SolarWorld Solar Panels Earn Top Grade in Revamped PV+ Durability Test

  SolarWorld Solar Panels Earn Top Grade in Revamped PV+ Durability Test

Sunmodule Plus excels against Europe-based laboratory’s new, more stringent
quality criteria

Business Wire

HILLSBORO, Ore. -- July 1, 2013

Solar panels from SolarWorld, the largest solar manufacturer in Europe and the
United States, have earned the highest ranking in the PV+Test, a rigorous
testing regimen that evaluates solar panels according to broad technical and
financial criteria. The company’s Sunmodule Plus SW 245 polycrystalline
silicon solar panel achieved the top grade of “very good,” under this year’s
more stringent assessment standards known as PV+Test 2.0.

Administered by independent testing laboratory TÜV Rheinland and Solarpraxis
AG, the publisher of PV Magazine, PV+Test measures and compares how
successfully solar panels fulfill their claims of quality, power production
and return on investment. Historically, it has evaluated factors such as
electrical safety, production quality, durability and performance guarantee.
This year, the revamped testing regimen adds stricter measures of
temperature-fluctuation and low-light performance, light-induced degradation
(LID) and potential-induced degradation (PID). SolarWorld’s panel far
outperformed a unit from a Chinese producer that did not want its name used in
publicity about the test results, according to study authors.

“In light of mounting concerns about the poor quality of Chinese-made solar
panels, such as those documented recently in the The New York Times, solar
consumers can put their faith in the results of rigorous, independent module
evaluations like the PV+Test,” said Kevin Kilkelly, president of SolarWorld
Americas. “These test results prove what our customers have long known:
SolarWorld quality pays off in terms of financial return and peace of mind.”

Solar panels that undergo PV+ testing are discreetly purchased by TÜV
Rheinland and Solarpraxis through normal sales channels and tested over a
period of several months at TÜV Rheinland's lab in Cologne, Germany. Testers
conduct numerous performance measurements, both before testing begins as well
as after each testing phase, to simulate mechanical demands over the life of
the panel, an important indicator of long-term performance.

PV Magazine called SolarWorld’s performance decisive. An article in the
magazine’s June issue summarized, “As far as quality is concerned … [the]
photovoltaics manufacturer stands out compared with all of the Chinese modules
evaluated in the PV+Test thus far.”

PV+ is just one of many independent tests to document the outstanding quality
and performance of SolarWorld solar panels. These include:

  *North American independent testing firm PV Evolution Lab’s PID-Free
    certification
  *TÜV Rheinland’s Power Controlled and Ammonia Corrosion Resistance
    certifications
  *International Electrotechnical Commission (IEC) 61701 Salt Mist Corrosion
    Resistance certification
  *Global testing and certification provider SGS’s Blowing Sand Resistance
    certification
  *Third-party validated PAN files
