Solarbuzz estimates PV Book-to-Bill in Q4'10 remains above parity

March 10, 2011 // By Paul Buckley
A new PV Book-to-Bill analysis featured in the Solarbuzz PV Equipment Quarterly report shows the PV Book-to-Bill In Q4’10 (ending December 31, 2010) posted a three-month average of 1.10. Across the entire year, the 12-month average in 2010 reached 1.27 compared to 0.97 for 2009.

For the tier 1 segment, the PV Book-to-Bill ratio was higher at 1.39 during Q4’10, with a 12-month average of 1.26.

According to Finlay Colville, Senior Analyst at Solarbuzz, “The latest PV Book-to-Bill figures reflect the ongoing investments across both c-Si and thin-film segments, which are driving strong capacity expansions planned for 2011. Tier 1 c-Si manufacturers are expanding to reach vertically-integrated GW+ status on the back of still strong order books. Conversely, investments into a-Si/uc-Si and CIGS thin-film technologies represent the continued push by new entrants to find low-cost alternatives to First Solar’s exclusive challenge to c-Si dominance in the market today.”

Working closely with the PV equipment supply-chain, the Solarbuzz PV Book-to-Bill analysis maps out quarterly spending profiles by all PV manufacturers with the relevant bookings and revenues assigned to the appropriate process tool manufacturers.

The consolidated PV Book-to-Bill analysis yields an averaged figure based on industry-wide equipment investments across established and emerging technologies. However, tier 1 cell manufacturer trends can be a more appropriate leading indicator to assess the impact of production equipment used to meet end-market PV demand.

Colville added: “Tier 1 designated c-Si cell and thin-film panel producers satisfied 75% of PV demand during 2010. Equipment supply to this crucial midstream solar cell manufacturing segment highlights the portion of overall PV capacity expansion that is most likely to drive the level and timing of any panel oversupply during 2H’11.”

Solarbuzz says that early indications are that this segment’s Book-to-Bill ratio will dip below parity during Q2’11. This would represent the first sign of capacity expansion slowdown by leading PV producers and the beginning of a downturn in revenues on offer to leading PV equipment suppliers through 2H’11 and 1H’12.
