For most Diamond Bay homes, solar pays back faster than battery on its own — but installing both together saves on truck rolls, electrician callouts and DNSP applications. NGS sizes solar and battery installation together based on your actual bill, then tells you the brand-neutral right answer: do both now, stage them, or solar first and battery later when prices drop further.
