SANYO Launches its’ Most Powerful HIT® Module Using 21.1% Efficiency CellsTechno Sun
The New HIT® N Series Module Offers More PV Power per Square Metre than Ever Before
Munich, September 2nd, 2010 – SANYO Component Europe GmbH has surpassed its own efficiency record with the launch of its highest efficiency HIT® N Series product. The new HIT-N235SE10 now has 21.1% cell efficiency with a module output of 235W. Shipping of this new module will commence across Europe from this month (September).
Through this New N Series HIT® module, SANYO offers more PV power per square metre offering users additional benefits under the European Feed-in-Tariff scheme and offering a contribution to the lowering of CO2 emissions. SANYO remains committed to enhancing performance and value in limited space installations.
Characteristics of The HIT® New N Series (HIT-N235SE10)
1. World top level module efficiency of 18.6%2
The HIT-N235SE10 has achieved a remarkable 18.6% module efficiency through adopting 21.1% efficiency HIT® cells, new tab design and anti-reflection coated glass. This provides an 8.7% increase in efficiency over and above the 17.1% HIP-215NKHE5 and 7.5% increase in efficiency over and above 17.3% HIT-240HDE4, both of which have a high market penetration in Europe.
All of this helps bring SANYO customers a sense of energy independence by offering them more PV power per square metre.
This high efficiency is based on three technology enhancements:
- High efficiency cell technology (over 21%)
This modules utilizes 21.1% HIT solar cells. HIT® cells have reached 23% efficiency in R&D conditions and these technology learning’s have been implemented into massproduction to realize this 21.1% stabilized efficiency cell. The HIT® cell structure is a mono-crystalline wafer surrounded by ultra-thin amorphous silicon layers, which makes up of superior conversion efficiency and excellent temperature characteristics.
- New tab design
The current N series (HIP-***NKHE5) has connected cells with two tabs whereas the new N series (HIT-N235SE10) uses three (3) tabs which reduces the electrical losses in the cell fingers. In addition to this, through designing new thinner tabs, the effective area is enlarged to capture more sunlight and realize an improvement in efficiency.
- Anti-reflection coated glass:
New N series (HIT-N235SE10) uses anti-reflection coated glass, which reduces losses of reflection and scattering of sunlight. Due to this improvement, more sunlight arrives to the cells and improves the efficiency. This effect is especially noticeable in the morning and evening, when the sun is at a low position; therefore, increased specific yield can be achieved.
2. Production in Europe
The New N Series modules will be produced at SANYO’s factory in Hungary. This factory is currently undergoing a production capacity expansion with capacity to be increased to 315MW within this fiscal year (until end March 2011).
In 1980, SANYO was the first company starting mass production of amorphous solar cells. In 1997, mass production of the high efficiency, high output HIT® Photovoltaic Modules was started.
The HIT® Solar cells (thin mono crystalline silicon wafer surrounded by ultra-thin amorphous silicon layers) are highly appreciated by the market not only by the characteristics of high efficiency and outstanding temperature characteristics but also because of their very high reliability.
In 2004, SANYO Component Europe GmbH, the European sales headquarter was established, followed by the module assembly production site in Hungary in 2005. SANYO Component Europe GmbH is a member of PV CYCLE and is the first member to have signed a binding participation agreement with the organisation.
