An independent power producerthat develops, invests in and operatessolar power plants
Since its founding in 2014, SIE CO.,LTD. has developed solar power plants, invested in and held them, and run them in-house as an independent power producer. As we shift from FIT to non-FIT corporate PPAs, we are actively seeking land and development projects for solar power.

Our Business
Develop, invest, operate: solar power end to end
SIE CO.,LTD. is a solar developer and also an independent power producer that invests in and holds power plants. We handle everything from securing land and applying for grid connection to commissioning construction from partner contractors, then hold and operate the finished plants. If you need modules, mounting structures or other equipment, we can import and supply them too — a full-service partner for solar.

Plant development
We secure land and apply for grid connection in-house, and commission construction from partner contractors. Since 2014 we have developed around 20MW of solar capacity a year in Japan, assessing every site carefully with the expertise of our Taiwan headquarters.

Investment and ownership (non-FIT / PPA)
We invest in the plants we develop and hold them for the long term. Rather than relying on FIT, we develop plants that supply power directly to companies under PPAs; with the offtaker in place first, a project moves forward smoothly once land is secured. Our Taiwan headquarters’ long-term PPAs with major semiconductor makers inform how we structure projects in Japan.

In-house O&M
We run operation and maintenance ourselves. Our in-house remote monitoring system, S.I.E.侍, watches every plant around the clock, shows generation and revenue at any time, and pinpoints faults so only the affected part is fixed, keeping lost sales to a minimum.

Equipment & Systems
Import and sale of solar equipment
Plant equipment is part of what we do. We import solar modules, mounting structures and other equipment to suit each project’s specifications and supply them to you, drawing on what we have learned running power plants to help with equipment selection. Enquiries about equipment reuse are welcome too.
Solar modules
Modules imported and supplied to match your project’s size and specifications.
Mounting structures
Racking sourced to suit the terrain and installation conditions.
Balance-of-system parts
Cables, junction boxes and other components a plant needs.
Quantities, specifications and lead times are quoted per project.
Ask about equipmentDeveloped in-houseRemote monitoring system “S.I.E.侍”
S.I.E.侍 is a remote monitoring system for solar power plants: log in and everything is clear at a glance. See how each plant is running on one screen, with daily and monthly reports as easy to work with as a spreadsheet, so the condition of every plant can be checked in a short time. The system watches over all your solar power plants 24 hours a day, 365 days a year. No specialist knowledge is needed: follow revenue and faults in real time and keep lost electricity sales to a minimum.
Fix only what is faultyThe system pinpoints where a fault lies, so only that part is dealt with, with no need to shut down the whole plant to search for it.
Real-time revenue dataGeneration and sales revenue are uploaded as they happen, so you can check actual output at any time without waiting for the month-end.
Simple, clear operationA clear, intuitive interface anyone can use without specialist knowledge, with reports you can browse as freely as a spreadsheet.
