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 30 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 30 W × 0.75 × 5.2 h = 117 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.
