High-Performance Solar & Battery Solution for Inner-City Carlton Home
The Summary
Inner-city living in Melbourne comes with unique architectural and spatial considerations, but it also presents a prime opportunity to dramatically reduce household energy bills and carbon emissions. UNIfied Energy Services recently designed a comprehensive, high-efficiency residential solar and battery storage solution tailored for a property on Dorrit Street in Carlton for homeowner Peter Harcourt. The system features a 6.60 kW solar PV array paired with a Tesla Powerwall 2.0 battery and a Solis 5kW single-phase inverter.
The Solution
The custom-engineered system delivers exceptional performance figures, generating an estimated 4,884 kWh of clean energy annually. This robust output and enables the household to generate 151% of its annual energy needs from solar. With a 38% direct self-consumption rate further amplified by battery storage, the household achieves greater energy independence. Environmentally, the installation avoids approximately 5.2 tonnes of CO2 emissions each year, equating to planting over 1,000 trees or avoiding more than 156,000 km of car travel across the system’s lifetime.
Performance & Financial Impact
To address complex inner-city roofing profiles, urban shading, and multi-storey requirements, UNIfied’s installation incorporated 15 JA Solar 440W N-Type Bifacial Double Glass panels alongside a Tigo TS4 module-level optimiser to maximise efficiency across a split-array layout. The technical execution required specialised logistics, including an 8-meter scissor lift for double-storey access, mandatory edge protection, Klip-lok roofing mounts, and clean internal switchboard integration. To ensure long-term peace of mind, the project is fully backed by UNIfied’s industry-leading warranties, including a 25-year panel performance warranty, a 10-year extended inverter warranty, and a 5-year workmanship warranty.
