3 x SolarFam Mono Black 100Wp (300Wp)

• 300Wp total power: built from 3 identical SolarFam Mono 100Wp Black solar panels.
• Narrow size per panel: 1190 × 450 mm, convenient for camper roofs with limited or fragmented roof space.
• Bundle discount: more affordable than buying the same panels individually.
• Black finish: black frame and dark cell construction for a sleek appearance on the roof.
• MC4 connection: standard solar panel connectors, easy to combine with solar cables and MPPT controllers.
• IP67 junction box: suitable for outdoor use on camper roofs, provided correctly mounted and connected.

Tip: always measure 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 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.

Three solar panels can be connected in series or in parallel. The best choice mainly depends on the position of the panels on the roof, the likelihood of shade, and the chosen MPPT charge controller.

Usually in series for panels next to each other
Are the three panels directly next to each other and do they almost always have the same light conditions? Then series connection is usually the most logical choice. You connect the positive cable of one panel to the negative cable of the next panel. The two remaining cables run through a single solar cable set to the inside, towards the MPPT charge controller.

• Advantage: higher voltage to the MPPT.
• You still only need 1 solar cable set for the cables to the interior.
• Suitable when all panels receive virtually the same sun.

Parallel for unequal shade probability
Do you expect one or two panels to be regularly in shade while the other panels are still in full sun? Then parallel connection might be better. This is more common when the panels are not directly next to each other or when roof hatches, fans, rails, or other accessories can cast shade.

• For parallel connection, you connect the positive cables of the three panels together and the negative cables of the three panels together.
• For this, you use MC4 parallel connectors 3-in-1.
• Are the panels further apart? Then additional solar cable on the roof is often necessary.

For this bundle of 3 × 100Wp, for a 12V battery installation, we usually recommend the Victron SmartSolar MPPT 100/30. This MPPT charge controller is a practical choice for 300Wp of solar power on a compact camper installation.

The Victron SmartSolar MPPT 100/30 offers sufficient charging capacity for 300Wp on a 12V battery installation, without the controller having to limit power at peak output.

• Recommended MPPT for 12V: Victron SmartSolar MPPT 100/30.
• Battery connection for 12V: use 10mm² battery cable with a 40A MIDI fuse and MIDI fuse holder.
• Battery connection for 24V: use the 6mm², 2 × 1m battery cable set with 25A fuse.
• Panel cable to interior: 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 3-in-1.

Are you using a 24V battery installation?
Then you can use this bundle by connecting the three panels in series. For a compact 24V installation, the Victron SmartSolar MPPT 100/20 is usually sufficient.

Do you want less or more solar power? This SolarFam 100Wp panel is available as a single panel and as a bundle with multiple panels. A bundle discount applies when purchasing multiple panels simultaneously.

• 1 × SolarFam Mono 100Wp Black – 100Wp
• 2 × SolarFam Mono Black 100Wp – 200Wp total
• 3 × SolarFam Mono Black 100Wp – 300Wp total
• 4 × SolarFam Mono Black 100Wp – 400Wp total

This 300Wp bundle is suitable for fixed mounting on campers and van conversions where you want to build more solar power with three narrow glass panels.

• With 300Wp, you'll reach a practical range for many camper installations.
• Suitable as a charging source for installations with a compressor fridge, LED lighting, water pump, fan, and charging phones or laptops.
• Charging a 12V battery bank via a suitable MPPT charge controller.
• Expanding an existing camper installation with additional solar power.
• Flexible roof layout due to three narrow panels instead of one large panel.
• Suitable as part of a complete off-grid system with battery, MPPT, dynamo charger, and/or shore power charger.

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

• Van conversion: preferably use aluminum Z-profiles on a ribbed or slightly curved metal roof.
• Flat camper roof: use 45 cm spoilers and preferably place the panels lengthwise.
• Boat: use plastic corner mounts on a suitable flat deck.
• Thoroughly degrease the roof and follow the instructions for the adhesive, sealant, and primer used.
• Use a suitable roof entry for the solar cables.
• Secure cables on the roof firmly with UV-resistant adhesive mounts and cable ties.
• Prevent cables from chafing, kinking, or moving loosely while driving.

• Aluminum roof mounts or 45 cm spoilers
• Roof entry for solar cables
• Solar cable set 4mm² to the interior
• Victron SmartSolar MPPT 100/30 for a 12V battery installation
• Victron SmartSolar MPPT 100/20 for a compact 24V battery installation with three panels in series
• Battery cable set 6mm² 2 × 1m with 25A fuse
• MC4 parallel connectors 3-in-1, only needed if you want to connect the panels in parallel
• Possibly extra custom solar cable if the panels are further apart.

• Connecting solar panels directly to a battery without a charge controller.
• Connecting three panels in series when one panel regularly receives shade and the others do not.
• Parallel connection without the correct MC4 parallel connectors and without accounting for extra current through the cables.
• Using an undersized or unsuitable MPPT for 300Wp solar power.
• For series connection, not checking if the maximum input voltage of the MPPT remains suitable even at low temperatures.
• 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 installing a fuse or DC protection on the battery side of the charge controller.
• Leaving cables loose on the roof, risking chafing, leakage, or cable breaks.
• Insufficiently sealing the roof entry or using the wrong sealant/primer for the roof material.

Why multiple smaller panels instead of one large solar panel?
For this total power output, one large solar panel might seem like an alternative. Such a large panel is often cheaper per watt, but on a campervan roof, this is not always the best solution. Multiple smaller panels offer more freedom in arranging your roof and are easier to place around roof hatches, fans, or other obstacles. Additionally, smaller panels are often stiffer than large household panels. Our experience, and that of several campervan builders, is that smaller solar panels on campervans often last longer and pose less risk in practice than large panels with a long and wide frame.

Should I connect three 100Wp panels in series or parallel?
If the panels are placed directly next to each other and almost always receive the same sunlight, then series connection is usually logical. Do you expect regular shading on one or more panels? Then parallel connection might be better.

Do I need extra connectors for series connection?
No, usually not. You simply connect the positive of one panel to the negative of the next 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 3-in-1. If the panels are further apart, custom-length solar cable may be required.

Which MPPT charge controller do you recommend for 12V?
For this bundle, we usually recommend the Victron SmartSolar MPPT 100/30. In practice, this is a good choice for 3 × 100Wp on a 12V campervan installation.

Can I also use this bundle for a 24V battery?
Yes, if you connect the three panels in series and use an appropriate MPPT charge controller. For a compact 24V installation, the Victron SmartSolar MPPT 100/20 is usually sufficient. However, always check the maximum input voltage of the controller.

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

Is 300Wp enough for my campervan?
That depends on your consumption and travel habits. 300Wp is a practical base for many campervan installations, but with high consumption, winter use, or several days of off-grid camping, battery capacity and charging via alternator or shore power remain important.
