180W Monocrystalline Back Contact Solar Panel

180W monocrystalline Back Contact solar panel

This rigid 180W solar panel is designed to generate electricity in photovoltaic systems where installation space is limited. Its narrow 1430 × 580 × 30mm format suits campervans, caravans, motorhomes, boats and off-grid solar systems, provided its electrical ratings match the controller and the rest of the installation.

Electrical performance and compatibility

Under standard test conditions it delivers 180W nominal power, with 20.96V and 8.59A at the maximum power point. Open-circuit voltage is 23.93V and short-circuit current is 9.11A. Before connection, check that the controller’s photovoltaic input accepts these values, particularly the open-circuit voltage and the total current of the panel array.

Construction for outdoor use

The module combines a black aluminium frame, glass, EVA encapsulation and a backsheet. It includes 700mm, 2.5mm² cable with MC4 connectors. The junction box is rated at least IP67 and the stated operating-temperature range is −40 to +85°C.

Technical specifications

Recommended applications

It can be used in campervans, caravans, motorhomes, boats, telecommunications equipment, cabins, off-grid homes and smaller solar systems. Final compatibility depends on the available space, charge controller, battery and complete electrical configuration.

Which charge controller is required?

The panel must not be connected directly to a battery. Use a solar charge controller compatible with its 23.93V open-circuit voltage, 9.11A short-circuit current, total installed power and the battery voltage and chemistry. With several panels, recalculate array voltage and current according to the series or parallel connection.

Real-world output and installation

The 180W rating is the nominal power measured under standard test conditions. Actual output varies with sunlight, orientation, tilt, temperature, shading, wiring and controller losses. Install it on a surface capable of supporting its dimensions and weight, using suitable mounts, correctly sized solar cable, electrical protection and the correct polarity.

Frequently asked questions

Can it be connected directly to a battery?

No. A compatible charge controller must be installed between the panel and the battery.

Is it a rigid panel?

Yes. Its construction uses an aluminium frame, glass, EVA and a backsheet.

Are connectors included?

Yes. It includes 700mm, 2.5mm² cable with MC4 connectors.

Does the IP67 rating cover the entire panel?

The stated minimum IP67 rating applies to the junction box; the complete installation must still be properly sealed and protected.
