Panasonic’s quality of solar panels comes from a forty-year experience in the photovoltaic industry.
Panasonic Solar Panels: decades of development
Already in the early 1980s Sanyo (old brand with which Panasonic modules are now sold) had begun to develop amorphous silicon cells.
The development of the current high efficiency HIT cells (Heterostructure with Intrinsic Thin Layer) proprietary cells began in the early 1990s, and thanks to this, but not only now, Panasonic has been able to guarantee its modules for both manufacturing defects and performance losses for 25 years.
Panasonic is confident of its modules since the problems encountered in Europe since 2003 are less than 0.005% over more than 3.7 million of the modules sold.
Many tests guarantees top quality
These fantastic performances are due to the fact that Panasonic internally leads over 20 internal tests with much higher standards than the international certifications required.
Among Panasonic’s tests, these are particularly hard-fire tests that, in addition to assessing flammability from external causes, also simulate indoor outbreaks at the module with test temperatures of over 1000°C and the result is that there is no spread of flows to other modules.
The test of a wet hot resistance is performed three times more than the international standard of IEC regulation, while the cold cycles test is carried out with shorter cycles and higher differential temperatures, therefore with more severe conditions than required.
Panasonic modules also undergo a wind test that plays a typhoon.
In addition to internal tests, Panasonic’s quality is also confirmed by external certification bodies such as:
- The TÜV long term sequential test
- The TÜV Fire test, class 1
- PID free (Potential Induced Degradation)
- Salt-mist corrosion test, severity level 6
Panasonic prefers to demonstrate with the facts the quality and performance that he has without false promises.
Panasonic solar panels are distributed from VP Solar, specialized in energy systems from 1999.
