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 module delivers 580W of rated front-side power using a 144 half-cell bifacial design that can capture sunlight from both the front and rear surfaces.
The panel features a silver aluminum frame, transparent backsheet, and factory-installed Stäubli MC4-EVO2 connectors. It incorporates USA-sourced encapsulant and backsheet materials and includes domestic content that may contribute toward eligibility for applicable federal domestic content incentives, subject to IRS requirements and project qualification.
Who This Product Suits
The Silfab Solar SIL580-XMPLUS is suited to commercial rooftop arrays, ground-mounted solar systems, and larger installations where high-output modules help achieve the required system capacity with fewer panels.
Its bifacial construction is particularly useful for installations with reflective ground surfaces, elevated mounting arrangements, or other conditions that allow sunlight to reach the rear of the module. It is also suitable for US solar developers and installers evaluating domestic content requirements for eligible projects.
Installers should confirm structural compatibility, inverter voltage limits, mounting requirements, and NEC-compliant electrical design before specifying this module.
Specifications Explained
- 580W Rated Output: Front-side nameplate power under standard test conditions, with potential additional energy production from rear-side irradiance.
- 144 Half-Cell Design: Uses half-cut photovoltaic cells to support efficient current collection and module operation.
- Bifacial Construction: Allows the rear surface to generate additional electricity when sufficient reflected or transmitted sunlight is available.
- Transparent Backsheet: Supports rear-side light collection while providing a protective layer for the module.
- 1500V DC Maximum System Voltage: Supports appropriately engineered high-voltage PV strings, subject to equipment ratings and NEC requirements.
- Stäubli MC4-EVO2 Connectors: Factory-fitted connectors for PV wiring, requiring compatible listed mating connectors and proper installation practices.
- 25-Year Manufacturer Warranty: Provides long-term manufacturer warranty coverage under the applicable warranty terms.
- 30-Year Performance Warranty: Specifies minimum warranted output of 98% after year one, 94.7% after year twelve, 90.8% after year twenty-five, and 89.3% after year thirty.
- Domestic Content: Incorporates USA-sourced encapsulant and backsheet materials that may support domestic content qualification when applicable IRS requirements are satisfied.
