There is a branch of battery research that is only focused on grid storage. It’s the last piece to make solar and to a less extent wind unbeatably affordable.
In a home solar setup, batteries are the other half of the cost and have not fallen as fast as the cost of the panels themselves, the other half of the cost. For fully off grid setups, they quickly become the main cost.





Nah, need to go straight to 9, 3x3 matrix. It’s acceptable to pause at 6 if you are budget conscious.
