the unique economic and grid benefits reaped by distributed and utility-scale systems. Much of NREL's current energy storage research is informing solar-plus-storage analysis.

Are solar-plus-storage projects economically viable?

Technology cost and utility rate structure are key drivers of economic viability of solar and storage systems. This paper explores the economics of solar-plus-storage projects for commercial-scale, behind-the-meter applications. It provides insight into the near-term and future solar-plus-storage market opportunities across the U.S.

Will the solar-plus-storage market grow?

At the lowest technology cost point modeled, solar-plus-storage is economical in 10 of the 17 locations and in all of the 16 building types modeled. This suggests that the solar-plus-storage market will grow significantly if solar and storage costs continue to decline as expected in the future.
