what will a 100 watt solar panel run

Before installing a compact solar system for convenience and energy-saving, it’s essential to ask, “What Will a 100 Watt Solar Panel Run?”

In general, when laying out a solar power system, it’s necessary to figure out what you intend to power. This way, you could determine the size of the solar panels you require.

A 100-watt solar panel can operate several different devices or home appliances such as lights, fans, and laptops. It is often seen as the type of solar panel with the right size.

But, what can a 100-watt solar panel produce? We’ll cover that topic in the rest of this post!

What Will a 100 Watt Solar Panel Run

A 100W solar panel that acquires 8 hours of sun exposure each day will generate nearly 1 kWh per day. That means a 100 watts solar panel output can reach 365 kWh per year.

If you’re going to look into different scenarios, there are plenty of home devices and appliances that could operate efficiently using 100W solar panels. A single 100W solar panel is capable of running several small devices such as ceiling fans, mobile phones, Wi-Fi or router, lamps, etc.

On the other hand, home devices or appliances like air conditioners, televisions, heaters, etc., will need more than one 100-watt solar panel. To acquire a precise computation of what you can and cannot run with one 100-watt solar panel, you need to analyze the output per day or month.

For instance: compare 1 kilowatt per hour for the solar panel with the requirements of a home appliance. Let’s say a fridge requires 3.8 kilowatts per hour, so this shows that a 100W solar panel will not be adequate to run the fridge.

Meanwhile, a laptop uses roughly 60 watts per hour; hence, a 100W solar panel will be appropriate to satisfy those requirements.

So, what can 100 watts power? To get further details, it is also helpful to check the following list of devices with their wattage:

  • Toaster Oven 1200 watts
  • Coffee Machine 1000 watts
  • Refrigerator 400 watts
  • Drill (1/4 inch) 250 watts
  • TV – LCD 150 watts
  • LCD Monitor: 100 watts
  • Laptop 25 – 100 watts
  • Sewing Machine 100 watts
  • Cable Box 35 watts
  • Satellite Dish: 30 watts
  • LED Light bulb 10 watts
  • DVD Player 15 watts
  • Ceiling Fan 10 – 50 watts
  • Marine refrigerator: 100 watts
  • Tablet Recharge 8 watts
  • Modem 7 watts
  • SmartPhone Recharge 6 watts
  • CB Radio 5 watts
  • Campervan, RV: 400-600 watts

Heads Up: Please be guided that the power ratings aforementioned might not be accurate for all devices or appliances. So, we strongly suggest that you examine the labels indicated on your home appliances to unveil the precise wattage.

How Long Does It Take to Charge 12-volt Batteries with 100W Solar Panels

A 100W solar panel that utilizes an MPPT charge regulator can charge a fully drained 12V li-ion phosphate battery in:

  • 100 Ah capacity – 20 hours
  • 50 Ah capacity – 10 hours
  • 40 Ah capacity – 8 hours
  • 20 Ah capacity – 4 hours

Note that this is presuming the peak sun hours amounting to 1,000 w/m2/h.

What are the Factors That Could Affect the Energy Produced by a 100W Solar Panel

The amount of energy that a 100-watt solar panel generates primarily relies on the amount of sunlight it captures. The maximum energy is 100 watts.

Keep in mind that obtaining this calls for proper installation and is positioned in a suitable direction and angle. Meanwhile, the delightful news is that you could obtain the total capacity in maximum sunlight conditions.

Can You Charge as Many Batteries as You Want with a 100-watt Solar Panel

Luckily, a 100W solar panel allows you to charge several batteries. Fundamentally, the only difference here is the length of time it takes to charge the batteries. Take in mind that you can fully charge a completely drained 12V 50 Ah LiFeP04 battery in ten hours with a 100w solar panel.

Nevertheless, if you intend to charge a bigger battery, it will take an extended period. Indeed, the number of hours increases or decreases hinging on the battery size in Ah (amp hours).

Is It Possible to Link Several 100W Solar Panels

Fortunately, you won’t have severe struggles linking several 100W solar panels to obtain a higher output. Let’s say you have merely a single 100W solar panel, and the output is not enough to meet your energy requirements. To solve this problem, you can effortlessly add more panels.

Moreover, connecting two 100W solar panels supplies you with 200W, while consolidating three panels of this rating supplies you with 300W.

Can Linking 100W Solar Panels in Parallel or Series Increase Watts

Once you link two 100W solar panels in series, the voltage increases and the current remains the same. On the other hand, when you link the two 100 W solar panels in parallel, the current increases, and the voltage remains the same.

Batteries and 100W Solar Panels

Considering the compatibility of batteries and 100-watt solar panels is critical. As you might already know, 100W solar panels are incapable of storing energy, which conveys that storing solar energy in the battery will enable you to consume it at dusk.

The distinct forms of batteries that are designed to accumulate solar energy are lithium-ion and lead-acid batteries. Note that the latter calls for a higher capacity, which is nearly double to accumulate solar energy. Meanwhile, the former merely necessitates a little more capacity.

The Perks of Using 100-watt Solar Panels

100-watt solar panels come with a measurement of roughly 47 x 21.3 x 1.4 inches. So, this implies that they are the ideal size to carry around. As for the sizing, the size of the solar panels depends on their efficiency and design.

If it is your first time installing solar systems, you can begin with a 100w solar panel kit. It generally includes the items necessary to complete the installation process. Furthermore, if you wish to add more in the future, all you need is to purchase the solar panel.

Newbies in using solar energy will find 100-watt solar panels convenient and user-friendly. Likewise, they can be a DIY project to work on if you’re willing to do the task on your own.

100-Watt Solar Panel Output During Overcast Days

The solar panel’s efficiency mainly counts on the sun exposure permeating the cloud and reaching the solar panel. It is essential to know that there’s typically a decrease in solar panel efficiency between gloomy days and sunny days of up to sixty-five percent. Note that this usually hinges on the cloud cover and quality of the solar panel.

Final Thoughts

Hopefully, our article gave you a detailed answer to the question, “what will a 100 watt solar panel run?” Such a compact solar panel allows us to install on our RVs and utilize it with ease.

Also, here’re a few things to take note of before purchasing one for your home, workplace, or outdoor adventures.

If you go for a 100-watt solar panel:
