Product description
WATTSTUNDE SolarBuddys – Energy to go.
The new WATTSTUNDE® SolarBuddy combines the lightness of solar bags with the robustness of solar cases and flexibly supplies you with power – exactly where you need it.
The portable solar panel:
A solar bag is a foldable solar panel. It consists of one or more solar panels built into a fabric bag. The advantage over a built-in solar system is obvious ->
The solar bag can be flexibly set up in the sun when needed and does not have to be permanently mounted on the vehicle.
The days when your motorhome or car had to be parked unfavorably in the sun are over. You can park comfortably in the shade and still soak up the sun. Whether in the garden, while camping, or on the boat - everywhere there is no power outlet, there is now always power available!
Always ready for use, even without a charge controller:
Of course, the SolarBuddy is most effective when used in combination with a charge controller and a battery to store the generated energy.
Since a battery and charge controller are not always available for leisure use, we have equipped our SolarBuddy with 2 USB ports for direct charging. The two connections are located on the handle and offer you direct connection options for your USB devices even without a charge controller and battery.
Robust and flexible:
The WATTSTUNDE® SolarBuddy Hardcover solar bag is both robust and space-saving, offering you a high degree of flexibility. The solar bag scores points with the option of being freely adjustable at any time. Whether behind the windshield while parked or outdoors, the deployable stand feet always help you find your optimal location.
The robust polyamide fabric makes the SolarBuddy your perfect companion for outdoor use - nevertheless, as with any technical device, care should be taken to ensure that no moisture or water gets to sensitive areas, such as under the cover of the USB ports. We recommend not leaving the SolarBuddy outside overnight. (This is an electrical device for using solar energy – that is, it does not tolerate steam or rain.)
Great power, light weight:
To increase flexibility, we have designed the SolarBuddy extra light. This makes it easy to set up and carry. However, we have not compromised on power.
Our SolarBuddy has a high efficiency of 18%. This allows you to charge your devices even in poorer lighting conditions. The monocrystalline solar modules are not only powerful, they also increase the service life. This means you can enjoy your mobile WATTSTUNDE® SolarBuddy for a long time.
Individual configuration:
Not only is the use (or free adjustability) of our SolarBuddy flexible - but also its connection options.
You can tailor your SolarBuddy exactly to your needs by choosing the charge controller and battery for storage that are right for you.

Tip: If words like charge controller and battery first bring up a question mark for you, you can contact one of our competent advisors at any time and find the optimal configuration for you together.
Follow the sun:
The free adjustability of the SolarBuddy allows it to be tracked with the sun to generate optimal yields at all times. Set at a 45° angle, it can also capture the last rays of the sun in spring and autumn, when conventional solar solutions produce only low currents due to the low sun position. Especially passenger cars with their small roof areas usually do not offer enough space for conventional solar panels; in exactly this case, a SolarBuddy is a real alternative to a solar bag.
Perfect for shade parkers and everyone who values flexibility.
Please note that no charge controller is included in the delivery of the SolarBuddy WS100SB. This is because in most cases charge controllers are already available, or customers wish to choose their own charge controller.
For example, we recommend the following MPPT controllers that fit the bag:
WATTSTUNDE® TARA Flow 75V 20A MPPT Solar Charge Controller
Votronic MPP 170 CI
Victron MPPT SmartSolar 75/10
