This page is an appendix to our recent article: “Is home solar battery storage worth it in 2017?”
The infographic gallery below provides snapshots of total system cost, payback periods, return on investment and other key performance indicators for a 5kW solar system plus Alpha-ESS Storion Eco in each Australian capital city.
Two scenarios have been modelled for each city: one for customers on a flat or block retail electricity tariff, and a second for customers on a time of use (TOU) tariff.
Please note that all results are indicative only.
All infographics were created using SunWiz’s PVSell software.
Adelaide, SA
Brisbane, QLD
Canberra, ACT
Darwin, NT
Darwin residents are eligible for a solar feed-in rate equal to their retail electricity rate, which means that batteries will only reduce potential savings when installed alongside a grid-connected solar system. Therefore we have not included results for Darwin in this analysis. If you’d like to estimate payback periods for grid-connected solar systems (without batteries) in Darwin, check out our Solar System Payback Estimator Tool.
Hobart, TAS
Melbourne, VIC
Perth, WA
Sydney, NSW
