Sizing the Panel and Battery
The battery has to carry the fence through the night and through several cloudy days. The panel has to recharge it on short winter days. Installers size both from the energiser's power draw, the length of fence and whether a siren or alarm output is used.
- Energiser draw. Bigger energisers and higher power settings need a larger panel and battery.
- Alarm and siren. Security features add load. Include them in the sizing.
- Winter days. Plan for several overcast days in a row between May and August.
- Battery type. Deep-cycle or lithium batteries last longer than standard alarm batteries.
Installers will size the kit if you give them the fence length and energiser.

Where Solar Makes Sense
- Smallholdings, paddocks and farm camps with no power at the fence line.
- Remote gates and boundaries a long way from the house.
- Construction sites and temporary fences.
- Horse and livestock fencing that moves between camps.
- Security fences on sites with unreliable mains.
Cape Town Solar Considerations
- Short winter days. Size for winter, when fronts bring several dull days in a row.
- Panel angle. Panels should face north and be tilted steeper for winter sun.
- Shade. Trees, mountains and buildings can shade the panel for part of the day.
- Theft. Mount panels high or in a secure bracket. Exposed panels on remote boundaries get stolen.
- Salt and dust. Clean the panel regularly near the coast and on dusty farm roads.

Solar Electric Fencing Questions
Will a solar electric fence work in a Cape Town winter?
Yes, if the panel and battery are sized for short, cloudy days. Undersized kits are the usual reason solar fences go flat in winter.
Can a security fence run on solar?
Yes. A security energiser can run from a battery charged by solar, but the battery and panel must cover the alarm and siren load too.
Can I add solar to my existing electric fence?
Often. A panel and regulator can charge the energiser battery. An installer will check the energiser and battery first.
How long does a solar fence battery last?
Commonly two to five years depending on type and how deeply it is discharged. Lithium usually lasts longer.
Does a solar electric fence need a COC?
An electric security fence generally does, however it is powered. Confirm requirements with a registered installer.
