Suntech has exhibited its polycrystalline PERC anti-soiling module’s at the World Future Energy Summit in Abu Dhabi, claiming Middle East markets show “infinite potential” for its products and aiming to establish a foothold in the sunny desert environment.
The anti-soiling modules are well suited to desert conditions: compared with standard modules. Research suggests dust can be a major problem for solar panels, reducing power up to 30% or even up to 100% if cementing of the dust occurs. According to the Photovoltaik-Institut Berlin (PI), no PV standard exists for soiling, cleaning and abrasion of solar cells – PI’s research finds that the stress of cleaning may have an impact on solar panel reflectivity, and therefore yield. Suntech says its anti-soiling modules can effectively reduce dust accumulation, cut the cost of surface cleaning and maintenance, and improve power by approximately 1.3%.
Suntech is keen to develop the United Arab Emirates and the Middle East as an important customer base. “China and the UAE became friends because of the Silk Road, so it’s natural that the two countries would partner in building the Belt and Road. Meanwhile, the UAE has excellent geographical conditions, particularly with annual solar radiation averaging 2,000-3,200kWh/m². Most areas have more than 2,400 hours of sun exposure annually. In 2018, the installed PV capacity reached 625MW for a ranking of second place in the Middle East. At the same time, the demand for PV installation in nearby Jordan, Qatar and Oman is high,” said the company.
As well as its anti-soiling line, the company displayed its “new favourite” P-type monocrystalline double-glass bifacial module, which Suntech said can increase power generation by as much as 25% and comes with a 30-year linear warranty. “The P-type monocrystalline double-glass bifacial technology represents the future of the PV modules,” said the company.
