Off-grid electricity from your home’s solar panels is the future.
Globally, the market for solar PV panels and battery storage is expected to grow tenfold in less than five years.
Lithium battery demand will explode over the next decade with EVs and home storage of solar electricity.
I have written articles describing the rise of solar energy and electric vehicles on Seeking Alpha in 2015, which you can read here and here. With the meteoric rise of Solar and EVs the final stage to be energy self sufficient will be energy storage most likely using lithium batteries.
