Fantastic service from start to finish. The installation team were friendly, tidy and very professional. So impressed with the system installed and the Tesla battery - the app clearly shows all that is happening with our system.

Frequent questions: 6.6 kW solar

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

Most leading inverter brands state that their inverters can endure solar array oversizing up to 50%. The Clean Energy Regulator has had its say on this topic and capped the oversizing of solar inverters to 33%.

Therefore, 5 kW Inverter capacity x 1.33 = 6.6 kW of solar panels.

Internal post: Oversizing Solar Arrays on Inverters Increases Savings Potential ›

This depends on you. A 6.6 kW solar energy system with a 5 kW inverter will generate an annual average 30 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 6.6 kW solar systems, everywhere, 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 (solar only) inverter will work.

Although, should your preference be a Goodwe Lynx Home F (DC coupled), a compatible hybrid solar and battery inverter such as the Goodwe EH+ inverter is required.

Eligible Perth and Bunbury region customers within STC Zone 3 (2024) receive a $2426 point of sale discount (subsidy) when installing 6.6 kW of solar panels on a 5 kW inverter.

Based on 64 claimable Small Technology Certificates, a system incorporating 15 x 440 W solar panels and a $38 STC market value.

64 STC’s x $38 value = $2426 subsidy.

For your convenience, the Perth Solar Warehouse 6.6 kW solar package prices include the subsidy already deducted as a point of sale discount (redeemable by Perth Solar Warehouse after installation).

Most residential 6.6 kW solar arrays installed on a 5 kW inverter will qualify for the Synergy solar feed-in tariff named; DEBS (Distributed Energy Buyback Scheme).
 
This means you can receive 2.25c ex GST during off-peak and 10c ex GST during peak periods (3pm to 9pm) for each unit (kWh) exported to the grid by your solar energy system.
