Topsky Energy TP120-405M/MB-9 405W PERC Monocrystalline Solar Panel
Model TP120-405M/MB-9 | PERC | 108 Cells | Monocrystalline | 1500V System Voltage
Product Overview
The Topsky Energy TP120-405M/MB-9 is a high-efficiency 405W PERC solar panel built for reliable daily energy generation. It combines a compact 108-cell layout with strong electrical performance and a durable mechanical structure. The module is designed for rooftops and commercial systems that need stable output and long service life. With 20.7% efficiency, it delivers strong energy yield in a practical footprint. Its 12-year product warranty and 12-year power warranty add confidence for long-term use. The panel also features a low degradation profile, which supports dependable performance over time.
Key Benefits
High Power Output: The module delivers up to 405Wp for strong system performance.
High Conversion Efficiency: A 20.7% efficiency rating supports better energy capture from available sunlight.
PERC Technology: PERC cell technology helps improve light absorption and overall module output.
Stable Long-Term Performance: The panel is designed for controlled degradation and consistent energy production.
Durable Build Quality: Tempered glass, EVA encapsulation, and an anodized frame support lasting outdoor use.
How It Works
The TP120-405M/MB-9 converts sunlight into usable electricity through advanced PERC monocrystalline cells. Light enters the module through anti-reflection tempered glass, which helps reduce surface losses. The cells then generate direct current electricity, which can be used by a compatible inverter or solar power system. Its electrical design supports efficient voltage and current delivery under standard test conditions. The robust frame and encapsulation layers protect the cells from weather exposure. This construction helps maintain stable operation in varied environments and supports long-term solar production.
Light Capture: Anti-reflection coated tempered glass improves incoming light transmission. This helps the cells absorb more sunlight during daily operation.
Power Conversion: The PERC cell structure converts sunlight into electrical energy efficiently. The module is rated at 405Wp for strong output across installations.
System Integration: The panel delivers electrical values suited to common solar configurations. Its 1500V system voltage supports modern string design requirements.
