A strong value for a 400 W ground mount, shed roof or large RV roof, and a good match for power stations with a 60 V solar input. Mostly sold as a pair on Amazon.
Amazon $319.99 Callsun $319.99A large bifacial panel with a longer warranty than most, for a home rooftop, shed or ground-mount array on a 24 V or 48 V system or a grid-tie inverter. Too big and too high-voltage for most RV and van setups.
