Panasonic Solar Panels Review
Read our review guidelines
Panasonic is recognized as a leading brand around the world and has been at the forefront of solar technology innovation for over 40 years. The company offers solar panels that are subjected to rigorous testing to guarantee their performance. Known for their robustness and exceptional efficacy, Panasonic’s solar panels have earned widespread respect. In 1998, the company introduced its HIT series, showcasing cutting-edge and highly efficient solar panels.
Panasonic solar panels are among the best in the industry. Their HIT solar panels have a module efficiency ranging from 19.1% and 20.4%, which is slightly below the market leader, SunPower Solar.
These panels beat most big brands in terms of their temperature coefficient and efficiency percentage. They are highly durable and are built to maximize their efficiency while remaining effective throughout their lifetime.
Panasonic solar panels come with a 25-year product warranty and a 25-year linear performance warranty. The comprehensive Triple Guard warranty guarantees that the solar panels will still have a high efficiency of 90.76% after 25 years. Panasonic’s product warranty matches LG’s and exceeds the industry standard of a 10-year product warranty.
Panasonic has been in the market for over 45 years, making it one of the best companies in the world. It acquired its patent from SANYO, which is also a big name in the industry. This company has an incredible reputation, and its experience in the industry assures you that it will be around long enough to fulfill its warranty.
Cell technology
Panasonic solar panels use a unique and efficient HIT cell structure that incorporates crystalline and amorphous technology. This technology ensures the panels retain more power that is usually lost through the conventional crystalline cell technology cells.
The HIT cell technology makes Panasonic solar panels have a high-temperature coefficient of 0.258%, close to SunPower’s temperature coefficient of 0.29%. This specification ensures that Panasonic solar panels lose the least energy during hot summers. These panels also have a low degradation rate.
The first cells of the modules were developed by SANYO Electric, now Panasonic, in 1980. This technology utilized the first amorphous silicon cells in the world. The cells, however, had a low conversion rate which prompted the company to include thin-film poly-silicon and laminated amorphous silicon in their structure.
To eliminate impurities, researchers layered the panels’ cells on an n-type silicon substrate and a non-doped I-type amorphous silicon. This significantly improved the overall efficiency and junction characteristics of the panels.
Panasonic picked up the technology in 1990 and developed its first heterojunction solar cell, the photovoltaic module HIT. The unique heterojunction technology utilizes ultra-thin amorphous silicon layers that reduce energy loss. The HIT range has earned several awards due to its efficiency and high performance and continues to be the industry’s best module.
