Appreciated the expert advice from Charles Zammit, plus very good and comprehensive quote, and most of all the installation was done within 2 weeks by excellent certified solar electricians. Charles personally supervised all aspects to ensure the process ran smoothly and on time. Price was very competitive and coupled with service from Charles and Issy from Eco Star Electrical made for a happy satisfied purchaser. The carbonTRACK installation enabled me to see clearly total electricity used, solar electricity generated, grid electricity used, solar electricity used and solar electricity exported. TOO EASY! At the moment 32% of my total electricity used was powered by my solar!!
