The first combined battery pack is now with a satisfied customer. More than 40 kWh can be stored, so the green energy cannot be lost. In this way, we not only help companies, but also individuals with a successful energy transition!
After installing 70 solar panels, the desire arose to store the energy gained. Logical, because the sun does not always shine in our beautiful little country. In addition, it is also sustainable and saves our customer a nice amount of money in the long run.
By means of a mobile app, our customer can see, monitor and manage the exact behavior of his energy generation installation. Handy, right?! The installation was installed and handed over to the customer in no time. On to the next one!
The advantages of this solution:
After the first success, we got the hang of it. Are you also interested in a home battery? Contact us or drop by. We are happy to help you find the best solution!
In 1920, Jan Cornelis van der Leun opened his shop at the harbor of Sliedrecht. Radios and electric lighting were still new and remarkable at the time. What began with providing light and sound soon grew into creating solutions for the shipping industry and the emerging dredging sector.
That hands-on, problem-solving mentality is still at the heart of our work today.
Stores are constantly evolving: new concepts, updated interiors and smarter technologies. But who makes sure all those plans are actually carried out behind the scenes?
In 2025, Royal van der Leun is responsible for the maintenance and renovation of over 500,000 m² of retail space across the Netherlands. A task that goes far beyond simply pulling new cables.
From June 24 to 26, 2025, Royal Van der Leun will be present at the Electric & Hybrid Marine Expo Europe at RAI Amsterdam. At this leading trade fair in the maritime sector, we will showcase our latest solutions in intelligent electrical systems and sustainable innovation.
