NREL analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. This work has grown to include cost models for solar-plus. . U.S. Solar Photovoltaic System and Energy Storage Cost Benchmarks, With Minimum Sustainable Price Analysis: Q1 2023, NREL Technical. . Watch this video tutorial to learn how NREL analysts use a bottom-up methodology to model all system and project development costs. 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. [pdf]
Solar storage systems store the excess energy produced by solar panels, making it available for use when sunlight is minimal or unavailable. These systems are commonly used in residential, commercial, industrial, and utility-scale solar installations. This section will discuss each application of solar energy storage systems in detail.
The benchmarks in this report are bottom-up cost estimates of all major inputs to PV and energy storage system installations. Bottom-up costs are based on national averages and do not necessarily represent typical costs in all local markets.
This translates to a range of $2.06– $12.37/kW/year, and a benchmark value of $3.44/kW/yr. for a 200-kW commercial rooftop system and $1.17–$7.02/kW/year, and a benchmark value of $1.95/kW/yr. for a 100 MW utility-scale single-axis tracking system.
One of the most popular and frequently used methods for storing solar energy is battery-based storage systems. These systems store electricity in batteries during periods of excess solar energy production and discharge the stored power when it is needed. Lithium-ion batteries are the most commonly used battery storage system for solar energy.
This section covers the main types of solar energy storage systems, including battery-based, thermal, mechanical, and hydrogen-based storage systems. One of the most popular and frequently used methods for storing solar energy is battery-based storage systems.
In summary, selecting the right solar energy storage system requires careful evaluation of factors such as capacity and power ratings, round-trip efficiency, storage duration, life cycle and degradation, cost and financial considerations, and environmental impact and safety concerns.
