Should You Get Solar & Battery?
Whether you already have solar or are starting from scratch, see how much you could save with the right setup. Solar generates cheap power — a battery makes sure you actually use it.
- Performance ratio: 75% — accounts for inverter losses, wiring, dust, shading
- Daytime self-use: 40% of your daily usage happens during solar hours
- Peak sun hours: calculated monthly (2.4 h Jun – 6.2 h Dec/Jan) then averaged for year-round accuracy
- Battery cycling: one full cycle per day, capped at actual evening usage
- ACT loan: $15,000 max, 3% p.a., 10-year term (Sustainable Household Scheme). Requires ULV under $750,000
- Degradation: not modelled — real savings decrease ~0.5%/yr
