I was looking for an installer to extend my existing home solar system in Ilpendam with more panels. I already had 9kWp SolarEdge system and wanted to add 5kWp more to the same inverter. At some point I called Harrems Zonnepanelen, and was pleasantly surprised by a personal approach. We discussed my technical wishes (I installed solar panels myself in the past) with Frederik and he was very flexible, unlike many other companies I called before! He's agreed to work on my project using my measurements of the roof and the panels I bought (12 x First Choice Solar 410Wp having very non-standard size 1889x1035mm) which allowed us to cover my roof as optimally as possible in terms of total power - exactly what I wanted. The installers came on time and were working fast, safely and friendly to my suggestions or help. Needless to say it was also very convenient for me to communicate in English during the whole process, from initial phone contact till the final pleasant pairing of optimizers :) I can definitely recommend Harrems Zonnepanelen, esp. if you need flexible custom approach to your project and requirements.
