A busy family home on a tight urban plot, tired of fuel queues and a generator that woke the whole street. We built the array over the outbuilding roof and put the inverters and batteries in a dedicated plant room.

The case study
The problem
Fuel queues, a machine that ran most evenings, and no roof space where the obvious answer would fit. The plot made a straightforward rooftop install impossible.
What they had
Grid supply with a petrol generator run through the evening peak.
What it had to carry
- Lighting, fans and entertainment through the evening
- Refrigeration overnight
- Enough headroom to add cooling later
- An end to the generator noise in a dense residential street
What we installed
- Solar array laid across the outbuilding roof beside the main house
- Twin hybrid inverters with a lithium battery bank in a dedicated plant room
- New changeover panel wired into the existing house board
The installation
With no usable roof on the main house, the array went onto the outbuilding — panels hoisted up from the balcony by hand, one at a time, and set out across the flat roof. The plant room was built out with twin inverters and batteries, then tied into the house board through a new changeover panel.
After
The generator now sits idle for weeks at a time. The array is sized with headroom, so cooling can be added later without replacing the inverters or the battery bank.
