SolarWorld adds polycrystalline silicon solar cells to monocrystalline production in US

SolarWorld’s Sunmodule solar panels, manufactured in the US using monocrystalline technology, now also incorporate high-performance polycrystalline technology. SolarWorld factories in OR and CA are producing polycrystalline solar panels featuring power densities of 230 and 240W peak.

March 15, 2011 — SolarWorld’s Sunmodule solar panels, manufactured in the US using monocrystalline technology, now also incorporate high-performance polycrystalline technology. SolarWorld factories in OR and CA are producing polycrystalline solar panels featuring power densities of 230 and 240W peak.

SolarWorld’s US-made Sunmodule Plus poly panels maintain the quality, performance and reliability as its monocrystalline panels, with the same lifespan expectation. SolarWorld’s facilities in Hillsboro, OR and Camarillo, CA still undertake every step in the monocrystalline value chain: crystals, wafers, cells and panels. Now they also are ramping up production of polycrystalline cells and panels.

SolarWorld is dramatically expanding supplies of high-performance silicon solar panels of both crystal types at a time of heightened worldwide demand. The company’s US facilities have reached 500MW capacity. 

The basic distinction between the two technologies results from differing processes for crystallizing silicon. In the monocrystalline process, a single cylindrical crystal slowly grows inside a furnace. In the polycrystalline process, molten silicon forms multiple crystal lattices as it quickly cools in a square mold. Also read: Crystalline Si solar cells and the microelectronics experience

The SolarWorld group (ISIN: DE0005108401) provides crystalline solar-power technology from fully integrated solar production. From silicon as the raw material through wafers, cells and modules all the way to turn-key solar systems of all sizes, the group combines all stages of the solar value chain.
