Adding to the number of China-based PV manufacturers pre-announcing, JA Solar said that it would exceed module shipment guidance for the fourth quarter and full-year 2011. Shipments for the fourth quarter are expected to be in the range of 390MW to 410MW, compared to previous guidance of between 310MW to 330MW.

As a consequence, full-year shipments are expected to higher than previously guided levels of 1.6GW. JA Solar said shipments would be in the range of 1.68GW to 1.70GW.

According to Jeffries analyst, Jesse Pichel in an investor note the increased shipment guidance was put down an 80MW increase coming mostly from projects in the US and China. However, the analyst expects further margin pressure and write-downs, inline with announcements already made by key competitors.

The company doesn’t expect to release full financial results until mid- to late March.
