In the first quarter of 2023, the benchmark installation cost per watt for residential solar across the U.S. dropped by 50 cents compared to Q1 2022, while utility-scale solar’s average installation cost per watt rose by 9 cents, the National Renewable Energy Laboratory found in a new report.
NREL also said in a Tuesday release that the trends of “high and volatile component prices” and competition for limited supplies appeared to lessen in 2023 compared to 2022.
