Japan Solar Panel Industry Trends and Drivers:

The Japan solar panel market is anticipated to grow at a significant pace owing to the country s declaration of becoming carbon neutral by 2050 and its move towards the use of more renewable energy. After Japan s Fukushima nuclear tragedy, the country rapidly distanced itself from nuclear power, providing huge prospects for solar penetration. Government policies such as favorable feed-in tariff schemes, subsidies for household solar systems, and regulations that facilitate the integration of renewable energy sources have largely contributed to the expansion of the market. Decreasing costs of solar panel hardware and increasing efficiency and rates of energy conversion have made solar power very cost competitive with traditional energy resources. Corporate sustainability objectives, along with the continued growth in business renewable energy adoption, are also spurring installations of large-scale commercial and industrial solar across the nation.

The market is also driven by advances in solar panel designs, such as monocrystalline and thin-film high-efficiency technologies that allow to produce more energy in less space. Japan’s space limitations have inspired solutions such as rooftop-mounted arrays, floating solar arrays on lakes, and solar panels integrated into building materials. Rising energy prices and energy security considerations have also prompted consumers and businesses to purchase solar power systems to lessen reliance on energy imports. The development of energy storage and smart grid power generation technologies has made solar energy more viable by mitigating the problem of discontinuity. In addition, growing environmental consciousness among Japanese consumers and the natural disaster preparedness viewpoint has raised the value of distributed solar power generation as a dependable and sustainable energy option for both residential and commercial fields.
