Japan Solar Energy Industry Trends and Drivers:
The Japan solar energy market is predicted to witness significant growth due to strong promotion of renewable energy by the country and nuclear and fossil fuel dependence reduction after the Fukushima disaster. Japan's aggressive renewable energy goals to dramatically increase the percentage of renewables in its national energy mix have made solar power a mainstay in the country's energy portfolio. The feed-in tariff scheme of the government though being slowly phased out, put the solar industry on a firm footing, which the industry can further develop by depending on other support measures such as the feed-in premiums and the renewable energy auctions. Falling costs for solar photovoltaic (PV) technology, increases in panel efficiency, and advancement in energy storage solutions have allowed solar energy to be cost-competitive and financially sustainable for a range of applications including residential rooftops to utility-scale solar projects.
The market is also advantaged by corporate sustainability pledges and an increasing penetration of the commercial and industrial segment, wherein enterprises are adopting clean energy sources to reduce their carbon footprint and fulfill their environmental, social and governance compliance. Owing to scarce land, Japan is leading in innovations in solar deployment such as floating solar on reservoirs and other water bodies, agrivoltaics, higher and closer spacing for panel installation on farmlands, flat rooftops turned into farms, and more efficient use of rooftops through installation on walls and ceilings of carports, among others. The strong residential market is expected to remain a growth engine as more and more homeowners are realizing the long term financial benefits of going solar, especially now that solar systems are increasingly being paired with battery storage solutions for greater energy independence and protection from power outages. Developments and improvements in bifacial panels, tracking systems, and power electronics allow more energy generation and better system performance. Furthermore, the increasing electrification of transport and the potential for vehicles to provide grid services are creating new synergies between solar energy and electric vehicle adoption. Government’s renewable energy policies, community-based solar projects, and also virtual power plant models are opening up access to solar energy for individuals and industries, and hold the promise of new business models thereby accounting for the prevailing growth in the japan solar energy market.
