Body corporate rules made panels complicated. A backup-only system solved the actual problem, which was the outages, and the inverter is ready for panels if the rules change.

Durbanville. Household hybrid. July 2026.

projected payback

The household used 620 kW·h a month with a strong daytime load from a pool pump and home office. Twelve 550 W panels cover the day. The battery carries the evening and any outage.

Bellville. Commercial. May 2026.

Attorneys' office, 40 kW rooftop

Seventy-two panels across two roof planes, three-phase, no battery. Daytime grid draw cut to near zero.

4.2 yr
payback

Office loads are almost entirely daytime, so a battery would have added cost without saving much. The array offsets the tariff peak and exports a little at weekends.

Somerset West. Whole-home. March 2026.

Whole-home with EV charging

Twenty panels, 15 kW·h of storage, geyser on a timer and a 7 kW EV charger fed from the array during the day.

The client wanted the car charged from the roof. Smart load management holds the charger until the battery is above 80 per cent, then diverts surplus.
