Properties of Transparent Solar Panel Backsheet

Backsheet material is critical to resist environmental factors and increase the life span of solar panels. Today’s premier technology is equipped to create highly specialized polymer backsheets that have increased potential for sunlight penetration. One such leading backsheet tech is visible in transparent backsheet manufacturing. Transparent backsheets are a giant leap over traditional (opaque) backsheets and possess unique qualities that make them a superior alternative to other forms of backsheet.

Vishakha Solar Films is an emerging leader in the manufacturing of high-quality transparent backsheets in India. The company is using cutting-edge technology to manufacture backsheets with inherent capabilities. Vishakha Solar films PV backsheet products include PET, PVDF, PVF, black, transparent and patterned transparent PVDF backsheets that feature high transmission, adequate UV resistance, industry-grade electric insulation, best-in-class thermal stability, and superior moisture/dust protection.

Properties of Solar Backsheets

High Transmission

The re-entrance of sunrays from the backplane is a unique selling proposition of these backsheets and it allows Solar cells to capture albedo radiations. This maximizes the utilization of light and improves output.

Exceptional Moisture-Repelling Qualities

The transparent backsheet has exceptional water-repelling (hydrophobic) properties. The three layer construction utilized in transparent backsheet ensures it becomes highly moisture-resistant. This aligns well with solar panels that are installed in areas with more moisture in the air.

Enhanced Aesthetics

Transparent backsheets have a more aesthetic appeal and stun with their modern and elegant looks. Transparent backsheets are more suitable for buildings and architectural setups where sophistication is a prime requirement. Corporate buildings, high-end apartments, etc. are suitable candidates for transparent backsheet setup.

Aids Solar Cell Performance

Engineered to add more output capacities to the solar cell, these backsheets increase watt-per-cell output. With the ability to transmit more light, transparent backsheets maximize the utilization of solar energy. This increases the total power output.

Lighter than Glass-to-Glass Backsheet Modules

Transparent backsheets are much lighter than the available options for similar functionalities. These backsheets are a better alternative for Rooftop installations where weight is an important criterion owing to the handling of materials.

UV Resistance

UV radiation may have a devastating effect on solar panel components and may degrade the PV components due to prolonged exposure. Transparent backsheets’ unique formulation offers excellent UV resistance and this feature reduces yellowing and degradation of the backsheet.

Dust Barrier

Transparent backsheets maintain the same protective function as traditional backsheets by acting as a dust barrier and protecting the solar cells from dust particles.

Lower Installation costs

Lightweight models have ease of installation and therefore, require less labor. Leading to shorter installation times and reduced labor, transparent backsheets have lower installation costs.

Why is Vishakha Renewables Considered as the Top Manufacturer of Solar Panel Backsheet?

There is a growing trend of bifacial, large-size, high-efficiency, and low costs of the modules in the solar industry. Cutting-edge transparent, superior-quality polyester backsheets are being introduced as substitutes for glass in Bifacial modules or other types of modules where transparency is necessary, such as in greenhouses.

The new transparent backsheets from Vishakha Solar films have impressive performance metrics. It features a high mass efficiency, exhibits low degradation, ensures long-term power output stability, and has a low-temperature coefficient of power.

These backsheets are suitable for diverse environments, including high-temperature regions, dust-prone areas, and seaside locations prone to corrosion.

Vishakha’s Transparent backsheet modules have passed various safety standards, ensuring their fault-proof performance and reliability. They offer a more sustainable solution as they can be recycled through physical disassembly, reducing environmental impact.

Vishakha Solar films, powered by advanced European technology, operates a modern manufacturing facility that accelerates and automates the process. As a result, the company can produce 3 GW of PET, PVDF, PVF based BackSheets.

Value Proposition of Solar Backsheet for PV Modules

Cost Reduction in Specified Market

Transparent backsheets can make a strong business case in markets where importing glass is expensive. By using transparent backsheets instead of glass, solar panel manufacturers can reduce costs and make their products more competitive and cheaper for the end users.

Potential for Commercial and Industrial Market

Transparent backsheets have potential in the commercial and industrial rooftop markets, particularly in areas with flat roofs and moderate weather conditions. These markets can benefit from the use of transparent backsheets due to their lower cost compared to glass and their ability to provide UV protection and durability.

Availability of Raw Materials for Transparent Backsheet

Many component suppliers and backsheet manufacturers are offering solutions suitable for transparent backsheets. This availability of transparent materials, such as Clear Tedlar, transparent PVDF, and ultra-clear PET films, provides manufacturers with options to incorporate transparent backsheets into their solar panels.

Differentiation and Market Demand:

As transparent backsheets are still relatively new in the market, using them can help solar panel manufacturers differentiate their products from competitors. Customers may value the unique features and benefits offered by transparent backsheets, creating a niche market demand that can be capitalized on.

Conclusion

This emerging technology is amidst ongoing adoption and is witnessing widespread adoption owing to its advanced functionalities. Transparent backsheets for PV modules have emerged as a significant innovation in the solar industry, offering a range of advantages and shaping the future of photovoltaic technology.

The new transparent backsheet for solar modules aims to address several challenges faced by manufacturers and users. If we compare the transparent backsheet product with double glass modules, we find that transparent backsheets are lighter and easy to install and their power gain outperform the glass models.
