Our take on the ECO-Baeerss N-Type 18BB 300W Bifacial Solar Panel Mono 12/24V Charging Camping Home PV Off-Grid RV Boat

A 300W monocrystalline bifacial panel rated at 18.8V and 16.0A, sized for 12V and 24V off-grid charging on RVs, boats and camps. Its 18BB cell layout and bifacial design aim to capture reflected light from the rear side, which can add output over a plain single-sided panel when mounted over a light surface. The 22.4V open-circuit voltage leaves headroom for a PWM or MPPT charge controller. It is a large, heavy glass panel, so plan mounting and handling before buying.

Pros
  • Bifacial design can pick up reflected light from the rear
  • 18BB cell layout for current collection
  • 18.8V Vmp suits 12V and 24V off-grid systems
  • 22.4V Voc leaves controller headroom
  • Monocrystalline cells for compact output
Cons
  • Large 1340 x 670 mm footprint needs serious mounting
  • 30 mm frame and glass add weight to handle
  • Bifacial gain depends on mounting height and surface
  • ±3% power tolerance means real output varies

Questions and answers

Will this charge a 12V battery directly?
Its 18.8V Vmp is high for direct 12V charging, so use a charge controller. A PWM or MPPT controller rated above 20.5A Isc is the safe choice.
Can I use it on a 24V system?
Yes. The 22.4V Voc and 18.8V Vmp suit 24V off-grid charging through an MPPT controller, which handles the voltage step-up better than PWM.
How much extra does the bifacial rear side give?
It depends on mounting height and the surface below. Over a light, reflective roof or ground with the panel raised, expect a modest gain; mounted flat and close to a dark surface, gain is small.
What is in the box?
One 300W bifacial solar panel. Mounting hardware, cables and a charge controller are not included.
Is it too big for a van roof?
At 1340 x 670 mm it fits many van roofs but takes a large share of the space. Measure your roof and account for mounting rails before committing.
