Same watts.
Different electrical fit.
Compare the figures that change an array—not just the number printed largest on the box. A higher voltage or current is not automatically better; it must fit the station’s documented input.
Choose two exact panels.
No synthetic winner: voltage headroom, current limits, portability and cable paths solve different setup problems.
200W N-Type Bifacial
Fixed vehicle, shed or cabin arrays that suit its higher operating voltage.
220W Bifacial
Foldable, higher-output charging for compatible portable power stations.
This gap multiplies with every panel placed in series and grows again in cold conditions.
This gap matters most when strings are placed in parallel or an input has a tight current limit.
