Frequently Asked Questions about 26.6kW Solar Systems
Does a 26.6kW commercial solar system qualify for tax benefits?
Yes — commercial solar qualifies for instant asset write-off (subject to current ATO rules) plus Small-scale Technology Certificates (STCs) up to 100kW. Vista provides all documentation for your accountant.
What’s the payback on commercial solar in Perth?
Typical payback is 4-6 years for businesses with strong daytime electricity loads. Perth’s high commercial tariffs (~$0.30-0.40/kWh) and 5+ peak sun hours produce ROI well above east coast averages.
Do I need council approval for commercial solar?
Most commercial installs in Perth don’t require council approval — Vista handles all Western Power applications and structural engineering certifications. Some heritage zones or specific local government areas may require additional sign-off.
