Solar encapsulation is the technique of preserving solar cells from external elements such moisture, UV radiation, and mechanical damage. It entails sealing the solar cells with protective coatings, often polymers such as EVA (Ethylene Vinyl Acetate), in order to improve their endurance and performance. This encapsulation assures long-term efficiency, electrical insulation, and the optical transfer of sunlight to cells. It is an essential component in the production of solar modules, considerably increasing their longevity and reliability.

Solar encapsulation is an important procedure in photovoltaic (PV) module manufacture because it protects solar cells from moisture, UV radiation, and mechanical stress. It employs specific polymer layers such as EVA, POE, or PDMS to improve durability, electrical insulation, and light transmission. Demand for high-performance encapsulants is increasing as solar technologies like as bifacial and perovskite become more advanced. Effective encapsulation has a direct impact on a solar panel's efficiency, stability, and resistance to environmental degradation.

Solar Encapsulation Market Insights

With rising concerns about climate change and carbon emissions, countries around the world are rapidly transitioning to renewable energy sources. According to the United Nations, fossil fuels such as coal, oil, and gas continue to be the most significant contributors to global climate change, accounting for more than 75% of greenhouse gas emissions and over 90% of total carbon dioxide emissions worldwide. The scientific agreement is clear: to avert the most catastrophic effects of climate change, emissions must be reduced by roughly half by 2030 and net-zero by 2050. The urgent need to reduce greenhouse gases and meet global climate targets is boosting the adoption of renewable energy, notably solar power, which drives increased demand for efficient and durable solar encapsulation materials.

Governments are facilitating this transition by providing tax breaks, subsidies, and financing to encourage solar energy use. According to the Ministry of New and Renewable Energy (MNRE), the Government of India has launched the PM Surya Ghar: Muft Bijli Yojana to promote sustainable development and increase people's well-being. With an investment of more than Rs. 75,000 crores, this effort seeks to supply up to 300 units of free power each month to 1 crore families. Such strong government support is projected to promote the solar encapsulation industry by increasing demand for essential solar panel components. These initiatives contribute to the expansion of solar infrastructure, hence increasing the requirement for reliable encapsulation solutions.

While sophisticated encapsulants such as ionomer and PDMS provide improved durability and performance, their high starting prices can be challenging for smaller firms and impede wider use. Nonetheless, the increasing installation of rooftop and off-grid solar systems globally creates considerable opportunities for the business. For example, in November 2022, LONGi Solar Technology Co., Ltd. reported the successful delivery of 406MW of its bifacial Hi-MO 5 PV panels to a solar plant built by PowerChina SEPCO III as part of Saudi Arabia's Red Sea Solar PV Project. This 400MW solar project is considered as the world's largest off-grid energy storage venture. The widespread use of these bifacial PV panels raises demand for solar panel components, including encapsulation materials, resulting in growth in the solar encapsulation market.
