What is the difference between monocrystalline and polycrystalline solar panels?

We want to introduce you to two popular types of Solar panel technologies that dominate 80% of the photovoltaic market: monocrystalline and polycrystalline solar panels.

But what are the differences between them, you may ask? While both are reliable and have a mature market, they differ in shape and performance.

Monocrystalline and Polycrystalline solar panels

Monocrystalline Silicon Solar Panels

Monocrystalline and Polycrystalline solar panels

Monocrystalline, also called single crystalline silicon solar panels, are easily recognizable due to their external dark black color.

They are made from cylindrical silicon ingots that are cut into wafers and have higher efficiency; thanks to the purity of the silicon, they can better exploit the sun irradiation.

Advantages

Disadvantages

  • High-efficiency
  • Smaller installation area needed in comparison with other types.
  • Long life-span (25-year warranty)
  • Good performance under low irradiation conditions.
  • They are the most expensive solar panels.
  • Circuit breakdown when the solar panel is covered with dirt, shade or snow.
  • Lower performance while increasing the operating temperature.
  • Silicon waste during the manufacturing process.

Polycrystalline Silicon Solar Panels

Monocrystalline and Polycrystalline solar panels

Polycrystalline are also known as multi-crystalline solar panels and, unlike monocrystalline solar panels, the melted silicon to produce them is poured into a square mould.

This silicon is then cooled and finally sliced into square wafers creating the polycrystalline shape.

Advantages

Disadvantages

  • The manufacturing process is simpler and cheaper.
  • There is no silicon waste.
  • They have a higher performance while increasing the operating temperature.
  • Lower efficiency due to low silicon purity.
  • Require higher installation area than monocrystalline solar panel.
  • Lower architecture integration.

The identification of the difference between the Monocrystalline and Polycrystalline solar panels is important when taking the right decision in the early stages of project management especially in huge projects that need an accurate feasibility analysis.

It is important to identify your project specifications accordingly and choose the suitable solar panel that will satisfy your needs with an economic efficiency.

It is always a bonus to select a good brand.
But how can you identify a good brand? Choose a company that invests in their R&D and effectively operate their production process and constantly increases the product quality and fits the market needs. A high reputation and reliability is also a great advantage. They must have long-term warranties to replace the panels in case the performance becomes lower than the standard set.

Amerisolar is the perfect choice. thanks to:

  • Strong R&D department
  • 12 years of product warranty on solar panels.
  • 30 years of warranty on the solar panels performance
  • 3 EL test on each solar panel
  • Chubb insurance on the solar panels
  • More than 1 GWp production capacity
