Technical FAQs 4

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.

What are energy storage technologies?

Energy storage technologies, store energy either as electricity or heat/cold, so it can be used at a later time. With the growth in electric vehicle sales, battery storage costs have fallen rapidly due to economies of scale and technology improvements.

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.

What is NREL's solar-plus-storage cost benchmarking work?
