Panasonic already owns 54.18 percent in PanaHome and it offers to pay 1,200 yen per share to acquire the rest of the shares, it said in a statement.
The offer represents a 16.4 percent premium to Friday's closing price.
Panasonic said last year it had agreed to buy out its subsidiary through an all-stock deal.
