Panasonic HIT Heterojunction technology

With a solar system you are making a long-term and high-value investment, hence the quality of the modules is of great importance. Choose a renowned brand that will give you a reliable guarantee and which you can trust.

Experience:

Panasonic is one of the most experienced companies in solar technology. Our experience in this field dates back to the 1970s, when our modules were developed and sold under the SANYO brand. Since then, more than 3 million modules have been sold and installed in Europe alone.

Long-term track record:

We can guarantee our customers decades of trouble-free operation and constant high performance of our modules.

Reliability:

HIT® provides many years of reliable operation over the system's entire life cycle. Out of more than 3 million modules supplied in Europe alone, the failure rate is less than 0.0035% (as of January 2017).

Efficiency:

HIT® is highly efficient and produces more power per square meter than traditional products - up to 28%* (As compared to the average efficiency of 120 different modules on the European market; benchmark values for selected solar modules according to manufacturers' catalogues, December 2009) more. This means that you will need fewer modules on your roof to accomplish very high performance.
 

Our unique technology:

The heart of each Panasonic HIT solar panel is our solar cell. In 1990, scientists at SANYO started developing the heterojunction technology.

This is an improvement on the classic monocrystalline cell, using different materials than a crystalline wafer in the p-n junction.

This invention addresses the key point in a solar technology: reduction of losses at the boundaries of the cell. With this improvement, our heterojunction cells have been continuously breaking records of efficiency and performance at high temperatures ever since. In March 2016, Panasonic set the record for efficiency of a solar panel in commercial size with a panel of 275W (aperture area of 1.1562 m2).

 

Extremely low temperature coefficient: -0.258%/°C

A photovoltaic module Panasonic HIT produces up to 13% more power during daytime with better temperature characteristics.

Our solar module operates most efficiently at around 25° C or 77° F. The temperature coefficient is the indicator of how the performance of your solar panel degrade during hot days. For every degree above 25° C (or 77° F), solar panel’s electricity production will decrease accordingly with the value of temperature coefficient. Therefore the lower value means higher performance.

With the lowest temperature coefficient, HIT maintains higher efficiency and delivers higher output even at high temperatures.
