Jane Woodhouse
Isabeau provided a personal service that made me feel secure from the start. She took time to understand the specific requirements of my property and helped me understand how it all works... I'm no longer in the dark! A HUGE THANK YOU TO THE AWESOME TEAM.
Jaco Coetsee
The service from Isabeau and her team was absolutely stellar! Great communication and professional installation. They even fixed electrical faults that were caused by previous contractors. Could not have asked for a better company to do business with, the after sales service is nothing short of exemplary, she assisted in fine tuning the inverter after the installation. I would highly recommend them for your solar and back power needs. Reply
