Notus Solar Japan

What Notus Solar Japan does

Notus Solar Japan Co., Ltd. (ノータスソーラージャパン株式会社) is a privately held Osaka-based company, founded on April 15, 2022, that develops, operates, and supplies agrivoltaic solar power generation systems in Japan. Its core product, the Notus Solar System, is a 3D-tracking photovoltaic system adapted from REMTEC's internationally patented 'Agrovoltaico' technology under an exclusive domestic license, featuring movable panels with adjustable shading, wide farming space, and automatic horizontal-mode repositioning during typhoons and snowfall. The company targets RE100-committed listed corporations via PPA models (on-site, off-site, self-generation self-consignment), local governments pursuing zero-carbon goals, agricultural cooperatives, EPC/construction firms, and individual farmers seeking supplementary income.

The business model combines electricity sales from owned-and-operated agrivoltaic plants (FIT and PPA schemes) with one-time system design and manufacturing revenue, project development consulting, agrifarming consulting, and ongoing O&M. Go-to-market is enterprise field sales augmented by three large strategic partners — Toda Corporation (construction), Sunfrontier Real Estate (real estate), and Sinanen Holdings and its EPC/O&M subsidiary Sinanen Facility (PPA distribution and operations) — enabling nationwide deployment rather than reliance on a small internal team (1-10 employees). Currently operating assets are two small Ibaraki sites (each 85.76 kW DC, connected 2020 and 2021) with sweet potato cultivation; the Iga test plant in Mie Prefecture (54.24 kW, connected 2021) was destroyed by Typhoon No. 7 in August 2023, and a much larger 3,531 kW / 64,660 m² Iga development is in planning, targeting RE100 corporations. Cumulative capital raised reached ¥110.01 million as of March 31, 2025, across four capital increases, with listed strategic shareholders including Toda, Sunfrontier, and Sinanen alongside the founder-CEO Ryuzo Takahashi and several agricultural and transport entities.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Renova, Inc. Japanese renewable energy independent power producer developing utility-scale solar, biomass, and wind projects. Comparable as a domestic renewable IPP scaling toward similar enterprise off-takers, though not agrivoltaic-focused.
• Trinasolar: Global solar module manufacturer and project developer with agrivoltaic initiatives. Comparable as a vertically-integrated solar participant, though primarily a hardware manufacturer rather than a pure project developer/IPP.
• BayWa r.e. AG: Global renewable energy developer with active agrivoltaic project portfolio in Europe. Comparable as a large-scale agrivoltaic and solar project developer pursuing similar dual-land-use business models internationally.
• West Holdings Corporation: Major Japanese solar project developer and IPP with a large domestic portfolio. Comparable as a scaled Japanese solar project developer pursuing power sales and PPA structures, though focused on conventional ground-mount solar.
• Lightsource bp: Global utility-scale solar project developer and IPP pursuing PPA structures with enterprise customers. Comparable as a scaled solar developer/IPP using PPA models—though not agrivoltaic-focused.

Regional players

• Next Energy & Resources Co., Ltd. Japanese solar module distributor and project developer with domestic EPC and O&M capabilities. Comparable as a domestic Japanese solar value-chain participant serving similar enterprise/government customers, though not specialized in agrivoltaics.

Others

• REMTEC: Italian technology owner of the Agrovoltaico 3D tracking PV technology licensed to Notus Solar Japan. Not a direct Japanese competitor (Notus holds the exclusive Japan license), but a comparable agrivoltaic technology developer and ecosystem partner in other geographies.

Direct peers

• Sun'Agri: French agrivoltaic specialist developing dynamic solar systems that coexist with crop cultivation—directly comparable agrivoltaic project development and technology model in a European market.
