Big Power or Compact Maintenance? Your Ideal Victron Panel

Whether you are fitting out a 4WD for a lap of Australia, setting up a remote tiny home, or just need to keep your boat batteries topped up, the reliability of your solar setup is non-negotiable. At Voltage Electrical Supplies, we understand that when you’re off-grid, your power system isn’t just a luxury—it’s a lifeline.

That is why we proudly stock Victron Energy solar panels. Renowned globally for their "Blue Power" innovation, Victron panels offer superior build quality, exceptional low-light performance, and rugged durability suited for the harsh Australian climate.

In this guide, we’ll break down five of our top-selling Victron panels to help you choose the perfect match for your energy needs.

Monocrystalline vs Polycrystalline

Before diving into the specific wattages, it is helpful to understand the two main types of technology available in our Victron range:

• Monocrystalline (Mono): Made from a single crystal structure, these panels are typically black and offer higher efficiency. They perform slightly better in high heat and take up less space for the same power output.

• Polycrystalline (Poly): recognizable by their blue speckled look, these are made from melted crystal fragments. They are cost-effective and have a slightly lower tolerance for heat compared to mono, but Victron’s advanced engineering ensures they still perform exceptionally well.

1. 20W Panels (12V)

Perfect for: Trickle charging, gate openers, jet skis, and maintaining starter batteries.

If you have a vehicle, boat, or piece of machinery that sits idle for weeks at a time, a small solar panel is the best insurance against a dead battery.

• Victron 12V 20W Mono Solar Panel: Compact and efficient, this panel is ideal if mounting space is tight.

• Victron 12V 20W Poly Solar Panel: A robust and cost-effective solution for keeping batteries healthy without overcharging.

Why we love them: Both models come with Victron's low voltage-temperature coefficient, meaning they don't suffer as much voltage drop on hot Queensland days as cheaper generic panels might.

2. 115W Monocrystalline (12V)

Perfect for: Camper trailers, small caravans, and 4WD roof racks.

The Victron 115W 12V Mono Panel strikes a perfect balance between size and output. It is powerful enough to offset the daily consumption of a 12V fridge and LED camp lights on a sunny day.

• Shade Tolerance: Integrated high-performance bypass diodes minimize power drop caused by partial shading—essential when you are parked under gum trees.

• Durability: The sealed, waterproof junction box and anodized aluminum frame are built to withstand vibrations and rain.

3. 175W Monocrystalline (12V)

Perfect for: Extended touring, marine applications, and larger battery banks.

When you need serious replenishment for your deep cycle batteries, the Victron 12V 175W Mono Solar Panel is the go-to standard.

A single 175W panel can often support a complete 12V camping setup (fridge, lights, water pump, and phone charging) indefinitely in good weather. If you are running an inverter for laptops or camera gear, pairing two of these panels will give you a formidable power station.

4. 305W Monocrystalline (24V)

Perfect for: Tiny homes, large motorhomes, commercial vehicles, and 24V systems.

Stepping up in voltage and power, the Victron 305W 24V Mono Panel is designed for larger permanent installations.

Unlike the smaller 12V panels, this unit outputs at 24V, making it highly efficient for charging 24V battery banks or 12V banks via a quality MPPT controller (which converts the higher voltage into extra charging amps).

• High Efficiency: With 60 monocrystalline cells, this panel captures maximum energy even when the sun angle isn't perfect.

• Safety: The advanced EVA encapsulation system with a triple-layer back sheet meets stringent safety requirements for high-voltage operation.
