Understanding 100-watt Solar Panel

A 100-watt solar panel is convenient and easy to replace. Similarly, the size is the best for portability. This solar panel is getting popular for home and outdoor solar systems. 

But before we go further, it is important to know that the size of a 100-watt solar panel is smaller than a traditional home solar panel. 

But, they are efficient enough to generate adequate energy from the sun. Also, you can pair a 100-watt solar panel with battery storage to store excess energy and use it when needed.

We discuss the battery in the next paragraph. Now, let’s explore the details of a 100-watt solar panel.


The size of a 100-watt solar panel depends on the design and manufacturer, but the most common measurement is around 47 x 21.3 x 1.4 inches. However, the size may vary, but the solar cells and 100-watt capacity will remain the same for all brands.


The price of a 100-watt solar panel depends on several things, such as brand, efficiency, and location; 100-watt solar panels can vary. 

You have to pay more if you want to purchase other equipment with the solar panel, including module, charger, controller, cables, and brackets. 

In general, you will find a solar panel with 100-watt efficiency from $100 to $400.

How much power does a 100w solar panel produce?

The most important question for solar consumers is how much energy does it produce?

If you want to understand the answer to this basic question, you have to learn several related things supplementary to a solar panel and its production. 

A 100-watt solar panel represents the photovoltaic module that is rated 100 watts. The solar panel can produce 100 watts of DC power under optimal conditions. 

Lots of things are related to the energy production of a solar panel. To find the actual production rate, you have to install the solar panel at the right angle and focus it in the perfect direction. 

Besides, you must have a mounting option that can absorb sunlight all day long.

Batteries need

Battery works as energy storage in the solar system. If you have a battery with a solar panel, you can run the devices at night. 

Remember, solar panels can produce energy from the sun, and the sun is only available during the day.  

However, the battery is not mandatory with a home solar system because you can import and export energy from the grid. 

But, a 100-watt solar panel sometimes produces more energy than your consumption. In this situation, if you have a battery, you can store the energy for further use. 

This method helps your system remain productive even at night. You have to select a solar battery to store energy and keep in mind that lead-acid batteries are not suitable for a solar system. They can’t run below 50 percent.

Another option is a lithium-ion battery. These batteries can discharge completely and store more energy every time.

Companies that produce 100-watt solar panel

Several companies in the energy industry produce solar panels, and it is better to find a company that has specialized manufacturing and design capacity for 100 -watt solar panels.

Here, we present a shortlist of the best companies that produce 100-watt solar panels.

  • Renogy
  • Coleman
  • Newpowa
  • Eco-Worth
  • Richsolar
  • HQST
  • WindyNation
