Estimate your payback period with live incentive pricing. Adjust your state, system size, electricity rate, and install cost to see real-time results.
Estimate only. Uses a typical production yield for your state, the certificate prices shown by the incentive hub, and a single electricity rate; demand charges and time-of-use windows are not modelled.
Payback is the net cost of the system after incentives divided by what it saves you each year. For commercial solar the savings come from three places: the grid power you avoid buying by using solar on site, credits for any surplus you export, and, on a demand tariff, a lower peak charge when solar trims your midday draw.
Self-consumption is the big lever. A business that runs most of its load in daylight — a factory, a cold store, a busy office — uses more of what the panels make and pays the system back faster than a site that only gets going after dark. Your tariff, your time-of-use rates, and how much usable roof you can fill all feed in as well.
Most commercial systems in Australia land somewhere between three to seven years, after which the power is close to free for the remaining twenty-plus year life of the panels. Rather than lean on a national average, the calculator above uses your own state, tariff, and system size to estimate a figure for your site.
Businesses get a free estimate for their site. Solar companies get Amperage: every size, payback, and a branded proposal.
