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.

The current installation wait time varies depending on what it is, in particular, you are wanting to be installed. Why is this? Quite often it’s related to engineering assessments by Western Power.

Below is a breakdown of the average lead times for the following PSW services within the Yanchep and Alkimos region:

  • Inverter replacements: within 1-week.
  • Solar PV install: within 4-weeks (peak period 8-weeks).

PSW is a registered electrical business in Western Australia. As a McKercher Corporation Pty Ltd business (EC010771) PSW utilises an in-house electrical service team insured and licensed to perform electrical services on your property within the greater Northam and York area.


PSW supplies fully installed products only direct to Northam and York region end-users.

Western Power doesn’t allow single-phase solar inverter capacity greater than 5kW output to be connected to the grid. Synergy excludes solar inverter capacities which exceed 5kW output capacity from the Distributed Energy Buyback Scheme on the Northam and York region grid.

As solar panels rarely reach peak rated power, certain solar inverter manufacturers state that their inverters can be overloaded by up to 50%.

However, the Clean Energy Regulator has had their say on this topic and capped oversizing to 33%. Therefore, 5kW Inverter capacity x 1.33 = 6.6kW of solar panels.

Very happy with my PSW Solar system. Derek was very knowledgeable & helpful with all my queries. Moly, Penny-Lee and all the other office staff were always quick to respond to emails & phone calls. Most importantly now the weather is heating up my savings are increasing, my last bill was practically just a supply charge with less than $10 for power consumption. Have already recommended PSW to others and will continue to do so. Thanks!!
