This is a very subjective post. I was always very keen to know what Tesla Powerwall was, and never actually bothered to read or wiki or youtube about it. Musk made it equals ‘is cool’ means ‘heap’ stands for ‘someday maybe’ really deciphers into ‘not in this part of the world unless one is fabulously well off.’ Summoning my excited pessimism, I have rolled my sleeves up and typed ‘power wall’ in the search bar. Four days later I made it to my laptop again to see ten or twelve tabs all reading tesla power w… A weekend has passed and I made myself find time to read, watch and comprehend.
Then I sketched what I got from all of this (attached).
A) The Sun is needed and conventional grid works well too.
B) PV panels are required too to send DC current to a sleek looking like a model S P85D bonnet cabinet
C) Powerwall either stores or uses electricity.
D) Energy bill is affected: use an off-grid electricity supply from your very own Powerball during peak hours
Internet is a good source till comments start coming along. One is not enough some say. 3.3kW limits the number of appliances used simultaneously. You need to put several batteries together to get a decent household use, they add.
Hey, we might have forgotten: the first iPhone did not record videos too.
The first battery of the kind might be expensive and till date may not be the most practical yet it gives a chance to store your own energy. A user stops just buying a kilowatt that is instantaneously consumed. A user can keep her kilowatt, and if not used, sell it or exchange. This is an economy.
