Topsky Energy TP120-420M/MB-9 400–420W PERC Monocrystalline Solar Panel
Model TP120-420M/MB-9 | PERC | 108 Half-Cell | Monocrystalline | 1500V System Voltage
Product Overview
The Topsky Energy TP120-420M/MB-9 is a high-efficiency solar panel built for reliable daily energy production. This PERC module delivers a power range of 400 to 420 Wp, making it suitable for residential and commercial systems. Its 21.5% maximum efficiency supports strong output in limited roof space. The module uses 108 half-cells for improved performance and stable energy harvesting. Durable materials, including tempered anti-reflection glass and an anodized frame, support long-term outdoor use. With a 1500V maximum system voltage, it is designed for modern photovoltaic installations.
Key Benefits
High power range: The module offers 400 to 420 Wp, supporting versatile system design and strong energy generation.
Strong efficiency: Up to 21.5% panel efficiency helps maximize output from available installation space.
Stable PERC performance: PERC cell technology improves light capture and supports dependable electrical conversion.
Durable construction: Tempered anti-reflection glass and an anodized frame help the panel handle outdoor conditions.
Low power loss risk: The 0 to +5% power tolerance provides positive output flexibility during installation and operation.
How It Works
This solar panel converts sunlight into usable electricity through photovoltaic cells. The PERC structure improves light utilization and supports better output across changing conditions. Half-cell construction helps reduce internal resistance and improves performance consistency. The panel then feeds generated direct current into a compatible inverter for conversion to usable AC power. Its electrical design supports stable operation at elevated system voltages, which helps it integrate into larger solar arrays. The durable build protects internal components while the module continues producing power over many years.
PERC cell conversion: PERC technology captures more light behind the cell surface. This supports stronger energy output from the same sunlight.
108 half-cell design: Half-cells reduce resistive losses across the module. They also help improve output stability under partial shading.
System integration: The panel produces direct current at operating voltages suited to modern arrays. Installers can connect it within approved 1500V system designs.
