Prices have begun to fall after a brief stabilization phase – declining by around 5% to 8% across all technology classes in recent weeks. This drop returns prices to levels seen at the beginning of the year, a range that remains unprofitable for most module producers. . The analysis and cost model results in this presentation (“Data”) are provided by the National Renewable Energy Laboratory (“NREL”), which is operated by the Alliance for Sustainable Energy LLC (“Alliance”) for the U. Department of Energy (the “DOE”). 8 gigawatts direct current (GWdc) of capacity in Q1 2025, a 7% decline from Q1 2024 and a 43% decrease compared with Q4 2024 but still the fourth largest quarter on record. Solar accounted for 69% of all new electricity-generating capacity added to the US grid in. . After holding steady for much of Q1, distributed generation (DG) solar module prices spiked mid-Q2 — only to partially settle by the end of June, according to Anza's latest pricing insights report. 28/W, ending years of dramatic fluctuations as supply-demand dynamics rebalance and weak suppliers exit the market. TOPCon Technology Dominance: TOPCon modules have. . In early April 2025, the United States enacted sweeping “reciprocal tariffs” on imports, aiming to mirror (at a discounted rate) the trade barriers faced by U.

Accordingly, GSTAR's latest price lists show significantly higher numbers (on the order of $0.18–$0.20+ per watt in bulk) to account for the 36% tariff on Thai-made modules or 48% on Laos-made components. Even with these increases, GSTAR modules remain competitively priced; but the gap to U.S. or non-tariffed panels has narrowed.
In summary, as of April 2025 we see solar panel prices up by 20–40% (depending on origin), inverters up ~10–30%, and battery costs up significantly (~30% or more) compared to pre-tariff levels. These increases correlate directly with the reciprocal tariff rates imposed (34% on China, 36–49% on SE Asia, etc.), underlining the tariffs' impact.
SolarSpace – a Chinese-based module supplier – raised its U.S. wholesale price from roughly $0.22 per watt to about $0.297 per watt in April, an increase of ~35%. This jump closely matches the new 34% tariff on Chinese goods, indicating the cost is being passed through to buyers.
Commercial PV system prices fell 2% annually to $1.47/Wdc, while utility-scale fixed-tilt system prices dropped 1% to $1.18/Wdc. Single-axis tracking system prices remained stable at $1.23/Wdc. This counterintuitive trend in the commercial and utility-scale segments stems from technological advancements and cost-saving measures.
