PERC Solar PV Modules
In recent years, PERC (Passivated Emitter and Rear Contact) solar panels have been gaining popularity in the solar panel industry as a viable option for producing solar energy more efficiently. These solar panels use PERC solar cells, which are an improved version of traditional solar cells. Their modified design allows them to produce 6 to 12 percent more energy than their conventional counterparts.
About PERC Technology
PERC stands for Passivated Emitter and Back Cell. PERC solar cell features the presence of a passivation layer on the back side of the cell, which helps minimize recombination losses and increase light absorption. The main role of the passivation layer on the back side is to reflect the light passing through the silicon cell without absorbing it back into the silicon. The passivation layer reflects this light, giving the solar cell a second chance to absorb it, resulting in a significant improvement in efficiency.
Advantages of PERC Solar Panels
PERC panels offer several advantages over traditional solar panels; This makes them a popular choice for solar installers and customers. Here are the main advantages:
Increased Energy Production: PERC solar panels have higher efficiency compared to traditional panels, resulting in increased energy production. It can provide up to a 5% increase in energy production for a complete PV system.
Increased Low Light and High Temperature Performance: PERC panels perform exceptionally well in low light and high temperature environments, providing increased efficiency of approximately 3%.
High Area Efficiency: Because PERC panels are more efficient, they can achieve the same power output as traditional panels with fewer panels. This means that a solar power system using PERC panels will require less space for installation.
Less BOS Cost: With PERC panels, fewer panels can achieve the same output; This helps reduce system (BOS) costs, labor costs and other costs such as inverters and connectors.
Disadvantages of PERC solar panels
PERC solar panels are generally more expensive than traditional solar panels.
PERC solar panels are slightly more sensitive to shading than traditional solar panels.
PERC solar panels are a relatively new technology; There may be some uncertainty about their long-term durability and performance.
Applications of PERC solar panels
Residential roofs: MonoPERC solar panels are a popular choice for residential roofs due to their high efficiency, which allows homeowners to produce more electricity from a smaller roof area.
Commercial buildings: MonoPERC solar panels can also be used in commercial buildings such as office buildings, shopping malls and warehouses to offset electricity costs and reduce carbon emissions.
Large-scale solar power plants: Mono PERC solar panels can be used to generate grid-scale electricity in large-scale solar power plants.
