Solar Panels vs Home Battery: Which Investment Comes First?

Solar panels generate energy, while home batteries shift when you use it. These are different financial investments, and their value depends on your tariff and usage pattern.

Why solar often comes first

Solar can reduce your electricity imports immediately, especially if your home has meaningful daytime demand. Without storage, surplus energy earns the feed-in tariff rather than the retail import rate.

How batteries change the calculation

A battery captures some otherwise exported solar and shifts it to evening usage. The benefit is the difference between avoided electricity purchases and forgone export income, net of storage losses and equipment costs.

What to compare

Compare solar-only, solar-plus-battery and do-nothing scenarios. Include battery replacement, inverter replacement, export rates and your personal discount rate.
