Bunbury residential customers, it appears you also are stuck with Synergy like the rest of us. If you qualify for the Renewable Energy Buyback Scheme (REBS) you can receive 0.07c (7.1350 ex GST) for each unit (kWh) exported by your solar energy system. 

Eligibility criteria and full pricing, learn more >

The current installation lead time varies depending on what it is in particular you are wanting 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:

  • Inverter replacements: 1-week.
  • Solar PV install (built up Bunbury suburbs): 2-weeks.
  • Solar PV install (rural Bunbury regions): 3 to 4-weeks.
  • Battery install: 3 to 4-weeks.
  • Solar & Battery install: 3 to 4-weeks.

Western Power doesn’t allow single-phase solar inverter capacity higher than 5kW output. Synergy excludes solar inverter capacities which exceed 5kW output capacity from the Renewable Energy Buyback Scheme.

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

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