Very satisfied with the installation of our charging station and solar panels! The installers were incredibly skilled and worked neatly and professionally. Everything was clearly explained, and they were very helpful in finding the best solution for our situation. The back office also deserves a compliment: friendly, easily accessible, and always willing to help. The materials are high-quality, and the entire installation was carried out in close consultation. Agreements were kept, and the end result is exactly what we had hoped for.

The Vannisa team did a great job within a reasonable timeframe. They were very polite and worked professionally. They were also easy to reach for questions. All in all, I'm very satisfied.

My solar panels stopped working due to a defect in the inverter. The supplier of the panels at the time went bankrupt, so I ended up with Vannisa. Huge compliments, easy to reach, and they're always willing to help find solutions. The technicians who came to fix the problem were incredibly friendly and professional. I'm glad I discovered this company. Thankfully, my panels are working again ☀️ Very satisfied 👌🏼

The fantastic company Vannisa made our farmhouse and guesthouse completely gas-free. We now have solar panels, air conditioners, heat storage tanks, heat pump boilers, etc. to keep everything warm. The existing radiators are even connected. We were fully supported from start to finish, provided with ideas, input, and the execution of this massive project. Ultimately, the price was even better than the quote. Mr. Bor's communication is excellent, promises are kept, and the execution went perfectly. We can only say that this company has nothing but experts who think along with us and work extremely socially, carrying out everything in consultation with the client. They are even willing to help, right up to the subsidy application stage. We extend a deep bow to Mr. H. Bor. Thank you very much for everything! Auke & Lineke
