 Manufacturing Process |
| |
| The process for fabricating photovoltaic modules consists of the following steps: |
|
- Sorting solar cells into performance groups (current groups at load voltage).
- Assembling and soldering strings of cells interconnected with metal ribbons.
- Completing the module circuit by soldering bus ribbons to connect the strings together and provide output leads .
- Visually inspecting and electrically testing the module circuit by measuring its dark I-V characteristics .
- Washing, rinsing, and drying the glass superstrate .
- Cutting the EVA, fiberglass, and back cover to length and assembling them with the glass and module circuit.
- Laminating the module assembly and curing the EVA.
- Proceeding through final assembly, including edge trimming, installing an edge gasket and frame, and attaching a junction box .
- Performing a high voltage isolation test to guarantee voltage isolation between the cell circuit and the module frame .
- Electrically testing the module performance by measuring a current-voltage curve under simulated sunlight.
