Solar panel lamination is a critical process used to enhance the protection and durability of photovoltaic (PV) cells and other components. Solar panels typically consist of multiple layers, which are consolidated through a lamination process. This process involves adding an intermediate layer, usually a polymer called POE (polyolefin elastomer), which tightly bonds and protects the solar panel components. POE provides protection against external factors such as temperature and humidity, while also increasing the mechanical resilience of the panels.
Key Benefits of Lamination Process
Waterproofing: Ensures that the panels are waterproof
Impact Resistance: Provides protection against physical impacts.
UV Protection: Shields cells from harmful ultraviolet rays.
Extended Lifespan: Increases the lifespan of solar panels.
Despite these advantages, there are other technologies available to enhance solar panel performance and protection, but lamination remains one of the fundamental methods.
Solar Energy and Lamination Processes in Turkey
In Turkey, flexible solar panel technology and lamination processes are often carried out abroad due to the limited number of local firms, increasing costs. However, efforts are underway to localize these processes through domestic production and technological advancements. We performed the lamination process at Smart Solar Panel Factories.

Our Approach and Goals for Solar Vehicles
1-Efficiency and Weight Optimization
Our goal is to efficiently convert solar energy into electrical energy. We leverage our knowledge and experience in solar panel lamination to optimize factors such as panel placement, cell angles, and material permeability for maximum energy efficiency.
2-In-house Operations
We handle various operations ourselves, including cell soldering, panel layout calculations, and placement of layers such as Frontsheet-POE-Backsheet.
3-Prototyping and Testing
We prototype and test for efficiency, thickness, and weight. Results from our tests so far have not met our expectations. Our goal is to maximize efficiency and lightness through the lamination process in the coming years.

Compatibility with Vehicle Surface
Size
We pay great attention to the materials used during lamination. We use materials with high permeability, lightness, compatibility with each other, and can be laminated in lamination machines in Turkey. In addition, since flexible panels are very sensitive, we solder with a special flux. We try to use flux as little as possible that reduces the light transmittance of the cells.
Use in Electric Solar Cars
Electric solar cars are vehicles that convert solar energy into electrical energy. The solar panels used in these vehicles are placed on the surface of the car and optimized for maximum energy efficiency by optimizing factors such as panel layout, cell angles, and material permeability. Flexible solar panels conform to the aerodynamic structure of the vehicle and enhance performance due to their lightweight. Lamination of these panels enhances durability, ensuring long-term use and protection against challenging environmental conditions that may be encountered during races. As a result, electric solar cars achieve optimal performance in terms of energy efficiency and durability.
