Global PV cell production grew to an impressive 37.2 GW in 2011, according to a market survey by PHOTON International - The Solar Power Magazine, for a 36-percent increase over the 27.4 GW produced in 2010.
But the annual survey also reveals a dramatic reduction in year-on-year growth. Compared to a record 120-percent jump in 2010, the 2011 cell output was the PV industry's lowest growth rate since a 34-percent increase in 2003. The survey also shows a continuation of Asian dominance, with six Chinese manufacturers in the top 10 - with Suntech Power in first place for the second year in a row - and two from Taiwan. For the first time since PHOTON International began surveying solar cell producers, the top 10 did not include any solar cell producers from Europe or Japan.
"The days of solar cell production in western countries are numbered," says Michael Schmela, editor-in-chief of PHOTON International. "Like other commodities, solar cell production will continue its rapid shift to low-labor-cost countries in Asia, especially China." In 2008, only 33 percent of solar cells were made in China, a share that grew to an impressive over 57 percent in 2011.
Mersenís new HP10J photovoltaic fuse line provides superior overcurrent protection at the re-combiner box and inverter levels and covers applications ranging from 70A to 400A, 1000VDC. The enhanced fuse construction of the HelioProtection series makes it ideal for continuous temperature and current cycling withstand adding to system longevity. Low minimum breaking capacity capabilities of 1.35 times the fuse-rated current value allows for safe circuit interruption under typical low-fault current conditions produced by PV arrays.
