Different solar systems come at different prices. For instance, if you want to install a 5kWh solar system, you will pay about $4,450 inclusive of the rebate. The government rebate makes the solar systems affordable, while the incentives you receive from FiT providers incredibly reduce the panels’ payback time.

With a 5kWh system, you will be awarded a rebate of approximately $2,870. This means you will buy the system at a much lower cost than when the rebate is not applied. Below is a table showing the prices of different solar systems.

The number of panels you need to power your home depends on your house’s size, the physical space on your home’s roof, and your power consumption. The number of people in your home also determines the number of panels you will install.

To know the exact number of panels you will need, you should multiply your household’s hourly energy requirement by the peak sunlight hours. You should then divide the results by the wattage of the panel to know how many are enough for your home.

Yes, you can, but the maximum limit is 33%, according to the CEC Solar PV Design Guidelines. Beyond this limit, government rebates will not apply. When oversizing your system, ensure you use high-quality inverters, and your system must be installed by a professional installer who is CEC accredited.

Yes, battery storage is paramount to make sure you store the excess energy produced during the long summer months. With enough power, you can go off-grid and have enough power to sustain your home during the freezing winter weather.

The industry standard lifetime of solar panels is approximately 25-30 years. Ideally, solar panels reduce about 10% of their efficiency during the first 10 years.
