A new survey conducted by IMS Research (now part of IHS Inc.) of more than 400 global photovoltaic (PV) inverter customers has revealed a rapidly growing need for energy storage in PV systems. Despite the infancy of the energy storage market, nearly one-third of respondents indicated that they expect to be using energy storage in over 40% of the PV systems they install by 2015.
The survey, which involved global installers, system integrators and wholesalers, also revealed that Chinese PV inverters are continuing to gain acceptance and the high price of micro-inverters is the main barrier to their gaining market share.
When asked which requirement they saw becoming most important over the next two years, respondents from Germany, Italy and the U.K. selected energy storage as more critical than any other requirement for future PV inverters.
When asked what the main driver for the adoption of energy storage would be, the most common response from customers was a reduction in battery prices helping to drive lower system prices and make storage financially viable.
The survey found that over 60% of respondents believed that an acceptable increase in system price for the inclusion of energy storage would be between 10% and 29%. However, almost 30% of respondents indicated that they would be willing to pay an even higher premium.
"Energy storage is becoming an increasingly important feature for PV systems, and if suppliers are able to deliver products in line with the industry's expectations, the market for energy storage in PV could increase significantly over the next two years," explains Sam Wilkinson, manager of power and energy research at IHS.
