Dive Insight:

Elon Musk, Tesla's CEO, isn't just interested in electric cars. He's on the SolarCity board and has a strong interest in linking solar with storage, which could be a game changer by making solar generation more flexible. But the batteries could be used for other energy storage purposes as well.
