Project Overview

All-black 6.6kW solar system with 13.3kWh of AlphaESS battery storage on a two-storey new build, designed around a narrow-lot roofline.

10200 kWh generated / year
$1850 Annual bill savings
7.4t CO2 offset / year
4.2 yrs Estimated payback

The Challenge

This two-storey home in a new Piara Waters estate had a narrow-lot roof broken up by hips, valleys and a neighbouring two-storey wall that shaded the lower west face in the afternoon. The owners also wanted the battery system out of sight from the street, with no clutter on the garage wall.

The Solution

We split the 15-panel array across the north and upper west faces to keep every panel out of the shade window, using all-black Trina Vertex S+ panels to sit cleanly against the dark roof. The AlphaESS hybrid inverter and two battery modules were installed along the side passage under a weatherproof awning, keeping the street frontage completely clear.

The Result

The system covers the family’s daytime usage and charges the battery by early afternoon, carrying them through the evening peak. Their first full power bill after installation came in at under a quarter of the previous one.

The whole process was effortless. The install crew were tidy, on time and talked us through the app before they left. Our last bill was $62.
