"I used the services of InvertSum on the recommendation of friends, although I also considered other options. And it was a bull's-eye! The guys at InvertSum advised me step-by-step on how to complete all the work and modifications to the carport. The result is fantastic – everything works as it should. A company worth recommending – reliable and professional at every stage."
A little over two years ago, the company installed a PV system for me, and now they're doing an additional 4 panels. Everything was as agreed, and the installation is running smoothly. The service is excellent, efficient, and professional. I wholeheartedly recommend Maciek and his team.
I decided on ground-mounted photovoltaic panels, and after six months of use, I believe it was a bull's-eye. The solid construction and steel supports gave me confidence in the best way to position the solar panels, ensuring high efficiency for the entire ground-mounted installation. My electricity bills have dropped by as much as 90%, which I'm most pleased with. All formalities were handled by the company, and the work was completed quickly and efficiently. I wholeheartedly recommend INVERTSUN for their professional, reliable service and complete professionalism. Mariusz - Lesser Poland Voivodeship owners of a single-family home
Amidst a sea of phone calls and various offers, I decided on PV installation. I chose Invertsun on the recommendation of friends who had installed solar panels for some time (in the Lublin area). Excellent customer service before, during, and after the project. Excellent communication, very good prices, and above all, the entire team has extensive knowledge and capabilities. Installation in the northern part of the Lublin province, east-west. I highly recommend and best regards!
I can 100% recommend Invertsun. Everything was done to a very high standard. They provided expert advice on selecting the optimal installation. I received answers to every question that dispelled all my doubts. The installation itself was seamless, performed precisely and carefully, with attention to the smallest details. They took care of all the formalities for me, which is a huge plus. The equipment they installed is of very good quality, and I'm confident that everything will function as it should. After signing the contract, everything went very quickly, and I can now enjoy my own electricity.
