About This Product
The Silfab Solar SIL580-XMPLUS 580W Bifacial Solar Panel is a high-output photovoltaic module designed for commercial, industrial, and large-scale solar installations. Part of Silfab Solar’s XM+ series, this 580W panel uses 144 half-cut solar cells and a bifacial design to generate electricity from direct sunlight on the front and reflected light reaching the rear. It features a silver aluminum frame, transparent backsheet, and factory-installed Stäubli MC4-EVO2 connectors. With a maximum system voltage rating of 1500V DC, the module is suited to appropriately engineered high-voltage PV arrays.
Who This Product Suits
The Silfab Solar SIL580-XMPLUS is suited to commercial solar contractors, EPC installers, and project developers looking for high-wattage bifacial modules. It is particularly useful for ground-mounted arrays, commercial rooftops, and installations where the mounting arrangement and surrounding surfaces allow reflected sunlight to reach the rear of the module. Its 580W output can help installers achieve a specified DC array capacity using fewer modules than lower-wattage alternatives. Installers should verify structural suitability, inverter compatibility, mounting requirements, and NEC-compliant electrical design before installation.
Specifications Explained
- 580W Rated Output: The module’s front-side power rating under standard test conditions, used when calculating PV array capacity.
- 144 Half-Cut Cells: A half-cell module configuration designed to support efficient current collection and reduce internal resistive losses.
- Bifacial Construction: Allows the rear of the panel to collect reflected and scattered sunlight. Additional energy production depends on installation conditions and rear-side irradiance.
- Transparent Backsheet: Permits light to reach the rear-facing solar cells while providing a protective module construction.
- 1500V DC Maximum System Voltage: Supports appropriately designed high-voltage PV systems, subject to equipment ratings and applicable NEC requirements.
- Stäubli MC4-EVO2 Connectors: Factory-supplied PV connectors for integration with compatible wiring and connection equipment.
- Silver Frame: Provides a rigid mounting structure for approved solar racking systems.
- Warranty Coverage: Supplier-listed coverage includes a 12-year product warranty extendable to 25 years subject to registration and applicable conditions, together with a 30-year linear performance warranty. Warranty eligibility and terms should be confirmed against the manufacturer’s documentation.
