The Adoption of Next-Generation Solar Cells in NiiGata Prefecture

NiiGata Prefecture is heading towards a more sustainable future by adopting innovative solar technology. Recently, it announced the approval of the 'Next-Generation Solar Cell Demonstration Support Grant Program (Reiwa 7 Year)' aimed at enhancing the use of next-generation solar cells within its snowy regions. This initiative notably includes a demonstration trial at the NiiGata Prefectural Office, marking a significant step toward addressing renewable energy challenges in areas that experience heavy snowfall.

Details of the Next-Generation Solar Cell Grant Program

The objective of the 'Next-Generation Solar Cell Demonstration Support Grant Program' is to facilitate the introduction of renewable energy sources by providing financial support for demonstrative projects that utilize advanced solar technologies. This program is vital for achieving a carbon-neutral society by 2050, especially in regions with challenging weather conditions like NiiGata.

Overview of the Demonstration Project

The project features the innovative PXP-developed copper sulfide solar cells, known for being thin, lightweight, and flexible. These characteristics make them particularly suitable for installation on existing structures while ensuring efficient energy conversion.

Key Objectives:

1. To demonstrate the effectiveness of the flexible copper sulfide solar cells in snowy environments of NiiGata.
2. To investigate challenges for the large-scale adoption following the trial phases, with a focus on practical deployment in the region's existing infrastructure.

Details of the Demonstration Installations:

• - Location: NiiGata Prefectural Office, 3rd Floor East Corridor, NiiGata City.

Purpose: To analyze the installation and operating conditions of copper sulfide solar cells while utilizing their specific traits for energy generation.
Start Date: November 26, 2025.

• - Company: Sakazume Lumber Company (part of SOLABLE Group)

Purpose: To assess installation methods for diverse building shapes, including trapezoidal roofs and tent structures, as well as to evaluate the impact of reflected sunlight from snowy surfaces.
Start Date: Expected to commence around mid-December 2025.

Future Prospects

With the goal of establishing a more sustainable society, SOLABLE aims to leverage the findings from this demonstration project to expand its initiatives across Japan. Further installations of the demonstration system are scheduled for multiple structures at Sakazume Lumber Company, emphasizing the potential for broader implementation of next-generation solar technology across the snowy regions of Japan. By optimizing the use of copper sulfide solar cells, SOLABLE endeavors to present a viable solution to the complexities brought on by seasonal weather patterns, ultimately promoting the use of renewable energy sources nationwide.
