Monocrystalline Vs Amorphous Solar Panels

Monocrystalline vs amorphous solar panels. There are three different sorts of solar cell technology available on the market when it comes to solar panel manufacturing: amorphous, monocrystalline, and polycrystalline solar panels.

We will go over all the differences between mono, poly, and amorphous panels in this section. Here, we will give you a little background on each option so you can make an informed decision about which one is best for your situation.

Polycrystalline Solar Panels

Polycrystalline cells are prevalent in rigid panels. They have a lower efficiency than monocrystalline solar cells and need a greater surface area to generate the same amount of power.

These monocrystalline cells are also available in both semi-flexible and rigid form factors. They are more efficient than polycrystalline cells and generate the same amount of power, but they have a smaller surface area. They can also be lighter and more portable than polycrystalline panels in their semi-flexible form factor, according to some sources. If you do not need to transport them on your back, these are the most “cost-effective” options by far.

To be effective, polycrystalline and monocrystalline must be aimed almost directly at the sun. Partial shading or shadows from clouds, trees, leaves, etc. affects both polycrystalline and monocrystalline. They also lose efficiency as the temperature rises in the summer. One thing they are good at (depending on your perspective), is “saving money,” to an extent. The buy-in price is frequently quite low. These are typically the bridge before moving on to semi-flexible monocrystalline in a semi-flexible form factor, which is often lighter than polycrystalline panels and less costly than amorphous panels.


Before I get panels of amorphous, let me tell you how irritated I become when I see videos slating amorphous solar panels for being so expensive. I understand that they are more costly than polycrystalline or monocrystalline cells. However, if the panel is not able to charge my batteries in the field, it is of no use to me. In the event of cloud cover, they are not really a good deal (for me) if I have to repeatedly aim the panels at the sun. Move them out of the trees’ and leaves’ shadows, or handle not having them generate any power because it is cloudy.

Of course, we would have the benefit of fewer trees and more sunshine if I were still living in sunny Southern California or Western Sahara. That is a different story, though. In the real world, we have clouds, trees, and other things to worry about. Our camping sites are usually near sources of freshwater (under trees), and I am frequently on foot when traveling. Am I really going to try to save money by carrying 25-30 extra pounds of mono- or polycrystalline gear? Only if I am on foot or have a restricted wake budget.


Some people would claim that amorphous panels are the most energy-efficient solar technology available to the general public today. Yes, they need twice as much ground area to generate the same amount of power. But they do so in a wider range of weather conditions and at a tenth of the weight. When it is cloudy or overcast, it will produce energy. They will keep generating power when they are partially hidden by trees and leaves.

They are also adaptable! Not semi-flexible, semi-rigid, or any other of those ridiculous marketing phrases designed to deceive you into buying fakes. Amorphous solar panels are also lighter and more transportable than monocrystalline or polycrystalline panels. Despite the fact that they generate the same amount of power. They can also withstand summer heat, unlike mono or polycrystalline panels, which suffer inefficiency when exposed to similar temperatures.

Finally, amorphous panels reflect a wider range of visible light than mono or polycrystalline ones, giving them an edge in brighter settings. In low-light situations, amorphous cells outperform mono and polycrystalline cells. This translates into charging batteries much sooner and keeping them charged later in the day for the mobile user. As opposed to those using mono or polycrystalline panels. Their cost is their main disadvantage.

Amorphous VS Crystalline

Amorphous is made from a thin silicon material that is light, flexible, and able to withstand higher temperatures than poly or monocrystalline cells. It is used for cost-effective applications where flexibility is required (on grouping its non-crystalline form, the term amorphous means without shape).

Crystalline is the most common kind of semiconductor utilized in microchips and photovoltaic solar cell technology. It is typically utilized in power generation and harvesting devices where greater efficiency is needed.


Amorphous solar cells have an efficiency of roughly 7 percent.

Around 15% to 30%, the efficiency of crystalline solar panels is considerably higher.


Amorphous silicon material has a greater tolerance for flaws than crystalline. So it outlasts crystals by a significant amount when flaws are not severely detrimental to overall power output.

Crystalline, on the other hand, is far more brittle and will shatter if one of its components fractures.


The lightest solar panel technology on the market today is amorphous. When compared to others, it is paper-thin.

Shade Tolerance

Amorphous panels work best under low light or bad lighting, so they are better suited for places with little or no sunshine. In comparison to even the most efficient monocrystalline panels, they perform much better in less than ideal sunshine situations. 

Because of their uni-solar triple-junction cell technology. Some special variations of the amorphous material can use indoor light sources for power since they can absorb a wider band of the visible light spectrum.

Portability And Flexibility

Amorphous is the preferred flexible solar panel type for RV or boats. Typically not seen in residential applications.

Crystalline is more durable for heavy-duty applications such as rooftop solar panels for houses, RVs, and hotels (What you see on the roofs of buildings is crystalline).


At a small scale, amorphous (thin film) is less costly to produce and has the potential for cost savings at a large scale ($0.5 – $1.00 per watt, goal – keep under $0.7 per watt at peak performance).
