The average Gold Coast household pays over $800 a quarter just to keep the ducted aircon running. A custom-designed solar system stops the bleeding — but only if it's sized right and the company sticks around.

Disclaimer: These figures are indicative estimates only and are not a guarantee of savings or system performance. Calculations assume a 5% compound annual increase in electricity prices, a solar and battery system offsetting approximately 78% of grid consumption, and are based on your stated quarterly bill. Actual savings will vary depending on your roof orientation, shading, household usage patterns, system size, feed-in tariff rates, and local network conditions. This calculator does not constitute financial advice. A Precision Energy Design audit by a qualified SEG energy consultant is required to provide an accurate, site-specific assessment for your home.
The Gold Coast Problem
Thousands of Gold Coast homeowners chased the cheapest quote from a company that disappeared. Their systems underperform, their warranties are worthless, and nobody answers the phone when something goes wrong.
Wrong-sized systems
Cookie-cutter 6.6kW quotes don't account for your pool pump, ducted AC, or actual usage patterns.
Orphaned warranties
When the installer disappears, your 25-year panel warranty becomes a piece of paper with no one to call.
Missed rebates
Most homeowners leave thousands on the table because their installer didn't handle the paperwork properly.
