Generate more power from every day in the sun with the ATG 305W Fixed Bifacial Solar Panel. Designed for caravans, motorhomes, 4WDs, boats and off-grid installations, this premium monocrystalline panel uses bifacial technology to capture direct sunlight from the front while also utilising reflected light from the rear for improved energy production. Built with a durable aluminium frame and tempered glass construction, it's engineered for reliable performance in Australia's demanding conditions

High Output Solar for Serious Off-Grid Power

If your electrical system includes larger lithium batteries, inverters, Starlink, fridges or multiple accessories, you'll benefit from the additional charging capacity of a 305W solar panel.

The ATG 305W Fixed Bifacial Solar Panel delivers dependable daily charging for:

✔ Caravans

✔ Motorhomes

✔ 4WD canopy systems

✔ Camper trailers

✔ Boats

✔ Tiny homes

✔ Off-grid cabins

✔ Remote sheds

✔ Battery storage systems

Get More from Bifacial Technology

Unlike conventional solar panels, bifacial panels collect energy from both the front and reflected light reaching the rear of the panel.

Benefits include:

✔ Higher energy production

✔ Better low-light performance

✔ Improved efficiency in reflective environments

✔ Excellent long-term value

✔ Modern high-performance solar technology

The additional energy gain depends on installation height, mounting method and the reflectivity of the surface beneath the panel. Research shows bifacial panels can outperform comparable monofacial panels under suitable conditions.

What is a bifacial solar panel?

A bifacial solar panel generates electricity from both the front of the panel and reflected light reaching the rear, helping increase overall energy production when installed in suitable conditions.

Is a 305W panel suitable for lithium batteries?

Yes. When connected through a compatible MPPT solar charge controller, the panel is ideal for charging lithium, AGM and lead-acid battery systems.

Can this panel be permanently mounted?

Yes. It's designed for fixed installation on caravans, motorhomes, camper trailers, boats, sheds and off-grid buildings.

Do I need a solar controller?

Yes. A compatible MPPT or PWM solar charge controller should always be installed between the solar panel and your battery unless your system already includes one.

Is 305W enough for off-grid camping?

For many travellers, a 305W panel provides ample charging capacity for fridges, lighting, Starlink, device charging and other common 12V accessories, depending on battery size, weather conditions and daily power consumption.
