FAQ

How does white underlay fabric help bifacial solar panels?

The white surface reflects sunlight upward toward the rear side of bifacial panels, allowing the panels to capture light from both sides more effectively.

Does this fabric increase solar panel efficiency?

Reflective ground cover can help increase the amount of light reaching the rear of bifacial solar panels. Actual performance gains vary depending on the solar system, installation, location, and environmental conditions.

Does solar panel underlay fabric help control weeds?

Yes. The heavy-duty fabric creates a ground barrier beneath solar panels that helps suppress weed growth and reduce vegetation maintenance.

Does water drain through the fabric?

Yes. The non-woven fabric is permeable and has a flow rate of 110 GPM per sq ft, allowing water to pass through instead of pooling on the surface.
