Japan Solar Energy Industry Trends and Drivers:

Strong support from the government for renewable energy, along with stringent policy mandates for the reduction of carbon emissions and the need to become energy self-sufficient, are driving the Japan solar energy market. After the Fukushima nuclear disaster, Japan has recently renewed its commitment to diversify its energy supply away from nuclear power and fossil fuel imports. Favorable policies, such as feed-in-tariff schemes, renewable energy subsidies and tax rebates, have the potential to drive the acceptance of solar energy in the residential, commercial and utility sectors. Declining solar photovoltaic technology costs, coupled with improvements in solar panel efficiency and energy storage technologies are driving the economic feasibility of solar energy for both investors and consumers.

In addition, increasing concerns on climate changes and environmental sustainability are motivating both individual homes and companies to adopt solar energy systems as part of their corporate social responsibility (CSR) and sustainability agendas. Due to Japan's scarcity of land it has also led to developments in deploying solar through rooftop, floating solar and BIPV (building integrated photovoltaics). The growing use of energy management systems and smart grid technologies is providing greater opportunities for solar to tie into the energy infrastructure. The growth of residential solar installations is being facilitated by financing options, leased systems and community solar programs that allow for a less constrained pool of adopters. And Japan’s high levels of technology innovation and manufacturing scale in solar technology enable it to be the highest tier producer of high efficiency solar panels and related equipment. Corporate commitments to net-zero emissions and a growing number of large corporations procuring renewable energy are also driving further market growth. Ongoing support from the government policies and increasing investments of private sector in large scale solar projects bode well for the Japanese solar energy market.
