Judging from the rankings of and the positions taken up by module, inverter, downstream EPC contractors and bank and life insurance companies in 2018, EnergyTrend analyst Sharon Chen points out that though the market scale for PV systems aren't as large as that of wind power, the PV market has already undergone a long formation process. Consider further the fact that PV charging stations have a relatively steady and high return on investment, and it's not hard to see why even banks and life insurance firms are scrambling to claim a portion of this market.

The module market of 2018 differed from 2017's, which saw Neo Solar Power (NSP) and AU Optronics (AUO) as the leading double eagle. URE benefited greatly from its three-in-one strategy, with NSP as the surviving company combining both Gintech and Solartech to become the top contender by module shipments in Taiwan, 2018: It reached 500MW in total shipments, with market shares leaping from 30% in 2017 to 48% in 2018.

In comparison to URE, AUO maintained a global, overseas strategy, ensuring a consistent number of yearly shipments. This put its 2018 shipments on a par with those in 2017, fully demonstrating its global strategy as the most stable among Taiwan module manufacturers.

The annual number of new installations of PV systems in Taiwan reached 1GW for the first time in 2018, nearly a one-fold increase from 2017 (520MW). Thus shipments for all vendors doubled in the inverter market. But competitors are rushing in as the market expands, splitting the market shares of pre-existent products. Apart from SMA, whose market share in the Taiwan region remained sure and steady, inverter manufacturers at home and abroad all experienced a decline in market shares in 2018, including Delta.

Delta still holds first place in inverter shipments for 2018. Although its market shares dropped by 10% compared to 2017, it nevertheless boasted double the shipments of second-place company, Satcon, which has Skwentex acting as sales representative in Taiwan, and reached this position in shipments thanks to the 100MW demonstration program carried out by the Renewable Energy Department under Taiwan Power Co.
