I have waited 16months to write this review so that it is up to date and positive. I was really impressed with the high quality of service from everyone from first contact, survey and then installation. The follow up information was excellent and nothing was left out. Truly a professional company and I do not hesitate to recommend EEC Solar to anyone considering using their services. I was also happy with the price I paid. After a year my returns exceeded the estimate provided so I am more than happy. The Solar iBoost fitted to the immersion heater/tank diverted approx 1,000kWh of electricity during the year saving me the equivalent heat output of using oil. My payment for generated electricity was £490 and my normal electricity usage was approx 1,000kWh less than the previous year. Summing up I have to say that I am over the moon with my solar panels so a big thank you to all at EEC Solar. Graham Patrick
