Voltec Solar 355W Monocrystalline Solar Panel
Model 355 | Monocrystalline | 126 Half-Cell | Monofacial | 1000V System Voltage
Product Overview
The Voltec Solar 355W is a monocrystalline solar panel designed for reliable everyday energy production. It combines compact dimensions with solid performance for residential and commercial rooftop systems. With a 355 Wp rating and 18.57% efficiency, it delivers dependable output in a space-saving format. The panel uses 126 half-cells for improved energy capture and stable operation. It also features tempered glass, an aluminium frame, and IP68 protection for long-term durability. The product is built for broad climate compatibility and a wide operating temperature range. Its French origin and recyclable design add further value for sustainability-focused installations.
Key Benefits
High power output: The module delivers 355 Wp for strong rooftop generation.
Space-efficient design: Its 18.57% efficiency supports better energy yield from limited roof space.
Durable construction: Tempered glass and an aluminium frame help support long service life.
Weather-ready protection: The IP68 junction box improves resistance in challenging outdoor conditions.
Long-term value: A 25-year product warranty and strong performance retention support investment confidence.
How It Works
This monocrystalline panel converts sunlight into electricity through high-quality cells arranged in a 126 half-cell layout. The cell design helps reduce resistive losses and supports stable power delivery throughout the day. Under standard test conditions, the panel reaches its rated 355 Wp output. In real operating conditions, temperature coefficients help explain how performance changes as heat rises. The module is built to keep operating safely across a wide temperature range from -40 °C to 85 °C. Its construction also supports consistent performance in demanding rooftop environments.
Photovoltaic conversion: Sunlight strikes the monocrystalline cells and generates direct current electricity. The 126 half-cell layout helps the module work efficiently and reliably.
Thermal performance control: The temperature coefficients show how output changes under hotter conditions. This helps installers estimate production more accurately across seasons.
System integration: The panel connects with MC4-compatible hardware and supports up to 1000V system voltage. This makes it suitable for standard PV array configurations.
