For new renewable energy business, advanced countries, public companies of such countries and global companies continue to develop technology for the smart grid market and significant level of technology has been already commercialized in advanced countries. On the other hand, research and development and commercialization of appropriate sustainable technology for low income earners in developing countries are still in a low level. Under this circumstance, we have developed solar lanterns, portable solar generators and off-grid solar homes, aiming to achieve commercialization of appropriate technology for people whose income is lower than USD 2,500 to enjoy the minimum cultural life. Since the establishment on November 1, 2016, we are growing with continual increase of exportation by expanding our production lines and development and joint marketing of portable solar generators (e.g. SG-24 and K-4 AIO-10) as a company specialized in off-grid (e.g. SH-1000 and SH-2000). Recently, we indirectly exported USD 10 million of home solar generator model SH-500, which has been developed by off-grid solar home system technology, to Honduras, South America.
