FRANKFURT, Aug 8 (Reuters) - Plunging prices for solar equipment caused a bigger than expected loss at SMA Solar , putting more pressure on Germany's top sector player to escape a crisis that has rattled most parts of the industry.
A glut of cells and panels as well as tough competition from Asia has led to a pricing squeeze in the solar industry over the past four years, pushing many former heavyweights into insolvency including Q-Cells, Solon and Conergy.
SMA Solar - the world's largest maker of solar inverters, a key component needed to feed solar electricity into the power grid - was long protected from the problems as production of inverters requires deeper technological expertise than that of panels or cells.
But an influx of Asian competitors has now caused prices for inverters to plunge, narrowing SMA Solar's operating margin to 7 percent last year from about 27 percent in 2010.
The company slumped to a loss before interest and tax (EBIT) of 14.8 million euros ($19.7 million) in the second quarter from a profit of 40.8 million a year earlier.
The loss was wider than the 5.6 million euros average forecast in a Reuters poll of banks and brokerages. Its net loss reached 10 million euros in the quarter, wider than the 3.3 million average forecast.
"Overall, SMA Solar reported a weak set of Q2 results on the back of continued tough market circumstances in Europe, increased competition, a shift in geographical demand, which has all led to significant price pressure," said Serena Zuidema, analyst at Dutch bank Kempen & Co.
Shares fell as much as 6.7 percent in early trade but traded up 1.6 percent at 0855 GMT, as traders said it was unlikely the group would follow the same fate as panel-making peers such as SolarWorld, which late on Wednesday struck a deal with shareholders about a wide-ranging restructuring.
The global solar inverter market is forecast to shrink 5 percent to $6.7 billion this year, according to research firm IHS, while the European market, where governments are scaling back solar power subsidies, will contract to 32 percent of inverter shipments, from 82 percent in 2010.
"The slump in demand in Europe forces additional cost-cutting measures and an adjustment to the personnel structures," SMA Solar Chief Executive Pierre-Pascal Urbon said.
Last month, the group said it would cut about 14 percent of its 5,800 staff in an attempt to lower costs and improve margins.
SMA Solar kept its outlook for the current year for sales to reach between 0.9 and 1.3 billion euros, while confirming it cannot rule out a loss.
