Topic of the Week: High-performance PV (Part 4): Three new modules in the series
Yet another expanded series of highly efficient solar modules:
At 370 watts, Sharp’s NU-AH370 offers the highest rated output of the three new modules. With 72 monocrystalline cells, a module efficiency of 19.1 percent and a power tolerance of up to five per cent, it is particularly suitable for large-scale roof-mounted and ground-mounted systems where maximum yields are important. The 1.2 metre long connection cables enable crossover wiring without the need for extra return cables.
The NU-AK310 and NU-AK300B modules, each with 60 cells, are designed for roof systems on residential, industrial and commercial buildings and are available in a variety of designs. The NU-AK310 with a rated output of 310 watts also achieves a module efficiency of 19.1 per cent. The NU-AK300B, with its black frame and backsheet, is particularly designed to appeal to private and commercial customers for whom aesthetics are important. Thanks to an improved five-busbar technology, all modules provide higher reliability and efficiency as well as lower serial resistance. (mfo)
