Enter your typical load and expected use days to compare a solar power station against a gas generator on cost and convenience.
This compares pure cost only — solar stations run silently with no fumes and need sun to recharge, while gas generators run regardless of weather but need fuel storage and ventilation.
A gas generator is cheaper upfront and can run indefinitely with refueling regardless of weather, while a solar power station has no recurring fuel cost but is limited by its battery capacity and sunlight for recharging — making it better suited to lighter loads over multiple days rather than heavy continuous draw. For higher loads or extended outages, check the home battery vs generator calculator for the whole-house version of this comparison.
Most portable solar power stations are sized for essentials — lights, phones, a small fridge, medical devices — not a whole home's demand, which typically requires either a much larger battery system or a generator.
It depends on panel size and sun availability — a well-matched solar panel can meaningfully extend runtime during a multi-day outage, but cloudy weather or an undersized panel limits how much you can rely on solar recharge alone.
