Coupled solar and energy storage market to grow to $2.8 billion in 2018

Dominated by grid installations, the coupled solar and energy storage segment will prove a boon to energy storage producers but have only a modest impact on the solar market, according to a new report by Lux Research.

Developers are eager to package solar and storage systems.

Companies eager to combine solar and energy storage technology to differentiate products and defend margins could yield lucrative results. Lux Research predicts this symbiotic match could result in a $2.8 billion market over the next five years.

Grid-tied solar installations will comprise 675 MW, or nearly 95% of the combined 711 MW market, while off-grid applications, including telecom power, will claim the remaining 5%, Lux finds. While the off-grid market enjoys higher profit margins, the much larger addressable market for grid-tied systems means they dominate the solar and energy storage market.

''Developers are pushing packaged solar and storage systems in order to stand out as value-adding leaders, but not all benefit equally,'' said Steven Minnihan, Lux Research senior analyst and a co-author of the report titled ''Batteries Included: Gauging Near-Term Prospect for Solar/Energy Storage Systems.''

He added that ''residential energy storage will see a boost adoption due to solar, but the addition of storage will barely move the needle for solar players, driving a paltry 1% increase in global PV sales.''

Assessing the emerging market for combined solar and energy storage, Lux Research analysts found that:

  • Residential applications will dominate through 2018. As lithium-ion (Li-ion) batteries and overall storage arrays fall in price, residential systems will gain the most, growing to 382 MW in 2018. The light commercial segment will increase to 220 MW while heavy commercial/industrial systems will lag, growing only to 73.3 MW.
  • Japan will remain the worldwide leader. Hit by high electricity prices and seeking alternative energy after the nuclear woes, Japan will install 381 MW of solar coupled with storage by 2018, leading all other markets by a wide margin. Germany will come in second at 94 MW, while the U.S. will be third at 75 MW.
  • Newfound storage policies may dramatically increase the market. This year, Germany set aside $67 million to subsidize solar-tied energy storage and the U.S. Senate introduced a program that could fund $7.5 billion worth of new storage projects, or about 7.5 GWh of capacity.
