Solar panels can either be flexible or rigid. Which one you choose will depend on the size and the type of your system on your RV.

When choosing an RV solar system, it is best to start planning with identifying what kind of RV you have. This is because each type of recreational vehicle has specific requirements and limitations for off-grid power and solar charging systems.

Common questions regarding solar and inverter systems in RVs

  • What type of panels to use? Flexible or Rigid
  • How many solar panels do I need?
  • What kind of batteries? AGM, Deep Cycle Flooded, Gel, Lithium
  • What kind of solar controller? PWM or MPPT
  • What kind of solar cells on the panels? Monocrystalline, Polycrystalline or CIGS
  • How do I calculate a reliable power generation system?
  • Running an air conditioner on a solar system and power inverter.
  • Lithium battery bank charging on solar and alternator.
  • How to calculate wattage on common electrical appliances?
  • Any tips on reducing power usage?
  • Can I run a CPAP off-grid while camping?
  • Can I run a refrigerator on a solar system?
  • My RV has a residential french door refrigerator, how can I power off-grid?
  • My RV is prewired for solar, but I cannot find the cables.
  • How to mount the panels to the roof?
  • What kind of sealant is used for mounting RV solar panels?
  • Should I buy an RV portable solar panel?
  • Can I make my own portable solar kit?
  • What kind of solar connectors are out there?
  • Do I need a transfer switch with a solar system?
  • Can I run my lights without an inverter?
  • Can I use my onboard USB connectors when I am not plugged into shore power?
  • I have a 30 amp charge controller and a 50 amp RV, what does this mean?
  • Do I need to tie down or tie-wrap my cables on my roof?
  • Can I mount a solar panel on my roof rack?

Basic components of a solar battery charging system for an RV

Fuse for rv solar wire

Solar fuses

Fuses for the solar system protect the wire from in case there is a short. The fuse is a safety precaution.

Front of power inverter being turned on in an RV

Power Inverter

Power inverters are devices that allow a user to run 120-volt appliances from their 12-volt battery banks. These units come in a variety of models including power waveform of True Sine Wave and Modified Sine Wave and charging models including inverter only or inverter chargers.

Solar panels

Solar panels take light energy from the sun and turn it into useful DC electricity. This electricity is useful for charging batteries or for immediate consumption using a power inverter.

Solar cable entry plate

A prewired cable entry plate on an RV is a simple way to have your RV solar-ready without the need to run additional wires into the RV. The main 10AWG cable run uses a quick-connect MC4 connector base for both the + (Red) and – (Black) cables.

Solar extension cables

Solar extension cables are designed to extend the solar circuit some length. These cables allow for additional panels to be installed some distance from the first panel.

RV Batteries

Batteries are the lifeblood of an RV off-grid power system because they store the power needed at times when there is no power plug. RV batteries are available in a variety of types and common voltages like 6 Volt and 12 Volt.
Learn More

Circuit breakers

Circuit breakers are designed to protect AC wiring in your RV. The breakers are allowed to trip and be reset. They can allow for easily shutting of a circuit.
Learn More
Inverter install kit

Inverter install kit

To install a power inverter, cables and a fuse should be used. The cable should match the wire size required by the load from the power inverter.
Learn More
Solar panel tilted to capture more power from the sun.

Tilt mount for panels

Tilting a solar panel to better angle towards the sun can produce more power. There are brackets that can help achieve this on an RV.
Learn More
Solar charge controller remote panel

Charge controller remote

A remote for a solar charge controller allows the user to remotely read the output of their solar panels. These are usually installed where they can be seen easily inside the RV.
Learn More
Lap sealant used on RV roof.

Lap sealant

Lap sealant is often used when installing solar on an RV roof. Sealant is designed to there to help prevent water from entering your RV.
