Verified reviews from EcoRay customers.
"We had a really good experience buying and installing our new solar system. From the very first contact we met an open dialogue and a highly professional approach. Every question was answered quickly and the installation went exactly as agreed. Based on our own experience we can safely recommend EcoRay to anyone considering solar."

"Nothing less than FANTASTIC from start to finish. I can always call Nicolaj and Patrick if I have questions - both extremely competent. We've been self-sufficient on electricity since the system went live, and it's a joy. The system is completely silent, so nobody is disturbed."

"I chose EcoRay out of a great many suppliers on the Danish solar market. My choice came down to a genuinely pleasant and professional advisor, Vitus, who listened and understood that I had some special requirements. I can warmly recommend EcoRay."

"Buying solar is like landing in a maze of hungry salespeople, but I found my way out by trusting my gut. Every agreement was kept to the letter, it took under 3 weeks from signing until everything was installed, and now it saves me money every month. Would I choose ECORAY again? Without a doubt."

"Super fast once everything is in place - about two weeks later it was up and running."

"Only good experiences with EcoRay, from the very first contact before the sale to the installation, which went incredibly fast - just a month after buying we were already saving. With electric heating and two EVs we went from a normal May bill of 1,500 kr. to just 60 kr. Nothing but a recommendation from us."

"Kind and very friendly young men who were thorough in their preparation. It took only a few weeks from ordering my panels until they were on the roof, and I could follow along in an app. Nicolai and Patrick made me dare to invest that kind of money, and I felt safe the whole way. I can only send the warmest recommendations."

"Great service - they call and follow up on whether everything is as it should be. Easy to talk to and always reachable. A pleasant experience."

"I had a really good experience with EcoRay from start to finish buying and installing solar. They were great at explaining things, and their calculations were realistic - not just numbers thrown around like some of the others we talked to. Professional from start to finish, clearly recommended."

"EcoRay has handled the solar installation on our property from the start. They can be warmly recommended as a supplier, as can their service, reliability and communication. Their installers are friendly, helpful and highly professional, and the result is beautiful both on the roof and technically."

"A really pleasant experience and great conversations with EcoRay! I especially want to highlight William and his passion for the subject, and for helping us find the right solution. He is very focused on the customer and what is right for you."

"We had been considering solar for a long time, and after honest and pleasant conversations with William from EcoRay we've now moved ahead. The complete solution and the expected savings appealed to us, and with those clear explanations it was genuinely hard not to go with them. A very professional setup."

"A very professional and strong team at EcoRay. You can safely buy your solar system from them. I especially want to highlight Alexander, who is both passionate and a pleasure to talk to. The service is top notch and you feel truly safe and in good hands. You can't go wrong with EcoRay - that's 100% certain."

"The advisors were kind and good at guiding me through the process, so I got a sense of both the technical and the financial side. And not least I got a good price. Clearly recommended."

"Getting solar on the roof has been a completely perfect experience. Everything just worked - installers on time, beautiful work, kind and friendly. It has been a fantastic experience and can be 100% recommended."

"I had a really good experience with EcoRay from start to finish buying and installing solar. They were great at explaining things and their calculations were realistic. Professional from start to finish - clearly recommended."

"A really good and constructive dialogue about a system for our summer house. Lovely transparency throughout the conversation, and their calculator gives a clear overview of consumption and potential savings."

"I've had a really good experience with EcoRay. They are competent, friendly, and the service definitely lived up to my expectations."

"Really good service, no hidden agendas. If I had questions I was only a phone call away from getting answers to all of them. I thought that was fantastic!"

"We had a really good experience right from the start - good information about the product, and Patrick, the advisor, was very welcoming and understanding. The installation went as planned and the system has worked excellently from day one. Nicolai, who handled the installation, was also a great help in understanding the system. All in all we are very satisfied."
