Designed for homes that want to start with solar now and keep the option open for battery storage later. A clean, simple solar package using quality panels, a battery-ready inverter, and proven Clenergy roof mounting.
Small homes, daytime usage, future upgrade path
Our balanced home solar and battery package. Suits many four-bedroom homes and gives the household meaningful evening energy storage without jumping straight to a full off-grid-style system.
3–4 bedroom homes, families
Designed for larger island homes that want serious solar production, high battery capacity, and stronger backup capability. Well suited to homes with larger evening loads, pumps, air-conditioning, EV charging, or generator backup requirements.
Large homes, high energy users
For properties where the power system needs to be designed around the site, not pulled from a shelf. Includes off-grid homes, larger architectural builds, generator-backed systems, EV charging, pump systems, spas, workshops, and properties with high or unusual loads. Final design is completed after load assessment, roof review, switchboard inspection, and energy modelling.
Architectural builds, off-grid, heavy loads
PV (Photovoltaic) panels are the foundation of any solar solution, determining electricity generation.
Quality panels and a well-designed plan ensure optimal performance. We supply premium panels from Tier 1 manufacturers, global leaders in Solar PV.
