Extremely happy with both the installation and Friendly service from TCL. Unlike other companies, we were given both space and time, over others that called (hounded us) daily. Both David and Simon were as good as their word. The sale and installation went smoothly, and the installers did a great job of the installation, very tidy, ensuring we knew and agreed with the placement of both the panels, inverter and batteries. Due to a winter installation, the system was commissioned the next day and the Engineers ensured that the system was error-free, and our mobiles were able to monitor the system. The installation from agreement to install was just over two weeks, and we were never chased for payments. We decided on TCL as they were more local to us, but we were quoted more for fewer panels, in the end. We went for sixteen panels (in case we purchase a EV) and we plan to add a second battery already too. in all, on fair to bright winter days, we have gone from using £5 per day, down to about a pound!!!! (the system should pay for itself within 5 to six years.) WE'RE VERY VERY HAPPY. THANKS GUYS.
