Understanding Your Solar System Estimate
Your results from the solar calculator provide a breakdown of how many panels you’ll need, your estimated solar costs, and your annual energy savings. The calculator analyses your average electricity bill, electricity usage (in kWh), and local sunshine conditions to recommend the best system size for your roof. It also factors in any feed in tariff your electricity retailer pays when excess energy is sent back to the grid.
Each calculation considers important factors like roof area, shading, and inverter efficiency to ensure you receive a realistic system estimate. For most Perth households, a solar system between 6.6kW and 10kW offers excellent balance between upfront cost and long-term savings.
How Our Solar Calculator Works
This smart meter–enabled solar calculator uses real-world electricity data and Australian Government rebate values to determine the total cost of your solar power system. Simply input your energy details, such as monthly electricity use and cost per kWh, and the calculator instantly estimates your solar savings, payback period, and system cost. Our calculations are based on average Perth solar output, standard installation conditions, and Tier 1 solar panels from leading solar retailers.
Example Calculation
For example, if your household uses 900kWh per month with an average electricity cost of $0.32 per kWh, a 6.6kW solar system could reduce your electricity bill by up to 70%. With current feed in tariff rates and government rebates, most homeowners can expect a payback period between 3.5 and 5 years. The system’s total cost varies depending on the inverter type, roof orientation, and installation details.
