Happy customer Nellie McKay Review in regards to PSW vs The REst

Thank goodness for PSW. After 2 months of disappointments from other Solar companies who just didn’t want to know us when we needed to upgrade our consumer line to enable our 6.5kW system – “come back when its all ready to have your solar installed”. PSW just took the bull by the horns and ran with it – making the necessary contacts with Western Power and co-ordinated them to come out in conjunction with our PV install. The install team were so pleasant and more to the point efficient – nothing was too hard for them. Penny-Lee your professionalism and efficiency were exemplary in all the organizing with Western Power -even calling me up at 8 pm at night to keep me informed of progress – thanks so much. Derek your guidance in the type of system perfect for us was much appreciated. All this and at a great price too. Hats off to you all at PSW – keep up the good work. We now watch our smart meter via our portal just pumping out the power.
