Panasonic to make Sanyo, other unit wholly-owned-sources

TOKYO, July 29 (Reuters) - Panasonic Corp (6752.T) plans to acquire the shares it does not already own in Sanyo Electric Co 6764.T and Panasonic Electric Works Co Ltd 6991.T, four sources with knowledge of the matter said.

Panasonic currently owns 50 percent in Sanyo, a maker of solar cells and rechargeable batteries, and 51 percent of Panasonic Electric Works, a maker of housing materials and lighting equipment.

Based on current market prices, acquiring the shares it does not own would cost Panasonic about 720 billion yen ($8.23 billion). Placing a typical premium could lift the value of the deal to around 900 billion yen.

Panasonic could make an offical announcement of its plans this week, the sources said, speaking on condition of anonymity. (Additional reporting by Reiji Murai; editing by Elaine Hardcastle)
