Introduction
In 2026, a photovoltaic system is more than just panels on a roof; it is a complex energy harvesting ecosystem. At CHASUN, we categorize these systems based on their relationship with the utility grid and storage.
The Three Core System Types
-
On-Grid (Grid-Tied) System: The most common for urban areas. It feeds excess energy back to the grid.
-
Off-Grid System: Essential for remote regions in Africa and South America. It relies entirely on batteries and CHASUN high-efficiency modules.
-
Hybrid System: The best of both worlds, providing grid stability and battery backup.
Technical Metric: Performance Ratio (PR)
To evaluate the “health” of a CHASUN PV system, we use the Performance Ratio formula:
Where $E_{out}$ is the actual energy yield, and $PR$ represents the efficiency of the system after subtracting energy losses (e.g., heat, wiring).
Conclusion
Whether you are pursuing ROI or energy independence, CHASUN engineers customize the system architecture to fit your local irradiance data.
