Upsolar UP-M355P 355W Polycrystalline Solar Panel
Model UP-M355P | Polycrystalline | 144 Cells | Monofacial | 1500V System Voltage
Product Overview
The Upsolar UP-M355P is a polycrystalline solar panel designed for dependable performance and long service life. It delivers a maximum power rating of 355 Wp and reaches a module efficiency of 17.9%. The panel is built with 144 cells, a durable anodized aluminium frame, and tempered anti-reflection glass. Its 1500 V maximum system voltage supports modern solar installations. A 12-year product warranty and 25-year power warranty add long-term confidence. The panel is suitable for projects that need stable output, strong protection, and efficient use of roof or ground space.
Key Benefits
Strong power output: The module provides 355 Wp for reliable energy generation in demanding installations.
Efficient cell design: Its 17.9% efficiency helps maximize energy harvest from available installation space.
Durable construction: Tempered glass, EVA encapsulation, and an anodized aluminium frame support lasting field performance.
Weather resistance: The IP67 junction box and robust components help protect the module in challenging environments.
Long-term assurance: A 12-year product warranty and 25-year power warranty strengthen the investment value.
How It Works
The Upsolar UP-M355P converts sunlight into usable direct current through polycrystalline silicon cells arranged across a 144-cell module layout. Incoming light is absorbed by the cell surface and transformed into electrical energy. The anti-reflection coated tempered glass helps reduce light loss and improves light capture. The module is then supported by an anodized aluminium frame, which helps maintain structural integrity during installation and operation. Its electrical design is optimized for steady output under real-world conditions. The panel is also built to handle temperature changes and environmental stress over long operating periods.
Light capture: The anti-reflection glass surface helps more sunlight reach the cells. This supports better energy conversion throughout the day.
Power generation: The polycrystalline cells produce electrical output at a rated maximum power of 355 Wp. The module is designed for consistent performance across standard solar applications.
System integration: The MC4 connector, 1500 V system rating, and 20 A fuse rating support practical installation. These features help the panel work within common commercial and residential solar arrays.
