India Solar Encapsulation Market Overview, 2030

The solar industry in India has grown significantly in recent years, exceeding 100 GW of installed capacity, which has created specific requirements for module dependability and efficiency. Given the country's hot, dusty, and humid weather, solar modules need to endure high temperatures, dirt accumulation, and potential-induced degradation (PID), making the choice of materials for encapsulants vital. At first, manufacturers in India heavily depended on imported ethylene-vinyl acetate (EVA) encapsulants, which frequently did not provide adequate UV stability or anti-PID properties suitable for local conditions. To combat this, local suppliers and module manufacturers have advocated for formulations that merge UV-stable EVA with polyolefin elastomer (POE) blends, as well as treatments specifically aimed at preventing PID. These advancements improve long-term dependability, lessen degradation in high-stress situations, and lengthen the lifespan of modules in severe operational settings. Research and development pursuits are being directed toward cost-efficient POE formulations that offer superior heat and moisture resistance than standard EVA while still ensuring ease of processing and adhesion. Quick-curing encapsulants are also being emphasized to boost efficiency in local lamination facilities, aiding India’s growth objectives without sacrificing quality. Focusing on locally compatible substances decreases reliance on imports, minimizes supply chain vulnerabilities, and lets manufacturers customize performance for specific environmental challenges like significant dust buildup, temperature fluctuations, and humidity during monsoon seasons. All in all, these improvements in encapsulant materials UV-stable EVA/POE blends, anti-PID treatments, and quick-curing options illustrate the development of India’s solar ecosystem, where rapid growth is accompanied by an increasing emphasis on long-lasting module reliability and performance enhancement. As India expands its solar capacity, these material innovations will play a crucial role in ensuring high energy outputs, reducing operational wear, and aiding the country’s ambitious renewable energy goals.

According to the research report ""India Solar Encapsulation Market Overview, 2030,"" published by Bonafide Research, the India Solar Encapsulation market is anticipated to grow at more than 9.41% CAGR from 2025 to 2030. India's market for solar encapsulation is currently experiencing a swift expansion, fueled by two main factors large utility-scale solar parks and government-supported rooftop subsidy initiatives like PM Surya Ghar Muft Bijli Yojana. This growth is driving a significant need for high-quality encapsulants, with a notable shift towards anti-PID (Potential-Induced Degradation) grades that protect module performance in the high-voltage, high-humidity conditions frequently found at numerous Indian project locations. Concurrently, the domestic supply chain is growing, aided by policies that aim to decrease reliance on imports. Local producers are putting money into backward integration for EVA, POE, and other films used for encapsulation, while global companies maintain their presence in the market through partnerships and distribution channels. Significant industry participants include RenewSys and Vishakha Polyfab, along with international providers offering specialized formulations designed for the specific climate and operational scenarios in India. The Production Linked Incentive (PLI) Scheme for highly efficient solar PV modules is further enhancing opportunities, promoting the integrated manufacturing and local sourcing of essential components like encapsulants, as part of the Ministry of New and Renewable Energy's goal for a self-reliant Bharat. Additional incentives for domestic production, tariffs on imported modules and cells, and the Approved List of Models and Manufacturers (ALMM) system are reinforcing the justification for local manufacturing. Adherence to BIS (Bureau of Indian Standards) certification and IEC international testing requirements is now mandatory for entering the market, ensuring that modules comply with rigorous performance, safety, and durability criteria. These certifications also improve bankability by minimizing perceived technical risks for investors and reducing warranty claim liabilities for producers. As India’s solar capacity progresses toward its 2030 non-fossil fuel objectives, encapsulation is becoming not only a protective mechanism but also a vital factor for sustaining long-term energy output, reliability throughout the lifecycle, and competitive edges within an evolving domestic solar manufacturing landscape.

The solar industry in India by materials is divided into Ethylene Vinyl Acetate (EVA), Thermoplastic Polyurethane (TPU), Polyvinyl Butyral (PVB), Polydimethylsiloxane (PDMS), Ionomer and Polyolefin reveals unique trends in encapsulants influenced by local climate variations and project needs. Ethylene-vinyl acetate (EVA) remains the primary choice for affordable, large-scale solar installations throughout various parts of the nation due to its reliable supply chain, established durability, and cost efficiency. EVA modules are commonly used in areas with mild climate stress, prioritizing economic viability and mass production. Conversely, in more demanding climates, other encapsulants are becoming more popular. Polyolefin elastomer (POE) is increasingly utilized in Rajasthan and similar hot, dry areas, where extreme heat, high levels of solar radiation, and significant risks of potential-induced degradation (PID) threaten typical EVA modules. POE provides better resistance to high temperatures, water penetration, and PID, resulting in enhanced dependability and extended service lives under such intense conditions. At the same time, polydimethylsiloxane (PDMS) is being evaluated for use in India’s deserts, where modules experience drastic temperature changes, considerable dust buildup, and strong winds. The thermal resilience, water-repellent characteristics, and adaptability of PDMS make it a potentially suitable option for these extreme environments, although its higher price and limited large-scale use hinder its widespread application to experimental or niche projects. These developments reveal a strategic differentiation within India's solar encapsulant market EVA targets large-scale, budget-conscious initiatives; POE focuses on reliability and longevity in challenging areas; and PDMS is investigated for extreme desert situations. By matching the choice of encapsulant to local climate issues, Indian producers can enhance energy production, minimize wear, and sustain long-term module effectiveness. This differentiated strategy helps support the country's ambitious renewable energy goals while balancing affordability, dependability, and environmental resilience across various landscapes.

In the solar sector by technology is divided into Crystalline Silicon Solar and Thin-Film Solar, crystalline silicon (c-Si) remains the leading technology used in most installations, thanks to its established efficiency, durability, and a solid manufacturing framework. Both monocrystalline and multicrystalline panels are frequently used in large-scale and commercial ventures, where high energy output, enduring reliability, and consistent performance are crucial. The vast global supply network, uniform panel sizes, and advanced processing methods render crystalline silicon the favored option for developers pursuing scalable, economical, and effective energy production. Conversely, thin-film solar technologies, like cadmium telluride (CdTe) and the new perovskite cells, are mainly being tested in specialized areas where their distinct characteristics provide benefits over crystalline silicon. An important instance is floating photovoltaic (FPV) initiatives; thin-film panels are typically lighter and more flexible, which makes them suited for installation on bodies of water such as reservoirs, lakes, and irrigation tanks. Moreover, thin films generally show better performance in hotter conditions, which is beneficial in certain climates. Rooftop pilot initiatives, especially in urban or limited spaces, also gain from thin-film panels due to their lighter weight, versatility, and ability to blend aesthetically with building surfaces. These trials give developers the chance to evaluate long-term efficiency, sturdiness, and cost-effectiveness in real-world scenarios while gradually introducing different technologies into the market. While the uptake of thin-film remains small compared to crystalline silicon, ongoing testing reveals its potential to support mainstream solar, particularly in scenarios where land is scarce, structural limitations exist, or environmental factors render traditional panels less feasible. By fusing the reliability of crystalline silicon with the versatility of thin-film options, the solar industry can enhance energy generation across various locations, bolster system robustness, and set the groundwork for next-generation solar technologies.

The solar energy landscape in India by application is divided into Ground-mounted, Building-integrated photovoltaic, Floating photovoltaic and Others (Automotive, Construction, and Electronics) is very varied, with several segments serving distinct energy requirements and regional characteristics. Utility-scale projects are primarily dominated by large ground-mounted solar parks, especially in states such as Rajasthan, Madhya Pradesh, and Karnataka. These expansive setups, often featuring capacities of hundreds of megawatts, deliver affordable energy production, efficient capacity use, and reliable integration into the grid, forming a crucial part of India’s push towards renewable energy. In cities, building-integrated photovoltaics (BIPV) are increasingly popular, particularly in smart cities like Ahmedabad, Pune, and Bengaluru. BIPV systems allow solar panels to substitute traditional building materials, such as roofs and facades, thus generating power while maintaining the aesthetic appeal of architecture and making the most of limited city spaces. Floating solar technology is developing as a viable solution in regions abundant with water, particularly in Kerala and Gujarat. Installing solar panels on bodies of water like reservoirs, lakes, and irrigation ponds minimizes land use conflicts, utilizes the cooling benefits of water, and can produce more energy compared to standard ground-mounted systems. Ongoing pilot and commercial projects in these regions are showcasing the effectiveness and economic advantages of this approach. On a smaller scale, solar streetlights are becoming more prevalent across India, offering off-grid lighting solutions for rural, semi-urban, and peri-urban areas. These systems enhance energy access, decrease reliance on traditional electricity sources, and contribute to local sustainability efforts. These segments depict a comprehensive strategy for solar deployment mega parks optimize output, BIPV incorporates energy generation into urban spaces, floating solar utilizes water bodies for scalable energy, and streetlights facilitate decentralized energy access.
