Packing of solar modules Solar panels are typically either horizontally or vertically stacked in a box. Usually, separators are placed between each module, and extra protections are added to the four corners of each module stack. In some cases, modules are also packed in individual cartons boxes to be packed into a large master carton box.
Stress tests are usually used to evaluate module designs in the pre-phase of production, production quality and lifetime of the module. In order to laminate a solar panel, two layers of Ethylene-Vinyl Acetate (EVA) are used in the sequence: glass / EVA / solar cell strings / EVA / tedlar polyester tedlar (TPT). Now it is ready for lamination.
However, despite the massive advancements in technology, basic solar panel construction hasn't changed much over the years. Most solar panels are still made up of a series of silicon crystalline cells sandwiched between a front glass plate and a rear polymer plastic back-sheet supported within an aluminum frame.
METHODOLOGY The first process in solar panel manufacturing is purifying the silicon from quartz sand. Once silicon is purified, it is collected into solid rocks. These rocks are then molten together, forming cylindrical ingots. A steel and cylindrical furnace is utilized to achieve the desired shape.
A junction box is attached to the module using the sealant to firmly attach it to the structure. Connections are then soldered and left for 10-12 hours for curing, so that the structures are perfectly dry and attached properly. The module is then wiped outside to remove any traces or dust, foreign particles or extra sealant.
With the help of an EL test Fig.6, a PV manufacturer can evaluate the structural quality of the PV cells or any other defects generated while handling. Visual inspection of a PV module is performed before and after the module has been subjected to environmental, electrical or mechanical stress testing in the laboratory.
