A motorhome solar kit supplies your vehicle with clean solar energy, independent of shore power. The solar panels, either on the roof or in a portable version, convert sunlight into electrical energy. This energy is controlled by a charge controller , which regulates the current flow to the vehicle's battery and protects the battery from overcharging or deep discharging.

The stored energy is then available for all consumers in the vehicle – from the lights to the refrigerator to the laptop.

With an inverter, you can even convert the 12-volt DC voltage of the battery into 230 volts to operate normal household appliances.

A complete set contains all the necessary components – modules, charge controllers, cables, plugs and mounting material – optimally matched for maximum efficiency and easy installation.

To know how much solar power you need, you should realistically estimate your daily energy consumption .

Here's how to do it:

1. List all the devices you use – e.g., lights, refrigerator, mobile phone, laptop, water pump.
2. Note their power output (watts) and usage time (hours per day) .
3. Multiply power × usage time = consumption in watt-hours (Wh) .
4. Add the values ​​together – that gives you your daily consumption.
5. Divide the total by the battery voltage (12 V or 24 V) → Your consumption in ampere-hours (Ah) .

👉 Even easier: Use our solar calculator .

It automatically calculates your individual consumption and shows you which complete motorhome solar kit suits your energy needs – including battery size and recommended module power.

The required solar power depends on several factors:

• Your daily electricity consumption
• The season and sunlight
• The desired self-sufficiency time (how long you want to stand without recharging)

For guidance:

• 200 W is sufficient for basic needs (lights, mobile phone, laptop).
• 400–600 W is suitable for refrigerators, water pumps and longer periods of inactivity.
• From 800 W upwards you are ideally equipped for more energy-intensive devices and longer off-grid stays.

Our tip: Plan for some extra power – that way you're on the safe side even under cloudy skies.

With our solar calculator , you can easily check how much power your motorhome really needs.

Yes – most motorhome solar kits can be installed yourself with a little DIY skill. Our complete kits already include all components and the necessary mounting hardware . However, you should note the following points:

• Cable cross-section & fuses: Always size them appropriately for the current. Use our calculator (link) to calculate your required cable cross-section.
• Mounting: Mount modules securely, vibration-proof and watertight (e.g. with roof penetrations and brackets).
• Connections: Check polarity, make clean crimp connections.
• Charge controller & battery: Place as close together as possible to minimize line losses.

If you are unsure, a quick check by a specialist workshop is recommended – especially for larger systems or 230 V systems.
