Testimonials

What our clients say!

I had Joule install a solar system with battery and a charging station for my car, and it all worked out great. They advised me very well, were very reactive, I was informed about every step of the construction site, and the team worked very cleanly and professionally. They always left a clean job site, were always reachable and gave immediate feedback. The price-performance ratio is also top, what more could you want? I can advise anyone who wants to install a solar system: Go to them! They are extremely competent, flexible, professional and extremely nice.

Great service and top quality. Thank you again.

I am very satisfied with the photovoltaic installation for my balcony. The advisor, Mr. Mourad, was extremely competent and clearly mastered his field. He took the time to carefully listen to my needs and provided solutions that were well suited. When a small issue came up, he reacted quickly and efficiently to resolve it. The service was professional from start to finish. I highly recommend it!

We are very satisfied with the installation as well as the professionalism of your team.
