The SolarFam BC 120Wp black solar panel is a compact glass panel for campers and van conversions. With its dimensions of 1050 × 580 mm, this panel often fits well on roofs with limited available space, for example next to a roof hatch, fan, or roof rail.

This panel uses BC / HPBC back-contact solar cells. On the front, there are no prominent busbars, giving the panel a clean, completely black appearance. Combined with the black frame, this is a neat choice for a fixed solar panel installation on a camper roof.

Why this BC 120Wp panel? ▾
  • Back-contact cells: no visible busbars on the front, for a clean and sleek appearance.
  • 120Wp nominal power: suitable for maintenance charging and daily basic users.
  • Compact format: 1050 × 580 mm, often well suited for van conversions and smaller camper roofs.
  • High cell efficiency: according to the datasheet >25% cell efficiency.
  • IP67 junction box: suitable for outdoor use on camper roofs, provided it is correctly mounted and connected.
  • MC4 connection: standard solar panel connectors, easy to combine with solar cables and MPPT controllers.
The actual yield depends heavily on the season, solar radiation, shade, panel orientation, and the charge status of your battery. In winter or in shade, the yield is significantly lower than on a sunny summer day.

Tip: always measure out your camper roof carefully beforehand. Take into account roof hatches, fans, roof rails, shade from accessories, and the location of the cable entry. Also measure the required space for the mounting material. Roof supports or spoilers often protrude slightly beyond the panel and the required space depends on the chosen mounting method.

Also available as a bundle with a discount ▾

Do you want to install multiple BC 120Wp solar panels of the same type? Then you can choose a bundle with multiple panels. When purchasing multiple panels at the same time, a bundle discount applies.

Note: with multiple panels, the choice of the correct MPPT charge controller and the wiring method also changes. Series, parallel, or series-parallel depends on the number of panels, your battery installation, the cable length, and the chance of shade on the roof.
What is this panel suitable for? ▾

This 120Wp solar panel is suitable for fixed mounting on campers, van conversions, and other compact off-grid applications where a plain black glass panel is desired.

  • Maintenance charging of a household battery.
  • Top-up charging of a 12V battery bank via a suitable MPPT charge controller.
  • Daily basic users such as LED lighting, phone chargers, water pump, and ventilation.
  • Expansion of an existing camper installation with additional solar power.
  • A neat solution when the appearance on the roof is important.
Do you use a compressor refrigerator, laptop, inverter, or want to be off-grid for several days? Then one 120Wp panel is often a useful basis, but usually not sufficient as the only charging source. Then look at multiple panels, a larger battery capacity, and possibly charging via alternator or shore power.
Mounting on a camper roof ▾

You usually mount this panel with aluminum roof supports or spoilers. Ensure a strong mechanical mounting, good sealing, and a neat cable route inside.

This panel is wider than the narrow 100Wp Mono Black panel. Therefore, when mounting with spoilers, we recommend the 55 cm spoilers rather than the 45 cm spoilers.
Connecting to battery and MPPT ▾

Do not connect this solar panel directly to the battery. Always use a suitable charge controller, preferably an MPPT charge controller. It converts the panel voltage to a suitable charging voltage for your battery.

  • Use UV-resistant solar cable between the panel and charge controller.
  • For one panel on a 12V battery installation, the Victron SmartSolar MPPT 75/10 is usually a suitable choice.
  • Always place a fuse or suitable DC protection on the battery side of the MPPT.
  • For example, use a 4mm² battery cable set with 15A fuse for smaller systems.
  • With multiple panels: check if the maximum input voltage and charging current of the MPPT are suitable.
One separate 120Wp panel is intended for charging a 12V battery via MPPT. For a 24V battery installation, you practically need multiple panels in series, so that the panel voltage is high enough. Feel free to send us your plans, then we will look at which controller and wiring are suitable.

Common mistakes ▾
  • Connecting the solar panel directly to a battery without a charge controller.
  • Trying to charge a 24V battery with one separate 120Wp panel and a standard MPPT.
  • Using an MPPT that is too small or unsuitable for multiple panels.
  • Combining panels with different voltages or powers without checking the specifications.
  • Using cables that are too thin for longer cable lengths, causing unnecessary voltage drop.
  • Not placing a fuse or DC protection on the battery side of the charge controller.
  • Leaving cables loose on the roof, with the risk of rubbing, leakage, or cable breakage.
  • Insufficiently sealing the roof entry or using the wrong sealant/primer for the roof material.
FAQ ▾

What is the advantage of BC / HPBC solar cells?
With back-contact cells, the electrical contacts are on the back of the cell. Therefore, the front has no prominent busbars. This gives a clean appearance and can help with good light utilization.

Is this a 12V solar panel?
This panel is often used in 12V camper systems, but you do not connect it directly to a 12V battery. You use a suitable MPPT charge controller between the solar panel and the battery.

Can I charge a 24V battery with one panel?
No, in practice, one 120Wp panel is not suitable for this with a standard MPPT charge controller. For a 24V battery installation, you need multiple panels in series or a solar panel with a higher panel voltage.

Which MPPT do you recommend for one panel?
For one BC 120Wp panel on a 12V battery installation, the Victron SmartSolar MPPT 75/10 is usually a suitable choice.

Does this panel fit on every camper roof?
Not always. The panel is compact, but it is 580 mm wide. Therefore, measure carefully beforehand if the panel fits next to roof hatches, fans, rails, and other obstacles. Also take into account extra space for the chosen roof supports or spoilers.

Which spoilers fit this panel?
Because this panel is 580 mm wide, we usually recommend 55 cm spoilers for spoiler mounting.
