210-66 — 700–730 W

The cheapest watt in the range. 2384 mm tall, 37.5 kg, and the highest current — which is also its main risk.

210-66 700–730 W N-type TOPCon bifacial module
210-66 · 700–730 W · bifacial glass-glass
  • Lowest $/W of the three formats
  • Isc 18.56 A (20.42 A with bifacial gain) — check your MPPT input limit
  • 132 half-cells, 210 × 105 mm

Fit

Where this format makes sense

Good fit. Ground-mount and large roofs where you have the width and long strings are acceptable.
Poor fit. Inverters with a 30 A per-MPPT limit — with bifacial gain the current exceeds it, so this format must run one string per MPPT, not two.
