2 x BC Solar Panel 120Wp Black (240Wp)

• 240Wp total power: made up of 2 identical SolarFam BC 120Wp black solar panels.
• Back-contact cells: no visible busbars on the front, for a calm and sleek appearance.
• Compact per panel: 1050 × 580 mm, often suitable for van conversions and smaller camper roofs.
• Bundle discount: more affordable than purchasing the same panels separately.
• IP67 junction box: suitable for outdoor use on camper roofs, provided correctly mounted and connected.
• MC4 connection: standard solar panel connectors, easy to combine with solar cables and MPPT controllers.

Tip: always measure your camper roof thoroughly beforehand. Take into account roof hatches, vents, roof rails, shadows from accessories, and the location of the cable entry. Also, measure the space needed for mounting materials. Roof brackets or spoilers often extend slightly beyond the panel, and the required space depends on the chosen mounting method.

Two solar panels can be connected in series or in parallel. The best choice depends mainly on the position of the panels on the roof, the likelihood of shade, and whether you have a 12V or 24V battery system.

Usually in series for side-by-side panels
If the two panels are situated directly next to each other and almost always experience the same light conditions, series connection is usually the most logical choice. You then connect the positive cable of panel 1 to the negative cable of panel 2. The two remaining cables run through one solar cable set indoors, towards the MPPT charge controller.

• Advantage: higher voltage to the MPPT.
• You still only need 1 solar cable set for the cables going indoors.
• Suitable when both panels receive virtually the same amount of sun.
• For a 24V battery installation, series connection is practically necessary, as a single panel does not provide sufficient voltage for 24V charging.

Parallel for potential uneven shading
Do you expect one panel to be regularly in the shade while the other panel is still fully in the sun? Then a parallel connection might be better. This is more common when panels are not directly next to each other or when roof hatches, vents, rails, or other accessories can cast shadows.

• In parallel, you connect the positive cables of both panels to each other and the negative cables of both panels to each other.
• For this, you use MC4 parallel connectors 2-in-1.
• If the panels are further apart, additional solar cable on the roof is often needed.
• Parallel connection is mainly logical for 12V systems and uneven shading. For 24V, series is usually the right approach.

For this bundle, we recommend the Victron SmartSolar MPPT 100/20. This charge controller is suitable for this 240Wp set and can be used in both 12V and 24V battery installations, provided the panels are connected appropriately.

• Recommended MPPT: Victron SmartSolar MPPT 100/20.
• Bluetooth app: convenient for viewing charging status, yield, and settings via your phone.
• Suitable for multiple battery types: always set the charge controller correctly for your battery type, e.g., AGM, gel, lead-acid, or LiFePO4.
• Connection to the battery: use the battery cable set 6mm² 2 × 1m with 25A fuse.
• Panel cable indoors: in series, you usually need one solar cable set from the roof to the MPPT.
• For parallel: in addition to the solar cable set, also use MC4 parallel connectors 2-in-1.

Do you want less or more solar power? This BC 120Wp panel is available as a single panel and as a bundle with multiple panels. Bundle discounts apply when purchasing multiple panels simultaneously.

• 1 × BC Solar Panel 120Wp Black – 120Wp
• 2 × BC Solar Panel 120Wp Black – 240Wp total
• 3 × BC Solar Panel 120Wp Black – 360Wp total
• 4 × BC Solar Panel 120Wp Black – 480Wp total

This 240Wp bundle is suitable for fixed installation on campers and van conversions where you want to build more solar power with two compact black BC glass panels.

• With 240Wp, you have significantly more charging capacity than with one 120Wp panel.
• A good foundation for campers with a compressor fridge, LED lighting, water pump, phone chargers, and limited laptop use.
• Charging a 12V battery bank via a suitable MPPT charge controller.
• Also applicable to a 24V battery installation when the panels are connected in series and the MPPT is set appropriately.
• Expansion of an existing camper installation with additional solar power.
• Suitable as part of a complete off-grid system with battery, MPPT, alternator charger, and/or shore power charger.

These panels are usually mounted with aluminum roof brackets or spoilers. Ensure a strong mechanical mounting, good sealing, and a neat cable routing indoors.

• Van conversion: preferably use aluminum Z-profiles on a ribbed or slightly curved metal roof.
• Flat camper roof: use 55 cm spoilers and preferably place the panels lengthwise.
• Boat: use plastic corner brackets on a suitable flat deck.
• Thoroughly degrease the roof and follow the instructions for the adhesive, sealant, and primer used.
• Use an appropriate roof gland for the solar cables.
• Secure cables on the roof firmly with UV-resistant adhesive bases and zip ties.
• Prevent cables from chafing, kinking, or moving loosely while driving.

• Mounting: aluminum Z-profiles for a van conversion, 55 cm spoilers for a flat camper roof, or plastic corner brackets for a boat.
• Roof gland for solar cables
• Solar cable set 4mm² indoors
• Victron SmartSolar MPPT 100/20
• Battery cable set 6mm² 2 × 1m with 25A fuse
• MC4 parallel connectors 2-in-1, only needed if you want to connect the panels in parallel
• Optionally, extra custom solar cable if the panels are further apart.

• Connecting solar panels directly to a battery without a charge controller.
• Connecting two panels in series when one panel regularly gets shade and the other doesn't.
• Connecting in parallel without the correct MC4 parallel connectors and without accounting for extra current through the cables.
• For a 24V battery installation, connecting the two panels in parallel, which can result in insufficient panel voltage for proper charging.
• Using an MPPT that is too small or unsuitable for 240Wp solar power.
• Combining panels with different voltages or powers without checking specifications.
• Using cables that are too thin for longer cable lengths, leading to unnecessary voltage drop.
• Not installing a fuse or DC protection on the battery side of the charge controller.
• Leaving cables loose on the roof, risking chafing, leaks, or cable breaks.
• Insufficiently sealing the roof gland or using the wrong sealant/primer for the roof material.

Should I connect two BC 120Wp panels in series or parallel?
If the panels are directly next to each other and almost always receive the same sunlight, series is usually logical. If you expect regular shade on one of the two panels, then parallel might be better.

Why multiple smaller panels instead of one large solar panel?
One large solar panel is often cheaper per watt, but on a camper roof, this is not always the best choice. With multiple smaller panels, you have more flexibility in the layout of your roof, for example, around roof hatches, vents, or rails. Additionally, smaller panels are often stiffer and therefore practically less fragile than large residential panels. Our experience, and that of several camper builders, is that smaller solar panels on campers often last longer and pose less risk when mounted on a vehicle.

Can I use this bundle for a 24V battery?
Yes, but you would typically connect the two panels in series. Parallel connection usually results in insufficient panel voltage for proper charging with a 24V battery installation.

Do I need extra connectors for series connection?
No, usually not. You connect the positive of one panel to the negative of the other panel. The two remaining cables go indoors via one solar cable set.

What do I need for parallel connection?
For parallel connection, you use MC4 parallel connectors 2-in-1. If the panels are further apart, custom solar cable may be needed.

Which MPPT charge controller do you recommend?
For this bundle, we recommend the Victron SmartSolar MPPT 100/20. This is suitable for this 240Wp set and can be used with both 12V and 24V battery installations, provided the panels are connected appropriately.

Which battery cable set is suitable for this MPPT?
For connecting the MPPT to the battery, we recommend the battery cable set 6mm² 2 × 1m with 25A fuse.

Is 240Wp enough for my camper?
That depends on your consumption and travel habits. 240Wp is often a good baseline for normal camper use, but with high consumption, winter use, or several days off-grid, battery capacity and charging via alternator or shore power also remain important.
