Universal Testing Machine (Double Arm) – Solar Testing

The Universal Testing Machine (Double Arm) for Solar Testing — also known as a Twin-Column UTM or Dual-Arm UTM for PV module testing — is a high-capacity, high-precision mechanical testing instrument specifically engineered for the structural qualification of full-size solar photovoltaic (PV) modules, solar panel frames, solar mounting structures, utility-scale racking systems, and large solar assembly components under controlled tensile, compressive, flexural, and shear loading. The twin-column frame provides a rigid, symmetric load path with a large, unobstructed test space — capable of accommodating full-size solar modules (up to 2400 mm × 1200 mm with appropriate fixtures) for IEC 61215 static mechanical load testing, frame pull strength qualification, and module-level flexural and dynamic load testing. Double Arm UTMs for solar testing are the primary structural testing instrument in solar module certification and type approval labs (IEC 61215, IEC 61730, IEC 62782), NABL-accredited PV testing centres, solar panel manufacturing structural QC departments, solar mounting and racking system manufacturers, and solar tracker and utility-scale structure manufacturers. Load capacities from 10 kN to 1000 kN cover the complete range of module-level and structural-level solar mechanical tests that demand higher forces and larger specimen sizes than single arm machines can accommodate. IndiaLaser's Double Arm UTMs for solar testing are built for demanding daily structural laboratory and production-floor use, featuring PC-based digital controllers, programmable crosshead speeds, calibrated load cells with ±0.5% accuracy, large test space with adjustable crosshead, and full compatibility with IEC 61215, IEC 61730, IEC 62782, IEC 62938, ASTM, and ISO solar test standards. Each machine is supplied with solar module test fixtures, calibration certificates, and dedicated UTM software with pre-configured IEC solar test templates for automatic pass/fail reporting.

How a Double Arm UTM Works for Solar Panel Testing

The Double Arm UTM for solar testing operates by applying a precisely controlled, measurable structural load to a solar test specimen and simultaneously recording the force-displacement response. For full-module IEC 61215 static mechanical load testing, the solar module is mounted in the dedicated loading fixture between the twin columns. A uniformly distributed pressure load (2400 Pa for wind and snow load, or 5400 Pa for enhanced load per IEC 61215 clause 10.16) is applied to the module front face, held for 1 hour, then reversed to the rear face — the UTM controller precisely manages the load application rate and hold duration, while continuously recording applied force and module deflection. For solar frame and mounting structural tests, frame sections, rail profiles, bracket assemblies, or clamp components are secured in appropriate fixtures between the crossheads. The controller drives the crosshead at the programmed speed — applying tensile, compressive, or shear load to the solar structural specimen while the calibrated load cell (±0.5% accuracy) and high-resolution encoder (0.001 mm resolution) record force and displacement in real time. The UTM software plots the force-displacement curve, calculates key structural parameters — ultimate load (kN), failure mode, deflection at rated load (mm), stiffness (kN/mm), and pass/fail status against the IEC or ASTM acceptance criterion — and generates a full test report for certification documentation, NABL records, or customer quality assurance files. For cyclic dynamic load tests per IEC 62782, the controller executes the programmed load cycle sequence automatically with full data logging throughout.
