Q: How much extra power does the bifacial design produce?

A: Typically 5-25% additional energy depending on ground albedo (reflectivity). White surfaces: 15-25% gain. Grass/soil: 5-10% gain. The gain is automatically calculated in total energy output.

Q: Can I install bifacial panels on a regular roof?

A: Bifacial panels perform best with space behind them for reflected light. On dark flat roofs, gain is minimal (3-5%). For sloped residential roofs, standard monofacial panels may be more cost-effective.

Q: Do they need special mounting?

A: Standard mounting compatible, but for maximum bifacial gain use mounting that minimizes rear shading (edge clamps, elevated rails). Torque tubes for trackers are ideal.

Q: What's included in the 25-year warranty?

A: Year 1: 98% output. Year 2-25: 0.45% annual degradation. Guaranteed 87% output at year 25. Product workmanship warranty: 12 years.
