⭐⭐⭐⭐⭐ We are extremely satisfied with our photovoltaic system and the entire process handled by Helios 365. From the very beginning, Mr. Leonhartsberger provided us with expert, honest, and completely satisfactory advice. We received a very fair offer and felt exceptionally well taken care of throughout the entire project. Even after Mr. Leonhartsberger left the company, we continued to receive friendly, prompt, and competent support from the back office and the other Helios 365 employees. All our questions were answered reliably, and the subsequent processing went smoothly. We have absolutely nothing negative to report and are very happy with the purchase of our photovoltaic system and the overall service. Therefore, we can wholeheartedly recommend Helios 365. Many thanks to the entire team!
We had a PV fence installed and are very satisfied with the company Helios; they were friendly, competent, punctual, and the price-performance ratio was very good.
We had a storage system retrofitted to our photovoltaic system. Dominik Leonhartsberger's consultation was excellent, and he answered all our questions thoroughly. The installation was quick and professional. We will definitely use Helios again for future expansions because we were very satisfied with the entire process and highly recommend them.
Dear Helios 365 Team, Thank you in advance for the quick and uncomplicated service. I was greeted with a genuine smile at reception and immediately directed to the right person. Everything was perfect, from placing the order to picking it up. Keep up the good work, thank you and best regards!
Shopping and pickup now works perfectly (simple, fast, and hassle-free). About two years ago, this wasn't quite so straightforward with HELIOS 365. The price-performance ratio has always been good with HELIOS 365.
