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.
Here is a quick history of our reliability.

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.

IEC 61215 Thermal Cycle Test Result

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.

100% Panasonic integrated production

We have the highest standards on all levels of production. In order not to corrupt these standards,
we produce everything ourselves, even from the "ingot" which is the literally the fundamental building block of a solar system.

  • Shipping

    After rigorous inspections,
    the products are carefully
    packed and shipped.

A highly pure ingot is procured
from suppliers all over the world
including our Oregon Factory.

Diamond wire saws slice
the ingot into wafers
that are thinner than a postcard.

A better slicing technique yields
a larger number of wafers
from the same quantity of ingots.

Each sliced wafer becomes
a substrate of heterojunction cells.

The silicon wafers are cleaned
of impurities and texturized

※ texture: small pyramidal shapes formed
on the wafer surface for the light confinement.

Amorphous silicon layers
form hetero-junctions.

Transparent eletrode layers and
charge-collecting grid electrodes are formed,
resulting in heterojunction cells with the world highest level power generation performance.

The power generation performance,
appearance and other characteristics
of each cell are inspected.

Connect cells in series by wiring
material to form “strings”.

Set the strings to the tempered glass, encapsulant, and the backsheet, and then laminatethe module.

After installation of frames and a junction box, conduct the multiple inspections whichexceeds the international standards.

Only products that pass these
inspections are shipped to our
customers all over the world.
