Tesla Powerwall payback in Australia

What changes the payback period?

Powerwall payback depends on installed cost, usable battery capacity, household evening usage, electricity tariff, feed-in tariff, backup needs and any available battery discount. A lower quote or stronger evening usage can shorten payback; low night usage or cheap grid rates can extend it.

What to ask before buying

• What installed price is quoted after any eligible discount?
• What assumptions are used for bill savings?
• Does the quote include backup hardware and monitoring?
• How are warranty and workmanship handled?
