It usually stacks up where the business runs solid daytime loads and the lease has several years left to run, since savings accrue over years of trading. It is harder to justify on a short remaining lease, a tenancy that mostly operates after hours, or a roof needing major work before panels can go on. The sensible step is to size the system to your measured daytime use and weigh the saving against your remaining lease and any roof repairs.
Cost depends on system size, your daytime energy use, roof type and condition, switchboard upgrades and whether Western Power requires a network application. Older Wangara units sometimes need mounting or electrical work that larger modern warehouses do not. We assess all of this on site, then provide a written quote tailored to your premises rather than a one-size figure.
Many do, but we check the sheeting and structure first. Some older industrial roofs in the estate have aged metal or limited fixing points that need attention before panels go on. If remedial work is sensible, we flag it early rather than later, so the solar system sits on a roof that will comfortably carry it for its full working life.
