Solar Panel flexible monocrystalline 180W

180W TOPCon-N CPC Semi-Flexible Solar Panel

The 180W TOPCon-N CPC semi-flexible solar panel is designed for solar installations where weight, thickness and ease of integration are decisive factors. With dimensions of 1270 x 790 x 2 mm and a net weight of 3.9 kg, it enables photovoltaic generation on surfaces where a traditional rigid panel may be too heavy, too high or difficult to install.

This panel provides 180W nominal power, 22.04V maximum power voltage and 8.17A maximum power current. It includes MC4 connectors, 900 mm cable and a junction box rated ≥ IP67, making it suitable for correctly sized solar systems.

Why choose this product?

This panel is suitable when a lightweight, low-profile solar module with good generation capacity is required in limited spaces. Its semi-flexible format makes it easier to install on vehicle roofs, boats, caravans, campervans and surfaces where a rigid panel may not be the most practical option.

The 180W output can support service batteries, auxiliary electrical systems and moderate loads in mobile or off-grid installations, provided that it is used with a compatible solar charge controller and a properly sized battery.

Main advantages

• 180W power: suitable for auxiliary solar systems, vehicles, boats and low to medium demand applications.
• Semi-flexible format: easier to install where a rigid panel may be less practical.
• Reduced thickness: only 2 mm, ideal for discreet low-profile installations.
• Low weight: 3.9 kg net weight, useful for lightweight roofs, campervans, motorhomes and marine use.
• TOPCon-N technology: advanced photovoltaic technology focused on improving module electrical performance.
• MC4 connection: compatible with standard solar wiring and common photovoltaic controllers.
• Protected junction box: protection rating stated as equal to or higher than IP67.

Technology explanation

TOPCon-N technology uses N-type cells with a passivated contact structure designed to improve the electrical behaviour of the panel compared with conventional technologies. In practical terms, it helps deliver good generation in a compact and lightweight format.

The CPC / EVA / backsheet construction combines an outer protective layer, EVA encapsulation and a rear support layer. This structure is intended to reduce weight and thickness while maintaining a practical design for mobile and low-profile solar applications.

A semi-flexible panel is not a rollable panel. It can adapt to slightly curved surfaces, but it must not be sharply bent or twisted. Forced installation may cause cell microcracks and performance loss.

Recommended applications

• Motorhomes: auxiliary generation for service batteries, lighting, ventilation, water pumps and small loads.
• Campervans: lightweight solar installation on roofs where reducing weight and height is important.
• Marine use: energy support on boats where a lightweight low-profile panel is easier to integrate.
• Industrial vehicles: power support or maintenance for correctly regulated auxiliary systems.
• Battery maintenance: helps compensate small loads or self-discharge in 12V systems with a suitable controller.
• Portable solar systems: projects requiring photovoltaic power with low weight and easy transport.
• Technical applications: off-grid installations, educational projects, solar testing and low-power systems.

Compatibilities

This panel uses MC4 connectors and has the electrical values of a 180W photovoltaic module. It can be used with PWM or MPPT solar charge controllers as long as they accept the panel open-circuit voltage, short-circuit current and total installed power.

No official compatibility list with specific controller, inverter or solar system brands is confirmed. Compatibility must therefore always be checked using the technical specifications of the controller.

How to check compatibility in 30 seconds

• Check that the solar controller accepts an open-circuit voltage above 25.84V.
• Verify that the controller input supports current above 8.66A per panel.
• Confirm that the controller maximum PV power allows 180W or the total sum if several panels are installed.
• If panels are connected in series, add the open-circuit voltage values.
• If panels are connected in parallel, add the short-circuit current values.
• Check that the controller has a charging profile compatible with the battery used.
• Do not connect the panel directly to a battery without a solar charge controller.

Installation recommendations

Install the panel on a clean, stable surface compatible with the chosen mounting system. Avoid constant partial shading, sharp edges, water accumulation and points exposed to repeated flexing.

Whenever possible, allow enough ventilation to improve the thermal behaviour of the panel. Although it is semi-flexible, it should not be installed under stress or on surfaces that deform during movement.

Orientation and tilt directly affect production. In fixed installations in the northern hemisphere, the panel should face south whenever possible, avoiding shadows from antennas, roof windows, racks, masts or accessories.

Charging recommendations

The panel must always be used with a compatible solar charge controller. The controller adapts the energy generated by the panel to the battery charging profile and helps avoid overcharging, unsuitable voltages or incorrect charging.

For AGM, GEL, flooded lead-acid or LiFePO4 batteries, configure the controller with the values recommended by the battery manufacturer. Incorrect settings may reduce battery life or cause operating errors.

Storage recommendations

If the panel is not installed immediately, store it in a dry, clean place protected from impacts. It must not be stored bent, under pressure or with weight placed on top.

MC4 connectors and cable must be protected from moisture, dirt and pulling forces. Before installation after long storage, visually check the surface, connections and junction box.

How to extend service life

• Clean the surface periodically with water and non-abrasive products.
• Do not step on the panel or place tools or loads on it.
• Avoid excessive bending, twisting or repeated flexing.
• Periodically check connectors, cables and fixing points.
• Avoid permanent partial shading on the same area.
• Always use a compatible solar controller.
• Do not exceed controller electrical limits if several panels are installed.
• Check the adhesive, support or fixing system after long trips or intense sun exposure.

Temperature influence

Temperature affects the performance of any solar panel. In hot conditions, operating voltage may decrease; in cold conditions, open-circuit voltage may increase. This panel declares a working range from -20 ºC to +65 ºC.

In installations with several panels, especially in series, maximum voltage under low-temperature conditions must be calculated to avoid exceeding the controller input limit.

Real production also depends on orientation, tilt, solar radiation, season, panel cleanliness and absence of shading. Nominal power is reached only under favourable test conditions and does not represent constant production throughout the day.

Technical specifications

Frequently asked questions

Can this solar panel charge a 12V battery?

Yes, it can be used in 12V systems if installed with a compatible solar charge controller correctly configured for the battery used.

Can I connect it directly to a battery?

No. Direct connection may cause incorrect charging or battery damage. A solar charge controller must always be used.

What controller do I need?

Choose a PWM or MPPT controller that supports at least 180W of photovoltaic power, open-circuit voltage above 25.84V and input current above 8.66A per panel.

Is it compatible with MPPT controllers?

It can be compatible if the controller accepts the electrical values of the panel and the total installed power.

Can it be installed on a motorhome or campervan?

Yes. Its low weight, reduced thickness and semi-flexible format make it suitable for lightweight and discreet solar installations.

Can it be used on a boat?

Yes, if correctly installed with protected wiring and a compatible solar controller.

Can it be walked on?

It is not recommended. Point loads can damage the solar cells even though the panel is semi-flexible.

What maintenance does it need?

Periodic inspection of connectors, cables and fixings, plus surface cleaning with non-abrasive products.
