Universal Solar WXS320P7-US 320W Polycrystalline 72-Cell Solar Panel
Model WXS320P7-US | Polycrystalline Silicon | 72 Cells | Monocrystalline/Bifacial Not Specified | 1000V System Voltage
Product Overview
The Universal Solar WXS320P7-US is a 320W polycrystalline solar panel built for dependable energy production and long-term value. It uses 72 multi-crystalline silicon cells to deliver stable performance in residential and commercial solar installations. The module is designed with a 1000V maximum system voltage, MC4 connectors, and an IP65 junction box for practical field integration. With a 5-year workmanship warranty and long power coverage, this panel offers a balanced mix of durability, efficiency, and installation flexibility. Its robust frame, tempered construction, and controlled temperature behavior support consistent operation in demanding environments.
Key Benefits
Reliable 320W Output: Delivers strong rated power for dependable daily generation in a wide range of solar projects.
Polycrystalline Cell Design: The multi-crystalline silicon construction supports proven performance and broad deployment compatibility.
Built for System Integration: A 1000V maximum system voltage and 15A fuse rating support straightforward system design.
Weather-Ready Construction: The IP65 junction box, TPT back cover, and EVA encapsulant improve outdoor durability.
Long-Term Warranty Support: Coverage includes 5 years for materials and workmanship, plus extended power retention protection.
How It Works
The WXS320P7-US converts sunlight into usable electricity through 72 polycrystalline silicon cells. When sunlight reaches the cells, electrical current is generated and routed through the panel’s internal connections. The module is designed to perform at standard test conditions, with measured output defined by voltage, current, and power ratings. Its electrical characteristics help system designers predict string behavior and inverter compatibility. The panel’s temperature coefficients show how output changes as operating conditions shift. Its protective construction helps maintain dependable operation over time. The MC4 connector, 1200mm cable length, and IP65 junction box support fast field installation and reliable electrical connection.
Solar Conversion: Sunlight activates the polycrystalline cells and produces direct current electricity. The 72-cell layout supports stable energy harvesting across the module surface.
Electrical Delivery: Power is delivered through the listed operating voltage and current values. These specifications help define how the panel performs within a series string.
Protected Field Use: The junction box, cable system, and durable encapsulation support outdoor operation. The design helps the module handle temperature variation and installation stress.
