The research analysts say that while photovoltaic manufacturers believed module shipments would increase 12 percent from the first to the second quarter of 2011, they actually declined by 22 percent.
And, despite the fact demand was said to have risen by 79 percent and production fell by around 20 percent quarter on quarter, Solarbuzz says both cell and module inventories increased by 559 megawatts.
Consequently, inventories are expected to hit 8.6 gigawatts (GW) by the end of the second quarter. In particular, upstream inventories are expected to show a "sharp" increase, while downstream will see a "small" decrease.
"Recent price reductions from Tier 2 Asian manufacturers will place enormous pressure on others to follow suit," explains Craig Stevens, Solarbuzz president. "Even with significant cutbacks in production and shipments, Q411, factory-gate module prices are still projected to fall 25 percent Y/Y."
This market pressure is expected to make the second half of the year challenging, says Solarbuzz, with expectations that the end market will grow just five percent from 2010.
In a statement, the company explains: "The revised global PV market size of 19.3 GW for 2010 is now projected to increase to just 20.3 GW in 2011." IMS Research, on the other hand, believes that over 23 GW will be reached this year.
It is believed that lower module prices will now drive demand upwards in the second half of the year.
"However, chances for that depend on downstream inventories falling fast and on resolving the policy uncertainties in Europe that have characterized 1H11. Rather than further procurement, most downstream companies are currently focused on reducing inventories in order to avoid write-offs emanating from the collapse in prices," continues the statement.
Just last week, IMS Research stated that it believes the photovoltaic industry can look forward to a strong rest of the year in terms of shipments, again due to the much lower prices. The fact that Germany did not lower its feed-in tariffs on July 1 is also thought to be a positive market driver.
"Module prices have fallen incredibly quickly in the first half of 2011," commented photovoltaic market analyst Sam Wilkinson. He added: "Considerable reductions in price combined with no mid-year feed-in tariff reduction in Germany, will make investment in photovoltaics attractive again."
