Camera solar

Estimate solar size for security cameras.

Use camera energy, backup days, usable battery capacity, output efficiency, and sun conditions to estimate a nameplate battery and panel target.

Quick resultRun estimate

Always-on cameras need battery headroom for cloudy days, discharge limits, and output losses.

Planning assumptions

Watts per cameraUse measured draw if possible.Camera countNumber of cameras on this solar setup.Hours per dayMost security cameras are planned as always-on.Backup daysBattery reserve for cloudy weather.Battery voltageCommon small-system voltage.Usable battery capacity percentThe share of nameplate capacity available after reserve and discharge limits.Battery-to-camera efficiency percentLoss through regulators, converters, PoE hardware, or other output equipment.Good sun hoursUsable strong sun at the panel location.Panel-to-battery efficiency percentSolar collection and charging loss; small panels lose output quickly with shade and poor angle.

Use this as a planning estimate

Small solar and backup-power estimates depend on real device draw, temperature, battery age, sun, shade, and product limits. Use the result to narrow a shopping range, then verify exact specs before buying.

Planning notes

What this calculator is checking

Always-on

Small watts become big daily Wh

A 6W camera running 24 hours uses 144Wh at the camera; battery output loss and usable-capacity limits increase the nameplate target.

Shade

Camera locations are often bad solar locations

Eaves, trees, and walls can make a tiny setup unreliable.
