Why are solar & energy storage costs rising in Q4 2025?

Equipment procurement costs for solar and energy storage will jump around 9% starting in Q4 2025, marking the end of the bargain pricing developers have enjoyed for the last 18 months. That’s because China is changing the rules. Wood Mackenzie points to three major drivers behind the coming spike: Polysilicon consolidation.

Are solar and energy storage prices about to rise?

Solar and storage prices are about to rise after a year and a half of record lows, according to new data from Wood Mackenzie. Equipment procurement costs for solar and energy storage will jump around 9% starting in Q4 2025, marking the end of the bargain pricing developers have enjoyed for the last 18 months.

How much does a battery storage system cost?

Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices had fallen 40% from 2023 numbers to US$165/kWh in 2024.

Will a 60% tariff increase energy storage costs?

“What we found is that with the 60% tariff, the cost [of a turnkey energy storage system] increases by 60% compared to 2025, so this is quite a big cost jump if the US actually decided to do so,” Kikuma says.
