Every Keystones system is sized against your actual electricity usage, roof orientation and shading — not a generic package. These are the sizes we install most often across the Sunshine Coast, from Caloundra through to Gympie.
| System size | Best suited to | Typical daily output |
|---|---|---|
| 5 kW | Units, townhouses and low-usage couples | ~20 kWh |
| 6.6 kW | The standard Sunshine Coast family home | ~26 kWh |
| 10 kW | Larger homes, pools, ducted air conditioning | ~40 kWh |
| 13 kW+ | High-usage homes, or homes adding a battery or EV | ~52 kWh |
| 30 kW – 1 MW | Commercial rooftops and light industrial sites | 120 kWh – 4 MWh |
Output figures assume 7.5 peak sun hours, the Sunshine Coast annual average. Actual generation depends on roof pitch, orientation and shading — all of which we measure during the free site visit.
We visit your property, inspect the roof and switchboard, and review 12 months of usage from your retailer so the system is sized on real consumption rather than a guess.
You receive a panel layout, inverter selection, expected annual generation and a fixed price with the federal STC rebate already deducted. No variable pricing on install day.
We lodge the Energex connection application and handle the paperwork. Most residential installs finish in one to two days, carried out by our own Clean Energy Council accredited installers — we do not subcontract.
We commission the system, set up monitoring on your phone and walk you through it. Every install carries a 10-year workmanship warranty backed by a local team you can actually call.
We install and support Sigenergy, Deye, BYD, Pylontech, Tesla and Sungrow battery systems, either alongside a new solar system or retrofitted to an existing one. With the federal battery rebate now in place, a 10–15 kWh battery is viable for most Sunshine Coast households that already have solar.
See our battery and off-grid systemsWe service systems we did not install. Common Sunshine Coast jobs include inverter faults and error codes, isolator and DC cabling failures, panel replacement after storm damage, and salt-air cleaning for coastal properties. We also take over orphaned systems left behind by installers who have since closed.
