250W Shade Resistant N-Type TOPCon Solar Panel | 1715 x 670mm

☀️ EXOTRONIC 250W FUSION FIXED SOLAR PANEL – SHADE RESISTANT

250W • N-Type TOPCon • Triple Shade Resistance • 25.2% Cell Efficiency • 1715 × 670 × 25mm

The Exotronic 250W Fusion Fixed Solar Panel combines high-efficiency N-Type TOPCon solar technology with a three-string parallel layout designed to reduce the impact of partial shading.

Delivering a rated 250W from a slim 1715 × 670 × 25mm panel, it is particularly well suited to caravans, RVs, boats and off-grid installations where high solar output and limited roof space need to work together.

⚡ KEY FEATURES

☀️ 250W Rated Output
Provides substantial solar capacity for caravan, RV, marine and larger off-grid battery charging systems.

🌤️ Triple Shade Resistant Design
Three independent cell strings are connected in parallel across the panel's width. If one section becomes shaded, the remaining strings can continue producing power, helping reduce the impact of partial shading.

⚙️ N-Type TOPCon Technology
Uses Tunnel Oxide Passivated Contact solar cells designed for high efficiency, lower degradation and improved low-light performance.

📈 25.2% Cell Efficiency
High-efficiency cells help maximise solar output from the available roof area.

🌥️ Improved Low-Light Response
Designed to maintain useful output under cloudy and variable-light conditions.

🔗 18-Wire Busbar Design
Designed to reduce resistive losses, improve current collection and help reduce hot spots across the cell surface.

🪶 Slim 25mm Profile
The panel measures only 25mm thick and weighs approximately 11.2kg, helping keep overall installation bulk down.

🌊 Salt Mist & Ammonia Resistant
Designed for demanding coastal, marine and mobile environments.

🛡️ 3.2mm Tempered Glass
High-transmissivity low-iron tempered glass provides effective light capture and impact resistance.

⬛ Black Anodised Aluminium Frame
The 25mm aluminium-alloy frame provides structural rigidity while maintaining a clean low-profile appearance.

💧 Fully Potted IP68 Junction Box
Designed to protect electrical connections against dust and moisture ingress.

🔌 MC4-Compatible Connections
Supplied with an approximately 800mm fly lead for flexible installation.

🌤️ BETTER PERFORMANCE AROUND PARTIAL SHADE

The 250W Fusion panel uses three independent parallel cell strings across the width of the panel.

This means shading across one section does not necessarily stop the entire panel from producing power. The unaffected strings can continue operating, making the panel particularly useful on caravan and RV roofs where roof vents, air conditioners, awnings and other equipment may cause intermittent shade.

🚐 IDEAL FOR

• 🚐 Caravans & camper trailers
• 🚙 4WD & vehicle roof installations
• 🚤 Boats & marine applications
• 🌤️ Roofs affected by intermittent partial shading
• 🔋 12V battery charging systems
• 🏠 Remote sheds, cabins & tiny homes
• ⚡ Compatible 24V or 48V off-grid arrays

🔋 DESIGNED FOR 12V & OFF-GRID SOLAR SYSTEMS

With a Vmp of 18.6V and Voc of 21.7V, the Exotronic 250W Fusion panel is suited to compatible 12V battery charging systems when connected through an appropriate solar regulator.

Multiple panels may also be configured for compatible 24V or 48V off-grid systems, subject to the voltage and current limits of the solar controller and connected equipment.

⚠️ A suitable solar regulator or MPPT controller is required when charging a battery. With an Imp of 13.44A and Isc of 14.7A, confirm the controller's solar input current as well as its maximum voltage and array capacity before installation.

❓ QUICK FAQ

What makes the Exotronic 250W panel shade resistant?

It uses three independent solar-cell strings connected in parallel. If one section is shaded, the other strings can continue producing power, helping reduce the effect of partial shading.

How big is the panel?

It measures approximately 1715 × 670 × 25mm and weighs around 11.2kg.

Can it charge a 12V battery?

Yes. It is suited to compatible 12V solar charging systems when used with an appropriate solar regulator or MPPT controller.

Is it suitable for coastal or marine use?

The supplied information states the panel is salt-mist and ammonia resistant and uses a fully potted IP68 junction box.
