ROI & Payback
Solar is a capital investment. Understand the payback, the levers that drive it, and the return for your business.
Commercial solar is best understood as an investment with a measurable return, not just an energy decision. In NSW in 2026, well-designed systems commonly pay back in three to five years and then generate largely free power for decades.
The biggest lever on ROI is self-consumption — every kilowatt-hour you use on site is worth far more than one exported. Incentives and tax treatment then improve the after-tax return further.
For a system matched to a real daytime load, three to five years is common in 2026, after which generation is largely free for the system's 25-year-plus life.
We model your load, tariff, self-consumption, system cost and incentives to estimate annual savings, payback and return — specific to your site.
Yes. STCs/LGCs reduce net cost, and depreciation or write-off provisions can improve early cash flow. Confirm tax treatment with your accountant.
