In this work, we train and test a semantic segmentation model based on the u-net architecture for EL image analysis of PV modules made from mono-crystalline and multi-crystalline silicon wafer-based solar cells. This work is focused on developing and testing a deep learning method for computer...
High resolution electroluminescence (EL) images captured in the infrared spectrum allow to visually and non-destructively inspect the quality of photovoltaic (PV) modules. Currently, however, such a visual inspection requires trained experts to discern different kinds of defects, which is time-consuming...
Specifies additional Jenkins plug-ins to install when the container is first run or when OVERRIDE_PV_PLUGINS_WITH_IMAGE_PLUGINS is set to true (see below). Plug-ins are specified as a comma-delimited list of name:version pairs. Example setting: git:3.7.0,subversion:2.10.2. OPENSHIFT_PERM...
Most solar cell production requires the cutting of silicon ingots into wafers. Multi-wire sawing is the dominant slicing technique in the photovoltaic (PV) industry. A multi-wire sawing machine consists of a single bronze coated stainless steel wire up to several hundreds of kilometers long [1]...
coated with a mixture of HMDS and aminopropyltriethoxysilane; DTMS (decyl trimethoxysilane) silica, obtained from Cabot Corporation, comprised of a fumed silica silicon dioxide core L90 coated with DTMS; H2050EP, obtained from Wacker Chemie, coated with an amino functionalized organopolysiloxane; and ...
These are polycrystalline silicon modules manufactured by Axitec. The lower two modules, numbers 1 and 4, consist of 72 cells each while the upper two modules, numbers 2 and 3, have 60 cells each. The nominal powers are 335 W and 280 W. It is assumed that the optical behavior of all ...
Moreover, most previous studies have overlooked the unique color characteristics of PV panels. To alleviate these deficiencies and limitations, a method for extracting photovoltaic panels from high-resolution optical remote sensing images guided by prior knowledge (PKGPVN) is proposed. Firstly, aiming ...

We propose a method to identify and quantify the extent of solar cell cracks, shunting, or damaged cell interconnects, present in crystalline silicon photovoltaic (PV) modules by statistical analysis of the electroluminescence (EL) intensity distributions of individual cells within the module. From ...
Silicon solar modulesPotential induced degradationThermographyElectroluminescenceThe potential induced degradation (PID) of silicon solar modules was investigated in detail in the past years. Nevertheless, even new PV installations exhibit a significant power loss of the system due to PID damage. In this...
