NLR’s solar technology cost analysis examines the technology costs and supply chain issues for solar photovoltaic (PV) technologies. This work informs research and development by identifying drivers of cost and competitiveness for solar technologies.
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are modeled and download the data and cost modeling program below.
The representative residential PV system (RPV) for 2024 has a rating of 8 kW dc (the sum of the system’s module ratings). Each module has an area (with frame) of 1.9 m 2 and a rated power of 400 watts, corresponding to an efficiency of 21.1%.
Each module has an area (with frame) of 1.9 m 2 and a rated power of 400 watts, corresponding to an efficiency of 21.1%. The monofacial modules were assembled in the United States in a plant producing 1.5 GW dc per year, using n-type crystalline silicon solar cells produced in Southeast Asia.
