6.6 kW Solar Sytems



6.6 kW Solar Sytems

Typically, a 6.6kW solar system with a 5 kW inverter will produce enough solar energy to meet the needs of the ordinary Australian household. A 6.6 kW system in Melbourne produces up to 23.8 kWh per day, 

Normally, a 6.6 kW solar system of good quality costs $5,500 to $8,000. The pricing depends on numerous factors. Where you live affects the solar subsidy for a solar system of 6.6 kW, Victoria is sub-divided in to Zone 3 which provides a higher subsidy as compared to Zone 4 postcodes. The quality of the solar panels you purchase and the installer you hire will have the most impact on pricing. With Victoria’s most trusted retailer,, Incredible Solar and Energy Solutions,, you can be sure about grabbing  the best deal out there.

We describe the advantages of a 6.6 kW system over a 5 kW solar system in terms of cost below:

  • Most likely, a 5 kW inverter will suffice.
  • You are given a rebate for the extra 1.6 kW worth of solar panels.
  • Installing a larger system very slightly increases labour time.

Due to panel efficiency losses and the fact that certain network distributors restrict  the installation of inverters larger than 5 kW, a 6.6 kW system often comes with a 5 kW inverter.

Therefore, you won’t have to pay more for an inverter. The additional 1.6 kW of solar panels are still eligible for further federal incentive . Installing a 6.6 kW system is significantly less expensive than a 5 kW system. You only need to spend more on the solar panels and a few minor extra installation charges to get the higher system capacity.
