To store one day of energy, you'll need around 6 to 8 lithium batteries (13. 5 kWh each) for a 20kW solar system, depending on your actual usage. . Battery sizing is goal-driven: Emergency backup requires 10-20 kWh, bill optimization needs 20-40 kWh, while energy independence demands 50+ kWh. Your primary use case should drive capacity decisions, not maximum theoretical needs. Here is how to estimate. . Let that sink in: Every kilowatt-hour you don't store costs you up to $0. Smart homeowners aren't playing that game. First: What Are You Really Powering? Before we talk numbers, let's define your priorities.
