Best Solar Battery Charger for RV

When it comes to powering our devices and appliances, it’s easy not to think about how convenient it is when everything is running smoothly. However, you certainly see how easy it is to take for granted when you lose access to that convenience.

This could be due to power outages or when you’re on a trip in your RV, to name a few scenarios. Having a self-sufficient way to achieve electricity generation can be a huge benefit, and solar power is one of the best ways to do this.

If you’re looking for a solar battery charger for your RV or any other purpose, then you’re in the right place. This review will cover some of the best battery chargers for your RV or general use. By the end, you will hopefully have a few options to consider to get you started on your journey to energy self-sufficiency.

Key Takeaways

  • There are three different kinds of solar panels, amorphous, polycrystalline, and monocrystalline.
  • Amorphous panels are cheaper to make but are less efficient.
  • Polycrystalline panels are cheaper but generally not as efficient.
  • Monocrystalline panels are the most efficient but are generally more expensive.
  • Solar battery chargers are great for RVs, as you will typically be out in the wilderness without access to outlets.
  • We will go over a list of some of the best solar chargers for RVs.

How to Choose the Best Solar Panels for RV Batteries

Kinds of Portable Solar Panels

When it comes to solar panels, there are 3 main variants that you will generally consider. These consist of:

  • Amorphous
  • Polycrystalline
  • Monocrystalline

We will go into more detail on each one shortly while comparing their benefits and downsides.


The efficiency of a panel is one of the most important aspects. This refers to how quickly and effectively the panels convert sunlight to energy, and it tends to be one of the main points of difference between the different variants.

Wattage Cells

The cells of the solar panels are what will convert the sunlight to energy, and some may be more efficient because of the design and materials used to make them.

Weight and Portability

If you’re taking your battery and solar panels out with you on your RV or on trips, then the size and weight will be something to consider. If the system is a heavy, bulky setup that takes up a ton of space then it becomes a lot less practical for transportation.

Why Solar Battery Chargers are Great for Off-Grid RV-ing.

When you travel in an RV, often the goal is to get away from it all and have a break from modern life. However, this doesn’t negate the need for the electrical devices that we rely on. Mobile phones are not just a luxury anymore, and people rely on them for work and connection with friends and family.

Plus, we have other modern conveniences that rely on power, and a solar battery means that you will be able to produce your own power when there isn’t an outlet in sight. If they’re portable, then it’s also perfect to take on the road with you as you travel.

Benefits of Solar Battery Chargers

Solar battery chargers have many different benefits, and they can come in handy in a huge range of situations. For starters, they’re perfect for RV travel, camping, or other outdoor activities where acquiring power becomes tricky.

They can also be great if you have unexpected power outages or issues, something that is becoming more and more common even in the most developed countries. As long as you have decent sunlight where you live, a solar battery charger provides you with seemingly unlimited power which means you’re relying on no one but yourself.

Amorphous vs Polycrystalline vs Monocrystalline: What to Consider

As we touched on earlier, there are three major kinds of solar panels. These are amorphous, polycrystalline, and monocrystalline. The differences between these panels can get quite complicated and involved, but we will simplify it here.

Basically, it comes down to energy efficiency, cost, and convenience.

Amorphous panels are quite common, and these are some of the cheapest to buy and manufacture, and they’re easy to use as well. However, they tend to be less efficient than other kinds.

Polycrystalline panels are also somewhat inexpensive, relatively speaking, and they’re also easy to use with decent efficiency. They’re also durable and good for persistent use.

Monocrystalline panels offer the best efficiency, but this does come at a high price when it comes to manufacture, maintenance, and purchasing.

This is a brief overview, and each does have its benefits and weaknesses, so it can be up to you to decide what you prioritize most.
