Mechanical load tests are a commonly-performed stress test where pressure is applied to the front and back sides of solar panels. In this paper we review the motivation for load tests and the different ways of performing them.

The current industry standard dynamic mechanical load (DML) test protocols for solar photovoltaic (PV) modules do not subject modules to the types of pressure fluctuations that occur in real-world scenarios.
Mechanical Load Testing • Replicate stresses related to snow and wind loads • Part of panel certification testing sequences since early JPL Block V Tests (1981) • IEC 61215 – Static test: 3 cycles of 2400 Pa, 1 hour on each side of panel (static) • IEC-TS-62782 – Cyclic (dynamic) test: 3-7 cycles/min, +/- 1000 Pa
IEC TS 62782:2016(E) provides a test method for performing a cyclic (dynamic) mechanical load test in which the module is supported at the design support points and a uniform load normal to the module surface is cycled in alternating negative and positive directions.
Mechanical Loading (ML) tests as a general test of module strength. ML test has long been hailed as the de-facto test for evaluating the mechanical strength of solar modules, especially with IEC 61215 having included the 6500 Pa requirement for passing the standard.
