AVENTIA solar modules are produced in the European Union under the strictest quality standards, in state-of-art manufacturing facilities and undergo several major inspection procedures including:
- 3 times EL testing to ensure end product without micro cracks, opposed to 1 or 2 times by other manufacturers.
- 3 times appearance inspection to ensure no defects, opposed to 1 or 2 times by other manufacturers.
- 1 time power testing and inspection to ensure expected power output is being delivered from each and every solar panel.
This way we are able to guarantee reliable products, perfect appearance and positive power performance.
Cell selecting: Selection of the primary component of the panel.
Automatic welding: The welding machine connects the cell with the PV ribbon through non‐contact infrared welding.
Lay-up: Connecting the cells by string connector and placing the EVA and backsheet. The panel can produce electric current from now on but it’s still fragile before lamination.
Inspection before lamination: Inspecting appearance and removing any foreign material then second inspection by EL testing machine, in order to spot possible defects such as microcracks.
Lamination: The panel goes through the lamination encapsulation process, then the cells, EVA, Backsheet and Glass combine organically and the panel obtains initial physical integrity and is considered a semi‐finished product.
Edging: edging by removing excess material from EVA and Backsheet.
Visual inspection: The panel is turned mechanically to 90° so that it can be inspected from every angle and qualify to the next production procedure.
EL testing: Electroluminescence testing after lamination and for the second time is another procedure necessary in order to ensure once more the quality of the product.
Framing: Automated Framing and sealing at the same time. With the automatic sealing machine, the silicone is being applied smoothly and evenly. The junction box also will be installed during this procedure.
Pre‐cleaning: Cleaning the extra silicone gel from all parts of the panel after framing.
Solidification: Panel enters the solidification room, under 70% RH humidity, and remains there for more than 3 hours. This procedure provides silicone with preliminary curing and ensures it maintains the required properties.
Cleaning: Cleaning of the solar panel and connecting each connector to the junction box.
Electrical properties testing: Testing I‐V output performance through Simulator power test.
EL testing: Testing the finished panel by electroluminescence testing machine for the third time will ensure a high quality end product.
Final inspection: Inspecting once more the panel from front to back will ensure that the panel appearance meets our high standards.
Packing and storing: Packing the finished panel and storing them in the warehouse ready to be shipped anywhere in the world.
