Silfab SIL-440 QD Solar Panel

The Silfab Solar SIL-440 QD solar panel is a high output residential module engineered for strong performance, durability, and long term reliability. Designed and assembled in North America, this panel delivers dependable energy production while maintaining a compact form factor suitable for a wide range of residential roof layouts.

The SIL-440 QD balances higher wattage output with proven manufacturing quality, making it a strong option for homeowners seeking efficient solar production without sacrificing reliability.

High Output Residential Performance

With a 440 watt power rating, the SIL-440 QD provides excellent energy production per panel. Higher wattage output allows homeowners to reduce the total number of panels required to meet energy goals, supporting efficient system layouts and cleaner roof aesthetics.

This performance level is well suited for both standard and higher demand residential installations.

Advanced Cell and Module Design

Silfab panels are engineered to perform reliably under real world conditions. The SIL-440 QD uses advanced cell technology designed to maintain consistent output during temperature fluctuations, partial shading, and varied roof orientations.

This design approach supports stable daily production and dependable long term energy yield.

Built for Long Term Durability

Residential solar panels must withstand decades of outdoor exposure. The SIL-440 QD is built with robust materials and quality control standards intended to support long service life and reliable operation.

Its construction helps protect against common sources of degradation, supporting consistent performance over time.

Integration with Modern Solar Systems

The SIL-440 QD solar panel is compatible with a wide range of inverter and microinverter systems commonly used in residential solar installations. When paired with panel level power electronics, the system can optimize performance across complex roof designs and partial shading conditions.

The panel integrates cleanly with home battery systems and whole home energy solutions when properly designed.

Warranty and Performance Assurance

Silfab Solar panels are backed by manufacturer warranties that cover product quality and long term power output. The SIL-440 QD includes warranty protections designed to support confidence in system performance and energy production over the life of the installation.

These warranties help protect homeowner investment and system reliability.

Designed for Scalable Home Energy Systems

As household energy needs grow due to electrification, battery storage, or electric vehicle charging, solar systems must be able to scale. The SIL-440 QD supports system expansion when design conditions permit, allowing additional panels to be added over time without full system replacement.

This scalability supports long term energy planning and flexibility.
