Solar ATAP or SELCO? Choosing the right scheme for your business
Both let a business use its own rooftop solar. The difference is what happens to the power you do not use.
A business installing rooftop solar in Peninsular Malaysia will normally do so under one of two frameworks: Solar ATAP or SELCO (self-consumption). Both are legitimate routes. The right one depends on your size and on how closely your solar output matches your daytime load.
The short version
| Solar ATAP | SELCO | |
|---|---|---|
| Main idea | Use your own solar first, export the surplus for bill credits | Use all your solar on site, no export credit |
| System size | Up to 100% of your maximum demand, capped at 1 MWac | Can exceed 1 MWac, subject to technical assessment |
| Surplus energy | Credited at the average System Marginal Price, within the same month | Not credited |
| Contract | 10 years | No export contract |
| Above 1 MWac | Not available | Standby charge of RM12 per kWp and a battery storage requirement apply |
What changed for SELCO
The Energy Commission revised the SELCO guidelines on 31 December 2025. The standby charge now applies only to systems above 1 MWac, and so does the requirement to install battery storage. Previously the battery requirement started at 72 kWp, which caught many mid-sized factories.
How to choose
- Your daytime load is steady and higher than your solar output: you will use nearly everything you generate. Either scheme works, and the decision comes down to paperwork and future flexibility.
- You have quiet days, such as weekends or shutdowns: Solar ATAP gives some value for the surplus, although business export credits are lower than home credits and expire monthly.
- You need more than 1 MWac: SELCO is the route, with storage and the standby charge built into the business case.
Whichever you choose, size the system for self-consumption. Under both schemes, the power you use directly is worth the most.
Scheme rules are set by the Energy Commission and SEDA Malaysia and can change. We confirm the current requirements for your site before any application is submitted.
