REC Alpha Pure-RX 460W Solar Panel vs Sungold Power 560W Bifacial PERC Solar Panel

The REC460AA is the better panel for a residential rooftop: higher efficiency in a smaller, lighter module, heterojunction cells with strong low-light and heat performance, and a warranty that covers labor. The Sungold 560W is a bigger, heavier bifacial PERC panel aimed at ground mounts, carports and canopies, where its extra wattage per panel matters more than efficiency per square foot. Owners rate both highly, but the REC has far more ratings behind it and a documented degradation curve; the Sungold's 95% five-year output warranty is far weaker than REC's 25-year coverage.

• Choose the REC460AA if you have limited roof space, want microinverter or optimizer compatibility, or care about long-term degradation and labor-covered warranty.
• Choose the Sungold 560W if you are building a ground mount or canopy array with room for large panels and want more watts per panel.
