How does a battery payback calculator work?

The calculator lets you add a battery to your solar system and will show you the marginal battery payback. It's a fancy way of saying the calculator shows you the solar and battery savings and payback separately instead of blending the payback together. Learn more about blended battery payback.

How do you calculate the payback period for solar power?

Here's a simple way to calculate the payback period for solar power. Take the total system cost and divide it by the estimated annual savings on electricity costs. To calculate annual savings, subtract the new average electric bill from the average of the old bill and multiply it by 12 months. Example: Say a solar power setup costs $10,000 all up.

How much does a solar battery cost?

How do I get a price estimate for a solar system?

How do I choose a solar battery?

If you are considering a solar battery and know what model you want, choose that from the calculator list. If you are unsure what you want, then select 'Generic 10kWh' to get an idea of typical battery savings. The calculator estimates the current price based on the selected model; but feel free to change the cost if you have a good deal.

Can a solar battery save you money?

You save money with a battery by storing your excess solar during the day instead of exporting it to the grid. Then, as the sun goes down, your stored solar energy gets used to power your house instead of grid electricity. For each kWh of stored solar you use, you’re saving what you would have spent on your usage tariff: around 30c per kWh.
