150W flexible monocrystalline TOPCon solar panel

150W semi-flexible monocrystalline N-type TOPCon solar panel

This 150W semi-flexible TOPCon solar panel is designed for installations where weight, thickness and easy integration are important. Measuring 1294 × 610 × 2 mm and weighing 3.1 kg net, it can provide solar generation where a rigid module may be less practical.

Its 150W output, 900 mm cables with MC4 connectors and junction box rated at least IP67 make it suitable for motorhomes, campervans, boats, vehicles, auxiliary systems and small off-grid installations.

Why choose this product?

It is a practical option when a lightweight, low-profile panel is required in a limited space. The semi-flexible format helps with installation on vehicle roofs, boats and gently curved surfaces.

The 150W output can support leisure batteries, small auxiliary electrical systems and moderate loads when used with a compatible charge controller and correctly sized battery.

Main benefits

• 150W output: suitable for auxiliary solar systems and moderate loads.
• Semi-flexible format: easier to integrate where a rigid panel is less practical.
• Only 2 mm thick: suitable for discreet, low-profile installations.
• Low weight: 3.1 kg net for lightweight roofs, campers and marine use.
• N-type TOPCon technology: advanced photovoltaic cell technology.
• MC4 connection: compatible with standard solar cabling.
• Protected junction box: rated at least IP67.

Technology explained

N-type TOPCon technology uses passivated-contact cells designed to improve electrical performance compared with conventional technologies. It provides useful solar generation in a compact, lightweight format.

The CPC / EVA / backsheet construction combines an outer protective layer, EVA encapsulation and a supporting rear layer to reduce weight and thickness.

A semi-flexible panel is not rollable. It can follow a gentle curve but must not be sharply bent or twisted, as forced installation may cause microcracks and reduce performance.

Recommended applications

• Motorhomes: auxiliary generation for leisure batteries, lighting, ventilation and water pumps.
• Campervans: lightweight roof installation with reduced height.
• Marine use: energy support on boats where low weight aids integration.
• Commercial vehicles: regulated supply or maintenance of auxiliary systems.
• Battery maintenance: helps offset small loads or self-discharge in 12V systems.
• Portable solar systems: projects requiring low weight and easy transport.
• Technical applications: off-grid systems, education and low-power projects.

Compatibility

The panel uses MC4 connectors and can work with PWM or MPPT controllers that accept its open-circuit voltage, short-circuit current and total installed power.

Always confirm compatibility against the controller specifications. Never connect the panel directly to a battery.

Check compatibility in 30 seconds

1. Make sure the controller accepts more than 26.52V open-circuit voltage.
2. Check that the input supports more than 7.03A per panel.
3. Confirm that its photovoltaic power rating permits 150W or the combined installed output.
4. For series connections, add the open-circuit voltages.
5. For parallel connections, add the short-circuit currents.
6. Check that the charge profile matches the battery.
7. Do not connect the panel directly to a battery.

Installation recommendations

Install the panel on a clean, stable surface compatible with the chosen fixing method. Avoid constant partial shade, sharp edges, standing water and areas subject to repeated flexing.

Allow sufficient ventilation where possible. Do not force the panel onto a surface that deforms while the vehicle is moving.

Orientation and angle affect production. Avoid shadows from aerials, rooflights, racks, masts and accessories.

Charging recommendations

Always use a compatible solar charge controller to adapt the generated energy to the battery charge profile.

For AGM, GEL, flooded lead-acid or LiFePO4 batteries, configure the controller according to the battery manufacturer’s instructions.

Storage recommendations

Store the panel in a dry, clean place protected from impacts. Do not store it folded, under pressure or with weight on top.

Protect the MC4 connectors and cables from moisture, dirt and pulling. Inspect the surface, connections and junction box before installation.

How to extend service life

• Clean the surface using water and non-abrasive products.
• Do not step on the panel or place tools on it.
• Avoid excessive bending, twisting and repeated flexing.
• Inspect connectors, cables and fixings regularly.
• Avoid permanent partial shade.
• Always use a compatible controller.
• Do not exceed the controller electrical limits.
• Check the adhesive, support or fixing after long journeys.

Temperature effects

Heat can reduce operating voltage, while cold conditions can increase open-circuit voltage. The declared operating range is −20°C to +65°C.

With several panels, particularly in series, calculate maximum voltage at low temperature so that the controller limit is not exceeded.

Actual production depends on orientation, angle, sunlight, season, cleanliness and shading. Nominal power is measured under favourable test conditions.

Technical specifications

Frequently asked questions

Can it charge a 12V battery?

Yes, when installed with a compatible controller configured for the battery.

Can I connect it directly to a battery?

No. A solar charge controller must always be used.

Which controller do I need?

A PWM or MPPT controller rated for at least 150W, more than 26.52V open-circuit voltage and more than 7.03A per panel.

Is it compatible with MPPT controllers?

Yes, provided the controller accepts the electrical values and total installed power.

Can it be installed on a motorhome or campervan?

Yes. Its low weight, reduced thickness and semi-flexible construction aid discreet installation.

Can it be used on a boat?

Yes, with correct installation, protected cabling and a compatible controller.

Can it be walked on?

No. Point loads may damage the cells.

What maintenance is required?

Regularly inspect the connectors, cables and fixings and clean the surface with non-abrasive products.
