WATT do our customers say?
As the owner of a T6.1, I finally found the solution that lets me work with peace of mind while travelling. A huge thank you to NatureWatt for the quality of this 450 W kit. The installation is accessible to everyone, the explanations are crystal clear, and the after-sales support provided by Andreas is exceptional. You can really feel the passion and expertise behind it. This is an investment I absolutely do not regret — the freedom is complete and the quality is more than impressive :)

NatureWatt Core 450 Wp
Amazing service! I ordered the NatureWatt 450 W Beach set and I’m genuinely impressed. Two modules were sent to me in advance by express delivery so I could get going right away — really strong service! The final module then arrived later without any hassle, even with a small gift included (see photo). Communication was super relaxed, friendly and straightforward. As soon as the weather allows, the last module will be installed 👌 This is exactly how it should be — clear recommendation 👍

NatureWatt Core 450 Wp
The product is very well designed. It is equipped with special brackets and cables for the California. When I tested it after installation, I saw that it was truly effective. It has a much more aesthetic and stylish appearance than systems produced for the California by other companies. I am very happy that I chose this product. We would like to thank the founders, Andreas and Christoph, for their attentiveness and support.

NatureWatt Core 300 Wp
At NatureWatt, you find customer service exactly the way you would hope for it! It started with friendly and uncomplicated communication, followed by individual consultation and an installation that could be adapted to my VW bus. All materials are very high-quality, beautifully shaped, precisely fitting, well thought out and assembled by hand. The surface finish of the visible support parts is also simply excellent. I was particularly impressed by the modular design of the system, which allows the solar modules to be removed from the roof again if needed. The connector of the connection cable remains on a small mounting plate on the roof and can be sealed watertight. All in all, a very well thought-out solar system that is worth its price!

NatureWatt Core 150 Wp
After the first week on the road with the van and solar setup, I’m incredibly happy! The quality is outstanding and it looks so great. The solar panel power is more than enough! I looked into several other companies offering solar panels, and I’m so glad I chose NatureWatt. In my opinion, it’s the best option on the market if you truly love your California — and probably the only one with a plug-and-play option for adding more panels without needing to rewire anything. Christoph is also very helpful and always willing to answer any questions you might have.

NatureWatt Core 300 Wp
Since installing the set with two modules, we have been completely self-sufficient and independent while travelling with our VW T6.1 California. Delivery was ultra-fast and the installation was completed in 60 minutes — the instructions and pre-assembly were excellent. Even in cloudy weather, the system reliably supplies power for the fridge, lights & more. On sunny days, the battery is fully charged in no time. Great support, first-class quality — a clear recommendation!

I am extremely satisfied with the NatureWatt Core set for my VW T6 California Ocean! Everything feels incredibly professional and well thought out. All cables inside the vehicle are completely hidden and the charge controller sits perfectly in the cabinet thanks to the dedicated mount. The personal connection with the founders was a real highlight — always helpful, friendly and ready to provide advice and support. An absolutely top experience!
