ONEHO Rooftop PV Solution
A complete rooftop solar solution designed for residential and small commercial rooftops.
A system-level architecture combining rooftop PV modules, distributed conversion, and intelligent monitoring — engineered for real-world rooftop conditions.
Designed to extract maximum value from rooftops
Module-level optimization
Each module operates independently, reducing energy loss caused by shading, orientation differences, and uneven rooftop layouts.
Distributed AC architecture
Power conversion occurs directly at the module level, simplifying system design and improving adaptability to complex rooftop environments.
Integrated system monitoring
Built-in visibility enables both installers and system owners to understand system status and performance from day one.
Rooftop-oriented design
The system is designed to operate reliably across varying rooftop geometries, materials, and installation conditions.
Electrical safety built into the architecture
Rooftop safety is ensured through low-voltage system design, continuous monitoring, and intelligent protection mechanisms.
Low-voltage module-level design
Reduces electrical risk at the source by limiting DC voltage at the module level.
Rapid shutdown capability
Enables fast system shutdown to support rooftop fire safety and emergency response requirements.
Continuous system monitoring
Abnormal behavior can be detected in real time, improving operational awareness and system protection.
Secure data communication
Encrypted data transmission ensures safe communication between devices and cloud platforms.
