What is Solar ATAP?
Solar ATAP stands for Aturan Tenaga Alternatif Persendirian (Self-Consumption Alternative Energy Arrangement). It replaced Malaysia's NEM 3.0 programme and is now the primary scheme for residential and commercial solar installations.
Under Solar ATAP, you install solar panels on your property, consume the energy you generate during the day, and export any excess to TNB (Tenaga Nasional Berhad) at a fixed rate.
How Do Credits Work?
The most important difference from NEM 3.0: credits reset monthly. Any excess energy you export to the grid earns credits at:
- RM 0.27/kWh — if your monthly usage is ≤1,500 kWh
- RM 0.37/kWh — if your monthly usage exceeds 1,500 kWh
Warning: Credits reset to zero at the end of each month. Unlike NEM 3.0 which had a 24-month rollover, you cannot accumulate credits. This makes right-sizing your system critical.
Right-Sizing Your System
Because credits reset monthly, an oversized system wastes money. The ideal system size generates enough energy to cover your daytime consumption with minimal excess. Factors to consider:
- • Your monthly TNB bill (higher bill = larger system makes sense)
- • Daytime consumption pattern (WFH = higher daytime usage)
- • Whether you'll add battery storage (increases self-consumption by ~30%)
- • Available roof space and orientation

How to Choose an Installer
Always choose a SEDA-registered installer. Key things to look for:
- • Valid SEDA registration number
- • At least 3 years of experience
- • Tier-1 panel brands (Jinko, LONGi, Canadian Solar, Trina)
- • Comprehensive warranty (25 years panels, 10+ years inverter)
- • Financing options including EPF withdrawal assistance
