In mid-November 2025, SolarQuarter reported the Solar ATAP scheme's anticipated launch on 1 December 2025. The date subsequently moved — first to a December delay, then to the eventual 1 January 2026 launch confirmed by PETRA on 19 December. Through Q4 2025, installers like us watched the dates drift and adjusted customer queues without breaking stride.
- Initial signal: 1 December 2025 launch target
- Revised: pushed back, then formally announced for 1 January 2026
- Original framing emphasised continued enhancement of rooftop solar adoption
- Programme operator: SEDA + ST + TNB
- Replaces NEM 3.0
Reading the rolling launch dates
Through Q4 2025, Solar ATAP's launch date moved a few times as the Ministry and SEDA finalised technical guidelines, portal UX, and TNB grid-connection workflow updates. The November SolarQuarter framing pointed to early December; the early-December SoyaCincau update flagged the delay; PETRA's 19 December statement confirmed 1 January 2026. For installers, the date instability was background noise — the customer pipeline kept moving.
What was consistent across the date shifts
Despite the moving target dates, the programme's design held steady from November onwards: continuous enrolment with no fixed quota, 100% Maximum Demand sizing for commercial, and a clean replacement for NEM 3.0 routed through SEDA-registered installers. The delays were administrative rather than substantive, which is why installers and customers absorbed them without disruption.
What this means today
The December 2025 / January 2026 timing history is settled background now. If you're applying in 2026, the operative date is 1 January onwards — and the programme has been processing applications continuously since.
