One of the main economic factors that prevents solar energy from being a good supplement to grid supplied electricity is our inability to store electricity.  For the most part, we’ve been forced to use solar as it’s being produced which limits how we can use it.

This is beginning to change as seen by the introduction of the Tesla “Power Wall”, a home battery that is designed specifically for storing solar energy.

This is good news and the financial and engineering requirements needed to design and manufacturer the Power Wall show how committed Tesla is to alternative energy sources!
