East Coast Neighbours, Part 1: Two Homes, One Street, 24 kWp Combined

The first two homes on one East Coast street to go solar, each fitted with a 12 kWp system of AIKO NEOSTAR 540W bifacial panels. Here's what these two installations actually involved, and what happened on their own street afterward.

What was actually installed across these two homes?

Two separate systems, each roughly 12 kWp, using AIKO NEOSTAR 540W bifacial panels rail-mounted flush to each property's own roof. Combined, the two installations total 24 kWp, fully commissioned and exporting side by side on neighbouring rooftops along the same East Coast street.

Why do neighbours going solar together actually matter?

A neighbour's real, actually-installed system, sitting visibly on a roof down the road, answers questions a sales conversation alone often can't: what the panels actually look like on a similar roof, whether the installation process matched what was promised, and whether the savings materialise as projected once the system is running day to day. That direct, local evidence carries weight a brochure or a stranger's online review simply doesn't.

See AIKO's ABC and N-type panel technology for how the bifacial panels both homes chose actually work.

How much does this combined system actually save?

Around $620 a month combined, roughly $7,450 a year, based on Sunnify's projection for these two ~12 kWp systems (24 kWp combined) 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, real figures shared publicly with both homeowners' explicit permission.

What happened after these two homes went solar?

Two more homes on the same street followed, each apparently influenced by watching these first two systems operate. See the third home to join this street and the fourth home that completed the group for how the sequence continued.

Does a shared decision like this actually change the installation process itself?

Not technically. Each home still goes through its own independent site assessment, its own LEW commissioning, and its own EMA and SP Group registration, exactly as any standalone landed home would, run by whichever installer each household separately chose. What changes is the homeowner's confidence going in, not the regulatory or technical process itself.

Why does Sunnify withhold the specific addresses here?

Both homeowners agreed to share their real system size, savings, and story, but not their specific street address, a reasonable and common boundary for a case study involving identifiable private homes. Documenting real projects transparently doesn't require publishing exactly where they are, only that the figures and outcomes described are genuine.

This is consistent with how every Sunnify case study handles homeowner privacy: real data and a real, verifiable outcome, without compromising a specific family's privacy just to publish an exact street address.

What would encourage a similar sequence on your own street?

A visible, real installation nearby is the single most concrete thing that tends to move a hesitant neighbour from considering solar to actually requesting a quote, more persuasive in practice than another article, calculator, or sales conversation. If a neighbour has already gone solar, asking to see their system and hear about their actual experience, install timeline, and real monthly savings is a genuinely useful step before requesting your own quotes.
