This 250W 12V bifacial monocrystalline fixed solar panel is a compact option for compatible caravan, camper, 4WD, marine and off-grid battery systems. Its 760 × 585 mm frame suits installations where available mounting area matters, while the bifacial design can collect additional reflected light through the rear surface when it remains exposed.

250W Bifacial Solar Panel: Key Specifications

How Bifacial Solar Panels Work

A bifacial solar panel can generate power from direct light on the front surface and reflected light reaching the rear. The additional contribution is not fixed: it depends on the mounting clearance, surface reflectivity, sun angle, shading, temperature and installation design.

For better rear-side exposure, avoid mounting the panel directly against an opaque surface where no reflected light can reach the back. A light-coloured roof or other reflective surface may help, but actual output should be measured under the conditions of your installation.

Suitable Caravan, 4WD & Off-Grid Applications

• Caravan and camper-trailer roof arrays where the dimensions and weight suit the available structure
• 4WD canopies and touring systems with compatible mounting
• Sheds, cabins and small independent-power systems
• Marine or remote installations where the mounting method and environment are suitable
• Charging compatible 12V lithium or AGM battery systems through an appropriate controller

Before ordering, measure the mounting area and allow for brackets, cable routing, ventilation and service access. Confirm that the supporting surface and mounting hardware are suitable for an 8 kg framed panel and the loads expected during travel or severe weather.

Charge Controller Compatibility

Do not connect the panel directly to a battery. Use a compatible solar charge controller and check its maximum PV voltage, input current, charging current and supported battery chemistry.

For controller selection, use the panel’s 21.4V Voc and 14.8A Isc, then allow the safety and temperature margins required by the controller manufacturer. When combining panels, series wiring increases voltage and parallel wiring increases current. Recalculate the complete array before connection.

What This Panel Can Produce

The 250W rating is measured under standard test conditions. Real output varies with sunlight, panel temperature, orientation, shade, cable losses, controller performance and rear-side exposure. Use realistic daily energy requirements and local solar conditions when sizing the array and battery bank.

Partial shade can materially reduce output. Install the panel where roof vents, aerials, racks and nearby equipment are unlikely to cast regular shadows across the solar cells.

Installation & Safety

• Follow the product and controller manufacturer’s wiring instructions.
• Use correctly sized solar cable, connectors, fuses and isolation equipment.
• Keep the total array voltage and current inside every connected device’s limits.
• Use suitable mounting hardware and weatherproof cable entries.
• Obtain appropriately qualified installation advice where structural or regulated electrical work is involved.

250W Solar Panel FAQs

Is this a “12V” solar panel?

It is designed for use in compatible nominal 12V charging systems through a suitable controller. The panel’s operating voltage is listed as 18V, so it must not be connected directly to a 12V battery.

Will bifacial output always be higher?

No. Additional rear-side generation depends on reflected light reaching the back of the panel. A flush-mounted installation with an obstructed rear surface may receive little bifacial benefit.

Can I connect two panels together?

Potentially, but the controller, cabling and protection must suit the combined voltage and current. Confirm the proposed series or parallel configuration before connection.

Is it suitable for lithium and AGM batteries?

It can charge compatible lithium or AGM systems when used with a controller configured for the battery voltage, chemistry and manufacturer requirements.
