PV Expo Tokyo 2024, Japan’s most important photo voltaic trade occasion, has concluded with report numbers, progressive merchandise, and new developments. Storage auctions and new guidelines for energy buy agreements (PPAs) are driving the market to new areas, as undertaking builders scramble for land to construct on, whereas light-weight plastic modules proceed to achieve prominence.
Making the most effective of restricted areas was the overarching theme at this 12 months’s Sensible Power Week, held this week at Tokyo Huge Sight. The occasion attracted round 70,000 guests and exhibitors throughout six particular person exhibition areas in 5 halls. The organizers seen a 30% enhance in exhibitors over final 12 months’s present.
Nonetheless, the expansion in exhibitors and guests doesn’t replicate the expansion of the market. Japan’s photo voltaic set up figures have stood regular at round 6 GW to 7 GW per 12 months and can stay at that stage in 2024, mentioned Izumi Kaizuka, director and principal analyst at RTS Corp. She believes the soar in exhibitors occurred as a result of module producers are sitting on a stockpile of modules that must be offered. With China’s set up figures projected to take a slight dip in 2024, competitors to promote modules is rising, main producers to promote their merchandise in each market they’ll – and Japan is not any exception.
That mentioned, the Japanese market does have distinctive traits. For instance, an absence of accessible land signifies that the market has historically primarily been pushed by the rooftop sector. Japanese residential rooftops are small and fragmented, that means that smaller modules have to be pieced collectively to make use of accessible area, making them extra fashionable than bigger modules with increased effectivity charges.
Japanese producers comparable to Sharp and Panasonic, in addition to long-established suppliers from abroad, meet this demand with their choices for the nation. Trina Photo voltaic, for instance, presents modules with the precise width for standardized corrugated steel roofs in Japan.
For bigger industrial and industrial (C&I) rooftops, weight performs a vital position. Roofs made out of corrugated steel weren’t designed to bear the burden of PV arrays. Due to this fact, many new module producers getting into the Japanese market this 12 months are providing light-weight plastic modules to beat this problem. They vary in weight from 6 kg to 11 kg for 450 W to 550 W modules, with installers adhering them straight onto steel rooftops. Such panels are uncommon in different components of the world, however on the Tokyo occasion, greater than half of the module producers displayed them at their cubicles.
One other (probably Japan-specific) module development is the shortage of a decrease edge on modules for higher water drainage. Longi, DAH Photo voltaic, and lots of different producers displayed modules sprinkled with water, exhibiting that panels with decrease edges accumulate swimming pools of moisture on the backside. Stopping this helps to attenuate soiling, in response to the producers.
Along with rooftop installations, two different sorts of tasks are presently dominant: agrivoltaics and PV for parking tons. Many mounting construction producers exhibited photo voltaic carports for residential and industrial use. Germany-based S-Rack has arrange a department in Japan to promote these sorts of mounting buildings and has reported an enormous soar in demand for such options. S-Rack’s technical gross sales consultant, Jan Habenicht, mentioned the corporate offered 80 methods in Japan final 12 months, up from simply three in 2022.
New PPA guidelines are additionally driving the Japanese carpark PV market, which is making it comparatively straightforward to spend money on tasks. Habenicht mentioned that banks, buyers, and companies with excessive energy demand are actively looking for inexperienced funding choices, together with company PPAs, alongside authorized parking zone homeowners. Native energy firms are additionally looking for companies with massive parking tons for usable PV area. This market is one thing to look at in Japan.
One other massive matter within the Japanese market is storage. Grid congestion points have slammed the northern and southernmost areas of Hokkaido and Kyushu, with curtailment charges of 30% and better for a lot of undertaking homeowners. There isn’t a compensation for curtailed energy in Japan, inflicting undertaking builders to indicate rising curiosity within the co-location of battery storage and ground-mounted PV.
Kaizuka of RTS Corp. mentioned she expects Japan’s PV market to achieve 15 GW of installations per 12 months in 2030 and about 23 GW in 2035. A mixture of upward revisions of renewable power targets, regulatory reform, decrease part costs, and necessary environmental, social and governance (ESG) investments will proceed to drive the Japanese market. Within the years to come back, Japan might hit 279 GW of cumulative installations – nicely above the 117 GW goal in its newest strategic power plan.
