How much does a solar PV system cost?The system costs range from $380 per kWh for those that can provide electricity for 4 hours to $895 per kWh for 30-minute systems. All right, so what will a 100-megawatt PV system with a 60-megawatt lithium-ion battery with 4 hours of storage cost?.
Should a PV system and a storage system be in the same place?Putting a PV system and a storage system in the same place, known as co-location, enables the two systems to share some hardware components, which can lower costs. Co-location can also reduce costs related to site preparation, land acquisition, labor for installation, permitting, interconnection, and developer overhead and profit.
Is energy storage a viable option for utility-scale solar energy systems?Energy storage has become an increasingly common component of utility-scale solarenergy systems in the United States. Much of NREL's analysis for this market segmentfocuses on the grid impacts of solar-plus-storage systems, though costs and benefitsare also frequently considered.
Why did PV system costs increase in Q2 2025?PV system costs increased in Q2 2025 following the Trump administration’s implementation of 10% baseline tariffs in April 2025. While a 90-day pause on reciprocal tariffs was announced, the baseline tariffs remained in effect and contributed to price increases across solar market segments.
What is NREL's PV cost benchmarking work?NREL analyzes the total costs associated with installing photovoltaic (PV) systemsfor 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.
Can PV and battery storage be co-located?When PV and battery storage are co-located, they can be connected by either a DC-coupled or an AC-coupled configuration. DC, or direct current, is what batteries use to store energy and how PV panels generate electricity. AC, or alternating current, is what the grid and appliances u
