Cahill Renewables installed a large solar installation of 28 PVs and solar edge battery/inverter at my home. Initially recommended by a neighbour, they quickly drew up a draft design based on the google earth details of the house. They then arranged for an on-site survey which supported their initial design. At this stage they were able to finalise the estimate of cost to include the scaffolding and ground works. While not cheap, I considered the cost reasonable. During this stage of the process, they were very responsive to queries, and to carrying out (small) iterations of the specification. We agreed a date for installation. The day before installation their scaffolding contractors arrived, set up the scaffolding and the next day the installation team of 2 turned up. They worked solidly for two days, solving a number of unanticipated challenges along the way. They had a very professional 'can do' approach, and by the end of day 2 the installation was up and running. The following day some set-up was needed with the Solar Edge software, which the team at Cahilll did efficiently, making sure to communicate clearly what was happening. Two days later the scaffolding contractors returned to remove the scaffolding. Considering the size and complexity of the task, it was carried out with minimum of fuss, tidily and professionally. My electricity costs have dropped by over eighty percent in the three days since installation. Well done, Cahill team!
