"The module-level power electronics sector has grown from a niche market to mainstream, especially in the United States, where there is fierce competition in major solar PV markets like California," says Dexter Gauntlett, senior research analyst with Navigant Research. "What's more, a growing number of solar PV module manufacturers are now integrating microinverters and DC optimizers at their own production plants. At the same time, large power electronics companies and incumbent manufacturers are making strategic partnerships and acquisitions to take advantage of rapid growth in this market segment."
