Start by reviewing at least 12 months of electricity bills to understand when your business uses power, as matching solar generation with daytime demand can improve the project’s value. Check the roof’s condition, available space, structural capacity and any export limits with a qualified installer, and compare system designs rather than focusing only on panel size. Ask about monitoring, maintenance, warranties, insurance and whether a battery could help manage demand or use more solar after hours. A licensed installer and your accountant can also explain approvals, financing, tax treatment and possible incentives, which depend on your circumstances and current rules.
