Market Overview

The Japanese market for encapsulation materials for Solar Energy is comprised of transparent polymers and adhesives such as EVA, PVB, and TPU, among others. These capsule materials surround PV cells within a Solar cell module and provide long-term performance and protection for Solar PV cells in a variety of climate conditions. In addition to enhancing durability, insulation, and light transmittance within Solar modules, encapsulants also offer greater reliability. With Japan's introduction of regulations to promote the development and increased use of renewable energy and to increase security of domestic energy supplies, the solar encapsulation market has a significant opportunity for growth. Encapsulation products are being applied to more and more residential and commercial rooftop installations, thereby creating demand for highly efficient encapsulation products. The accelerated growth in commercial use of innovative Solar technologies, including bifacial modules and higher efficiency Monocrystalline cells, is also driving the need for more advanced encapsulation materials. Companies producing these advanced encapsulating materials are, in turn, required to produce them to offer superior UV resistance, minimal degradation rates, and improved adhesive characteristics. To promote renewable energy and long-term decarbonization, the government of Japan supports the growth of solar energy with a combination of policies and funding. The programs developed by the government are consistent with Japan's goal to achieve carbon neutrality by 2050, and have enabled an increase in the usage of large-scale solar systems, along with further development of solar technology in Japan.
