Short answer: match the panel's Voc and connector to your power station, pick 100–200 W for most campers, and choose folding panels for portability or a rigid panel on a stand if weight doesn't matter.
| If you need… | Look for |
|---|---|
| Phone/power bank only | 20–60 W USB panel |
| Recharge a 500 Wh station in a day | ~100–200 W |
| Recharge a 1 kWh station in a day | ~200–400 W (charge time calculator) |
| Two panels on one station | Check series Voc under the station's max (calculator) |
Safety: These are general estimates, not a design. Follow your equipment manufacturer's instructions and local electrical code, and consult a qualified electrician for anything connected to shore power, a house, or high-current batteries.
Divide the Wh you want to refill by sun hours × 0.75. A 1,000 Wh station from about 20% needs roughly 200–250 W over a 4–5 sun-hour day.
Often yes, with an MC4 adapter, if voltage and current stay within the station's limits.
