11 Best 100 Watt Solar Panels Under $200 You Should Buy

“I’d put my money on the Sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run before we tackle that.”

– Thomas Edison, 1931


There’s enough solar energy hitting the Earth every hour to meet all of humanity’s power needs for an entire year. (Source)

As rightly said 88 years back by Sir Thomas Edison, it is an excellent source of energy.

I hope you all agree with it!!

If not, don’t worry, I have got your back.

At the end of this article, you will be left with no doubts.

Let’s not go into the detailed definition of solar energy. I’ll explain to you in the simplest way possible.

Solar means relating to or determined by the Sun, and solar energy is radiant light and heat from the Sun.

To utilize this energy, we require some technology, and we humans have created solar panels to use that energy in completing all our power needs.

Buying a solar panel is a grinding task, moreover, choosing from the stack of best is more puzzling, as there are a lot of options to choose from in today’s world.

To make your life easier and save your time, I’ll be helping you in selecting the Best 100 Watts Solar Panel.

By the end of this article, you will be completely aware of:

  • What is Solar Energy?
  • What are Solar Panels?
  • Types of Solar Panels?
  • Best 100 Watts Solar Panel
  • Which one is the best for you to buy right now?

Let’s get started.

What is Solar Energy?

“Use of solar energy is near a solution”.

– This was the headline in the New York Times on 4 April 1931

According to Wikipedia, solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaic, indirectly using concentrated solar power, or a combination. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.

As explained above solar energy is produced by the Sun’s light. Photovoltaic is a method for generating electric power from sunlight.

It has a lot of benefits when compared to all the other forms of energy. It is:

  • Renewable
  • Inexhaustible
  • Non-polluting
  • Avoids global warming
  • Reduces the use of fossil fuels
  • Reduces energy imports
  • Generates local wealth and jobs
  • Contributes to sustainable development
  • Modular and very versatile, adaptable to different situations
  • Can be applied alike for large-scale electricity generation and on a small scale in areas isolated from the network

Since it comes from the sun, solar energy is harnessed using mirrors and panels. Here’s when solar panels come into the picture. Let’s have a conversation about them now.

What are Solar panels?

According to Wikipedia, photovoltaic solar panels absorb sunlight as a source of energy to generate direct current electricity. A photovoltaic module is a packaged, connected assembly of photovoltaic solar cells available in different voltages and wattages.

These panels produce direct current electricity from sunlight because of solar cells which can be used to power equipment or to recharge a battery.

There are two main types of solar panels in the market. Let’s discuss them in brief.

Check out our detailed guide on How Do Solar Panels Work

Types of Solar Panels

If you are looking to get a solar panel from Amazon then you will mainly come across two types, which are monocrystalline and polycrystalline.

Both the types have their own advantages and disadvantages and when it comes to selecting the type best suited for you, then it solely depends on your purpose and needs.


Made with high purity silicon, these type of panels have a uniform dark look with round edges. Due to pure silicon, these panels have higher efficiency rates with high output. 

They also take less space and can last for quite a while. The catch here is that these panels are expensive when compared to polycrystalline solar panels.


These panels are made by melting silicon fragments which result in cheaper but lower efficiency solar cells. The polycrystalline panels give a more blue-ish shade and are divided into small squares. Their efficiency and life span is not great but is easily affordable.

However, when it comes to real-world tests and power output the differences are not so significant.
