Electroluminescence Camera Systems

Electroluminescence camera systems are available for imaging cracked cells and other defects in still images or video. Solutions are available for the lab from small R&D cells to full modules, and travel systems are available for outdoor testing.  Systems come with a modified DSLR camera, filters, lens, tripod or stand, laptop or tablet computer,  power supply, MC4 cables to place between power supply and solar panel, and instructions for use and image enhancement.

Electroluminescence Testing

EL-Camera Lab System

Low-cost imaging of defects in solar cells and solar panels

EL-Camera Travel System

Outdoor tripod and tablet based system for EL imaging of PV arrays

EL Video Camera demonstration

EL-Video Camera

Real-time high resolution video electroluminescence imaging

UV Fluorescence Test Kits

UVF is a fast method to detect cell cracks and hot spots in aged modules. We offer a low-cost handheld flashlight kit for detection by eye, and a high-throughput camera flash based system which can image up to 1000 modules/hour.

Ultraviolet fluorescence testing solar panels

Basic UV Fluorescence Kit

Small hardcase with filtered UV Flashlight, eye protection, and spare batteries. Shine on aged modules at night to detect cracked cells and other defects. No disconnection of modules needed.

BrightSpot UVF PRO Camera System

PRO UVF Camera System

High throughput UVF camera-flash based system for testing up to 1000 modules/hour by pole mount or 5000 modules/hour by drone. No disconnection of modules needed. Hardcase with camera, filtered flash unit, tall handheld monopod and harness, UV flashlight, tripod, and GPS.

Photoluminescence and Electroluminescence Cell/Wafer Testing

CellSpot-EL/PL

EL/PL Wafer and Cell Tester
Budget-priced system uses a safe red LED PL light source and a high resolution camera within a lightproof enclosure to obtain contactless images of wafers and partially/fully processed cells. Can be configured to look at a single cell within a module or an entire row/column with multiple light sources. Light sources available separately. Cell probing stage available for EL with a switch box for measuring in forward bias (normal), reverse bias (see shunts), and shorted case (remove noise from encapsulated coupons).

Measure Contact and Line Resistance
LoadSpot-product

ContactSpot

  • Fast measurement of contact resistivity for solar cell grid structures
  • More accurate and lower variability than using manual probing
  • Advanced algorithms for voltage drop down narrow fingers, for current spreading through the wafer thickness, and for non-destructive testing of circular structures.
  • Also measures line resistivity.
Load Testing with EL
LoadSpot

LoadSpot

Solar Panel Crack Detector and Mechanical Load Tester
The LoadSpot performs static and cyclic (dynamic) load tests for standard IEC certification testing. Bending tests are performed by applying vacuum or air pressure to the rear side of the module, leaving the front side open for EL and IV testing.
