Reliability

The true quality of a partnership shows when the going gets tough,
but it will rarely be the case for our customers.
Panasonic HIT is designed to withstand against the worst case scenarios. Reliability is the heart and essence of our engineering.

A quick history of reliability

True reliability has to be proven by time.

Rigorous testings

Since we believe the temperature change is the major cause of failure for solar panel,
our over 20 internal testings include the tripple times longer thermal cycle test than the international standard tests.
HIT performed 23% better than brand A after this regorous testing.

Years of fruitful relationships

Deeds are more persuasive than words.
We have more experience in the photovoltaics business
than other manufactures and are very proud of being
able to present you
with an unprecedented track
record of case studies.

Panasonic internal tests

Forced burning test

While standard burning tests only evaluate flammability in case of an external fire, our internal tests also simulate
a fire outbrake from inside the module.
Even under temperatures as high 1000ºC no fire spreads from the module.

Severe damp heat test

The material is exposed to a high pressure steam test and a temperature and humidity test that is 3 times longer
than required by the IEC [International Electrotechnical Commission].

Cold heat shock test

With shorter cycle times and greater temperature differences durability is tested under more severe conditions
than the IEC requires.

  • Wind resistant test

    Simulates the conditions modules are exposed to during a super typhoon.

  • Durability test

    Replicates the harshest conditions seen in the natural environment by combining strong light temperatures.
