Tesla Motors (NASDAQ:TSLA) made huge waves in the market recently as it announced it plans to build the world's largest lithium-ion battery factory. While this multibillion-dollar investment will definitely have a profound impact on the Tesla's manufacturing capacity, it will also hopefully help bring down the costs of lithium-ion batteries. That reduction in costs will also have a major impact on not just Tesla, but SolarCity (NASDAQ:SCTY), which will certainly benefit, too. 

With the distributed solar space becoming a little more crowded with utility giants like Exelon (NYSE:EXC) and NRG Energy (NYSE:NRG) providing options of their own, SolarCity needs a way to differentiate itself from the rest. Find out how the move by Tesla could actually be that needed spark by tuning into the video below.
