JA Solar PV module
JA Solar 80MW ground-mounted PV power plant in Utah, US.

JA Solar was recognised as an ‘Overall High Achieve’ in the PV Module Index Report 2020 (PVMI) recently released by the Renewable Energy Test Center (RETC).

The recognition from PVMI is for JA Solar’s photovoltaic modules’ excellent performance in strict testing for quality, reliability and performance.

The solar company is one of the three module manufacturers to win this recognition. PVMI was first launched by RETC – an authoritative testing agency in the US – in 2019 in response to market demand.

It is the first report in the industry that comprehensively covers the test results on the three aspects of quality, reliability and performance.

The annual PV Module Index Report evaluates the modules through tests for damp heat (DH), humidity freeze (HF) and thermal cycle (TC), etc., and through the testing results of module efficiency, light-induced degradation (LID) and random sampling, etc.

The report aims to select the modules with the best performance to provide a reference to solar module manufacturers in product technology innovation, high-quality production, and to downstream manufacturers in module selection.

JA Solar PV module ranked among the best

RETC said in the report that in order to select “the best of the best” among multiple module manufacturers, they scored and ranked the manufacturers based on comprehensive module quality, reliability and performance.

“Manufacturers and product lines that achieve high performance according to these three disciplines not only demonstrate a commitment to excellence, but also provide a benchmark – a quantitative measure representing the best that the industry has to offer,” stated the report.

RETC explains that if manufacturer achievements are based off a typical ranking system, it doesn’t necessarily mean that each and every product that the manufacturer makes is good.

The testing agency elaborates: “It also doesn’t guarantee that the manufacturer is able to make consistently good products. It just means that they were on that ranking and that their appearance on it could be based on just one criterion. A manufacturer on a ranking system could fail 90% of all the tests but do amazingly well on one test, and it’s still going to appear in that ranking.”

To resolve this issue, RETC’s PVMI report is made to be as direct as possible. Manufacturers selected as a high achiever by RETC have to tick off all the checkboxes, not just the best in one category.
