1. Your usage

Put in a rough daily energy target. You can also use this as a simple “backup only” sizing tool.

These are just rough planning targets. Later we can auto-fill these from a project you’ve already modeled on the Roof Planner.

2. Suggested system

We convert your usage target into a ballpark array size, battery size, and inverter rating.

Solar array (kW)
Battery bank (kWh)
Inverter rating (kW)

Notes

  • Array size assumes ~4.5 peak-sun-hours/day and 85% overall system efficiency.
  • Battery size is set to 50% of your daily usage × autonomy days.
  • Inverter rating is sized to handle ~70–100% of your peak load, depending on mode.
