Panels generate DC
Your rooftop array converts daylight into DC electricity.
On-Grid · Lowest cost, biggest saving
An on-grid system has the fewest components, the lowest cost per kW and the fastest payback. With net metering your surplus daytime generation offsets what you draw at night. The trade-off is simple and worth understanding: when the grid goes down, so does your system.
How it works
Your rooftop array converts daylight into DC electricity.
A grid-tied inverter turns it into the 220V AC your building runs on, synchronised to the grid.
Everything running during daylight uses sunlight instead of paid grid units.
Anything left over flows out through your bidirectional meter and is credited against your bill.
Who it suits
Key benefits
No battery cost means the lowest price per kW and the shortest time to break even.
No batteries means no replacement cost in year eight or ten.
Export credits can take a bill close to zero across the year.
Fewer components, less to service, less to go wrong.
