What Can A 100-Watt Solar Panel Charge?

If you’ve been on the hunt for solar panels lately or have just been considering what solar options you have, chances are you’ve come across a bunch of different panels with different wattages.

The wattage of a solar panel is also called their power rating, and it’s simply a description of the panel’s ability to produce power. On average, the standard solar panels that most people install in their homes have a power rating between 250W-350W, but recently, the 100W panel has been growing in popularity.

What can a 100 watt solar panel charge? Despite the lower power rating, these panels can actually handle a lot of the basic electronic devices we have at home, especially when paired with a good battery. Phones and emergency GPS are perfect items to be charged from a 100 watt solar panel.

In this article, we take a close look at these solar panels, what they can do, the advantages of getting one, along with a quick look at some other low-power solar panels.

What Can A 100 Watt Solar Panel Charge?

On a daily basis, these solar panels can handle a lot of the smaller devices we have at home. However, it should be noted that a couple of things factor in when it comes to the capabilities of a solar panel.

For starters, the type of charge controller being used plays a part in what the panel can power. A charge controller is basically a limiter for the electrical current that is added or drawn to a battery.

These can protect batteries from being overcharged and sustaining damage and loss of power in the long run. Another factor to consider is the actual battery that’s being used by the panel, as this can also affect how much power the panel produces.

But normally, with a standard charge controller and a decent battery, these panels can handle devices such as phones, Lights, laptops, and Portable heaters, and much more.

Figuring out the wattage of your devices can help you a lot in determining if a 100-watt solar panel can charge it. These panels can also easily charge a phone, however, how well and how fast it charges your phone will also depend on the type of battery your phone has and the type of charger you’re using.

If you want to learn more about the wattage of some of the devices and appliances you have at home, you can always do a quick search online or check out an appliance energy calculator such as the one of Energy.gov.

Are These Panels Hard To Setup?

Normally, these panels are designed to be portable. That’s one of the reasons they have grown so much in popularity. Since they’re designed to be moved around, it should come as no surprise that the setup and installation of these panels are relatively easy.

In fact, there are a lot of panels out there that are foldable, so they can be easily stored somewhere to be taken out and used when needed. The key to a proper installation of one of these panels has to be where they are placed.

As they need light from the sun to convert into electrical energy, you have to make sure you put it in a place where they can receive the most sunlight possible. That way, the panel will surely be powered and ready whenever needed.

Do They Work When It’s Cloudy?

This is one of the most common questions asked by people who are just getting into solar panels are have just started considering more sustainable sources of energy.

While it would make sense to assume that these panels won’t work when it’s cloudy, that assumption is very wrong. On a cloudy day, solar panels can still produce 10-25% of their average output.

Now, this is significantly less than when in contact with direct sunlight, but it’s definitely something.

In fact, constantly being exposed to direct sunlight could actually damage the solar panels. When exposed to high temperatures, solar panels tend to degrade, which is why it’s ideal to keep them in places that stay below 77 degrees Fahrenheit or 25 degrees Celsius.

Since these panels produce much less power on cloudy days and a 100-watt solar panel is already on the lower end of the power scale, you can expect a large drop in power on a cloudy day.

But rest assured that these panels are still converting light energy into electrical energy, just at a much lower rate.

Alternative Power on cloudy days

When the sun isn’t shining and you still need power you could consider taking with you a large power bank or power stations as the larger ones are often referred to as.

In simple terms these are large powerful rechargable batteries that can power even large items like TV’s, Lights and Even portable heaters.

What Other Solar Panels Are Out There With Low Power Ratings?

There are a lot of solar panels with a wattage below 100W out there, and they are even more portable than the 100W ones. In fact, there are models that are designed to be strapped to your bag while hiking so that you charge the panels while doing physical activity.

While these panels are more portable and can actually fit in your bag, there is a significant trade-off when it comes to power. These panels are usually somewhere between 20 and 50 watts, which can easily charge your phone, or a camera, or a Bluetooth speaker, but they won’t really power anything much more than that.

But considering the fact that these were designed to be used while outdoors and on the move, the capabilities of these portable solar charging panels are nothing but fitting.
