Japan Solar Energy Industry Trends and Drivers:

The Japan solar power market is being poised for strong growth, supported by ambitious renewable energy targets subsequent to the post-Fukushima energy policy revision and realizing cost reduction of solar technologies and government measures promoting solar power utilisation for residential, commercial, and utility-scale. With Japan's goal of achieving carbon neutrality by 2050 and large-scale renewable energy capacity targets, solar power remains a pillar of Japan's energy transition strategy, and ambitious installation targets mean solar capacity needs to be ramped up at a dramatic rate. Although the feed-in tariff scheme has been reduced from levels in previous years, it still supports returns on solar investment, and emerging policy mechanisms such as auctions and renewable portfolio standards are leading to the development of utility-scale projects. Corporate renewable energy commitments and the RE100 initiative require major Japanese companies to source solar power via PPAs and through on-site developments, and that drives ongoing demand in commercial & industrial solar.

The market is driven by ongoing technological development in solar panel efficiency and cost, and the adaptation for use in space-limited areas prevailing in the concentrated urban areas of Japan. The use of high efficiency bifacial panels, building integrated photovoltaics and floating solar solutions, allows the generation in limited space, working around Japan's land shortage problem. And rooftop solar is taking off for household users as installation procedures become simpler, financing schemes such as solar leasing and power purchase agreements are converted needs uptick & awareness of the benefit of electricity cost reductions and energy independence is expanding. In addition, battery storage integration with solar systems mitigates intermittency issues, while also serving as a backup power source during natural disasters and grid outages, which boosts the value proposition for solar, especially in regions vulnerable to natural disasters. The rise of virtual power plants aggregating distributed solar resources and continued grid modernization—allowing for greater renewable penetration—are aligning to support ongoing solar growth. On-site corporate solar adoption, however – out in the commercial and industrial sector – further proves solar’s financial practicality, in addition to the purely environmental reasons, across the Japan solar energy market.
