eight kW solar system value, efficiency and financial savings
* The repayment numbers may vary based on a number of factors and are an estimate based on a 5 year term. Terms of 3 to 7 years are available. Further information can be found here: Solar & Storage Finance
How much does an 8 kW solar system save me?
The potential savings from an 8 kW solar system depend on how much solar energy you can use in the household at the time it is generated.
As a rule, you save around 22 to 28 cents per kWh + GST for every kWh of solar energy consumed in the household (depending on how much you pay for your electricity).
Depending on your dealer, you will receive a feed-in tariff of around 5-12 cents per kWh for the electricity you send back to the power grid.
On that basis, you can save up to $ 700 to $ 850 per quarterly bill with an 8 kW solar system.

Number of solar panels for an 8 kW system
The larger the system, the more important it is to purchase high quality panels to ensure maximum reliability, higher performance in all weather conditions, and long system life.
The other consideration concerns the attic space. By installing highly efficient panels, we can use 22 x 370W panels instead of the standard 300W panels.
8 kW micro inverter system
Solaray is the largest and most experienced installer of Enphase Micro Inverter systems in NSW. Our system design team is expert in putting together a professional solar array that will maximize solar performance in all conditions.
The main advantage of microinverters is that each panel is independent from the others, which makes it possible to design an array through different orientations and at different angles. A common panel layout is with some panels facing north and the others facing west in order to distribute the power of solar energy throughout the day, making it easier to use more solar energy in its generation.
Panels West are also advantageous if you have a billing time for the period of use where households usually pay around 50 cents per kWh for electricity between 2 p.m. and 8 p.m.
In larger residential systems, the panels in the center of the array can get quite hot in summer because the airflow under the panels is not optimal. If the panels get too hot, the performance can be reduced significantly. For this reason, we recommend using micro-inverter technology. In fact, over 80% of our customers now choose to install this technology.

8 kW solar system in a house with single-phase power supply
Under certain circumstances it is now possible to install a system with an output of more than 5 kW in a house with single phase power supply in NSW. Enphase solar systems now allow us to limit the amount of excess Solar energy that your system sends to the power grid. This means that you are no longer limited to a 5 kW solar system. Here are some options for a home with single-phase power We'd love to talk to you in more detail depending on your location and your specific needs:
1. We can install a single phase 5 kW string inverter with a 6.6 kW array of panels. A well-designed solar system can save you thousands of dollars and significantly increase performance by oversizing the panel array compared to the inverter. Find out more …
2. Revolutionary Enphase technology has fundamentally changed the game for single phase homes in NSW. Until recently we could only install a 5kW system. Thanks to the export restriction, we can now use an Enphase system and limit the number of systems excess Solar energy that is fed into the grid. In this way we can install a solar array up to 10 kW powered by Enphase.
