I can thoroughly recommend K.Cahill who installed our 6.8kw solar system with 6.5kwh battery. We moved into our new house a few months ago and got 4 quotes from a couple of local suppliers and a couple of national providers. K.Cahill were not the cheapest but suggested a good system, have a strong background as electricians and George in the office was able to answer all of my many queries. Initially we agreed on 14 panels being installed on the SSE and WSW facing roofs, with additional panels being added at an agreed rate each should more fit. On the first install day Keiren, Kem and Jermaine attended to do the install. They were able to fit 14 panels and install the battery and inverter over the course of the long day. They were able to position them better than I had expected with micro inverters on all of the panels which might be shaded over the course of the average day. Kem followed up for a second visit to fit 5 additional panels in positions agreed on the first install date. Keiren got the system connected to the internet and set up the mobile app for me so that I can see how the panels are performing and showed me how to best control the system with advice on maximum effectiveness. All ran very smoothly and I'm delighted with the performance of the system as well as the placement and look of the panels. From their and my own research, as well as the rapidly increasing energy prices, it should pay for itself within 10 years, after which time it's all profit. I can and will thoroughly recommend K.Cahill and his team for anyone interested in a solar system.
