N-Type EPE Topcon Encapsulants by Vishakha Renewables

Solar panels do a very good job each day by collecting sunlight and converting it to electricity. However, what protects them from dust, high temperatures, or moisture? Encapsulants expand as a durable, silent protector of solar modules to provide safety and efficacy for decades. A good encapsulant help prevent early failures, extension of time to 80% output degradation, or complete failure.

At Vishakha, we have developed new N-Type EPE TOPCon encapsulants, the ultimate solution in embedded functions, much longer life expect breadth of operational output, and enable improved panel output relative or threshold conditions to actively degrade or prevent. Encapsulants have an improved operational range and better durability to provide thermal durability. Encapsulants hold the protective films together while allowing more light to penetrate for a longer time frame. Solar energy will not stay strong and reliable without them.

In this blog, we will explore its encapsulant properties, technical specifications, and energy production benefits.

Key Features of N-Type EPE TOPCon Encapsulants

Just like a soldier needs armor, solar modules need protection to perform their best. And solar encapsulants perform this job right. Without the right encapsulant, panels can wear out faster, lose efficiency, and even fail before their time.

Advanced Technology

At Vishakha, we have created N-Type EPE TOPCon encapsulants, designed to provide the strength and durability solar panels require. These are not just protective layers. They combine EVA (Ethylene Vinyl Acetate) and N-Type POE (Polyolefin Elastomer) to deliver the performance characteristics of both materials. This results in flexibility, improved efficiency, and superior performance against the elements. Whether it’s the scorching heat of summer or the biting cold of winter, this product allows solar panels to operate efficiently.

Multilayer Co-Extruded Design

Notably, their multilayer co-extruded design makes them even more reliable than standard encapsulants. These multilayer products provide additional strength and extend the life of the panels in challenging conditions. Imagine a multi-layer shield, where each layer performs a specific task of protecting the solar cells while optimizing performance. Solar energy is about consistency and durability, so when the encapsulants can offer that, it is a huge benefit.

Optical Transparency

Another benefit of these multilayered encapsulants – the optical transparency – allows even more sunlight to pass through and increases the solar panel’s efficiency. When light is blocked, energy production declines. You will not have to worry about that here. These encapsulants assist the cells in harnessing maximum sunlight so the overall performance is boosted. Along with resistance to PID (Potential-Induced Degradation) will assist in minimizing energy loss over time.

Technical Specifications and Performance Metrics

Electrical Characteristics

An important aspect of the durability of solar modules is their electrical performance. These encapsulants have over 1 × 10¹⁶ Ω·cm for volume resistivity, which offers excellent insulation properties and greatly mitigates the danger of electrical tracking. Similar to a well-built house that offers insulation from all extremes in conditions, this resistivity indicates the operational safety and efficiency of solar cells. The encapsulants are highly resistant to water vapor as evidenced by a very low WVTR that will not allow moisture to infiltrate and negatively impact performance through potential humidity degradation.

Environmental Testing

Environmental conditions are unpredictable and solar panels are faced with every condition imaginable, therefore these encapsulants offer exemplary weatherability for ongoing installations. In all weather conditions, under heat from sunlight to torrential downpour to freezing conditions, these encapsulants maintained performance without failure.

Damp Heat Test Results

Long-term performance is the true test of any solar module. Utilizing a damp heat test it was determined that encapsulants maintained a degradation very close to zero, less than 5% after 3000 hours of exposure per cycle and less than 3% after 1000 hours. Based on the testing process, it can be assumed that after several years of exposure to damp and moisture conditions in heat, the modules will perform reliably.

PID Testing Results

Another noteworthy issue for solar panel owners is the degradation of potential-induced degradation (PID) as this will lead to diminishing power output over time. With less than 3% degradation after 96 hours and less than 5% after 288 hours of test exposure, these encapsulants are proof that PV modules will maintain stable operation in high-voltage exposure.

Benefits of N-Type EPE TOPCon Encapsulants

Enhanced Module Efficiency

A major factor in solar power generation is light transmittance. The more light that passes through the encapsulant, the more energy the panel can produce. These encapsulants are designed for higher light transmittance, which means better efficiency and more power output.

Long-Term Stability

Durability is just as important as efficiency. Solar panels are expected to last for decades, but exposure to heat, moisture, and electrical stress can take a toll. Long-term stability is a must, and these encapsulants are PID-free, meaning they resist the voltage-induced degradation that can reduce power output over time.

Improved Reliability in Harsh Conditions

Harsh weather conditions can be tough on solar modules. From intense UV radiation to heavy rain and extreme temperatures, they face it all. Improved reliability in these conditions means that the encapsulants act as a strong protective barrier, keeping the panels safe from damage.

Ideal for Bifacial Solar PV Applications

Bifacial solar panels, which generate energy from both sides, need encapsulants that support their unique design. Ideal for bifacial solar PV applications, these encapsulants help maximize energy generation by allowing more light to reach the rear side of the module.

Vishakha Renewables: The Future of Solar Encapsulation

Solar modules need efficiency, durability, and protection, and Vishakha’s N-Type EPE TOPCon encapsulants deliver exactly that. Designed for bifacial solar PV applications, they ensure higher energy output, long-term stability, and strong environmental resistance.

For manufacturers, the right encapsulation solution means better performance and longevity. With high transparency, low degradation, and superior durability, these encapsulants help solar modules withstand time and harsh conditions. It’s like choosing the finest materials for lasting results.
