Good fit if

  • You want to recharge a power station from sunlight during a multi-day outage
  • Your station's solar input accepts this panel's voltage, current and connector

Look elsewhere if

  • You have not checked your station's solar input limits
  • You need guaranteed charging in winter or under heavy cloud

How much energy it adds

A 420 W panel produces its rated power only in ideal conditions. Heat, sun angle and cable losses reduce real output; we assume 75% of rating.

Wattstanding calculationWattstanding calculation — Wh/day = panel watts × 75% × peak sun hours. For example 420 W × 0.75 × 5.2 h = 1,638 Wh. Sun-hour figures are approximate annual averages; winter and cloudy days are much lower.

Pairing it with a power station

A power station accepts solar input only within its own voltage and current limits. Compare this panel's figures with the station's stated solar input before connecting anything.

  • Voc 48.9 V
  • Vmp 40.3 V
  • Isc 11.4 A
  • Imp 10.4 A

Fit check before you buy

Checks to make against the power station you plan to charge.

  • ?ConnectorMatch the panel's connector to the station's cable or adapter.
  • iSpace and anglePanels need open sun and an angle toward it; shade on part of a panel can cut output sharply.
