A 300 amp-hour camper battery, for instance, would need around 300 watts of solar power. Also keep in mind that solar panels experience a 75-90% drop in efficiency on cloudy days, so it's good to have slightly more than you need when it comes to solar power (about a 20% cushion, if possible, to account for less-than-ideal conditions).
A 100W solar panel in good sun provides about 25–30Ah per day (after real-world losses). Using this estimate: From our example, the caravan needs around 60Ah/day, so a 200W solar kit would just cover it. To allow for cloudy days, extra devices, and battery inefficiency, going up to 300W or 400W is a safer choice for reliability.
Each appliance uses a certain number of watts (W) and will be run for a certain number of hours per day. Example: In this example, the caravan needs around 720Wh per day (0.72kWh). Your solar panels don't power devices directly — they charge your batteries. Most caravan setups use 12V batteries, so we convert watt-hours into amp-hours (Ah).
We tested 100+ watt solar panels from Goal Zero, Jackery, Ecoflow, BigBlue, Renogy, and more to charge your off-grid power station. The right solar panel extends a power station capacity from limited to potentially delivering perpetual power (so long as the sun is out!).
