Solar savings are site-specific The same 3 kW system can save different amounts for different homes. Savings depend on your electricity tariff, daytime usage, exported units, system generation, subsidy, finance cost, and maintenance. Self-consumption matters Solar units used directly by your home or business generally create strong value because they reduce purchased electricity. Exported units depend on applicable rules and billing treatment. That is why system sizing should follow usage, not only roof area. Residential example thinking For a home, compare monthly units, roof size, subsidy eligibility, and expected generation. An on-grid system often gives the best return when backup is not required. If you need backup, compare the extra cost of battery backup. Commercial savings Businesses with daytime load can often use more solar generation directly. A commercial proposal should include load profile, generation estimate, maintenance scope, and payback assumptions. See commercial solar for details.
