We had the opportunity to work with Voltamper in more than 20MW solar projects in UK and more than 25MW in Turkey. They completed with responsibility and excellent professionalism the assigned works even in difficult conditions. I can easily recommend Voltamper as subcontrcutors for similar projects.

Having worked with Voltamper, owned by Mr. Karakasidis and Mr. Tosnaridis, since 2012 I can only think positive. Throughout these years we have been cooperating in the field of electrical installation on solar power plants, with excellent results. Always willing to work hard and try to make the best out of every opportunity. Somehow they manage to turn negative events into positive learning experiences and improve further every time. Reliability, responsibility, professionalism and efficiency are only few of the words that could describe their character as individuals as well as their professional attitude. I am pretty confident that they will be a great match for any relevant cooperation and I highly recommend them.
