During the March 2017 review, more than 20 interested parties suggested separating the duty MIP for mono-crystalline and poly-crystalline products. These parties included Union producers, European companies, solar industry associations, Malaysian exporters, and the Chinese government.
Mono-crystalline products are more expensive than poly-crystalline products due to their higher output per area of space. According to price quotes from PV Insights, the average price difference between mono-crystalline and poly-crystalline modules was €0.047 per watt and the difference between poly-crystalline and mono-crystalline cells was €0.040 per watt from January 2014 to March 2017.
The distinction makes sense as the Union industry seems to focus on manufacturing high-end mono-crystalline products for rooftops while importers and engineering, procurement and construction companies (EPCs) were active in the utility-scale sector which utilizes poly-crystalline modules.
