Kyocera Corporation has announced its first commercialized monocrystalline silicon solar modules, which it will begin fully supplying for the Japanese residential market in April.

In the Japanese residential market, there is strong demand for high-output solar modules in order to generate electricity efficiently on limited rooftop spaces

In an effort to respond to these needs, Kyocera has been conducting R&D in monocrystalline solar modules, which feature higher power generation efficiency compared with polycrystalline modules, and plans to raise the conversion efficiency of its monocrystalline cells from 19% to more than 22% within the next few years.

Having established the technology to ensure high quality and long-term reliability, the company will begin fully supplying monocrystalline modules in addition to its current polycrystalline modules.

In addition, Kyocera has succeeded in developing polycrystalline silicon solar cells with a conversion efficiency of 18.6%*1, exceeding the company’s record (17.8%) by 0.8%.

The new conversion efficiency of 18.6% was achieved through the enhancement of crystal quality, improvement in the electrode process and reduction of carrier recombination. Sales of the further enhanced polycrystalline silicon solar cells will commence this summer in Japan.
