Keep lights, fans and phones going
Start with a small known load. You may not need the complexity of a full roof redesign.

Fit first. Parts second.THE OPEN ROAD POWER MAP / Interactive buyer planner
More campsite. Less generator.
The view is spectacular. The campground hookups are nonexistent. Good solar means the fan keeps spinning and the fridge does not become tomorrow’s problem. Roofs are small, trees are tall and every amp-hour matters. Build a solar plan around where your RV actually parks.
Size the energy before you shop
Enter a daily energy budget in watt-hours, realistic peak sun hours, how many days of battery-only reserve you want, and your largest expected simultaneous running AC load. This quick estimate uses 75% solar derating, 80% usable storage, and a 25% inverter sizing allowance. It is an educational screen, not a verified design or a promise of compatibility.
Try an example, then edit your numbers:
Estimated panel nameplate500 WDaily Wh ÷ (sun hours × 0.75); rounded upward. Site shade and seasons change output.
Nominal battery capacity2.9 kWhDaily Wh × reserve days ÷ 0.8. Real usable energy varies by product and temperature.
Illustrative inverter continuous rating1,300 WRunning load × 1.25. Motor-start surge must be verified separately.
Do not use this estimate to size life-safety equipment or make electrical connections. Confirm actual appliance measurements, manufacturer voltage/current specifications, protective devices and local codes. For outages, fuel-generator safety and approved transfer equipment are separate considerations.
Three ways to make it work
Fridge, work gear and variable shade
Battery days and portable panel placement can matter as much as rooftop watts.

Calculate travel-day charging, parked shade, rooftop area, cable routing and battery reserve for a string of cloudy campsites.
RV roofs, alternators and battery bays have vehicle-specific limits. Follow the vehicle and equipment manufacturers’ installation requirements.

Check the fit before checkout
- List actual loads in watts and daily operating hours.
- Check peak and starting loads separately.
- Verify battery usable capacity and charging temperature limits.
- Check panels, controller, charger, cables and connector compatibility.
- Price protective equipment, mounts and professional installation where needed.
