A good commercial solar guide should cover your business’s electricity use, daytime load profile, roof or ground-mount options, system sizing and any grid export limits. Compare buying the system with finance or a power purchase agreement, and consider batteries if reducing demand charges or evening usage matters. Potential incentives, such as certificates under Australia’s renewable energy schemes, depend on system details and current rules, so confirm eligibility through the official government information and your installer. Use an appropriately licensed, experienced installer and check connection approvals, warranties, monitoring, maintenance, insurance and tax advice before signing a contract.
