Solar Electric Fence Energisers — Buying Guide

Why Choose a Solar Energiser?

Solar energisers are the ideal solution for remote locations where running mains power to the fence is impractical or cost-prohibitive. Modern solar energiser technology provides reliable, consistent performance year-round in Australia’s generally sunny climate, with built-in solar panels and batteries that maintain charge even during cloudy periods. They eliminate the ongoing cost of battery replacement and reduce the need for regular site visits to swap out depleted batteries.

How Solar Energisers Work

Solar energisers incorporate a small photovoltaic (PV) solar panel, a rechargeable battery and the energiser electronics in a single integrated unit. The solar panel continuously charges the internal battery during daylight hours, while the battery powers the energiser overnight and during low-light periods. Modern solar energisers include intelligent charge management systems that maximise battery life and maintain consistent energiser performance through extended overcast periods.

Selecting the Right Solar Energiser

• Output (joules) — select an energiser with sufficient output for your fence length and the animals being controlled; higher joule ratings for longer fences and larger/more resistant animals
• Solar panel size — larger solar panels provide more charge capacity and better performance in partial shade or overcast conditions
• Battery capacity — larger battery capacity extends the number of days the energiser can operate without sunlight
• Location — consider the solar resource in your region; tropical northern Australia has excellent year-round solar; southern states may have reduced winter performance

Frequently Asked Questions

Can a solar energiser work in cloudy weather?
Yes — solar energisers include a battery that stores energy from sunny periods. A well-designed solar energiser should operate effectively for 2–5 days without sun in most Australian conditions. Extended periods of very cloudy weather may reduce performance.

How do I mount a solar energiser?
Most solar energisers can be mounted directly on a star picket or fence post using included hardware. Position the solar panel facing north in Australia for maximum sun exposure, and ensure the panel is not shaded by trees, buildings or other obstructions.

What output do I need for sheep?
For sheep in normal conditions, a solar energiser with 0.5–1.5 joules output is typically adequate for fences up to 5–10km. Longer fences, wet conditions or heavy vegetation contact require higher output units.
