US electric carmaker Tesla Motors is planning to make a big investment in charging infrastructure throughout Japan.

Elon Musk, CEO of the company told the Nikkei in an interview that all the charging stations will be either directly or indirectly solar powered.

He said, "We'll buy utility power that's coming from solar panels, or we'll have solar panels on the charge station itself. There will be no impact to the electrical grid in Japan".

The much highly anticipated Tesla announcement scheduled for Thursday night raised the company's shares by 7%.

So far, very little details as to what Tesla CEO Elon Musk will announce are known to people, but still there are major clues available.

Tesla Motors owner last month buzzed the internet through a tweet in which he said that his company's new move would be a new product line and not a car.

All the clues indicate towards what the company calls, Stationary Energy Storage Applications. In simpler terms, they're consumer batteries that would power homes and businesses.

These batteries will be available at a very suitable price and could slash electric bills by nearly 25%. Tesla's $5 billion gigafactory outside of Reno could play a big role in producing the innovative batteries.

As per the latest projection given by the company, the gigafcatory will produce battery packs for their automobiles. As much as a quarter of the plants energy will be used for the stationary batteries, it said.

During the company's last quarterly earnings call in February, Elon Musk indicated that his company will very soon unveil a home consumer battery.

Also, Tesla in its latest shareholder report projected that it would start increasing in sales of stationary batteries in 2015.
