Solar Recharge Time Calculator: How Long to Refill a Power Station From the Sun
The box says “full in 2 hours of sun.” The 200W panel makes 130W at the campsite, the station only takes what its charge controller allows, and the sun is only strong for four hours. This solar charging calculator shows the real number for any station and panel we track: hours of peak sun to full, days at your location's sun, and whether a day's harvest covers what you draw at night.
Panel output is rated watts × 0.65, the planning factor published across our solar guides; the station's max solar input is the manufacturer's ceiling. Nothing here is measured on a bench. Method: how we research.

0.65 is the planning baseline. Cold, clear, tracked panels reach 0.75–0.80; hot, hazy, fixed-flat panels drop to 0.55–0.60.
4. What you use per day (optional)
Anker SOLIX C1000 Gen 2 · 1 × Anker SOLIX PS200 Solar Panel · 4.5 peak sun hrs/day
7.9 hrs of peak sun to full
200W rated × 0.65 = 130W in the field. 1024Wh ÷ 130W = 7.9 hrs from empty — expect 10–20% longer, because the charge controller tapers current near full.

Headroom: this station accepts 600W, so it would take about 5 of these panels (at × 0.65) to hit the ceiling. Until then, every panel added shortens the recharge.
Watts only. Whether the panels are inside the station's MPPT voltage window is a separate check — see why solar generators charge slower than advertised.

- How many solar panels do I need? — the sizing formula, worked for 300, 500, and 800Wh days at 4 and 6 sun hours.
- Solar panel STC rating vs real output — where the 0.65 comes from and when to use 0.55 or 0.80 instead.
- Why your solar generator charges slower than advertised — MPPT voltage windows and amperage caps, the constraints this calculator can't see.
- Solar generator bundle vs buying separately — whether the panel in the box is the panel you'd choose.
