Paul was fantastic and explained in detail what was going on. Paul replaced 12x165w Panels removed and replaced with 13 new 250 watt panels and it is working like a charm. The first day after installation along with the saving in power used it returned 21 kwh to the grid. Absolutely fantastic
I would have no hesitation in recommending Paul and Green Spark Electrical.
