What is solar EVA fiml?

Guangzhou Zanchen New Material Technology Co., Ltd.

Solar EVA film is a widely used encapsulation material in the manufacture of solar photovoltaic modules with the following properties:

Weathering resistance: Solar EVA film is treated with special formulations and processes to provide good weathering and UV resistance, and is able to withstand prolonged outdoor exposure without easy aging.

High Transparency: This film has a high degree of transparency, allowing sunlight to fully penetrate and be effectively absorbed by the solar cells, thus ensuring the power generation efficiency of the photovoltaic module.

Excellent bonding properties: Solar EVA film is able to form strong bonds with glass, backsheets, and other module materials such as solar cells during the lamination process, ensuring the structural stability and long-term reliability of PV modules.

Electrical insulation: As a thermosetting polymer, Solar EVA film has good electrical insulation properties after curing, which helps to protect PV modules from electrical faults.

Low water vapour transmission rate: The low water vapour transmission rate helps to prevent moisture from entering the PV module, reducing the risk of degradation or damage due to humid environments.

In summary, Solar EVA film, as an important component of PV modules, plays a key role in ensuring the performance and extending the service life of PV modules with its excellent weather resistance, high transparency, excellent adhesive properties, good electrical insulation and low water vapour transmission rate.

What are the main differences and advantages between Solar EVA film and solar poe film?

Solar EVA film

Cost-effectiveness: The lower cost of EVA film makes it more competitive in the market.

Processability: EVA film has good processability, easy storage and fast cross-linking, and good adhesion to glass and backsheets.

Weathering resistance: Compared with POE, EVA film has poor weathering resistance and is prone to yellowing in hot and light environments, affecting light transmission and the overall power of the module.

Solar POE film

PID resistance: POE film has superior PID resistance, which is critical to improving the stability and long-term performance of PV modules.

Water vapour and ionic barrier: Due to its non-polar nature, POE film offers better water vapour and ionic barrier, which is critical to prevent module ageing and performance degradation.

Ageing resistance: The molecular chain structure of POE film is stable, and it will not decompose and produce acidic substances during the ageing process, so it has better ageing resistance.

To sum up, Solar EVA film and sola poe film have their own advantages. Solar EVA film is more cost-effective and has better processing performance, while sola poe film has better PID resistance, water vapour and ionic barrier ability, and better ageing resistance.

WHAT ARE THE DIFFERENCES BETWEEN SOLAR EVA FILM AND SOLAR POE FILM IN THE PRODUCTION PROCESS?

The main differences between solar EVA film and solar POE film in the production process are the material costs, the formulation composition and the production process.

Firstly, from the point of view of material cost, the production cost of POE material is usually higher than that of EVA. this is because the production of POE particles as the core raw material of POE film involves a more complex catalyst system, and the domestic has not yet completely broken through the production technology of POE catalyst system. In addition, as the global production capacity of POE/POP is more than 1 million tonnes, compared to China's combined EVA production capacity of 1.772 million tonnes, the degree of localisation of POE is on the low side, which may also lead to cost differences.

Secondly, the formula composition is another important difference. the production process of POE film is similar to that of EVA, but the formula is different, which directly affects the performance of the two materials. For example, EVA is less expensive, easier to process, more resistant to storage, and crosslinks faster, characteristics that make it easier to handle and store during production.

Finally, with regard to the production process, although POE adhesive film is produced in a similar process to EVA, specific production details may vary to suit the characteristics of the respective materials. For example, EVA films may require faster cross-linking speeds and specific temperature controls to ensure product quality.

In summary, the differences between Solar EVA film and Solar POE film in the production process are mainly in areas such as material costs. These differences lead to different market positioning and application scope of the two materials, and also influence the decision of PV module manufacturers when choosing encapsulation materials.

What are the advantages of solar EVA film over solar poe film?

The advantages of Solar EVA film are its lower cost and ease of processing, while the advantages of Solar POE film are its ageing resistance, low water vapour transmission rate and PID resistance.

Firstly, the main advantages of Solar EVA film are its cost-effectiveness and ease of processing. Due to the relatively low cost of EVA materials, it has a competitive advantage in price-sensitive markets. In addition, EVA film is less difficult to process, which makes it easier to handle in production. However, EVA film is susceptible to hydrolysis under light, oxygen, heat and humidity, generating acetic acid, which can lead to corrosion of cell surfaces, solder bands, etc. It also reacts with Na in the glass, generating a large number of free-moving Na ions and causing power degradation.

Secondly, Solar POE film has more advantages in terms of performance. POE film has better aging resistance, which means it can better maintain its performance when exposed to the outdoor environment for a long time, and is less prone to yellowing and degradation. This ageing resistance is critical to the long-term stability and reliability of PV modules. In addition, POE film has a lower water vapour transmission rate, which helps to reduce the impact of moisture inside the PV module and protects the cells from moisture, extending the life of the module.POE film also has excellent resistance to Potential Induced Degradation (PID), which is an important measure of the stability of PV module performance in high voltage environments.The phenomenon of PID can lead to the collection of large amounts of charge on the cell surface, impairing its passivation. The use of POE film helps to reduce this phenomenon and protects the efficient operation of the module.

In summary, Solar EVA film and Solar POE film have their own advantages, and the choice of which material to use depends on the specific application requirements and cost considerations.
