💰 How are prices calculated?

We like to keep things simple and transparent, so you always know what you’re paying for — and what you’re saving.

Total Price = Battery Price – Federal Battery Rebate

All eligible battery systems receive a federal rebate based on usable capacity. The rebate is currently calculated as:

$350 × Usable kWh of the battery

For example, let’s say you’re looking at a battery system with 15 kWh usable capacity. The rebate would be:

$350 × 66.5kWh = $23,275.00 federal rebate

So if the system’s full retail price is $55,550 , the displayed price on our website would be:

$55,550.00 – $23,275.00 = $32,275.00

This is the amount you’d typically pay (incl. GST) for standard installation. 

✅ No paperwork is needed — we apply the rebate upfront and handle the claim process for you.
