SunStrom GmbH

After our SMA inverter (installed in November 2012) failed, a replacement with an SMA hybrid inverter and battery storage was installed in October to our complete satisfaction. We were particularly pleased with the excellent communication, both by phone and in person, with the customer service, sales, and project implementation teams. The professional work done by the installers on site was also outstanding. 5 stars *****

Everyone at Sunstrom we dealt with, from the initial consultation and planning stages to the final implementation, consistently considered our wishes, acted attentively, and were reliable contacts. All deadlines and agreements were met, and what's more, the construction site was always tidy and barely affected our comfort at home. This is far from being a given. Therefore, we will gladly and wholeheartedly recommend your company at any time. Many thanks to all your colleagues!

We recently had a photovoltaic system with battery storage and a wallbox installed by Sunstrom. The coordination, adherence to deadlines, utility company registration, and project management were all reliable and highly professional. Thank you again – we will gladly contact you again if needed. Highly recommended!

A 9.5 kWp solar system was installed on my roof by Sunstrom in early February 2024. From the initial contact in August 2023, through the signing of the contract in early October, to the installation, only six months passed. The collaboration and implementation went exceptionally well. At my request, high-quality glass-glass modules manufactured in Germany were installed. Both the rooftop installers and the electrical technicians were competent and worked efficiently. The stringent safety requirements (scaffolding is mandatory) are also commendable, unlike those of some budget providers. All in

Many thanks to the entire SunStrom team. I had a large solar system installed and I can only commend the excellent communication and practical work. There were absolutely no problems with the scheduling or the system's operation. The initial consultation was a great foundation, and the service also included handling all the registration formalities. Thank you – and I wish you many more satisfied customers.
