Solar panels with
heart for service

Enjoy renewable energy all year round with solar panels from De Duurzame Jongens, which provide long-term value.

Solar panels maintenance

De Duurzame Jongens are excelers in service. Because we stand for quality. And going the extra mile for our customers. In fact, we will visit you once a year for maintenance of your system, preferably in the spring. Because dirt on your solar panels leads to lower yields. And that, of course, cannot be the intention! In addition, we immediately do a safety inspection according to SCIOS SCOPE 12. Then we will know immediately if the installation still meets the set requirements.

All-in service from De Duurzame Jongens

24 hours a day, 7 days a week

In addition to supplying and installing solar panels, we offer 24/7 service in the event of a breakdown or damage. This is how we distinguish ourselves as a niche entrepreneur from the big solar companies. In urgent cases, we are immediately available to fix the problem for you. 24 hours a day, 7 days a week. And all for a small amount of money each year!
