Solar Light Harvesting System 'Himawari' for Medium and Large Facilities
XD-100S/36ASN
Contributing to the realization of a decarbonized society and the promotion of SDGs! A solar light collection system for medium to large facilities, 'Sunflower', that collects sunlight and transports it freely.
The "Sunlight Collection System Himawari," which collects sunlight and transports it via fiber optic cables, has been significantly renewed for medium to large-scale facilities, with orders starting in March 2026. With approximately 40% weight reduction and improved weather resistance of the equipment, long-term use becomes possible. "Himawari" will contribute to various locations and purposes, targeting public facilities, office buildings, commercial facilities, medical facilities, and educational and research institutions both domestically and internationally, promoting SDGs, reducing CO2 emissions through lighting use, and enhancing well-being through natural light collection. 【Contribution to SDGs】 ○ Goal 7: "Affordable and Clean Energy for All" By directly utilizing renewable energy (solar power), it reduces electricity consumption for daytime lighting and promotes the use of clean energy. ○ Goal 11: "Sustainable Cities and Communities" It brings natural light into windowless rooms and basements in offices, schools, hospitals, and factories, providing a healthy and comfortable spatial environment. ○ Goal 13: "Climate Action" By reducing energy consumption used for lighting, it contributes to CO2 emission reduction and supports the realization of a decarbonized society.

Applications/Examples of results
There is a wide range of implementation results from public facilities, commercial facilities, educational institutions, hospitals and welfare facilities to general housing and collective housing. **Benefits of Introducing Himawari** (1) Energy-saving and power-saving effects The power consumption is a maximum of 5W for the 100V drive type. This can significantly reduce the power used for daytime lighting. The solar-powered model has zero power consumption, allowing for even greater energy-saving effects. (2) Positive impact on health The visual comfort from natural light improves, which can help alleviate feelings of confinement indoors and is expected to regulate the circadian rhythm (body clock). (3) Disaster prevention and safety measures: Even during sudden power outages due to disasters, using the solar-powered model can ensure the necessary illumination during the day, enabling business continuity and being effective for BCP (Business Continuity Planning) measures.
Detailed information
-
- The main concentrator should be installed in a location where direct sunlight can reach stably during the day. - The fiber optic cable should be laid out through the shortest possible route using interior and exterior wall piping. - The irradiation equipment is determined based on the irradiation area and the effective dimensions within the ceiling.
