Solar-Plus-Storage Still Has Barriers

The anticipation is from the potential for the first wave of growth in markets such as California and Hawaii.

The combination of solar photovoltaics with energy storage for electricity customers has been receiving "tremendous" attention in the last few months. According to a report from GTM Research, the anticipation is from the potential for the first wave of growth in markets such as California and Hawaii.

The annual market for solar-plus-storage is expected to grow from $42 million in 2014 to more than $1 billion by 2018, according to the report. Barriers remain for solar plus storage to be a viable option, including cost reductions being in the early stages and business models that need "continued refinement."

California, New Jersey and New York do have upfront incentive programs for behind-the-meter solar and storage: "California’s Small Generation Incentive Program, in particular, has facilitated the deployment of several megawatts’ worth of solar-plus-storage to date. For a typical commercial end customer, solar-plus-storage systems can provide electricity bill savings of 20% to 30%, depending on system size. More than half of those savings typically stem from demand-charge reductions," the GTM Research report said.

GTM's report focuses on behind-the-meter segments of residential and non-residential, providing a comprehensive analysis of the nascent but accelerating solar-plus-storage market, including market drivers and barriers, end-customer economics, the evolving vendor ecosystem, and a market outlook.
