Things to Consider

With so many choices it could be daunting picking the best 100-watt solar panel kit for your use. Whether it’s to power devices at home or your ideal solution for your next RV road trip, the information below will make you a more informed buyer.

What can you power with a 100W solar panel?

Top Ten 100-watt Solar Panels of the Highest Quality

You may be wondering what you can use a 100W solar panel for? The 100W rating means that in optimal conditions, there’s an output of 100W DC power. Note that this is only if conditions are pristine, such as it getting full sun throughout the day.

100W solar panels are mostly used to power electronic devices and appliances instead of using a traditional power source. But what you can power isn’t only about the solar panel’s ability, but what exactly you plan to power and the wattage rating of that item.

The average amount of power generated by a 100W panel during the sunny part of a day can power certain lamps for over 30 hours. You can even watch TV but that will only last for around 5 hours.

When powering a computer like a laptop, you’ll have power for anything between two and 10 hours, depending on the laptop you use and what you’re using it for.

You can boil a kettle, charge your mobile device a few times or even power up a camping fridge, although the power won’t last very long for that task.

Features to consider before you buy a portable solar panel

You can see the market has many options of the best portable 100-Watt solar panels and the characteristics listed below will give you a good idea of how to compare them. Read up on the details so you can select that right solar panel for your use.

Type and usage

Firstly, you can look into the type of panels the unit is made of. The three options are:

  • Monocrystalline, which is very efficient and therefore gives a better output
  • Polycrystalline that tends to be a bit cheaper than mono panels
  • Thin-film panels that are more portable and flexible, so they don’t damage as easily


You can see each of these carries its own benefits.

You need to consider what you’ll use the solar panels for. For example, adding a permanent structure to your home to power a pump or some small appliances, simply to reduce your use of the grid requires high efficiency with mono panels. But if you’re going camping the portability of the unit is perhaps more important, so flexible thin film panels would be your go to.

Size and weight

It doesn’t always help to simply get the biggest solar panel on the market, because its efficiency also determines whether it will suit your needs. Also, you need to consider practical aspects such as where you’ll have space to mount it or transport it if you’re taking it on an RV trip. If you need to carry it on your own it must be comfortable to handle, which makes the foldable models such as the Jackery SolarSaga 100W Portable Solar Panel so valuable.

The weight also plays a role in its portability and if you need to carry it around a lot or hoist it up on top of your boat, RV or car’s roof to get the best sun exposure, the lighter the better. Look at the Renogy 100-Watt 12-Volt Extremely Flexible Monocrystalline Solar Panel as an example of how extremely light this equipment can be if you find the right kit.

Connectivity

No solar panel can work in isolation. You need to connect it to other components like inverters, controllers and batteries to store the generated power. A quality kit will make it easy to connect such as providing the necessary cabling and being compatible with a range of batteries, even from other brands. When you’re shopping, look for kits that have quality cabling and high-end components like crocodile clips, so they won’t easily wear out or cause connectivity issues.

As you can see on many of the models we showcased, such as the Rockpals 100W Foldable Solar Panel, kits often come with connection ports to charge devices, thanks to built in USB outputs. Since charging devices like small lights or mobile phones is a popular reason why people invest in solar panels for camping or boating, these features are valuable.

Efficiency

Top Ten 100-watt Solar Panels of the Highest Quality

You’ll see in our reviews that we mention efficiency. This refers to the percentage of the sunlight hitting the panels that actually get transformed into power that you can use. You need a decent efficiency rating or you won’t get a lot of power from your set, or it won’t perform very well if the conditions aren’t perfect. If the efficiency rating is low you’ll probably need more solar panels to get the output you’re after.

A good rating is between 15% and 22%, which makes the Rockpals 100W Foldable Solar Panel with its high rating a valuable item on our list of solar panel reviews.

Warranty

It’s an industry norm to see performance warranties of 25 years on modern solar panels. However, read the fine print because other warranties may apply to other aspects of your equipment. For example, look at the Renogy 100-Watt 12-Volt Extremely Flexible Monocrystalline Solar Panel with its 5-year warranty on workmanship even though the panels themselves may still produce electricity. Other units may only offer 1-year cover, because the controllers, frames or other components may not last as long as the ability to generate power. Make sure of what you’ll be covered for so you can plan purchasing replacements if necessary.

FAQ

Note that each system is unique, so good instructions from the manufacturer are ideal.

In general, you start by looking for the best place to position the panel itself. It must get full sun, without trees or other objects creating shade. Also angle it correctly so the rays fall onto the surface. You may need to move it throughout the day to optimize output.

The panel needs to connect to a controller. This unit helps regulate the flow of power to batteries. From the controller you’ll run cabling to a battery to store the generated power and this is where you’ll draw power for your appliances from.

You also need an inverter, which will change the solar power from DC current to AC current, which you need for most home devices.

Many solar panels are waterproof but you can’t assume that they are. Look for IP ratings—such as IP68—which shows it’s been tested to work even in very windy and rainy conditions. If it’s not waterproof certain components may get damaged by moisture.

If it’s waterproof it’s a huge plus because rain can help keep the surface clear of dust, optimizing output. If it’s also strong enough not to break under heavy snow, it’s a quality buy.

Yes, many solar panels will still generate power during cloudy days and rainy conditions but you can expect the output to be less compared to sunny days. The produced power can drop by up to 75%.

Our Verdict

We strongly suggest you opt for the Renogy 100W monocrystalline solar starter kit if you’re ready to go solar. It helps that you get most of what you need to start your solar setup and the monocrystalline panels are efficient. The backlit LCD screen is a helpful extra and the IP65 rating means you have peace of mind about using it in the rainy season.

You can also not go wrong with the Jackery SolarSage 100W Portable Solar Panel. This comes from a respected brand and the kickstand along with its foldability and carrying handles make it ultra-portable and practical.

One of our best 100-wat solar panel options is also the Rockpals 100W Foldable Solar Panel. With it folding up compactly and having multiple USB outputs, it showcases how practical modern designs can be, ideal for home use or during your next RV excursion.

You can have power wherever you go and there’s a panel for every scenario. Which one will you use?
