A factory inspection is the control of the manufacturing steps and processes intended to transform a set of materials into a PV module. The verification of storage areas, components, stages and production parameters is essential to ensure the continuity of performance, durability and safety of modules and therefore of PV plants.

An individual solar cell is fragile and can only generate limited output power. For real-world applications, photovoltaic modules are fabricated by electrically connecting typically 36 to 72 solar cells together in a so-called PV module.
For real-world applications, photovoltaic modules are fabricated by electrically connecting typically 36 to 72 solar cells together in a so-called PV module. A PV module (or panel) is an assembly of solar cells in a sealed, weather-proof packaging and is the fundamental building block of photovoltaic (PV) systems.
The humidity should not go beyond 65% per day and temperature should not exceed 25±5. Before you declare your photovoltaic cell ready, you need to carry out a mirror surface inspection. This step will help give you an assurance that the mirror of the solar panel is in a perfect condition.
While most solar PV module companies are nothing more than assemblers of ready solar cells bought from various suppliers, some factories have at least however their own solar cell production line in which the raw material in form of silicon wafers is further processed and refined.
The schematic process flow for the fabrication of a PV module is shown in Fig. 2. In the interconnection step, solar cells in one column of the PV module are soldered either manually or by a tabber and stringer machine. These strings are typically inspected by electroluminescence imaging to identify defects early on in the production process.
