Renogy 16BB N-Type 250 Watt Bifacial Fixed Solar Panel

The Renogy RSP250DCT is a 250W N-Type bifacial fixed solar panel designed for compatible 12V battery-charging and off-grid solar systems. Its 16-busbar cell layout, 21.2% listed module efficiency and rear-active bifacial design distinguish it from conventional single-sided fixed panels.

This panel can suit caravans, motorhomes, 4WD canopies, cabins, sheds and other fixed installations when its dimensions, weight, electrical limits and mounting requirements suit the project. A compatible solar charge controller is required between the panel and battery.

Renogy RSP250DCT Specifications

N-Type, 16BB & Bifacial Design

N-Type cells identify the solar-cell technology used in the module. 16BB refers to the multiple busbars that collect current across each cell. These features are specific to this Renogy model and make the page relevant to buyers comparing branded N-Type and bifacial panels rather than a generic 250W panel alone.

The bifacial rear surface can collect reflected light when it remains exposed. Additional rear-side generation is not guaranteed and varies with mounting clearance, surface reflectivity, sun angle, shading, temperature and installation design. A flush installation against an opaque surface may receive little bifacial benefit.

Suitable Caravan, 4WD & Off-Grid Uses

• Caravan and motorhome roofs where the 1547 × 763mm footprint and 12.4kg weight are suitable
• 4WD canopy or rack systems with appropriate structural mounting
• Cabins, sheds and remote battery systems
• Ground or frame-mounted arrays that allow rear-side reflected light
• Compatible lithium or AGM battery charging through an appropriate controller

Measure the available mounting area before ordering and allow for brackets, rails, airflow, cable routing and service access. The mounting structure must withstand the panel weight and expected travel or weather loads.

Solar Charge Controller Compatibility

Do not connect this panel directly to a battery. Select the controller using the panel’s 22.35V Voc and 13.49A Isc, then apply the voltage, temperature and safety margins required by the controller manufacturer.

When panels are connected in series, array voltage increases. With parallel wiring, array current increases. Recalculate the complete array and verify the controller’s PV voltage, PV current, permitted wattage, battery-charging current and supported battery chemistry before connection.

Browse MPPT solar charge controllers, lithium batteries and AGM batteries when planning a matched system.

Real-World Solar Output

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

Avoid regular shade from roof vents, aerials, racks and nearby equipment. Even partial shade can materially reduce the panel’s output.

Installation & Safety

• Follow the current Renogy installation instructions and controller manufacturer requirements.
• Use correctly sized solar cable, compatible connectors, fuses and isolation equipment.
• Keep the complete array within every connected device’s voltage and current limits.
• Use suitable structural mounting hardware and weatherproof cable entries.
• Obtain appropriately qualified advice for structural, fixed or regulated electrical work.

Renogy 250W Solar Panel FAQs

Is this suitable for a nominal 12V battery system?

It can be used in a compatible nominal 12V charging system through an appropriately sized solar charge controller. It must not be connected directly to the battery.

Will the bifacial rear surface always increase output?

No. The rear surface needs reflected light and suitable clearance. The contribution varies with the mounting surface, spacing, sun angle and shade.

Can two Renogy 250W panels be connected together?

Potentially, but the series or parallel arrangement changes the array voltage or current. Confirm the proposed configuration against the controller, cable and protection limits first.

Does this panel suit lithium and AGM batteries?

The panel can charge compatible lithium or AGM systems when the controller supports the battery voltage, chemistry and manufacturer-required charging profile.
