A commercial solar guide should start with your business’s electricity use, operating hours, roof condition, available space and network connection requirements. Compare system sizes, expected daytime generation, export limits, battery options, upfront or financed costs, and the value of reducing grid electricity purchases. Government incentives and certificates may be available, but eligibility and value depend on the system, installation date and current rules, so check energy.gov.au and obtain advice from a qualified installer. Ask for itemised proposals, realistic performance estimates, warranties and details of ongoing maintenance before choosing a provider.
