How We Chose The Best 100 Watt Solar Panel Kits

In our search for the best 100W solar panel kits, we found many great options. We found so many in fact, that it was hard to choose which ones to feature. We ended up basing our decision on a few simple factors including efficiency, durability, versatility, and ease of use.


All 100W solar panels are designed to produce 100W of power under optimum conditions. Unfortunately, optimum conditions are not always available. That is why we looked for high-efficiency panels that could still collect a fair amount of power even when the weather is less than perfect.

Durability and Versatility

Many people choose 100W solar panels because they are smaller and more portable than the larger panels designed for roof-top installation. This portability makes them particularly popular amongst campers, RVers, and van lifers. With this in mind, we sought out 100W kits that were durable and versatile enough to meet the needs of all of our solar loving adventurers.

Ease of Use

There are a number of things about switching to solar that can be complicated, but it doesn’t have to be scary, especially if you start with a small solar kit like those on our list. We chose these kits because they are good for both beginners and solar pros. With easy installation and operation as well as including most of the necessary accessories, these kits offer easy access to solar energy at a price that is much more affordable than a full home system.

What You Need To Know About 100-Watt Solar Kits

If you are new to the solar scene, here is a quick summary of some useful things that you should know before you purchase your first solar kit.

Monocrystalline Vs. PolyCrystalline Vs. Flexible

If you’ve been researching solar power for any amount of time, you probably already know that solar panels come in a few different varieties. The three most common types are monocrystalline, polycrystalline, and flexible, or thin film.

Monocrystalline and Polycrystalline are very similar. They are both made out of silicon crystal wafers. The wafers used in monocrystalline panels are cut from a single lab-created silicon crystal. The wafers for polycrystalline panels are cut from silicon crystals that have been melted down and pressed together to form a large block.

So what does that mean exactly? Basically, monocrystalline panels are slightly more efficient, but they can also be more expensive. When it comes to smaller panels, like the more portable options on our list, monocrystalline is better because it can generate more power per square inch. In terms of large home solar kits, the difference in efficiency is sometimes negligible, but that’s a discussion for another day.

Flexible solar panels are relatively new when compared to monocrystalline or polycrystalline panels. Flexible panels can be made out of a number of different materials which could explain why they vary so much in their levels of efficiency. The technology behind these panels has improved quite a bit over the last few years, but in general, they are not as long-lasting or as efficient as traditional panels.

Charge Controllers

Charge controllers are an extremely important element in any solar system because they regulate the electrical charge going into your battery bank. The amount of energy being generated by your solar panel will fluctuate all throughout the day based on the amount of sunlight. This is not good when it comes to your battery bank because without regulation that fluctuating power can cause overcharging, short-circuiting, and other battery-damaging conditions.

There are two main types of charge controller, PWM and MPPT.

PWM or Pulse Width Modulated, charge controllers are commonly thought of as basic charge controllers. These are the simplest and least expensive of the two options. PWM controllers work by monitoring the battery’s charge and allowing power through to the battery as it is needed. Although these controllers work just fine for small solar arrays, they are not a good choice if you plan on building a large solar system.

MPPT or Maximum Power Point Tracking, controllers work in a similar way, but they are more advanced. These controllers don’t just track the amount of power that your battery needs, they also track things like temperature and voltage. They are designed to electronically track and accommodate changes in voltage as well as charge your batteries as efficiently as possible. MPPT controllers are a good choice for every type of solar system, but they can be quite a bit more expensive than PWM, so if you have a smaller system, it might not be worth the extra money to purchase an MPPT controller.

Expert Tip: Keep in mind that charge controllers come in different sizes and that you have to have a charge controller that is powerful enough to handle the amount of electricity coming out of your solar array. All controllers come with a list of specifications showing what they can handle, but if you’re not sure, ask a professional before making your purchase so you don’t end up buying something you can’t use.

Battery Power

Solar panels generate power but they don’t store it. Because of this, most people choose to combine their solar panel with a solar battery or power station so that they can store up the power and use it later on. When it comes to portable solar panels, most people prefer using power stations because they are also very portable and user-friendly. The best choice for you will depend on your situation, just be sure to choose a power storage option before taking your solar panel on any adventures.

How to Choose The Best 100 Watt Solar Panel Kit For You

Since all of these kits are designed to produce the same amount of power and you now know what to look for in a quality solar panel, the only thing you have to worry about when choosing your kit is the style. There are several styles to choose from and each has its own benefits. The way you plan on using your solar panel will dictate the style you need.

If you’re planning on using your solar panel for camping trips, then you will want to choose a lightweight durable model like the Rockpals Foldable Panel on our list. If you’re looking for a way to add a little free electricity to your RV or camper, then a more permanent option like the TP-Power kit would be a better choice. For those of you who want a multi-purpose solar panel kit to use at home and on the go, our overall pick from Renogy is the one for you.
