Even though installations of photovoltaic solar systems will rise in 2010, a sharp drop in solar components prices will lead to intense competition, as per iSuppli Corp.

"Global installed watts for PV systems will grow by 64 per cent in 2010, reaching 8.3GW," said Henning Wicht, senior director and principal analyst for photovoltaic systems at iSuppli Corp. "This will bring a return to the growth levels seen before the fall of 2008 as the worldwide recession recedes and as new geographies and segments of demand emerge."

Despite the projected return in demand for this year, the tremendous price erosion that occurred in 2009 continues to squeeze profits. On average, crystalline module prices last year fell by 37.8 per cent, solar wafer prices plunged by 50 per cent and polysilicon prices crashed by a gut wrenching 80 per cent.

This trend will continue in 2010, although at a slower rate. Crystalline module prices will drop by 20 per cent, wafer prices will decline by 18.2 per cent and polysilicon prices will fall by 56.3 per cent.

"The erosion in pricing is bound to change the face of the industry," Wicht said. "The freefall of PV prices represents a permanent ratcheting down of price structures that will transform the industry into a more competitive marketplace."

Given the enormous downward shift in pricing, one major implication for the industry is that suppliers will need to continue accelerating cost reductions in order to keep up with the price declines and to repair compressed profit margins. When the cost-down programmes eventually catch up with the rate of price declines, an overall improvement in the profit picture can be expected, Wicht said.

After suffering losses during much of 2009, PV profits will continue to improve in 2010, following a move into the positive during last year's Q4. iSuppli also is projecting that prices on average will pop back by more than 10 per cent in the final quarter of 2010, despite declines for the entire year.

The growth of PV installations in 2010 will be led by a newly energised German market, which recovered from sluggish performance in the first half of 2009 to achieve gradual growth in the second half—a trend expected to continue for the first six months of this year.

The German market, however, could stall again by summertime, if the feed-in-tariffs designed to encourage the adoption of PV systems is trimmed by the Merkel government. The position in the overall PV market held by Germany—which accounted for 50 per cent of total worldwide PV installations in 2009—is of such importance that the collective PV demand accruing from other countries will not be sufficient to compensate for a German FIT reduction of 15 per cent if that were imposed in mid-2010.

Elsewhere, installations will continue to rise in both the established and the emerging regions, according to iSuppli.

"Several new growth markets will come into play in 2010, the most significant of which are the United States, Italy and latecomer China," Wicht said. "Together, these three markets will account for 50 per cent of the growth projected to occur in 2010."

The PV space will also feature more players this year, led by South Korea's Samsung and LG Electronics—already the world's largest LCD panel makers and possessing vast experience at moving into new areas of operation—as well as Taiwan's TSMC foundry and U.S. engineering giant Bechtel.
