Solar Power for your Home

With more than 20 years in this industry, Solar Power Australia make setting up your home with grid feed solar power easy.

We manage the process and will work with you to ensure you have the right sized system for your household requirements.

Solar Energy Production

A grid feed solar system produces power that offsets usage within the house to reduce your total power consumption. It also feeds excess power back to the grid and you receive a credit towards your usage.

Solar Power Australia can examine your recent energy bills and design and install a quality solar power system that is matched to your energy usage patterns.

The most popular size solar power systems for an “average house” these are between 5kW and 8kW. These systems can save a good portion of your energy bill and, if correctly matched to your energy consumption, can achieve an investment payback time in as little as 3 to 5 years.

SunPower Performance Panels are the most deployed shingled solar panel in the world. Innovative cell shingling mitigates the leading reliability challenges associated with conventional front contact panels by designing out fragile ribbons and solder bonds on the cells. SunPower stands behind its panels with its industry-leading Complete Confidence Warranty.


Solar Panels are a long term investment for any property. High performance solar panels use the latest technology to reduce losses from soiling and shading. A small percentage loss might not mean much initially, but over the 25 year life of a solar panel that means extra power production and more benefit to you.
