Difference Between Poly Solar Panels and Mono Solar Panels

Solar panels are split into two categories depending on their tech: crystal and thin-layer solar panels. Monocrystalline and polycrystalline (mono and poly solar panels) crystal panels are the two types of crystal panels. Although polycrystalline panels perform better with scattered radiation, mono-crystalline photovoltaics have a higher capacity when exposed to full sunlight, these are minor differences.

Apart from this basic difference both poly and mono-crystalline solar photovoltaic panels have a great many differences in their working, appearance, and prices too. This article focuses on highlighting such differences and distinctions amongst the two types of solar panels using descriptive pointers and a comparison table as well.

Poly Solar Panels vs Mono Solar Panels

The main difference between the poly solar panel and mono solar panel is that in poly solar panels each photo-voltaic cell is made up of numerous crystal fragments of silicon during its manufacturing hence they are called “poly” panels whereas in mono panels only a single crystal is embedded in each PV (photovoltaic) cell. This difference causes an immense change in their output performance.

Ply Solar vs Mono Solar Panerls

Mono solar panels are distinguished by their curved edges and black Photovoltaic modules. They create more kilowatt-hours of power than poly panels because they have an increased conversion rate. Monocrystalline or mono solar panels will be more effective per square meter if you really want to build a solar energy system but have limited room. They are the most effective energy panels, but they seem to be the most pricey, due to the more sophisticated production process of pure silicon cells.

Photovoltaic modules in multilayer solar panels aka poly solar panels are blue and have sharp lines. They have a smaller value than monocrystalline silicon cells or mono modules, therefore you’ll need more modules to get the same amount of electricity. Poly solar panels, on the other hand, are less expensive because of their easier production method.

Poly solar panels are extremely sturdy, however, they do not last as long as mono solar panels. Extreme temps also impact them more, reducing their output in the warmest periods.

What is Poly Solar Panel?

When bigger crystals are generated in the early stages of developing crystalline (typically 6 generally aligned), and the panels for a photovoltaic array are cut with such a quartz slab, the cells are referred to as polymorphic or multi-crystalline cells, these are the basic units of making a poly solar panel in the first place.

The heterogeneous cell, which is distinguished by its lighter-colored blue hue, is not monochromatic, with some cells being paler than others. The corners of poly solar panels are not curved. The manufacturing procedure causes color variations in the cells. Inter silicon cells are more cost-effective than single crystal silicon cells.

The liquid silicone is injected into molds that are carved into the slabs during the manufacturing of the poly solar cells. Crystallites emerge during unification, and flaws form at the sharp edges, lowering the effectiveness to 10-14 percent and reducing the projected longevity to 20 to 25 years.

Poly solar panels have lesser performance, but the advantage to buyers is that they are cheaper. Furthermore, while looking for combinatorial solar cells for sale, dealers may emphasize the blue color of these cells as opposed to the black hue of mono solar panels.

What is Mono Solar Panel?

Monocrystal silicon cells or mono solar panels are those in which the whole cell area is made up of only one crystal. Because of the manufacturing method and the structure of single crystalline silicon, a normal mono-crystalline solar panel is dark in color, and the corners of the solar panel are generally curved and rounded up. When solar panels were initially introduced to the market, monocrystalline solar panels were thought to be superior to poly photovoltaic power. This view is based on several factors.

Mono panels are the most efficient, with effectiveness rates ranging from 15-20%. Because of their amazing accuracy, they create more electricity per sq foot and take up less space. In hot temperatures, these solar cells are more efficient. As the temperature is raised, performance drops a little, although not as much as with poly solar panels.

Nevertheless, it is clearly not true that mono solar panels are superior to poly solar panels. Without generalization, each solar array and photovoltaic makers should be evaluated separately. The Czochralski technique or floating area technique are the most common methods for producing mono silicon wafers for the creation of mono and poly solar cells.

Main Differences Between Poly Solar Panels and Mono Solar Panels

  1. Poly solar panels are cheaper than mono solar panels per square foot.
  2. Poly solar panels show less effectiveness in higher peak temperatures than the solo crystalline solar panel.
  3. Poly solar panels are made up of many silicon crystals molded inside them whereas mono solar panels contain one PV cell with one silicon crystal each.
  4. Poly solar panels are used in larger areas whereas mono solar panels are preferred in single module applications like running a mechanism or a unit.
  5. Poly solar panels are durable but not as durable as mono solar panels.


With a cell membrane of 1m2, mono silicon cells can generate 1000 W/m2 of solar energy. From molten silicon crystal chunks, mono-sticks are removed and flat panels are cut. This method of production offers a high level of productivity. And, the poly solar cells can transform 1000 W/m2 of solar light into 130W of electric power. However, with time the poly solar panel’s effectiveness is reduced.

So, both panels have their own unique selling points and are excellent choices. Using them interchangeably, depending on the organization, setup, or module numbers might be a fantastic choice if choosing for a solar system.
