A Complete Review of Panasonic Solar Panels

SolarKobo Score: 4.7/5 stars


Manufacturer's Profile

The makers of Panasonic solar panels, Panasonic Corporation, is a Japanese multinational electronics company founded March 13th 1918 in Osaka, Japan. Until 2008, its corporate name was ‘Matsushita Electric Industrial Co., Ltd.’ In 2008, it became Panasonic Corporation. Panasonic has sold its products under brand names like National, Sanyo and Technics. Since the 2000’s and beyond, Panasonic gained footing in the global market for numerous achievements as a tier-one manufacturer in all markets they serve. Notably, In July 2014, it was announced that Panasonic had reached a basic agreement with Tesla Motors to participate in their mega battery plant in the United States, the Gigafactory 1. Since the 2016 opening of the Gigafactory in Nevada, Panasonic has developed a new battery technology for the “2170” lithium-ion cells it produces and supplies to Tesla. In early 2020, Panasonic announced that it would be leaving the Tesla deal.


Panasonic began making and selling amorphous solar panel modules, an old style thin film technology, under the brand name SANYO, until 1997 when they transferred to their staple HIT™ range of solar panels. Till date, it has sold over 4 million panels in Europe alone.


Panaserv is an official distributor of Panasonic products in Nigeria.


The End of An Era?

On February 1, 2021, Panasonic announced that it will be ceasing the production of solar products at its Malaysian and Japanese factories. Panasonic also said it would completely be exiting the solar panel and wafer market by March 2022. It will however continue selling Panasonic-branded modules but through a subcontracted manufacturer.


HIT Technology

The unique Heterojunction technology (HIT™) cell structure used by Panasonic sandwiches ultra-thin layers of amorphous silicon between the crystalline silicon substrate. It incorporates both crystalline and amorphous technology into the cell to retain the power that is often lost through conventional crystalline cells at the p-n junction. (Read our article on the types of solar panel technology here for a heads-up) The goal is to reduce unwanted energy losses at the boundaries of the cell.

The HIT™ technology has an extremely low temperature coefficient of .258% loss for every degree Celsius above 25 degrees, making it able to produce up to 13% more power during daytime. Th
