Every plan priced for your house — year 1 and year 2, export credit included, ranked purely by cost. Never by commission.
Why solar, battery and EV homes especially
- Solar: your export earnings differ by thousands of kWh from the average — we price the export rate against what you actually send back.
- EV: cheap night windows (02:00–05:00 and the like) are worth wildly different amounts depending on when your charger actually runs. We know, because your data says.
- Battery: load-shifting changes which band your usage lands in — generic comparisons can't see that. Your meter data can.
No solar or EV? It still works — the maths is the same, and the answer is still yours rather than an average's.
