Also, there have been low-cost alternative products. The string inverters coupled with power optimizers for improving output powers will further enable high performance. In addition to this, on the islands, energy storage systems are integrated within String Inverters. Thus, with the high penetration of renewable sources of energy, string inverter market growth will be on the rise.


Segment Overview- The market segments for string inverters includes system type, phase, end-users, and power rating.


By System Type- It includes on and off grids. In the year 2015, the on-grid segment witnessed the highest market growth in the string inverter market. As the usage of On-grid systems is majorly in small and medium solar panels used in commercial and industrial sectors.  In the utility sector, large solar panels are generally used. However, its scope in utility is lower than compared to industrial and commercial sectors.


By Phase- The market for string inverters is further categorized into Single- Phase and Three- Phase.


By End- Users- It is divided into commercial, utility, and industrial.  During the forecast period, the growth rate in the utility sector will be highest. Also, due to improvements in renewable integration regulations has will accelerate string inverter market growth. Also, string promotions from manufacturers are witnessed on the installation of three-phase string inverters. This will further boost shipments for large-scale power units in the upcoming four years.


By Power Rating- It includes power ratings up to 10KW, 11KW- 40 KW, 41KW – 80KW, and more than 80 KW. In this view, the 41 KW to 80KW segments has the highest market owing to their size, lightweight. Also, the inverters in this power range offer higher flexibility thus catering to the demands of all power plants sizes. It also enhances protection and durability within a harsh outdoor environment.
