Panasonic is a well known and proven brand, and is celebrating over 40 years in the solar business. They continue to break records for their cell and module efficiency. Panasonic's original SHJ (Silicone Heterojunction) state of art technology solar cell is composed of a thin single monocrystalline silicon wafer sandwiched by ultra-thin amorphous silicon layers. This results in less impurities of the cells, achieving higher electronic quality, and ultimately performance.
In addition, the SHJ solar cell can generate not only front side light, but also rear side light, which enters between the cells, allowing for greater performance in morning and evening light - up to 13% more daily energy production! The pyramidal structure of the cell surface also helps increase the absorption of more sunlight, generating more energy. These HIT solar panels are a proven unique technology and have been in mass production for 19 years, proving to be leaders in the industry.
