Canadian Solar, bifacial solar panel (high-voltage strings)

Canadian Solar 415 W Bifacial Solar Panel

Also written as CS3W-415PB-AG, BiHiKu 415

A 415 W dual-glass bifacial panel from a long-established maker, with a UL 1703 listing named by the seller.

Best for

A ground mount where you want a listed panel from a large maker and have room for a bigger, heavier module.

Strengths and limitations

Strengths

  • UL 1703, IEC 61215, IEC 61730, CEC listed (seller listing).
  • Voc 47.8 V, Isc 11.14 A (Signature Solar); Voc temperature coefficient -0.28%/C (Canadian Solar).
  • 12-year product warranty and 30-year linear power warranty (seller listing, citing the data sheet).

Limitations

  • 62.2 lb and 83.9 x 41.3 in: larger and heavier per watt than the ZNShine.
  • Older poly-crystalline PERC cells.
  • Our string math for an EG4 6000XP: at -20 C each panel reaches about 53.8 V open-circuit, so 8 in series stays under 480 V (3,320 W per string). Check against your own coldest temperature.

What it does not do

  • Match newer panels on efficiency: 18.57% against 22.53% for the ZNShine 440 W.
  • Deliver to a house: Signature Solar ships it only to a business with a loading dock or freight terminal, 10-panel minimum.
  • Work on a 12 V RV system: 47.8 V open-circuit per panel.

Power and travel notes

Real runtime is less than capacity divided by load: conversion losses, battery reserve and temperature all cut into it. Size a battery for your fridge.

Before you buy

  • Panel voltage rises in the cold. Size each string so its open-circuit voltage on your coldest morning stays under the inverter's maximum.

  4. EG4 6000XP user manual, EG4 Electronics (manual copy) (manufacturer), read 2026-11-10. Can run in off-grid only mode. Purely off-grid systems should strongly consider a 2-wire start backup generator for extended cloudy periods (8 to 12 kW diesel recommended, 8 kW minimum per inverter). Two MPPT inputs, 480 V max, optimal 120 to 385 VDC.
