The age of solar + storage is here. It’s the least expensive option to add power to the grid today, and prices are still dropping while efficiencies are increasing.
And cables, and a rack to hold them, and a tool to crimp those big huge cables, etc.
For professional installers, they can install these pretty easily, or install the more 'integrated' systems with a much, much larger margin for faster..

2. Financing. Most likely you are driving a EV financed by a bank. They've got the process so streamlined you can know within minutes if your 4-wheeled battery bank is coming home with you or not. Trying to get a house battery financed is such a convoluted mess. If it was advertised like a dealership, "Come down to Big Al's Battery Barn. We'll set you up with a 10kWh bank with 0% financing!", I imagine these things would fly off the shelf. Leading back to 1.
Standalone batteries will be in the low $200/kwh and DIY in the low $100s.
What is striking about this is that usable Sodium Ion is just entering the market in volume. It should:
- push any and all electric-battery platforms under ICE equivalents by substantial margins, possibly 30-50% price reductions. Tools, Cars, Trucks, etc
- that will enable lithium chemistries to get cheaper, because they don't need to be used where their density isn't needed.
Sodium-Sulfur, which hopefully becomes viable in 5 years (might be dependent on commercial graphene so....), offers even more potential.
The dendrite formation and other things are of course problematic. What I think is going to happen is that solid state battery techs will be applied.
For example, I think they DO have a successfully cycling high-capacity room temp sodium sulfur chem ... they just need to use graphene.
And the joke about graphene is that it can do anything EXCEPT get out of the lab/commercialize.
