Adam was very knowledgeable and took me through all the steps and questions I had about various systems. He was able to give me a system that fit my needs and sized is accurately so I got good value for money (11 kW system with 8 kW inverter). The installation was smooth and the installers were professional, neat and polite. The after sales service I got was prompt and also professional. I have been recommending Replenishable Energy to friends since this positive experience.
