- Size from your daily watt-hours, then build the system around it.
- A kit (panels + controller + wiring) is the simplest start; battery is often separate.
- LiFePO4 batteries are the durable default for rigs.
- Mounting and connectors matter as much as the panels.
- Start a bit bigger than you think — fridges and devices add up.
Solar on the road is freedom — quiet power wherever you park. It’s also humbling, because clouds, trees, and short winter days cut output fast. The setups that work are the ones sized honestly and kept simple.
Figure out your daily energy
Everything flows from your daily watt-hours. Add up the fridge, lights, fans, water pump, and device charging you’ll use in a typical day.
- 12V fridge: often 300–600Wh per day
- Lights, fans, and water pump: 100–300Wh per day
- Phones, laptops, cameras: 100–300Wh per day
Panels, battery, and controller
A typical rig pairs a few hundred watts of panels with a LiFePO4 battery and an MPPT controller. A kit bundles the panels, controller, and wiring — but the battery is often bought separately, so check what’s included.
A 200W RV roof kit
Panels, controller, and wiring sized for a camper roof — a tidy way to add solar without sourcing every part yourself.
Want plug-and-play instead of wiring anything? An all-in-one solar generator — a power station plus panels — skips the install entirely.
An expandable all-in-one system
A power station you can grow with extra batteries, paired with panels, for power without a permanent install.
Mounting and connectors
- Z-brackets for fixed mounts; tilt mounts for more winter sun
- No-drill adhesive mounts avoid roof holes on vans
- Match connectors to your controller or station, and seal any penetrations
Mounts & connectors matter
How a panel attaches and plugs in is where setups fail. Get the right brackets and the right adapters before you hit the road.
Size it right (and a bit bigger)
Because real conditions cut output, size panels to refill your daily use in your worst realistic weather, and lean a little larger. For bigger rigs or full-timers, more panel wattage buys daily headroom.
A 400W off-grid kit
For larger rigs or full-time living, a 400W-class kit gives more daily production to ride out cloudy stretches.
Bottom line
Start from your daily watt-hours, pick a kit or all-in-one that refills it with margin, and don’t skimp on mounting and connectors — that’s where road setups usually fail.
RV & van solar FAQ
It depends on your daily watt-hours, but many setups start around 200–400W of panels with a LiFePO4 battery. Heavier fridge and device use pushes that higher.
Often not. Many RV and off-grid kits supply the panels, controller, and wiring but expect you to add the battery, commonly a 12V LiFePO4 pack. All-in-one solar generators do include the battery.
Portable and all-in-one systems are plug-and-play. Roof kits involve mounting panels and running wiring; if you’re tying into a vehicle’s electrical system and aren’t confident, consider professional help.
Most van setups run on 12V DC with an inverter to power AC devices when needed. Sizing the inverter to your largest AC load matters as much as the battery.
