Solar Camera Battery Runtime Calculator
The question dealers hear most: "will it still work after a week of rain?" This tool runs the energy balance — how much the battery stores, how much a day of use consumes, how much the panel puts back — and gives the number of fully sunless days the camera can ride out.
Defaults are reference assumptions, not the specification of a particular model. Drag the sliders or type values to match your situation.

The panel covers consumption even in the low-sun month you entered; the battery only has to bridge fully sunless stretches.
Estimate from editable assumptions; not a warranted specification.
How it works
- 1Stored energy = mAh × 3.7 V, times the usable share (default 80%, because the protection circuit never lets the cell run flat).
- 2Daily consumption = standby power × 24 h + active power × (triggers × seconds per clip + live-view minutes). AOV continuous recording has a higher standby draw than motion-only recording.
- 3Daily charge = panel watts × peak sun hours × system efficiency (default 70%: tilt, heat, dust, charge circuit).
- 4Sunless days = usable storage ÷ daily consumption. Rainy-season balance = charge − consumption at the sun hours you enter.
