Worldwide PV manufacturing equipment billings and bookings remained flat in the third quarter of 2012 compared to the previous quarter, according to global semiconducter trade association SEMI.

In its Worldwide Photovoltaic Equipment Market Statistics Report, SEMI said the reported $234 million in bookings is 56% below the third quarter of 2011. 

Worldwide billings declined to $609 million, down 13% from the previous quarter and 60% below the same quarter one year ago. 

While the book-to-bill ratio remained below parity for the sixth consecutive quarter, the ratio did improve to 0.38 given the flat bookings and the decline in billings.
