REC produces silicon materials for photovoltaics (PV) applications and multicrystalline wafers, as well as solar cells and modules.

[11] The development of this site was projected to enable REC’s ability to deliver solar products that can compete with traditional energy sources in the sunny areas of the world without government incentives.

In August 2008 REC made the decision to build a new facility for silicon manufacturing expansion in Bécancour, Quebec, Canada.

The large drop in value has been partially blamed on the financial crisis,[14] which caused a near halving of the price of silicon wafers, as well as increasing costs of investments, in particular due to delays in opening a new factory in Moses Lake, Washington.

[18] All of REC's solar cell and wafer production plants in Norway were shut down permanently in 2011 and 2012 due to weak market conditions and prospects of significant negative cash flow.

[20] The splinter company consisted of the silicon manufacturing facilities at Moses Lake, Washington and Butte, Montana and is based in the United States.
