Updated: 2026-10-31

Free planning aid for UK off-grid CCTV deployments. It estimates energy-service visits and battery behaviour for a defined site, season, load and power configuration.

Inputs:
- UK site postcode
- deployment start month and duration
- continuous electrical load in watts
- 24 V battery capacity (200, 400, 600, 800 or 1000 Ah planning options)
- solar array capacity
- optional fuel-cell reserve with one fitted bottle; replacement visits may be needed

Outputs:
- estimated energy-service visits
- first intervention
- longest unattended interval
- minimum modelled battery state of charge
- daily or weekly battery/solar timeline
- recharge and fuel-reserve service markers
- comparison of standard battery and solar combinations

Solar model: PVGIS
Timeline: Hourly historical PV reference sequence (currently 2023) used as planning data, not a future weather forecast.
Boundary: No result is a runtime guarantee. Final equipment, installation conditions and operating assumptions require engineering review and written quotation.
