Last week we received 10 solar panels and a hybrid heat pump. We're very happy with them; the guys installed them very professionally. Everything was neatly concealed. They provide excellent service. Thanks, guys.

Delivered and installed within three weeks. Contact was super fast. Both via WhatsApp and phone. The installers are very neat and tidy. Cables are neatly concealed. (They even went through the crawl space.) The panels are even better positioned on-site due to their favorable location. I definitely recommend Zonneprofijt.

Today, 9 solar panels were installed at my place. The quote request went smoothly, and I received the quote the next day. The work was carried out neatly, efficiently, and safely. Scaffolding was erected quickly, and halfway through, the craftsmen were, of course, provided with delicious sandwiches. I received a clear explanation and immediately signed up for net metering and installed the app, and within minutes, I had a clear understanding of the system. Highly recommended…

After much research and comparing several offers, Zonneprofijt placed the order to supply and install 32 solar panels. Following an on-site inspection, the installation was quickly scheduled. On the agreed-upon day, the panels were neatly installed, and by 4:00 PM, the system was operational, including monitoring via the app. Zonneprofijt also arranged supplier registration with Liander and VAT refunds. Highly recommended! (32 x Solarwatt 360 + Solaredge 3-phase inverter).

My friends recommended WattSlimmer for a heat pump, heat pump boiler, and solar panels. From the very first contact, I received a quick response and honest advice, as well as a competitive price. Because a higher subsidy was available in 2024, they were very helpful, and the entire installation was completed that same year. The installation was carried out very professionally, and all agreements were honored. There were a few minor surprises, but these were resolved quickly and efficiently. They are very flexible and truly live by their motto: "say what you do and do what you say." What sets WattSlimmer apart is their attention to detail and the way they coordinate everything perfectly. That, for me, is the true added value of this company. I would therefore always recommend them to anyone in my immediate circle (which I have already done twice).
