East Coast Neighbours, Part 3: The Fourth Home Completes the Street

The fourth and final home on this same East Coast street went solar, completing a sequence of four neighbouring households that each made the same decision one after another. Here's what this last installation involved, and what the full pattern actually suggests.

What was actually installed at this fourth home?

AIKO NEOSTAR 540W bifacial panels totalling 12 kWp, fully commissioned and connected to the grid, matching the panel technology and scale of the third home on this same street and the first two homes before that.

What does "four homes, one street" actually mean in practice?

Four separate households on the same stretch of road, each with its own independent system, account, and EMA and SP Group registration, arrived at the same decision in sequence rather than through a single coordinated project. Each new installation followed direct observation of a neighbour's real, operating system, not a group purchase or a shared plan agreed upfront.

Does a fully solar street actually look any different?

Four homes with visually similar dark panel arrays on neighbouring roofs create a level of visible, everyday normalcy that a single isolated installation doesn't. For anyone else on this street who hasn't gone solar yet, four real, working examples are now directly visible rather than something to look up online.

Whether this changes how any remaining households on the street eventually decide isn't something Sunnify can state as fact, but the pattern across these four homes suggests visibility itself is doing real work.

What does Sunnify actually track across a sequence like this?

The real system specifications, savings projections, and general story each household agreed to share, in the order the installations happened. This isn't a formally studied research project, just an honestly documented pattern across four real, verifiable installations on one Singapore street, shared because the pattern itself is genuinely useful for anyone weighing the same 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, consistent with the other ~12 kWp systems installed earlier on this same East Coast street.

What does this sequence actually suggest about neighbour influence on solar adoption?

A real, visible installation nearby appears to function as concrete proof in a way that marketing material or a stranger's review can't replicate. Each household in this sequence had the same access to information about solar generally, articles, calculators, sales conversations, but it was specifically watching a neighbour's system operate day to day that moved the decision from consideration to an actual quote request.

What would this pattern look like on your own street?

If a neighbour has already installed solar, asking to see their system and hear about their actual experience, install timeline, and real savings is a genuinely useful, low-cost step before requesting your own quotes. It's the same kind of direct, local evidence that moved each of these four households along this particular East Coast street, one after another, over what these installations suggest was a genuinely organic, unplanned sequence.
