The hot spring resort hotel "Hotel Listel Hamanako" (Hamamatsu City, Shizuoka Prefecture: General Manager Yukihiro Yamaki) built on the lake shore, has installed 80 state-of-the-art, lightweight silicon panels manufactured by Ace Network Co., Ltd. on its roof. From April 2026, we have started operating on self-generated power.
This system covers approximately 12% of the hotel's electricity usage. It enables us to power the large public bath lighting, open-air baths, and sauna equipment with clean energy. Through this, we will realize an evolution into an "environmentally friendly resort."
### ■ Background of the New Installation: Overcoming the "Cannot Install" Challenge with Latest Tech
While promoting eco-activities to protect the rich natural environment of Lake Hamana, it was difficult to install conventional heavy solar panels on the roof due to load-bearing issues.
However, by adopting Ace Network's latest panels, we realized a "direct installation" that requires no foundation work. While suppressing the burden on the building, we have transformed previously unutilized space into a power generation hub for environmental protection.
### ■ Features of This System: "5 Strengths" Optimal for Nature-Rich Resorts
- **Industry's highest class power generation**: Despite being thin, it achieves a high output of 520W per panel, totaling 41.6kW.
- **Does not spoil the scenery**: Installation requires no height and suppresses light reflection, protecting the beautiful scenery of Lake Hamana.
- **Resilient to typhoons and disasters**: Extremely thin and lightweight, drastically reducing the risk of being blown away by the strong winds unique to Lake Hamana.
- **High durability**: Lifespan of 25 years. Flexible yet strong, resistant to cracking even from impacts like hail.
- **Rarity of introduction**: Being the latest model, there are few introduction examples nationwide; it is a system that will become the next generation standard.
### ■ Value Provided to Customers: The "Totono'u" (Tuning) Experience with Sunlight
