In Malaysia, there are two main ways to connect your solar system to the grid. Choosing the wrong one can cost you money.
Solar ATAP
The Gist: Excess power you export earns a credit on your TNB bill (it is a bill credit, not cash).
Best For: Residential homes and SMEs.
Key Benefit: Export credit at the Energy Charge (homes) or the Average SMP (businesses); unused credit is forfeited at the end of each billing period.
Constraint: Capacity is set by the Government and allocated first come, first served.
SELCO (Self-Consumption)
The Gist: You use everything you generate. Zero export.
Best For: Large factories with 24/7 operations that consume 100% of solar yield instantly.
Key Benefit: No export, so no dependence on export credit rates; system size follows your own load.
Constraint: You must install a "Zero Export Device" to prevent backflow to the grid.
Which One Should You Choose?
The choice depends on your load profile and premises. Solar ATAP suits homes and businesses that export some daytime output; for a heavy industrial user, SELCO provides more flexibility in system sizing.
