Shortage and delay in solar module supply are argued to be one of the most important factors that lead to delay in solar project deliveries globally.
The most influential reason of delay in solar module supply was shortage of glass supply few months ago. We are also talking about increase of polysilicon, wafer and cell prices today. In addition to all these, the serious shortage of shipping containers which has steadily been growing since mid-last year.
Not finished yet, strong development of large-scale PV projects in China, EU and USA may boost the increases of solar module prices globally.
Briefly, solar industry faces solar module shortage and price increase again, as usual.
And one note: I think Emiliano Bellini ‘s article on PV-Magazine about relation between solar modules and silver is really interesting and worth to read. He provides a different perspective.
