SELCO vs ATAP: Understanding the Key Differences in Malaysia’s Solar Future

As Malaysia accelerates its transition toward renewable energy, businesses and homeowners are faced with multiple options to maximize savings and sustainability through solar adoption. Two of the most talked-about frameworks today are SELCO (Self-Consumption Solar with Battery Storage) and the Solar Accelerated Transition Action Programme (Solar ATAP).

While both aim to reduce reliance on the national grid and lower electricity costs, the differences between them are significant. Choosing the right program depends on your energy profile, consumption habits, and long-term financial goals.
 

What is SELCO?

SELCO (with battery storage) is a scheme focused on maximizing self-consumption. This means that the electricity generated by solar panels is primarily used to power your own home or business, with excess energy stored in batteries for later use, particularly useful at night.

• Aim: Maximize on-site consumption and reduce reliance on grid power.

• Grid Export: No export credit is given, your system is designed to store rather than sell excess electricity.

• Capacity Limit:

  • 5kWac for single-phase connections.

  • 12.5kWac for three-phase connections.

• Payback Period: Generally shorter due to savings achieved by maximizing self-use.

• Contract Period: Lifetime (system continues as long as the equipment lasts).

• Ideal Users: Homes or facilities with higher nighttime usage (where batteries can discharge during peak evening hours).

• Policy Timeline: Already existing and in place.

In short, SELCO is the right choice for homeowners or small businesses that want energy independence and stability, especially when nighttime usage is significant.
 

What is ATAP?

The Accelerated Transition Action Programme (ATAP) is Malaysia’s upcoming solar framework designed to boost adoption at a national scale. Unlike SELCO, ATAP focuses on exporting excess electricity back to the grid, where it is offset against your consumption at the System Marginal Price (SMP) rate.

• Aim: Offset electricity bills based on the SMP.

• Grid Export: Excess energy is exported to the grid at SMP rates.

• Capacity Limit: 100% of your maximum demand, making it scalable for larger energy users.

• Payback Period: Typically longer than SELCO due to dependence on export rates.

• Contract Period: Lifetime, subject to regulatory approval.

• Ideal Users: Homes or businesses with high daytime usage (where solar production aligns with demand).

• Policy Timeline: Scheduled to begin from 1st December 2025 onwards.

ATAP offers an attractive opportunity for those who want to take advantage of daytime solar production and leverage grid offsetting for cost savings.
 

SELCO vs ATAP: Which One is Right for You?

The Bigger Picture: Malaysia’s Solar Transition

Both SELCO and ATAP are integral to Malaysia’s renewable energy roadmap.

• SELCO strengthens energy independence by promoting storage and resilience.

• ATAP enables mass adoption and aligns solar users with national grid decarbonization strategies.

The choice ultimately depends on your energy consumption patterns:

• If you use more power at night → SELCO is better.

• If your usage peaks during the day → ATAP is the smarter option.
