How long can it power your home?
Cali-Graf calculation
Average home load
Runtime from full
0.5 kW
≈ 110.6 h

60 kW (full continuous power)
≈ 0.9 h
Runtime = 55.3 kWh usable (datasheet) ÷ load. A typical home averages 1–2 kW; air conditioning and EV charging use much more. Inverter and wiring losses shorten it.

Solar array size that refills the battery from empty in one average day, before the home uses any of it (NLR PVWatts v8, 20° south roof).
Only installer and ZIP level is shown — no homeowner names, street addresses or permit numbers. Permits from LA County (unincorp.) come without a contractor license, so they count toward totals but not toward installers. Counts grow as more permit portals are loaded.
