Best RV Solar Kits
For most RV owners the Renogy RV Solar Kit 200W is the one to buy: 200W keeps a house battery topped up on weekend trips, the included controller is a 30A PWM model, and the wiring is included. Step up to the Renogy 400W Premium kit when your measured daily use calls for more panel capacity and an MPPT controller.
- Best for: weekend boondocking with lights, devices, and a vent fan on 200W.
- Check the box: most kits include panels, controller, and wiring but usually not the battery or inverter.
- Skip 200W if: you live in the RV full-time with a residential fridge. Start at 400W so the batteries keep up on cloudy days.
An RV solar kit keeps your house batteries charged when you camp away from hookups, with the panels, controller, and wiring already matched in one box. Below are our favorite kits for beginners, grouped by RV type, plus the simple buying logic to pick the right size the first time.

It is a clean, proven foundation you can expand as your camping gets longer.

Renogy 400W RV Kit
Solar: 400WController: 40A MPPTBest for: Longer off-grid stays
When weekend trips turn into week-long stays, 400W gives you the breathing room a 200W kit lacks. This Renogy package charges a larger battery bank faster and copes far better with cloudy stretches. You need the roof space for four panels, so measure first, but the comfort is real.
What we like
- Comfortable headroom for longer trips
- Charges bigger battery banks faster
- Quality 40A MPPT controller scales well
Worth knowing
- Requires more usable roof space
- Overkill for occasional campers
How to choose an RV solar kit
Start with how long you stay off hookups and what runs while you are there. A weekend camper with lights, a fan, and devices is comfortable on 200W and a single house battery. Full-timers running a residential fridge and more should plan for 400W or higher so the batteries recover on cloudy days.
Check your roof next. A 200W kit fits most RVs even around vents and an AC unit, but 400W needs real estate, so measure before ordering. As always, choose an MPPT controller over PWM, because it harvests more power exactly when light is poor, which is when your batteries need help most.
Who should skip a kit? If your RV came pre-wired for a specific brand, or you want a large custom bank, a tailored build may serve you better. For most RVers, a matched kit plus the right battery is the simplest reliable setup.
Frequently Asked Questions
How much solar does an RV need?
It depends on your rig and how you camp. A weekend RVer running lights, a few devices, and a vent fan is usually fine on 200W. Full-timers who run a residential fridge and more often want 400W or higher so the batteries keep up on cloudy days.
Do RV solar kits include a battery?
Most do not. Kits typically include the panels, charge controller, and wiring, while you add the house battery and inverter. The two Renogy packages here still need a separate battery and a correctly sized inverter for AC loads.
Will a kit fit on my RV roof?
200W usually fits even with vents and an AC unit up top. For 400W, measure your free roof space first, since four panels need more room than people expect. Always confirm panel dimensions against your actual layout before buying.
Can I install an RV solar kit myself?
Many RVers do. The main jobs are mounting the panels, sealing the roof penetrations well, and wiring the controller and battery in order. If your RV has factory pre-wiring for solar, the job gets even simpler. When in doubt, have the AC side checked by a pro.
