In 2017, pv magazine group launched pv magazine test, together with its partners, Clean Energy Associates (CEA) and Gsolar.
pv magazine test involves a range of indoor tests, as well as an outdoor performance test in Gsolar’s test facility in Xi’an, China. Some of these tests are standard in the industry, while others are innovative and provide data on important module quality and performance issues.
It is the first testing program of its kind to offer comprehensive, independent module testing with an expert third party witness present at all stages of the testing. This is a first in the PV industry, which, up until now, has conducted testing by one party with no outside expert witnesses.
pv magazine test involves a comprehensive series of procedures, addressing the most important issues in module quality and performance, including the following:
- Visual inspection
- EL image inspection
- Low irradiance and temperature behavior
- PID (Potential Induced Degradation) resistance
- LID (Light Induced Degradation) resistance, especially relevant to PERC modules. (Optional)
- Outdoor performance test
The added value of pv magazine test:
- An excellent way to demonstrate your reliability to investors using the high global visibility of the pv magazine trade media platform (print & online)
- Measurements performed in a 1st class laboratory in China
- Expert third-party witnessing of all testing procedures by Clean Energy Associates, a well-known advisory firm that has audited more than 125 manufacturers in the industry.
How does the test work?
Working alongside industry experts from CEA and Gsolar, pv magazine developed a comprehensive module testing program to provide the wide range of data required by PV investors, EPCs, developers and plant operators. The testing procedures are explained in the chart below:
One key aspect is the random sampling method, which ensures the modules being tested represent a cross-section of what is actually rolling off a manufacturer’s production line. More detailed descriptions of the testing procedures, provided by CEA’s Director of Technology and Quality, George Touloupas, are available in the following pv magazine publications:
- September 2017 issue of pv magazine (global edition), Method for the modules
- December 2017 issue of pv magazine (global edition), Building the benchmark

As promised in our article in the June issue, the first outdoor field results from pv magazine test are ready to be presented to readers. After an initial trial period, during which we analyzed the data and solved some technical bugs, the monitoring data started to be collected and recorded in the official test log. The detailed methodology, designed to achieve the best possible accuracy, was described in the June article (pv magazine 06/2018, see below), but we decided to take some extra steps to ensure our data were sound.
The outdoor performance test of PV modules is the single ‘real world’ performance indicator that every buyer is most interested in. As part of the pv magazine test program, Gsolar has prepared an outdoor installation field in Xi’an, China, on the rooftop of a building that houses its manufacturing facilities and the test lab where the pv magazine tests are conducted. Xi’an has a temperate climate, with cold winters and mildly humid, hot summers.
