Winkel Photovoltaik GmbH

Winkel Photovoltaik GmbH – Systematic Advance Payment Fraud! €20,000 gone, half-finished system on the roof – this is organized rip-off! I'm an end customer and in the fall of 2025 I ordered a complete PV system with storage from Winkel Photovoltaik GmbH (total ~€38,000). The sales pitch was perfect: "Our own installers," "everything from a single source," "connected to the grid quickly in 6-8 weeks," "We'll take care of the subsidies and grid connection." I believed it – and transferred €20,000 in advance. Big mistake. What really happened – and this matches exactly what subcontractors, sup

I was very satisfied with the consultation and I would definitely recommend the system, which has been running flawlessly for about 5 months.

From planning to key handover, the process was absolutely professional. It's a pleasure to implement a photovoltaic system with this reputable company. As of now, all calculations and forecasts have come true and exceeded expectations. The payback and self-sufficiency calculations were implemented with ease, as far as I can currently tell. My system consists of a 10 kW storage unit, a 10 kWp photovoltaic system, and a wallbox with excess charging.

We are extremely satisfied with Winkel: the system was commissioned yesterday. The quality of the components seemed very good, and the installation of the modules, inverter, battery, and wallbox was quick and seamless – everything was excellent! I'm glad we chose Winkel over cheaper providers!

From the initial consultation to the on-site technical inspection and the installation/commissioning, simply top-notch service. Appointments were kept and communicated well in advance. Complete installation in two days with highly competent tradespeople. Absolutely recommendable.
