Canadian Solar CS7N-660MS 660W PERC Monocrystalline Solar Panel
Model CS7N-660MS | PERC | 132 Half-Cell | Monocrystalline | 1500V System Voltage
Product Overview
The CS7N-660MS is a high-output solar panel designed for demanding commercial and utility-scale installations. It uses proven PERC monocrystalline technology to deliver strong performance and dependable long-term value. With a rated power of 660 Wp and module efficiency of 21.2%, it is built for projects that need high energy density and efficient rooftop or ground-mount use. The panel combines a 132-cell layout, tempered anti-reflection glass, and an anodized aluminium frame for stable field performance. It also supports a 1500V system, which helps reduce balance-of-system complexity in larger arrays.
Key Benefits
High power output: The module delivers 660 Wp, making it suitable for space-conscious projects.
Solid efficiency: Its 21.2% efficiency helps maximize energy generation from available surface area.
PERC monocrystalline design: PERC cell technology is used to improve light capture and overall power production.
Durable construction: Tempered glass, an anodized aluminium frame, and IP68 protection support reliable operation.
Lower system complexity: The 1500V maximum system voltage supports efficient design for larger solar installations.
How It Works
The CS7N-660MS converts sunlight into electricity through mono-crystalline PERC cells arranged in a 132-cell format. Incoming light is absorbed by the cells, and the PERC design helps capture more usable energy from each ray. This improves electrical output under everyday operating conditions. The panel is engineered for consistent voltage and current performance, which helps system designers match strings more accurately. Its low degradation profile supports steady generation over time, while the durable structure protects internal components in harsh weather. Together, these features create a module suited to commercial arrays that need strong energy yield and dependable operation.
PERC cell conversion: The PERC structure captures more light and converts it into electrical current. This helps improve output in real-world conditions.
String-ready electrical behavior: The module provides stable operating voltage and current values. This makes it easier to design efficient arrays.
Weather-resistant protection: The tempered glass, sealed junction box, and IP68 rating support long-term outdoor use. These parts help maintain performance in challenging environments.
