I used JE to compare NEM and a battery system for my parents’ single-storey home. The calculator showed NEM gave the fastest payback for their usage pattern — we installed it for them, and their monthly bills fell noticeably in three months. That outcome is what convinced me to plan our home’s system next year.

As a small studio, the upfront cost mattered. JE’s side-by-side comparison of NEM vs battery showed us the real numbers for our afternoon-heavy load. We installed panels on the office roof last quarter — electricity costs are down and staff love the sustainability story.

"I ran the numbers for my terrace house and JE showed a clear payback timeline. After installing a 5.5 kW system with a local installer in August, my monthly bill dropped by ~65%. Seeing those real numbers made the decision simple."
