0-zero.jp is the official website of Kabushiki Kaisha ZERO, a local engineering company based in Fukuoka Prefecture, Japan. Founded in 1993, the company originally focused on waterproofing renovation, civil engineering, and other public and private construction projects. In recent years, it has expanded into the sales and installation of residential solar photovoltaic (PV) systems and home energy storage systems. Its current service coverage spans the entire Kyushu region of Japan and parts of the Chugoku region (areas around Yamaguchi Prefecture).
The company's core business is divided into two main areas: traditional engineering services such as building renovation, waterproofing, and seismic reinforcement; and the sales and installation of solar PV modules and home energy storage systems. For its new energy products, the official website publishes the manufacturer's suggested retail prices of key hardware components. PV inverters range from ¥235,000 to ¥445,000 (excluding tax), while a single 315W solar module is priced at approximately ¥185,900 (excluding tax). Full-project pricing, however, requires a custom quote based on the specific property, and users can call to request a proposal. Two energy storage options are available: the compact all-in-one SmartPV, and the large-capacity Smart Star L equipped with AI-based optimization—catering to the electricity needs of different household types.
The website has a clear information architecture, with transparent disclosure of product specifications, service workflows, and company credentials, allowing users to quickly understand its offerings. However, the site is available only in Japanese, with no Chinese or English interface, which is unfriendly to non-Japanese-speaking users. The website is directly accessible from within China, but since its services are aimed exclusively at local users in Japan, users based in China cannot actually make use of them.
This website primarily serves local residents in Kyushu and surrounding regions of Japan who need residential solar-plus-storage installation or building renovation services.
