Harnessing the power of the sun: the role of natgraph drying machinery in solar panel production

Applications of natgraph drying technology in solar panel production

The global shift towards renewable energy sources has driven the exponential growth of solar energy adoption. Solar panels, the cornerstone of solar power generation, rely on cutting-edge manufacturing processes to ensure optimal performance and efficiency. Natgraph Drying Machinery has emerged as a key player in the solar panel production industry, revolutionising the drying phase and contributing to the advancement of solar technology. In this blog post, we will explore the crucial applications of Natgraph Drying Machinery in solar panel production, making clean and sustainable energy more accessible than ever before

1. Photovoltaic (PV) Cell Coating

Photovoltaic cells are the heart of solar panels, converting sunlight into electricity. The manufacturing of PV cells involves the application of specialised coatings, such as anti-reflective coatings and protective layers, to enhance light absorption and durability. Natgraph Drying Machinery plays a pivotal role in ensuring uniform and efficient drying of these delicate coatings, leading to enhanced cell performance and longevity.

2. EVA Encapsulation

Encapsulation is a critical step in solar panel production, where Ethylene Vinyl Acetate (EVA) sheets are used to sandwich the PV cells between the front and back glass layers. Natgraph Drying Machinery ensures proper drying of the EVA sheets, eliminating any trapped moisture that could compromise the structural integrity of the panel and its ability to withstand environmental stresses.

3. Backsheet Lamination

The backsheet of a solar panel serves as a protective barrier against moisture, UV radiation, and external elements. Natgraph Drying Machinery aids in the drying of adhesives and coatings during the lamination process, guaranteeing a robust bond between the backsheet and the rest of the panel components.

4. Tabbing and Stringing

During tabbing and stringing, electrical connections are made between individual PV cells to form strings and modules. Natgraph Drying Machinery assists in drying the conductive adhesives used for these connections, ensuring consistent and reliable electrical performance.

5. Transparent Conductive Oxide (TCO) Coatings

Transparent Conductive Oxide coatings, such as Indium Tin Oxide (ITO), are applied to glass surfaces to enhance electrical conductivity in certain types of solar panels. Natgraph Drying Machinery ensures the precise drying of these coatings, contributing to the panels’ overall efficiency and output.


Natgraph Drying Machinery has emerged as a game-changer in the solar panel production industry, optimising critical drying processes and improving the performance and reliability of solar panels worldwide. By ensuring uniformity, efficiency, and durability in the various applications within solar panel production, Natgraph is driving the growth and advancement of solar technology. As solar energy continues to be a driving force in the transition to sustainable power sources, Natgraph’s commitment to innovation paves the way for a greener and brighter future, powered by the boundless energy of the sun.
