(Reuters) - Panasonic Corp (6752.T) will invest more than 30 billion yen ($256 million) in a New York production facility of Elon Musk's Tesla Motors (TSLA.O) to make photovoltaic (PV) cells and modules, deepening a partnership of the two companies.
Tesla's shares were up 3.5 percent at $220.75 in early trading on Tuesday.
Japan's Panasonic, which has been retreating from low-margin consumer electronics to focus more on automotive components and other businesses targeting corporate clients, will make the investment in Tesla's factory in Buffalo, New York.
The U.S. electric car maker is making a long-term purchase commitment from Panasonic as part of the deal, besides providing factory buildings and infrastructure.
In a statement on Tuesday, the two companies said they plan to start production of PV modules in the summer of 2017 and increase to one gigawatt of module production by 2019.
