The US market for solar-plus-storage is predicted to grow more than twentyfold in the next three years, rapidly expanding from US$42 million in value this year to US$1 billion by 2018, according to GTM Research.

The US-based solar division of Japan’s Kyocera and energy service start-up STEM have become the latest partnership to offer integrated solar-plus-storage to commercial customers in the US, beginning with sales in three states including California.

Neither commercial-scale nor energy storage have yet take off in the US. But as Felicity Carus reports, this could be about change as companies eye opportunities in both segments.
