Topsky Energy TP120-400M/MB-9 400W PERC Monocrystalline Solar Panel
Model TP120-400M/MB-9 | PERC | 108 Half-Cell | Monocrystalline | 1500V System Voltage
Product Overview
The Topsky Energy TP120-400M/MB-9 is a high-efficiency solar panel designed for dependable power generation. It uses PERC technology and delivers up to 400 Wp output with 20.5% efficiency. Its 108-cell structure supports stable performance across demanding residential and commercial applications. The module is built for long service life, with a 12-year product warranty and a 12-year power warranty. It is also suited for projects that value compact dimensions, solid electrical performance, and consistent energy production.
Key Benefits
High output performance: Delivers 400 Wp maximum power for efficient solar energy production.
Strong module efficiency: The 20.5% efficiency rating supports strong energy harvest in limited roof space.
Reliable cell design: The 108-cell layout supports balanced electrical output and stable field performance.
Durable construction: Tempered anti-reflection glass and EVA encapsulation help protect the module in outdoor use.
Wide system compatibility: A 1500V maximum system voltage supports modern string configurations and project flexibility.
Compact and practical size: The 1722 x 1134 x 30 mm format supports easier installation on many mounting systems.
How It Works
This solar panel converts sunlight into usable electricity through its PERC cell architecture. Light strikes the tempered glass surface, then passes to the photovoltaic cells beneath. Those cells generate direct current for use in a solar array. The module is engineered to maintain performance across a wide temperature range. Its electrical ratings support consistent energy capture under standard operating conditions. The design also helps reduce efficiency losses during real-world operation.
PERC cell conversion: PERC technology improves light capture and electrical conversion efficiency. This helps the module produce more power from the same sunlight exposure.
Electrical output delivery: The panel generates 31.01V at maximum power and 12.9A current under rated conditions. These values support stable string design and predictable system behavior.
Environmental durability: The module operates from -40 to 85 °C and includes temperature coefficients for key measurements. This allows performance to remain more consistent in changing weather.
