Photovoltaic technology has become increasingly important in the quest to develop renewable sources of energy. It is also becoming increasingly sophisticated. In 1980, Sanyo was the first company to mass produce amorphous solar cells and the company’s latest development capitalises on over 35 years of experience in photovoltaic design and manufacture. The intention is to marry attractive design with truly sustainable performance
Sanyo has just launched a new solar panel, the HIT-N240SE10, with a cell conversion efficiency of 21.6 per cent
The new solar panel measures 1580 x 798mm and is made up of a series of interconnected photovoltaic cells. Each cell contains three tabs (as opposed to the more usual two), aimed at reducing electrical loss in the cell fingers. The tabs are also thinner, a mere 35mm thick, so the effective area is enlarged to capture more sunlight, thus improving efficiency.
The cell structure is composed of a mono-crystalline wafer surrounded by ultra-thin amorphous silicon layers, which have excellent temperature response values and give superior energy conversion rates. Panels are finished in anti-reflection coated glass that reduces the reflection of sunlight, so more of the sun’s energy is captured by the cell. This effect is noticeable in the morning and evening, when the sun is at its lowest in the sky. The HIT® New N Series gives Sanyo customers an enhanced sense of energy independence by giving them more photovoltaic power per square metre for their investment.
