What Are Solar Panels?

Solar panels show how advanced today’s tech is – using a source of renewable, almost infinite energy to power everyday devices. The great thing about it is that you are completely capable of buying and installing a solar panel on your own nowadays.

Solar panels can be a great source of auxiliary power when you’re supposed to charge your phone, laptop, camera, etc. And they’re usually not expensive.

If you’re RV living, then you’re trying to save every buck. Therefore, why should you use your RVs electricity when you have devices that will transform sunlight into electricity – for free! There are even portable solar panels available to take off grid.

This is exactly what we’ll be taking a look at in this article: what solar panels are best, how to choose the right solar panel for you, and then we’ll list the best flexible solar panels for RVs. Let’s get started.

Three Advantages of Using Solar Panels

Firstly, let’s talk about what makes a solar panel good. It’s three things: efficiency, size, and placement.

Let us talk about placement first as you are the only one who can decide where to place your panel, so it’s fully accessible to the Sun. That’s it, not much about it. The better the placement, the more power it will collect.

Efficiency is the deciding player that separates the really good solar panels from the average or the bad ones. Efficiency defines how much sunlight does a panel need to create a certain amount of electricity.

If you take two panels and expose them to the same amount of sunlight for the same amount of time, the more efficient panel will be the one that’s produced more electricity. You should also know about panels’ overall efficiency because they can’t collect 100% of the sunlight that they face.

They can usually only absorb about a quarter of that energy, with the best solar panels absorbing 23% or more. Lower quality solar panels absorb about 20%.

Last but not least is the size. This is pretty simple to understand – the greater the size of the area exposed to the Sun, the more electricity it will produce.

How Are Flexible Solar Panels For RVs Made?

Solar panels are usually created from one of three materials. Monocrystalline, polycrystalline, or amorphous silicon.

If you are looking for classic solar panels, you must opt for Monocrystalline and polycrystalline. With monocrystalline being much better and much more efficient (and also much more expensive).

Amorphous silicon is less efficient than monocrystalline, but it’s very flexible, portable, and sustainable. However, due to its efficiency, it’s also cheaper than monocrystalline panels.

How To Choose Flexible Solar Panels For RVs?

It’s important to gauge how much power you will need properly. You don’t want to buy a solar panel that’s not producing enough power for your needs. Moreover, you do not want to do the opposite and buy a panel that produces power in excess, which means that you’ve poured money down the drain.

You can find the wattage of the solar panel in the product’s description.

These panels are great because they’re giving you the flexibility and freedom to move around wherever you’d like. Moreover you’re not completely dependent on the electric network.

Now, let’s take a look at some of the best flexible solar panels for RVs.
