PERC Solar Panels – Top Benefits to Know

In a conventional solar panel, some of the sunlight gets reflected off the surface, blocked by the metal grid lines, or passes through the cell without generating electricity, instead producing heat. This leads to energy loss and reduced efficiency. To address these issues, a front passivation layer is added, which helps reduce reflection and recombination on the front side of the cell, improving overall performance.

By effectively managing these inefficiencies, PERC solar panels offer a more efficient solution for energy generation.

What Are PERC Solar Panels?

Passivated Emitter and Rear Contact (PERC) panels are built using PERC cells, which are designed to be more efficient than traditional solar cells. The key difference lies in the additional layer on the back of the cell, which allows more light to be absorbed and converted into electricity. This layer also helps prevent rear-side recombination, reducing heat loss and improving performance, especially with longer wavelengths of light.

Although PERC technology was first developed in 1989, it has seen significant improvements over the years, making it a strong competitor to traditional solar panels. Importantly, PERC panels can often be produced using existing manufacturing equipment, which makes the transition from traditional to PERC more cost-effective.

Different Types of PERC Solar Modules

There are two main types of PERC solar panels, each offering different levels of efficiency and cost.

Mono PERC Solar Panels

Mono PERC panels, or monocrystalline PERC cells, are made from a single crystal of silicon. These cells are known for their higher efficiency compared to polycrystalline panels. They are also more expensive due to the purity of the material used. Adding multiple PERC layers can further enhance their efficiency, making them ideal for space-constrained installations.

Poly PERC Cells

Polycrystalline PERC cells are made from fragments of silicon, which gives them a lower efficiency than monocrystalline versions. However, they are more affordable and still benefit from the addition of a PERC layer, which can boost their performance. While not as efficient as mono PERC, they remain a practical choice for budget-conscious consumers.

Benefits of PERC Solar Panels

Increased Energy Production

Compared to traditional solar panels, PERC cells can produce about 1% more energy. Although this might seem small, it adds up significantly when considering an entire photovoltaic system. In fact, a system using PERC panels can generate up to 5% more power than one using standard panels.

Improved Performance in Low-light and High-heat Conditions

Traditional solar panels tend to struggle in low-light or high-temperature environments, but PERC panels perform better under such conditions. They can even see a 3% increase in efficiency when exposed to high heat and limited sunlight, making them a reliable choice for diverse climates.

Smaller Roof Footprint

Owing to their increased efficiency, PERC panels require fewer units to meet the same energy needs. This means less space is needed on the roof, making them ideal for homes and businesses with limited installation area. For example, if a system requires 40 standard panels, it may only need 38 PERC panels to achieve the same output.

Reduced BOS and Soft Costs

Since fewer panels are needed, PERC technology helps cut down on balance of system (BOS) costs, including inverters, wiring, and labor. This makes the overall installation more cost-effective for both homeowners and installers.

Same Manufacturing Costs

One of the major advantages of PERC panels is that their manufacturing cost is comparable to that of traditional panels. This means that the price per panel remains competitive, making PERC a smart upgrade without a significant price hike.

In conclusion, PERC solar panels are an excellent option for those looking to maximize energy output while minimizing installation costs and space requirements. With improved efficiency, better performance in challenging conditions, and similar pricing to traditional panels, they are becoming a popular choice in the solar industry.
