350W Half Cut PERC Mono PV Solar Panel

Serious off-grid power for your motorhome, caravan or bus conversion

When you’re parked up at a remote DOC campsite or freedom camping far from a power point, your solar setup is what keeps the fridge cold, the lights on and the devices charged. The 350W TOPCon Half-Cut Solar Panel delivers genuine, dependable charging power in a slim, roof-friendly format built for life on the road.

At just 17.4kg and a low 30mm profile, this panel is light enough for most RV roofs and slim enough to keep wind drag and visual bulk to a minimum. With 20.08% module efficiency, you get more watts per square metre of precious roof space – ideal when every centimetre counts.

Why TOPCon technology matters for RV owners

TOPCon (Tunnel Oxide Passivated Contact) is the next step up from the standard PERC panels found on most motorhomes. The cell design loses less energy internally, which means better real-world output – especially in the lower light conditions you strike on overcast New Zealand days, early mornings and late afternoons. More usable charge going into your batteries, more often.

Half-cut cells: built for the way RVs actually park

Unlike a house, your RV rarely sits in perfect, uninterrupted sun. Trees, aerials, air conditioning units and neighbouring vehicles all cast shadows across your roof. Half-cut cell panels are split into two independently operating halves – so if one section of the panel is shaded, the other keeps producing at full strength. The design also reduces internal resistance and mechanical stress, giving you a tougher, longer-lasting panel that handles the vibration and flex of travel.

Key features

• 350W peak output – enough to run a serious 12V house battery or lithium setup
• 20.08% module efficiency – maximum power from limited roof space
• Half-cut cell design – superior shade tolerance and durability on the move
• TOPCon cell technology – improved low-light and real-world performance over PERC
• Slim 30mm anodised aluminium frame – low profile, corrosion-resistant, travel-tough
  3.2mm tempered safety glass – built to handle hail, branches and gravel roads
• IP65-rated junction box with 90cm 4mm² cables and MC4 connectors – ready to wire straight into your system
• Lightweight at 17.4kg – easier installation and less load on your roof

Warranty you can rely on

This is a tier-one panel backed by outstanding manufacturer warranties, so you can invest with confidence:

• 25-year performance warranty – guaranteed to 80% of rated output
• 10-year performance warranty – guaranteed to 90% of rated output
• 5-year warranty against production and material defects

That’s a quarter of a century of guaranteed performance – likely longer than you’ll own the vehicle it’s mounted on.

Sized right for RV installation

At 1980 x 880 x 30mm, this panel suits larger motorhomes, buses and caravans with the roof space to take advantage of a single high-output panel rather than juggling multiple smaller units – meaning fewer mounting points, fewer cable entries and a cleaner install.
