Customer reviews
They chose independence.
Clean installation. Our bills dropped by 65% and the monitoring app is super intuitive.
We paired solar with a heat pump. The Opus team was ultra-professional from A to Z.
The fact that they handle all the administrative subsidy paperwork tipped the scale. Perfect.
