It holds technical advantages particularly in off-grid/microgrid system design and energy dispatch.

II. Cooperation Content & Project Achievements

In 2020, the three parties jointly launched the “Rooftop Off-Grid PV Energy Storage System Joint Development Project” and successfully introduced the LRSS SolarShingle (BIPV integrated solar roofing system).

Main achievements include:

1. Product Innovation – LRSS SolarShingle

   • Utilizes building-integrated PV technology, merging solar modules with roofing materials, balancing power generation functionality with architectural aesthetics.

   • The system has passed UL (Underwriters Laboratories) certification, complying with North America’s stringent safety and performance standards.

   • Features high waterproofing, wind pressure resistance, and high fire resistance ratings, suitable for various rooftop applications.

2. System Integration Capability

   • Provides a complete off-grid solution covering PV power generation, energy storage, and an intelligent management system.

   • Supports modular design, allowing flexible configuration of PV power and storage capacity based on user electricity needs.

3. Market Deployment & Service Model

   • Offers “Home Solar System Kits” and “Rooftop Turnkey Solutions,” covering the entire process from design, installation, and commissioning to operation and maintenance.

   • Multiple demonstration projects have been completed in North America, with stable system operation and positive user feedback.

III. Technical Features & UNIWEALTH’s Value Contribution

In this collaboration, UNIWEALTH is primarily responsible for the energy storage system and energy management, specifically including:

• Lithium Iron Phosphate Energy Storage System: Adopts high-safety, long-life cell solutions combined with an intelligent BMS to optimize system safety and energy efficiency.

• Off-Grid Energy Management Platform: Achieves intelligent coordination of PV generation, storage, and loads, ensuring stable power supply under off-grid conditions.

• Remote Operation & Maintenance Support: Enables system status monitoring and fault alerts via a cloud platform, enhancing the project’s sustainable operational capability.

IV. Project Significance & Industry Impact

This cooperation not only represents technical complementarity and market synergy among the three companies but also signifies a deep integration between China and Canada in the clean energy sector:

• Promotes BIPV technology standardization and commercialization: Provides a high-performance, highly reliable all-in-one solution for the North American rooftop PV market.

• Accelerates off-grid energy system adoption: Particularly in areas with weak grid coverage or high electricity costs, this project delivers significant economic and social value.

• Creates a model for international cooperation: Combines Chinese manufacturing advantages, North American localized services, and European technical standards, offering a replicable model for global energy collaboration.

V. Future Outlook

Looking ahead, the three parties will continue to deepen cooperation in areas such as PV storage systems, microgrids, and community energy sharing, jointly advancing the development and promotion of more innovative energy solutions to support the global goal of achieving net-zero emissions.
