What is the true cost to you behind energy storage?

Thus, the LCOE is $0.095 cents per kWh. This is lower than the national residential average electricity rate of $0.12/kWh. In addition, such a battery will deliver 34 MWh over its useful warranted life by the time it reaches its EOL of 80%, likely with many more years at a reduced capacity beyond the EOL 80%. Step two: Factor in ancillary costs.

Calculating Solar Home Battery Returns on Investment | sonnen

FITs are paid by energy retailers to households for any unused electricity generated from their solar system that is sent back to the grid.
