Assuming you are looking for a tier 1 panel and inverter, the approximate price guidelines in 2019 are:
- 3KW: $3,500- $5,000
- 5KW: $5,000- $9,000
- 10KW: $10,000- $14,000
Please note these prices are the price you pay after the rebate has been added to the cost of the system. The lower end are a more standard system and the upper end are a very high end system.
These costs can increase if your home or business needs upgrades to the switchboard or other areas of the property to allow solar to be installed. If you decide to go with micro-inverters or add batteries, the cost of the system would also be higher.
Be mindful that cheaper isn’t better with solar. If you are getting prices below this guideline, beware of the corners the installers may cut, or the low quality parts they are installing on your property.
