SoyaCincau reported in early December 2025 that Solar ATAP registration wouldn't open in December as previously signalled — instead launching with the programme on 1 January 2026. For installers and customers in the middle of staging applications, the one-month shift mattered less than it sounded. Most customers were on a 4-8 week design-to-commissioning cycle anyway, so the timing slipped without much disruption.
- Original signal: December 2025 registration opening
- Actual opening: 1 January 2026 (programme launch day)
- Reason: portal and workflow finalisation
- No applications were lost — pre-launch enquiries were retained for processing post-launch
- Installers continued accepting customer designs throughout December
Why the delay was minor in practice
From our end: we kept taking customer enquiries through December, completing site assessments, preparing system designs and quotes. The only thing that paused was the actual SEDA portal submission, which moved from "any day now" to "1 January for sure". By the time the portal opened, we had a staged queue of customers whose designs were already done, ready to file on day one.
What changed during the delay window
The extra month let SEDA finalise the application portal UX, align Single Buyer / TNB credit-accounting interfaces, and publish the technical guidelines installers needed. The 19 December PETRA media statement confirmed the launch, and the operational rollout ran on schedule from 1 January onwards.
What this means for you now
If you're applying in 2026, the December 2025 delay is old news. The actionable advice today: gather your documents (TNB bills, IC, property title), start a conversation with a SEDA-registered installer, and let us walk you through the design. See our documents checklist for the residential and commercial paperwork lists, and the step-by-step application guide for the full process.
