Withmo-supported Reiwa Create Launches Flexible Solar Panel Installation for Older Japanese Homes

Reiwa Create (Headquarters: Fukuoka City, Representative: Kazuya Ehara), in collaboration with Withmo Co., Ltd. (Headquarters: Shibuya-ku, Tokyo, CEO: Kazumu Ogura), is rolling out the next-generation flexible solar panel 'REWA BC SOLAR' for older homes, pre-seismic standard houses, and single-story buildings that have previously struggled with weight and construction limitations. With a lightweight design of 6.5kg per panel and a drill-free installation method, the system can be installed on a detached house in just 2-3 days, making solar power a reality for homes previously considered 'too difficult' for installation.

REWA BC SOLAR takes a fundamentally different approach to the challenges faced by conventional panels. At just 6.5kg per panel, it is about one-third the weight of traditional models. Furthermore, because it is installed using double-sided tape or specialized adhesives, there is no need for drilling into the roof, significantly reducing the risk of leaks. In terms of power generation, it achieves a conversion efficiency of 25.0% using BC cell technology, boasting industry-leading performance. It also supports 'repowering,' where panels can be applied directly over existing old panels, allowing for the restoration of power generation capacity to like-new levels while minimizing removal costs. Full-scale domestic deployment began in January 2026, establishing a supply system that allows for planned implementation by housing and construction companies.
