State of the art technology: Heterojunction solar cell
The solar cell of photovoltaic module HIT™ is original hetero-junction type which is composed of mono-crystalline and amorphous silicon layers. Amorphous siliocn layers in the cells prevent recombinations of electrons and minimize the power loss; realizing industry leading level performance of generation.
*”Hetero” is a prefix originating from Greek word meaning “different”
More power generation in limited space
Panasonic HIT™ is one of the most efficient solar panels in the world.
Thus it enables more power generation per square meter than conventional solar panels.
High performance at high temperature
At noon, with the sun shining bright, the surface of solar panels can heat up. With standard solar panels, this can affect their performance. However, Panasonic HIT™ has a unique structure that allows them to maintain high efficiency and performance even in hot temperatures, and so allow HIT™ to produce more energy throughout the day.
Power generation from both sides of module
Panasonic's bifacial solar panel captures sunlight from both sides of the panel simultaneously, by using Panasonic's proprietary bifacial heterojunciton solar cells.
The photovoltaic module HIT bafacial type has two glass layers, which allow a portion of sunlight to pass through the panel. The sunlight that has passed though the solar panel along with the light reflected off surrounding surfaces, is captured by the back face of the panel, increasing the amount of energy produced by up to 30% compared bto single-sided Panasonic HIT.
At panasonic, we aim to produce products with a maximum lifetime expectancy. Our internal testing standards are well above international standard requirements.
The outstanding Panasonic quality is also proved by third-party certificates, such as the TÜV long term sequential test.
The TÜV Rheinland long term sequential test method proposes to simultaneously evaluate multiple stresses on two identical PV modules.
The modules undergo multiple stress tests consecutively instead of the usual certification testing case where each module is subjected to only one stress test. Our HIT™ VBH210SE10 passed this test in 2013.
Panasonic HIT™ complies with the directive restricting for the use of certain hazardous substances in electricts the use of hazardous materials, such as lead, cadmium, and mercury, used in the manufacture of electrical and electronic equipment.
Panasonic HIT™ has been tested and confirmed by Fraunhofer Center for Silicon-Photovoltaics (CSP) for potential induced degradation (PID) resistance.
