6 FAQs about Photovoltaic surplus power storage

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.

What is solar photovoltaic (PV) energy & storage?

Solar photovoltaic (PV) energy and storage technologies are the ultimate, powerful combination for the goal of independent, self-serving power production and consumption throughout days, nights and bad weather.

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.

Is energy storage a viable option for utility-scale solar energy systems?

Energy storage has become an increasingly common component of utility-scale solar energy systems in the United States. Much of NREL's analysis for this market segment focuses on the grid impacts of solar-plus-storage systems, though costs and benefits are also frequently considered.

What is the value of a PV plus storage system?

The overall capacity credit of the PV plus storage system can be translated into a monetary value, often by using the cost of a proxy resource such as a peaking combustion turbine. For example, one estimate of the annualized financing and operations and maintenance (O&M) cost of a new combustion turbine in California is about $149/kW (CAISO 2017).

Can a solar energy storage system be installed in a commercial building?

Just as PV systems can be installed in small-to-medium-sized installations to serve residential and commercial buildings, so too can energy storage systems—often in the form of lithium-ion batteries.
