We are very pleased with our decision to get our solar system from PSW.
The whole installation process was quick and painless and has been working perfectly all year. We run ducted reverse cycle air con and I used to have a standing order with Synergy for $150 a month, this has been reduced to $20 a month and covers our bills. So approx savings are $1560 per year which means the payback period for the system is less than 3 years for us. I would love to get a battery for the system when the prices come down in the future.

A very easy and stress-free experience. Once I contacted PSW the whole process ran smoothly. There was no pressure to sign-up, all relevant information was sent to me and I was left to make my decision. The date was booked in and the system was installed without any issues. My roof faces East-West but PSW were able to install the system to still make full use of the conditions. Started producing power immediately. Have already recommended PSW to friends and will continue to do so.

3 kW solar inverters are often more cost-effective and in greater abundance than 4 kW solar inverters.
In addition, as solar panels often rarely reach peak-rated power, many reputable inverter manufacturers state that their inverters can be overloaded by up to 50% of the nominated input capacity.
The Clean Energy Regulator has had its say on this topic and capped oversizing to 33%.
Therefore, 3 kW Inverter capacity x 1.33 = 3.9 kW of solar panels and adding one more solar panel will exceed this limit.

This depends on you. A 3.9 kW solar energy system with a 3 kW inverter will generate an annual average 15 units (kWh) per day.
However, each dwellings consumption profile is unique, as unique as your finger print.
Sales support can provide detailed bill reduction estimates based on your past energy usage patterns. By using advanced software, the more past power bills you provide the more accurate your bill reduction estimate is likely to be.
Yes. However, as with all 3 kW solar systems, battery choices are limited. For example, if the only battery you want to install in the future is a Tesla Powerwall (AC coupled), then selecting any standard inverter will work.
Although, should your preference be a Sungrow SBR (DC coupled), a hybrid Sungrow solar and battery inverter, the such as the Sungrow RS HS inverter.
Eligible Perth and Bunbury region customers within STC Zone 3 receive a $1569 point of sale discount (subsidy) when installing 3.7 kW of solar panels on a 3 kW inverter.
Based on 38 claimable Small Technology Certificates, a system incorporating 9 x 440 W solar panels and a $38 STC market value.
38 STC’s x $38 value = $1456 subsidy.
For your convenience, the Perth Solar Warehouse 3.7 kW solar package prices include the subsidy already deducted as a point of sale discount (redeemable by Perth Solar Warehouse after installation).

Most residential 3.7 kW solar arrays installed on a 3 kW inverter will qualify for the Synergy’s solar Feed-in Tariff named; DEBS (Distributed Energy Buyback Scheme).
This means you can receive 0.025c ex GST during off-peak and 0.10c ex GST during peak periods (3pm to 9pm) for each unit (kWh) exported to the grid by your solar energy system.
