Strategic Optimization
Why calculate this?
Battery quotes are hard to compare because savings depend on the spread between imported power and exported solar, plus how often the battery actually cycles.
How the estimate works
The model values stored solar at the avoided grid price minus forgone export credit, multiplies by usable capacity and daily cycles, then subtracts annual maintenance or degradation cost.
Best next step
Ask each installer for usable capacity, expected cycling, warranty, degradation, backup capability, export tariff assumptions, and whether the quoted battery is being sold for ROI, resilience, or both.
