The corona pandemic and the resulting restrictions shaped the years 2020 and 2021 immensely. This turnaround that accompanied the crisis was unexpected for many industries. Even the PV industry is still struggling to this day with the effects that have inevitably resulted from the innumerable restrictions. The following effects will continue to occupy us in the coming months:<\/p>\n\n\n\n
As we know, countless manufacturers are trying to counteract the effects of the corona pandemic. For this purpose, cheaper raw materials are used in production, for example, or completely new technologies are even developed. Due to the high demand for solar products caused by climate change, well-known manufacturers create new innovations and technologies almost every month.<\/p>\n\n\n\n
Such new products from major Chinese manufacturers are presented annually at the world’s largest solar PV trade fair, also known as SNEC. Despite the pandemic restrictions, the trade fair was able to take place in Shanghai this summer.<\/p>\n\n\n\n
Vincent Shaw, editor of PV magazine, went among the people in China and attended the world’s largest trade fair. In this article we want you to summarize the impressions and trends gathered by Shaw.<\/p>\n\n\n\n
Due to global restrictions, only a few international visitors were able to take part in the SNEC. At the fair itself, a total of 220,000 visitors from the regional area were identified. Despite the decrease in the number of visitors from the international area, this was a very clear number of visitors. A total of 2,000 companies presented their latest products in front of the visitors. According to Vincent Shaw, various trends among manufacturers quickly emerged.<\/p>\n\n\n\n
These include the following trends:<\/p>\n\n\n\n
N-type crystalline silicon technologies <\/strong><\/p>\n\n\n\n According to Shawn, the n-type cell was very well represented among the manufacturers at the fair. Longi Solar<\/a> and Jinko Solar<\/a> in particular presented innovative products based exclusively on N-TOPCon technology. There were also well-known companies such as Trina Solar, Tongwei and JA Solar<\/a> that use both n-type cells and p-type cells within their production lines. Manufacturers such as Sunport, Canadian Solar<\/a> or Risen<\/a>, who currently only equip their new products with p-type cells, were also represented at the fair. According to Shawn, however, there was a generally positive response to the N-type at the trade fair, so that manufacturers such as Sunport and Canadian Solar also announced that they wanted to switch to the N-TOPCon technology in the future.<\/p>\n\n\n\n Higher performance (520 watts to 800 watts)<\/strong><\/p>\n\n\n\n Due to the increased cell size of 182mm or 210mm wafers, we usually have larger modules with much higher rated outputs. <\/p>\n\n\n\n In the following table we have summarized the respective module formats that were presented within the SNEC with the nominal power supplied with them.<\/p>\n\n\n\n
