What is a PERC PV module?

KingsunEstate offers a complete range of PERC PV Modules featuring advanced Passivated Emitter and Rear Cell technology. Our modules deliver higher conversion efficiency, superior low-light performance, and long-term reliability, ideal for residential, commercial, and utility-scale solar projects worldwide.

The back of traditional crystalline silicon solar cells is completely covered by metal electrodes, while PERC cells have been improved in terms of the back structure. By depositing a passivation layer and local metal contacts on the back of the silicon wafer, the recombination loss on the back of the cell is reduced, and the cell's absorption capacity for long-wave light is increased, thereby improving the cell's conversion efficiency, so that PERC PV modules can convert light energy into electricity more efficiently than traditional PV modules. 

Our PERC PV Module Product Line

KINGSUN’s PERC PV module portfolio is tailored to cover diverse energy scenarios—from tiny off-grid devices to large-scale commercial projects—with two core wafer size series (182cells & 210cells) and 9 power-rated models. Each product integrates PERC’s high-efficiency advantages with scenario-specific design, ensuring you get the right balance of power, size, and cost.

182cells Series (10W-225W) – Flexible Power for Multi-Scenario Use

The 182cells series is our most comprehensive lineup, spanning 10W to 225W. It’s designed for wide adaptability: whether you need a lightweight panel for portable devices or a high-power module for rooftop arrays, this series delivers consistent PERC efficiency (21-23%) and reliable performance. Below is the detailed breakdown:

Series Summary: The 182cells lineup shares consistent voltage parameters (Vmp: 18.27V-18.40V, Voc: 21.47V-21.60V), making it easy to connect multiple modules in series/parallel. It’s the most cost-effective choice for scenarios requiring flexible power matching.

210cells Series (50W-75W) – High-Efficiency for Space-Limited Scenarios

The 210cells series uses larger 210mm wafers, which enable higher power density in a compact footprint (vs. 182cells modules of similar power). It’s optimized for scenarios where space is scarce but efficiency can’t be compromised, with a consistent efficiency of 22-24%.

Series Summary: Both 210cells models share identical voltage parameters (Vmp: 18.24V, Voc: 21.44V) and thin profiles (25mm), making them ideal for integration into space-constrained environments. The larger wafer size also reduces cell-to-cell connection loss, boosting real-world energy output by 3-5% vs. 182cells modules of similar power.

How to Choose the Right PERC Module?

To simplify your selection, follow this 3-step guide based on your scenario:

1. Check power demand: Calculate daily energy consumption (e.g., 100Wh/day → 10W-35W modules; 500Wh/day → 110W-150W modules).

2. Measure installation space: Use our size specs to confirm fit (e.g., narrow rooftops → 55W 182cells or 50W 210cells; large open areas → 180W-225W 182cells).

3. Consider environment: Harsh weather (snow/wind) → choose thicker-frame models (180W-225W 182cells); coastal areas → all models have corrosion-resistant components.

Core Advantages of PERC PV Modules 

Discover our wide selection of high efficiency mono PERC solar panels, available in multiple power classes ranging from 10W to 600W. Each module is engineered to maximize energy yield and minimize LCOE, ensuring optimal performance in all environments.

The following are the core advantages that make PERC PV modules stand out in the field of solar power generation. 

• Higher photoelectric conversion efficiency: PERC PV modules reduce the recombination loss of electrons and holes on the back of the cell by adding a passivation layer and local metal contacts on its back, and improve the absorption capacity for long-wave light, thereby improving the cell's conversion efficiency.

• Excellent weak light response performance: PERC PV modules can also work well and generate electricity in weak light environments (such as early morning, evening, cloudy days, etc.). The passivation structure on its back enables it to have better absorption and conversion capabilities for scattered light and low-intensity light. Compared with traditional PV modules, the power generation under weak light conditions has been significantly improved. This allows PERC PV modules to generate electricity for a longer time during the day, which can effectively increase the overall power generation.

• Good temperature coefficient characteristics: Temperature has a certain impact on the power generation efficiency of PV modules. PERC PV modules have relatively good temperature coefficient characteristics, that is to say, when the temperature rises, the decrease in their power generation efficiency is relatively small. In high temperature environments, PERC PV modules can maintain relatively stable power generation performance. Compared with some traditional PV modules, they can generate more electricity in hot areas or during high temperature periods in summer, ensuring the stability of power generation under different climatic conditions.

• Cost Reduction per Kilowatt-hour: Due to the high conversion efficiency of PERC PV modules, more electricity can be generated under the same installed capacity. This means that during the life cycle of the entire PV power station, its power generation increases, thereby reducing the cost per kilowatt-hour.

• Good compatibility and scalability: PERC PV technology can be combined with other advanced PV technologies (such as bifacial power generation technology, stacked cell technology, etc.) to further improve the performance and power generation capacity of PV modules.

• Strong adaptability to application scenarios: The above advantages of PERC PV modules enable them to adapt to a variety of different application scenarios. Whether in large-scale ground PV power stations, distributed PV power generation systems (such as industrial and commercial roofs, residential roofs), or PV applications in agriculture, transportation and other fields, PERC PV modules can provide reliable clean energy solutions for various scenarios with their efficient and stable power generation performance.
