Photovoltaic and energy storage continue to fall

Starting with the 2020 PV benchmark report, NREL began including PV-plus-storage and standalone energy storage costs in its annual reports.

A major component of total installed system costs is the cost of the PV modules. In a second report, Photovoltaic Module Technologies: 2020 Benchmark Costs and Technology.

You can download the system cost report and the module cost report. Learn more aboutNREL's solar system cost analysis. The 2021 benchmark report finds continued cost declines across residential, commercial, and industrial PV-plus-storage systems, with the greatest cost declines for utility-scale systems (up to a 12.3% reduction). Standalone storage systems also saw cost declines.

To accelerate the deployment of solar power, SETO has announced a goal to reduce the benchmark levelized cost of electricity (LCOE) generated by utility-scale photovoltaics (UPV) to 2¢/kWh by 2030. 3 In parallel, SETO is targeting a 2030 benchmark LCOE of 4¢/kWh for commercial PV, 4 5¢/kWh for residential PV, 5 and 5¢/kWh for concentrating .

The last decade has shown a sharp, though now steadying, decline in costs, driven largely by photovoltaic (PV) module efficiencies (now 19.5%, up from 19.2% in 2019) and hardware and inverter costs.

The National Renewable Energy Laboratory (NREL) has released its annual cost breakdown of installed solar photovoltaic (PV) and battery storage systems. U.S. Solar Photovoltaic System and Energy Storage Cost Benchmarks, With Minimum Sustainable Price Analysis: Q1 2023 details installed costs for PV and storage systems as of the first quarter .

As more intense storms ravage the country, and grid outages become more common, pairing solar with storage gives you a reliable source of backup power. "The costs on storage -- it's not cheap.

6 FAQs about [Photovoltaic and energy storage continue to fall]

Are soft costs affecting solar installation costs?

As in previous years, soft costs remain a large and persistent portion of installation costs, for both solar and storage systems, and especially for commercial and residential systems. “A significant portion of the cost declines over the past decade can be attributed to an 85% cost decline in module price.

How much does a PV system cost?

A decade ago, the module alone cost around $2.50 per watt, and now an entire utility-scale PV system costs around $1 per watt,” said NREL Senior Financial Analyst David Feldman. “With similar reductions in hardware costs for storage systems, PV and storage have become vastly more affordable energy resources across the nation.”

Are residential PV systems cheaper than last year?

Compared to last year's report, modeled market prices for installed residential PV systems were 15% lower this year.

Does NREL include PV-plus-storage and standalone energy storage costs?

Starting with the 2020 PV benchmark report, NREL began including PV-plus-storage and standalone energy storage costs in its annual reports.

What are the 2022 PV and energy storage benchmarks?

These benchmarks are bottom-up cost estimates of all aspects of PV and energy storage system installations. Many of the trends that characterized the 2022 benchmarks—including high and volatile component prices and competition for limited supplies—appeared to lessen in 2023.

Will solar PV & wind be more expensive in 2024?

Consequently, the average LCOE for utility-scale PV and wind could be 10-15% higher in 2024 than it was in 2020. Although their costs continue to exceed pre Covid-19 levels, solar PV and onshore wind remain the cheapest option for new electricity generation in most countries.
