PLUTA attorney Florian Zistler keeps solar energy system supplier Sungrade operational

Günzburg-based Sungrade Photovoltaik GmbH has filed for insolvency. Following this, on 2 October 2025, the Local Court of Neu-Ulm ordered provisional insolvency administration for the company’s assets and appointed Mr Florian Zistler from PLUTA Rechtsanwalts GmbH as provisional administrator.

The regional supplier of solar energy systems remains fully operational, and existing orders are being fulfilled. The salaries of the 26 employees are guaranteed for a period of three months thanks to specific substitute benefits provided under German insolvency law. The company is facing significant challenges that have affected the entire photovoltaics industry in recent years, including material and supplier issues, increasing price pressure and fluctuating market conditions. These factors have ultimately led to liquidity problems.

Provisional insolvency administrator Mr Florian Zistler from PLUTA said, “We are in the process of gaining an overview of the company’s position. I have already held discussions with the relevant people and informed the employees about the situation. Our goal is to preserve the business, and we will examine all options available for this.” The administrator is being supported in the proceedings by business lawyer Mr Dennis Stroh. The PLUTA team will hold discussions with potential investors over the coming weeks.

Both managing directors, Mr Stefan Sommerer-Wagner and Mr Ralf Prestin, said, “We did not take the decision to file for insolvency lightly, but we were left with no alternative. We hope it will be possible to find a sustainable solution.”
