I contacted 5 companies in 2015 enquiring about solar panels, I went with EEC only because the salesman was not being pushy and did not give me a load of "flannel" sales talk. The installation was smooth and professional but ultimately for me, the after sales is second to none and still is 2 years on. If they say they will call you at a certain time they do just that. My output is exceeding their estimates which is excellent and my last usage of electricity submitted to my provider was only 20 units, yes only 20 units for a 3bed house. I am saving money as well as earning at the same time. A win win for me. I would 100% recommend EEC.
