The EPOCH 430W N-Type 16BB Bifacial Rigid Solar Panel (Epoch-400SPP-1-N) and the STAR 430W N-Type Bifacial Double-Glass Solar Panel (SR-SP-430W-N-1, UL 61730) are evenly matched, rated 3.9 and 3.9. The EPOCH 430W N-Type 16BB Bifacial Rigid Solar Panel (Epoch-400SPP-1-N) costs $10 less ($269.99 vs $279.99).
A low-cost large bifacial panel for a home rooftop, shed or ground-mount array on a 24 V or 48 V system with an MPPT controller. The thin paperwork and unstated warranty make it a price play rather than a long-term pick.
Amazon $269.99A low-cost 430 W bifacial panel for a home rooftop, shed or ground-mount array, if you can get the electrical specs from the seller before buying. Buyers who want a datasheet and stated warranty should look at JJN’s or Callsun’s large panels.
