New Revenue from Roof Leasing Model By simply leasing idle assets (roofs), we can earn rental income of approximately 100 to 200 yen per square meter annually. For example, with an 8,000 square meter roof, this translates to stable annual revenue of about 800,000 to 1.6 million yen. *This may vary depending on regional conditions and contract methods.

―― Is attendance management becoming a "burden" without you realizing it? A seminar to quickly learn about common issues and their solutions ―― We will be holding our attendance management web seminar in October, which takes place several times a year! The content is new, so whether you have participated in our webinars before or not, please feel free to join us. Date and Time: October 15 (Wednesday) 13:00- October 22 (Wednesday) 11:00- *Both days will cover the same content *Please check the link below for registration. In this seminar, we will recreate common situations in the workplace in a short drama format for easy understanding, and introduce specific solutions to each issue. This content is especially recommended for those who think, "I'm not struggling now, but I want to know information for the future." Common workplace "situations" can be a trigger for improvement. We will clearly present the challenges and countermeasures of attendance management. Recommended for: ❏ Those who take a long time to compile monthly attendance ❏ Those who tend to postpone compliance with legal revisions ❏ Those who currently have no major complaints but want to know hints for improvement ❏ Those who want to refer to initiatives and examples from other companies

On Monday, September 22, the Japan Meteorological Agency announced its three-month forecast for October to December. Due to the continued influence of conditions similar to the La Niña phenomenon until around December, the westerly winds are expected to flow more to the north than usual from October to early November, making it likely that warm air will cover the entire country. From late November to December, the westerly winds are expected to meander southward near Japan, and there may be periods when the winter pressure pattern strengthens. In December, the region is likely to be affected by cold air, and temperatures in western and eastern Japan are expected to be around or lower than the average for the season.

~ Are lightweight, flexible solar panels becoming mainstream? ~ Film-type perovskite solar cells, organic thin-film solar cells, and lightweight crystalline silicon solar cells are all lightweight and flexible solar panels that stand apart from the traditional "heavy and rigid" panels and are now vying for the spotlight. 〇 Why is "lightweight" gaining attention now? Conventional solar panels are heavy, and due to structural limitations, there have been many cases where they cannot be installed on roofs. This has been particularly true for small to medium-sized factories, warehouses, and hospitals in urban areas, where weight restrictions have become a barrier to installation. This is where the "lightweight and flexible" new panels come into focus. 〇 The key to full-scale development towards 2040: "Perovskite solar cells" The film-type perovskite solar cells are expected to drive future growth. - If you're considering installation, now is the chance! Kenneth Energy Development supports companies in reducing electricity costs and achieving environmental management through industrial rooftop solar power generation.

The latest "Calcophyllite Solar Cells" have been installed at the international terminal building of Fukuoka Airport. These solar cells are characterized by their ultra-lightweight and thin design, weighing only 0.8 kg per square meter. Because they can be installed without putting a burden on the roofs of buildings and facilities, they are attracting attention as a technology that greatly expands the possibilities of solar power generation in the future. The installation and demonstration experiments will be conducted by Kyuden Mirai Energy. The solar cells are provided by PXP Corporation, the construction is handled by Kyudenko, and the installation support is provided by JGC Corporation, with performance and construction feasibility being verified from December 2025 to February 2026. Particularly in places like airports, the shape of the roof and the impact of reflected light are also important verification points. This time, practical usability will be confirmed, including those factors. Fukuoka Airport is also planning an exhibition to introduce the details of the experiment. The day may soon come when lightweight and high-performance solar cells become the "norm" in future buildings.
