East Coast Neighbours, Part 2: The Third Home Joins, $3,720 a Year

A third home on this same East Coast street went solar, fitted with a 12 kWp system of AIKO NEOSTAR 540W bifacial panels, after watching two neighbours' systems run first. Here's what actually changed for this household's decision, and what happened next on the street.

What was actually installed at this third home?

AIKO NEOSTAR 540W bifacial panels totalling 12 kWp, rail-mounted flush to the roof profile, matching the panel technology the first two homes on this same East Coast street had already installed months earlier.

Why did this homeowner wait to see two neighbours go first?

Watching a real, operating system on a nearby roof answers questions a sales conversation alone often leaves open: whether the panels actually look the way they were described, whether the installation process matched what was promised, and whether the projected savings held up once the system was actually running. That direct evidence, from someone on the same street rather than a stranger's online review, carries real weight.

See how AIKO's bifacial panel technology actually works for the technical detail behind the panel choice all three homes made.

What specifically can a neighbour's real system actually confirm?

A full billing cycle's actual savings, not a projection; how the monitoring app looks in daily use; and how the system performs through Singapore's rainier stretches, not just on a clear day. These are exactly the details a sales conversation can describe but can't prove the way a working neighbour's system can.

For this third household, that kind of direct, first-hand confirmation appears to have mattered more than any additional marketing material or independent research could have.

Does watching two systems, rather than one, change anything?

Two independent examples on the same street, rather than one, offer a slightly stronger form of the same evidence: it's harder to dismiss two separate households' real results as an isolated case. By the time this third home moved forward, there was more direct local proof available than the first two households had when they made their own decision.

How much does this system actually save?

Around $310 a month, roughly $3,720 a year, based on Sunnify's projection for this 12 kWp system at the Q3 2026 EMA regulated tariff of S$0.3478/kWh, 25% self-consumption, and an SCT export credit of S$0.2581/kWh, closely matching what each of the earlier two homes on this same East Coast street individually project for their own separate systems.

Does watching a neighbour's real system actually change how someone evaluates solar?

In practice, yes, and this sequence is a direct illustration of it. A visible, working installation nearby removes a category of uncertainty a brochure or online research can't fully resolve, since it's proof the system works on a comparable roof in the same neighbourhood, not just in a manufacturer's marketing material or a generic online review from a stranger.

What happened next on this street?

A fourth home followed, this third installation apparently offering the same kind of direct, local proof to yet another neighbour that the first two had offered this household. See the fourth and final home to complete this street's group for how the sequence concluded.
