After the purchase of an electric vehicle and anticipating the forthcoming hike in energy bills I researched some options for self generation of electricity. After talking to a plethora of people, receiving several quotations and taking into account recommendations, one company stood out for me .. Cuberoot. I avoided the trap of going for the cheapest quote and in my opinon I ended up with the most professional outfit. Bob and Mark were happy to answer all my questions and I agreed to go ahead with the installation of a 4.8kW solar array and a Tesla Powerwall 2. I'm extremely happy with the professional and solid installation job that they did, especially in retaining the integrity of my roof tiles. They also made a great job of concealing cables under block paving. I've immediately seen a significant impact on my energy bills, even without having yet gone through a full summer. After sales support (mainly questions) has also been great. Highly recommended.
