The Solar Industry has run into stiff competition for further feedstocks of polysilicon which is used to make PV arrays. The shortage has boosted prices from $30/kg to $70/kg. Polysilicon is used to make computer chips, and historically its use in solar was only a 1/3 of amount used for chip production. With new incentives in place, solar use of the silicon will be greater than chip production for the first time.I have noticed a trend forming at online solar stores as well. Many choices are "back ordered" until the spring or summer of this year.
Not to fear, polysilicon suppliers are investing in increased production this year. Until then, don't expect any discounts on PV panels, despite it becoming more mainstream.Link to Article: MSNBC. Notable quote:
