2013 PV Inverter Supplier Rankings: Asian Suppliers Tighten Grip as European Leadership Weakens

The number of Asian companies appearing among the world's 10 largest photovoltaic (PV) inverter suppliers doubled in 2013, with four from China and Japan appearing within the charmed circle, compared to just two in 2012 and none in 2011, according to new analysis from IHS Technology.

Rising demand for PV inverters from Asian markets has resulted in domestic suppliers accounting for a growing share of the global market. China and Japan together represented 35 percent of global PV inverter revenue in 2013, unlike just 12 percent in 2011. Capitalizing on the high-entry barriers to international suppliers in these booming regions, Asian suppliers have succeeded in dominating their domestic markets and have now been catapulted into the global top 10, as shown in the attached table.

These findings can be found in the report, "PV Inverter World Market Report - 2014," from the Power & Energy service of IHS.

Inverters play an essential role in PV installations, converting the direct current (DC) electricity produced by solar panels into alternating current (AC).

Chinese-based inverter manufacturer Sungrow continued to command a leading position in the fast-growing Chinese market. In last year's final quarter alone, the company shipped over 2 gigawatts (GW) of inverters, the majority to its domestic market. China underwent an intense rush to complete photovoltaic systems before the end of 2013 in order to beat a scheduled decrease in the feed-in tariff rate.

Sungrow's shipments nearly equaled a record held by Germany's SMA Solar Technology, which achieved almost 2.4 GW of global shipments during a single quarter in 2010. But even though Sungrow shipped more inverters in megawatt terms in the final quarter of 2013 than any other supplier, extremely low average prices for central inverters in China meant that it was only the second largest supplier in revenue. Even so, this marked a notable increase considering that Sungrow had not appeared in the top 10 during any other single quarter in 2013.

Japanese suppliers Omron, TMEIC and Tabuchi also appeared in the top10 for 2013. PV installations in Japan last year are estimated to have grown nearly threefold, making up 17 percent of global demand. As the three largest PV inverter suppliers in Japan, Omron, TMEIC and Tabuchi are also the third, fourth and seventh largest suppliers in the world, respectively.

"The rate at which the solar landscape has transformed has been incredible, and it has initiated a major shift in the competitive environment for PV inverter suppliers," said Sam Wilkinson, solar research manager at IHS. "As growth from China and Japan continues to outpace the global market in 2014, both Chinese and Japanese suppliers are likely to further improve their positions in 2014."

While the domestic business of these four Asian suppliers has enabled them to achieve significant share in global market revenues, all have minimal sales outside of their home markets.

"Although Asian suppliers have had a huge impact on the global rankings due to their success in local markets, their bearing on international markets outside of China and Japan has currently been quite limited," noted Wilkinson. "Just the same, the economies of scale, expertise and brand strength that they have now been able to achieve makes them well placed for international expansion, and the world is likely to see many of these suppliers play a greater role in markets outside Asia over the next two to three years."
