In recent years, there has been a surge in the popularity of Passivated Emitter and Rear Contact (PERC) solar panels within the solar industry due to their ability to enhance solar power efficiency. These panels utilize PERC solar cells, an upgraded iteration of traditional solar cells. With their innovative design, they can produce 6 to 12 % more energy compared to their conventional counterparts.

The acronym PERC stands for Passivated Emitter and Rear Cell. The distinctive feature of a PERC solar cell is the presence of a passivation layer on its rear side, which plays a pivotal role in reducing recombination losses and boosting light absorption. Essentially, the rear-side passivation layer acts as a light reflector, preventing sunlight that passes through the silicon cell from escaping without absorption. This reflective capability provides the solar cell with a second opportunity to absorb the light, resulting in a significant enhancement in overall efficiency.

Advantages of PERC Solar Panels

  • Enhanced Energy Production: PERC panels boast higher efficiency, leading to a potential 5% increase in energy production for an entire (PV) stands for Photovoltaic system.
  • Improved Low-Light and High-Heat Performance: PERC panels excel in low-light and high-temperature conditions, delivering approximately 3% higher efficiency.
  • Superior Area Efficiency: Thanks to their increased efficiency, PERC panels can achieve the same power output as traditional panels using fewer units, reducing the installation space required.
  • Lower Balance of System (BOS) Costs: Fewer PERC panels can achieve equivalent output, resulting in reduced BOS costs, labor expenses, and soft costs like inverters and disconnects.


Disadvantages of PERC Solar Panels

  • Higher Cost: PERC solar panels generally come at a higher price point compared to traditional panels.
  • Shading Sensitivity: PERC panels are slightly more susceptible to shading issues than traditional solar panels.
  • New Technology Uncertainty: As a relatively new technology, there may be some uncertainty regarding the long-term durability and performance of PERC solar panels.


Uses of Perc Solar Panels

  • Commercial Buildings: Mono PERC solar panels find application in commercial structures like office buildings, shopping centers, and warehouses, helping cut electricity expenses and lower carbon footprint.
  • Large-Scale Solar Farms: Mono PERC solar panels are deployed in utility-scale solar power plants, contributing to the generation of electricity on a grand scale.
