OSLO, Jan 12 (Reuters) - Norwegian solar equipment maker REC said on Wednesday demand for its products was strong and its key owner made clear REC shares were not for sale for now, lifting the stock to a three-month high.
Chief Executive Ole Enger added that REC still expected prices for its products to decline in 2011, but said the fall would "perhaps not be as big as previously expected".
