Commercial solar design should start with how a business uses electricity, not simply the maximum number of panels that fit on the roof. A well-matched system can offset some grid purchases during operating hours, but the result depends on the site's load profile, tariff and network conditions.
Review interval data and operating hours
Half-hourly or interval consumption data helps identify when the site uses electricity. Compare weekday, weekend and seasonal patterns with expected solar generation. Businesses with strong daytime loads may be able to use more solar directly.
Assess roof and electrical capacity
Roof structure, orientation, shading, access, switchboard capacity, transformer limits and export restrictions can affect system size and project cost. Larger projects may need engineering and network studies before a final design is confirmed.
Understand the financial assumptions
Ask for estimated generation, self-consumption, exports, tariff assumptions, maintenance considerations and any demand-charge effects to be explained. Savings should be based on the site's actual retailer rates and operating profile.
Consider battery storage carefully
A commercial battery may help shift solar energy or manage demand, but it adds capital cost and system complexity. Compare the battery's usable capacity and power output with the business load and operating strategy.
Plan the project and handover
Discuss installation staging, site access, safety management, shutdown requirements, monitoring and ongoing support. The proposal should set out responsibilities and any exclusions clearly.
