Solar & Battery Reality Check | Chasing Utah

Chasing Utah / The useful tool

See how the energy adds up.

Explore two simple questions: how much energy a hypothetical solar array could produce, and how long a battery could support a constant load.

Adjust the sample values below. This isn't a savings quote, a site assessment or an emergency-power design. No account or private address needed.

1. Solar production

2. Battery duration

Modeled annual solar energy

10,512 kWh/yr

8 × 4.5 × 365 × 0.8. Seasonal output will vary.

Modeled battery runtime

22.9 hours

13.5 × 0.85 × 1,000 ÷ 500. Does not verify peak power or surge capability.

What the model doesn't know.

Solar output varies with location, weather, roof conditions, shading and equipment. Backup runtime assumes a constant load; actual systems have inverter power limits, startup surges, usable-capacity limits and additional losses. Savings, financing, local incentives and system suitability require a qualified assessment. Don't use this as an electrical design or emergency plan.
