The STAR 495W N-Type 16BB Bifacial Frameless Solar Panel (CleanEdge, GSN8R54T(H)495) is the better rigid solar panel overall, rated 4.4 to 4.0. The STAR 495W N-Type 16BB Bifacial Frameless Solar Panel (CleanEdge, GSN8R54T(H)495) leads on value. The STAR 495W N-Type 16BB Bifacial Frameless Solar Panel (CleanEdge, GSN8R54T(H)495) costs $260 less ($339.99 vs $599.99).
A cheap-per-watt, very large bifacial panel for home rooftop or ground-mount arrays where the installer can confirm the electrical specs first. Not for RVs, vans or anyone who needs a datasheet up front.
Amazon $339.99A large-panel pair for a cabin, shed or ground-mount array with a high-voltage MPPT controller. Too big and too high-voltage for most van and small RV setups.
