Integrated solar company REC Group (REC.OS) Friday said its markets have continued to weaken, so its solar production will remain below capacity into the third quarter of the year.

The Oslo-listed company also said it plans to raise NOK4.5 billion ($713,090) in equity, NOK0.5 billion more than previously stated, and has postponed the subscription period by around three weeks to between June 29 to July 13.

"As stated in the report for the first quarter 2009, the demand for solar products is currently weak due to the increased economic uncertainty and low availability of financing for new investment projects," the company said in a statement. "A lower level of solar installations has reduced the demand and prices for solar modules, which in turn has started to affect the supply and demand balances and prices further up the value chain."

REC has already reduced production and made short-term layoffs in its wafer and solar units.

The company said it will incur a NOK300 million nonrecurring hit in the second quarter relating to costs associated with repair work needed for malfunctioning junction boxes in its solar modules.

Looking forward, REC said its new integrated solar project in Singapore continues to trend toward a lower capital expenditure compared with initial investment projections due to a less heated construction market.

The company said longer-term fundamentals in the poly-voltaic industry remain "intact, with return on investments in solar systems reaching record high levels."

Economic stimulus packages, especially in the U.S., are expected to positively impact the PV market, REC said, adding that "it will take some time before the policies implemented materialize as increased demand."

At 0830 GMT, REC traded down NOK4.60 or 7% to NOK61.20, against a 1.29% gain on Oslo's OSEBX index.
