Metro Manila, Philippines - The choice of solar panels holds significant weight in determining the longevity and cost-effectiveness of the entire solar energy system. Choosing high-quality panels from a reputable manufacturer can ensure decades of reliable performance, leading to substantial savings on electricity costs over time.

On the flip side, panels from manufacturers prioritizing upfront costs over long-term efficiency may result in a system that underperforms and struggles to withstand the test of time. Selecting the right solar panels is a crucial step in establishing a durable and financially rewarding solar setup.

At PHILERGY German Solar, we are constantly showcasing the highest quality components for the solar systems we offer. But what are these highest quality components? To start off the series, we are going to tell you about the most recognized part of a solar energy system: the solar panels.


Monocrystalline vs. Polycrystalline Solar Panels

Monocrystalline and polycrystalline solar panels are the two most common types of solar panels. Like all solar panels, they capture sunlight and convert it into electricity. Both types use silicon, a material that’s abundant and durable. 

The most significant difference between the two panels is the silicon crystal technology used. Monocrystalline (mono) panels use a single silicon crystal, while polycrystalline (poly) panels use multiple crystals melted together. Here’s a breakdown of more differences between the panels.


Monocrystalline panels feature a singular silicon crystal grown in a laboratory, shaped into cylindrical ingots. These ingots are then sliced into thin discs, known as silicon wafers, which are further crafted into octagonal forms. This meticulous process optimizes space utilization in the solar panel, reducing wasted space between cells. Despite the higher manufacturing costs and the inability to repurpose shaved pieces for other mono cells, the use of a single crystal enhances the efficiency of monocrystalline panels.


On the other hand, polycrystalline solar panels also rely on silicon cells but follow a distinct manufacturing approach. Unlike monocrystalline panels with single silicon cells, polycrystalline panels integrate multiple silicon fragments melted together. The resulting polycrystalline solar cells take on a cube shape and are subsequently sliced into thin wafers. The multi-crystalline production method minimizes wasted space while allowing for the reuse of leftover materials, reducing overall waste.
