Zach Solutions GmbH

The short version is perfect!! From the initial quote and consultation to the final installation, I was completely satisfied! In total, I received seven different quotes – Zach Solutions was the only company with a detailed, clear, and easy-to-understand offer! Where there's work, there are bound to be some shavings – and here too, the cooperation was excellent! – Thank you!

From the initial consultation to the completed system, everything went smoothly. From the very first meeting, I felt that my wishes were taken seriously and that I would receive honest advice. The planning was explained clearly, there were no hidden costs, and the schedule was adhered to. The installation itself was very professional – the team was punctual, friendly, and worked cleanly. I was particularly impressed by the fact that even after installation, they took the time to answer my questions and explained everything about how to operate the system. Overall, I'm really satisfied: The system has been running perfectly since commissioning and even produces slightly more power than expected. I definitely recommend it!

We chose Zach Solutions GmbH because no one else explained everything to us so openly and thoroughly. My wife was thrilled; her quote, "Even I understood a lot of it," says a lot, considering she's not technically savvy. For your information, several companies were allowed to submit quotes. However, Mr. Nicolas Matjasic was the only one who listed every single item precisely on the quote, and consequently, on the invoice. He spent almost two hours explaining the quote and everything related to it (application, approval, subsidies, and even the electricity supply contract). After placing the order, it was only five weeks until construction began and two days for the installation. The installers were fantastic. Every company wishes they had such friendly, courteous, and hardworking employees. Problems with cable routing and space in the basement were professionally resolved, and the construction site was cleaned up very neatly. I can wholeheartedly recommend this company. And as for the price, it's absolutely fair.

I am extremely satisfied with the service and quality of work provided by this photovoltaic company in Graz! From the initial consultation to the commissioning of my system, everything went smoothly. The team was not only highly competent but also very friendly and helpful. Every question I had was answered thoroughly, and I felt very well taken care of throughout the entire process. The installation was carried out quickly and professionally, and the system has been running without any problems ever since. I was particularly impressed by the transparent communication and the after-sales support, which I found very pleasant. Thanks to this company, I can now not only produce my own electricity but also make a valuable contribution to environmental protection. I can wholeheartedly recommend this company!

Having had the pleasure of working with some of the management team in the past, I knew I wanted to give Zach Solutions a fair chance. Three installation appointments were needed instead of two because a defect was discovered during Zach Solutions' quality control check. This was communicated openly and rectified free of charge. Otherwise, the processing by the grid operator and the grant application was completed in record time, and I was able to feed electricity into the grid just two weeks after completion. We had a 12 kWp photovoltaic system and a 16 kWh storage system with automatic emergency power switching installed. I highly recommend this company.
