The Japanese photovoltaic (PV) market is set to grow by 120 percent in 2013 and install more than 5 gigawatts (GW) of new capacity, according to a new report, "The PV Market in Japan," from IMS Research, now part of IHS. Benefiting from the world's most attractive PV incentive policy, Japan's solar market is currently booming, with installations expected to exceed 1 GW in the first quarter alone, causing it to become the second largest market in 2013.

Overly Generous Incentives Spurs a Booming Market
Japan's PV market currently benefits from a feed-in tariff (FIT) paying up to YEN 42 per kilowatt hour, even though this is likely to be reduced by approximately 10 percent beginning April 1.

"At YEN 42 Japan's FIT is by far the most attractive globally-overly generous perhaps, which could lead to overheating of the market," explained Ash Sharma, senior director of solar research at IHS.

"And while a 10 percent reduction in tariffs is widely expected by industry players, this will have little effect on both internal rates of return and market demand. Furthermore, many systems that have already applied for the higher FIT are able to benefit from this rate of YEN 42 even if they are installed after April 1,"

The report reveals that installations are estimated at over 1 GW in the first quarter of 2013-the final quarter of Japan's fiscal year-and forecast to exceed 5 GW for the whole of 2013. This would see Japan leapfrog ahead of Germany, Italy, and the U.S. to become the world's second largest PV market.

A Lifeline for Japanese Manufacturers
IHS research found that domestic PV installations are proving to be a lifeline for struggling Japanese companies that are able to sell both modules and inverters at high margins, despite their competitiveness at an international level falling behind their overseas peers. Providers of residential 'system kits,' EPCs and project developers are also seemingly enjoying the high margins that come with a generous FIT and its resulting high system prices.

"Residential system prices in Japan are roughly double than those installed in Germany. The ability to sell modules and inverters at significant premium compared to the rest of the world, coupled with high demand and growth, provides a much-needed profit stream for Japanese suppliers," commented Frank Xie, report co-author and IHS senior analyst for PV and solar research.

Although Japan has been reportedly attempting to attract foreign PV companies to its shores in order to help accelerate supply-and hence, installations-the report found that it remains a tough market for non-Japanese companies in which to compete.

"While many Chinese and even U.S. module suppliers are now serving the Japanese market, they remain the minority and have largely needed to resort to OEM agreements and partnerships with Japanese manufacturers, despite being highly regarded brands in the rest of the world. Simply put, Japanese customers want to buy Japanese modules.

"Non-Japanese inverter companies have found it even harder to serve this market as tough regulations from the certification board-JET-and even more stringent requirements from utilities have meant that substantial product redesigns are required before they are able to target this market effectively. As a result, the market is currently suffering from a bottleneck in inverter supply," observed Sharma.

Mega Demand for 'Mega Solar' - But for How Long?
Projects more than 2 megawatts in size-or 'mega solar'-in Japan are a major driving force behind the country's triple-digit growth rate, but this is expected to be short-lived, according to the report, and the projects will face a decline after 2013.

"These so-called 'mega-solar' projects are being deployed at a rapid rate, and we expect they will account for approximately 25 percent of total demand in 2013," Xie noted.

"Government policy is in clear support of these projects while the country grapples with severe energy shortages following its shunning of nuclear power. However, this is likely to be short-lived and decline after 2014 once the current pipeline of approved projects is completed, largely because of a shortage of land in the country."

Sharma concluded: "Another segment of the market that gets fewer Japan to Install More than 5 Gigawatts of PV Systems in 2013s, but should not be neglected, is commercial rooftops. Systems in the range of 10-50 kilowatts are in very high demand in Japan due to high incentives, high electricity prices, power shortages for commercial properties and relatively simple regulations for installations of this size."
