The Best Portable Solar Panels for RV

Heading out into the backcountry for some boondocking or off-grid camping can be a wonderful way to escape from the hustle and bustle of the big city. You may head into the middle of nowhere, but this doesn’t mean you have to forgo all your comforts like hot water and light!

Having electricity is a nice luxury to have and the easiest, most environmentally friendly way to do this is with portable solar panels for RVs. If you plan on camping with a few people and have a large RV, you can install a massive solar array with multiple solar panels on the roof of your rig.

If you plan on camping alone and only need a minimal amount of energy for the basics such as light and recharging devices, then smaller portable solar panels are your best bet.

What is a Portable RV Solar Panel?

A portable RV solar panel is a lightweight silicon panel attached to a charge controller that stores and generates electricity. Like the solar panels that are installed on the roofs of houses or large RVs, these smaller portable solar panels are movable and can be placed anywhere around the campsite.

Portable RV solar panels usually have MC4 connectors which allow them to be very easily connected to a charge controller. This charge controller is then connected to the RV’s 12V battery bank or house battery to maintain a constant charge.

Types of Portable Solar Panels for RVs: Polycrystalline vs. Monocrystalline Solar Panels

There are three types of portable solar panels for RVs: Monocrystalline, polycrystalline, and amorphous panels.

Monocrystalline

Constructed from a single large silicon crystal, monocrystalline panels are generally dark blue or black in color and are small making them super-space efficient. They are also very efficient at generating energy/power and least sensitive to high temperatures, however, are more expensive than polycrystalline panels.

Polycrystalline

These panels are created from multiple blocks of silicon and tend to be more affordable than monocrystalline panels as they are less costly to produce. Lighter blue in color, these types of panels, however, are slightly less efficient than monocrystalline solar panels, producing less power and taking up more space.

Amorphous

These panels are created by spreading silicon on a large bed. Also known as thin-film panels, these types of panels are budget-friendly, flexible, and allow for more installation options. The downside to amorphous panels is that they are larger than monocrystalline and polycrystalline panels and need more space to store and set up.

What are the Advantages and Disadvantages of Portable Solar Panels for RVs?

There are several advantages and disadvantages to using portable solar panels for RVs.

ADVANTAGES DISADVANTAGES
No installation is required – they simply need to be placed in the sun and connected. Expensive
Portability – the panels can be easily moved to follow the sun. Large solar panels can be heavy
Direct charge – some portable solar panels for RVs have built-in USB ports that allow you to charge devices directly from the panel itself Require set-up and break-down at each campsite
Can easily be connected to a solar generator small inverter for a compact power station Need to be stored when not in use
Can charge several appliances and devices – laptop computers, small gaming devices, lights, a television, a CPAP machine, and/or a small 12V refrigerator Possibility of theft

Frequently Asked Questions

Who are portable solar panels best for?

Portable solar panels are best used by campers who are planning on going off-grid or boondocking where they will need access to power. They are best for weekenders or basic campers that only need to charge something for a short amount of time.

What size portable solar panel do I need to charge my RV battery?

This will depend entirely on how much power you use and the size of your battery bank. You will also need to take into consideration the variable of the sun itself and its unpredictability – remember the strength of the sun will determine the time it takes to recharge a battery. Other factors such as ambient temperature, the time of day, the location you are in, and the amount of cloud cover play a role in the amount of solar power your panels will produce.

However, there’s a rule of thumb that experts use which says that in general, a 100-watt solar panel will generate around 30 amp-hours per day. Therefore, on average, your 100-watt solar panel will put around 30 amp-hours per day back into your battery bank.

How fast can a 100-watt solar panel recharge a battery bank?

Again, this will depend on several variables including the nature of your electrical system/battery bank, the devices you’re running, how long you run them, how much sun the panels get, as well as several other variables.

If you have a 100-watt portable solar panel, your battery bank will likely be charged sufficiently to power small, low-power-draw devices such as your cell phones, RV lights, vent fan, tablets, small battery packs, and even your water pump – for variable amounts of time.

What will a 200-watt solar panel run?

A 200-watt solar panel will charge your battery bank sufficiently to run small, low-power-draw devices such as your cell phones, RV lights, vent fan, tablets, and small battery packs, as well as small appliances such as a coffee maker and a hairdryer if you have an inverter (though not for extended periods).

Happy Camping!
