12 months post install of 24 panels fitted front and back and 12.5Kw of battery storage I have had no problems whatsoever with the project, and have generated just over 6Mw of energy, either to be used in the house to drive the Air Source Heat Pump and other fittings or offload to the grid (for a measly 4.5ppKwH). I left it 12 months to review so I had a full year to assimilate the benefits. My total energy bill divided over 12 months averaged out at £79 p/m. Higher in winter due to the ASHP keeping us warm but next to nothing in summer. I like many others had investigated numerous solar companies to gain knowledge and real quotes - there are cowboys out there - and Simon came up with the goods not only in underpinning knowledge but non aggressive selling - in the end my decision. I am glad I decided to use TCL they operate holistically and have great service from first contact to completion. The install was carried out in 1 day by extremely professional fitters who took time to explain and demonstrate the system. I even took the opportunity to clean my gutters whilst the scaffolding was erected. Can't recommend these guys enough, and have done so verbally to others throughout the year. Best of luck in the future David and Simon, I am sure you will have no trouble in the current economic environment of growing your business exponentially through complimentary word of mouth recommendations. Thanks. Ben
