Solar ATAP Guidelines: Updated 2026 Guide for Malaysia

Solar ATAP has been discussed for much of 2025, but the official guidelines were only released at the end of December. Until then, many assumptions were based on partial announcements and early comparisons with NEM.

With the final rules now published, it is clear that Solar ATAP is not simply a renamed NEM programme. Several mechanics that previously supported aggressive system sizing and export-heavy designs have been tightened.

This article explains the updated Solar ATAP guidelines in practical terms, focusing on what has changed, why it changed, and how Malaysians should approach solar planning in 2026.

What Is Solar ATAP?

Solar ATAP stands for Solar Accelerated Transition Action Programme. It is Malaysia’s current framework for allowing rooftop solar systems in Peninsular Malaysia to export excess electricity to the grid under defined rules.

Key characteristics:

• Replaces Net Energy Metering (NEM) for new rooftop solar applications from 1 January 2026
• Applies to both residential (domestic) and non-domestic TNB customers
• Operates under a 10-year contract tenure
• Prioritises self-consumption, with surplus energy exported as bill credits

In short, Solar ATAP keeps the familiar idea of “use first, export the extra” but tightens how export credits are calculated, where they can be used, and what happens to unused credits.

Why the Updated Solar ATAP Guidelines Matter

The updated guidelines redefine how solar savings are generated.

Under earlier schemes like NEM 2.0 and NEM 3.0:

• Export credits could roll over (typically up to 12 months)
• Credits could offset multiple bill components, including network and, in some cases, capacity charges
• Oversizing was less risky because excess energy still had future value

Under Solar ATAP:

• Credits expire every billing cycle
• For domestic users, credits offset energy charges only
• Excess generation that cannot be used within the month can effectively have zero value

Why this matters:

• Poorly sized systems lose efficiency and financial value
• Savings vary more by user behaviour and time-of-use
• Daytime consumption becomes critical for payback

This makes solar planning less forgiving, but more predictable for grid operators and policymakers.

Key Aspects of the Updated Solar ATAP Guidelines

Export Credit Scope

For domestic users, export credits under Solar ATAP can only be used to offset the Energy Charge portion of the bill. Capacity, network, SST and other charges remain payable even if you produce more solar than you consume in a month, so bills will not reduce to zero through exports alone.

No Credit Rollover

Unused credits expire at the end of each billing cycle. There is no monthly or annual carry-forward, and excess exports during low-usage months are forfeited.

For households that travel often, or for seasonal businesses, this makes oversizing especially risky because “extra” generation in quiet months no longer subsidises future bills.

Capacity Limits and Eligibility

Residential (Domestic):

• Single-phase homes: up to 5 kW of solar PV under ATAP
• Three-phase homes: up to 15 kW

These are conservative caps compared to the roof size of many landed homes. They encourage designs based on realistic daytime usage rather than simply filling the roof and exporting as much as possible.

Non-domestic (Commercial, Industrial, Others):

• Solar capacity can be installed up to 100% of Maximum Demand (MD)
• Capped at 1,000 kW (1 MW) per account
• Larger systems may trigger detailed technical studies (e.g. CAS, PSS) before approval

Eligibility Basics:

• Must be a registered TNB customer in Peninsular Malaysia
• Must not be under an active NEM or SelCo contract (switching is possible but requires terminating the old contract and signing a new ATAP contract)
• Certain complex or multi-supply arrangements may be excluded

These limits sit within Malaysia’s broader renewable push. By late 2024, total installed solar capacity was around 2.3 GW, with rooftop systems estimated at about 1.75 GW, and NEM programmes contributing roughly 843 MW by August 2023.

Contract Duration and After 10 Years

Solar ATAP contracts run for a fixed 10-year period.

After the contract expires:

• The solar system can continue operating
• No export credits apply under ATAP
• All generation is considered self-consumption only

This is similar in spirit to the 10-year tenure for NEM schemes, but with stricter export rules during the contract itself.

No National Quota (But Capacity Is Still Managed)

There is no published national MW quota for Solar ATAP, unlike NEM 3.0 which had 700 MW for NEM Rakyat and 1,700 MW for NEM NOVA. ATAP applications are processed on a first-come-first-served basis, and total capacity remains subject to government decisions and local grid constraints.

In practice, this means there is no single “quota drop day” to panic over, but approvals can still be affected by future policy changes and grid headroom in your area.

How Solar ATAP Changes Real Outcomes for Consumers

This table focuses on outcomes, not programme mechanics. The main story is straightforward: alignment with daytime usage beats raw system size.

Who Solar ATAP Works Best For in 2026

Solar ATAP is best suited for:

• Homes occupied during daytime (WFH, retirees, home-based businesses)
• Work-from-home households with air-con and appliances running mid-day
• Offices, clinics, schools, and other 9am–5pm operations
• Factories and warehouses with steady daytime loads

It needs more caution when:

• Usage is mostly at night
• Premises are vacant during the day
• Systems are sized aggressively for export rather than self-consumption

Solar ATAP rewards alignment, not scale.

Malaysia’s Solar ATAP in Context: Why These Rules Look Stricter

Solar ATAP sits inside Malaysia’s broader energy transition. Under the National Energy Transition Roadmap (NETR), Malaysia is targeting a renewable energy share of 31% of installed capacity by 2025, 40% by 2035 and 70% by 2050, and solar is expected to play a major role.

Earlier NEM phases were launched when rooftop solar penetration was low. As total solar capacity has grown into the multi-GW range, generous 1:1 offsets with long credit rollover become harder to sustain without creating grid stability issues or shifting costs to non-solar consumers.

Solar ATAP keeps the basic export concept but tightens:

• What export credits can offset (energy charge only for homes)
• How non-domestic exports are valued (using Average System Marginal Price)
• What happens to unused credits (no rollover)

For consumers, the trade-off is clear: less “free riding” on exports, but still a strong incentive to use solar for self-consumption. For policymakers, ATAP is a way to scale rooftop solar toward NETR targets without overloading the grid or TNB’s balance sheet.

Realistic Sizing Examples for Malaysian Users

A recent study found that about 49% of Malaysian households consume 300–600 kWh per month, with an average bill around RM230 per month. Larger landed homes with multiple air-conditioners can easily reach 800–1,000 kWh per month or more.

Example 1: Double-storey terrace, 450 kWh/month

• Mostly empty at midday
• Here, nights and weekends dominate usage, and weekdays from 10am–4pm are light.
• Under NEM, a 6 kW system could still work because rolled-over credits helped cover future bills
• Under ATAP, many of those weekday exports will become unused credits and expire. 
• A 3–4 kW system tuned to daytime base loads (fridge, networking, fans, maybe a bit of air-con) is likely more efficient.

Example 2: WFH household, 700 kWh/month

• Strong daytime air-con
• A work-from-home couple running air-con and appliances during the day has a load curve that matches solar much more closely.
• A 5 kW single-phase or 7–8 kW three-phase system may track daytime usage well, with most generation self-consumed and only a modest share exported
• ATAP’s monthly expiry is far less painful.

Example 3: Office-based SME, 2,000–3,000 kWh/month

• 9am–6pm
• This kind of business benefits from high daytime load and can consider installing close to 100% of Maximum Demand (up to 1 MW) under ATAP. 
• The key risk is volatility in SMP (which determines export credit value)
• Many SMEs will favour designs that focus on matching typical weekday load rather than fully maxing out the 100% MD allowance.

Across all three examples, the rule of thumb is the same: design for self-consumption first, export second.

Already on NEM? What Solar ATAP Means for You

If you already have a NEM 2.0 or 3.0 system, Solar ATAP does not automatically change your existing agreement. 

The government has confirmed that NEM users continue under their original terms, including how offsets and rollover work, until their contract or offset period ends.

The ATAP guidelines and SEDA FAQ do allow for certain NEM customers to terminate their existing contract and re-contract under ATAP if they choose. However, once you move to ATAP, you accept ATAP’s rules for the next 10 years, including monthly credit expiry, and you cannot revert to NEM terms.

How Solar ATAP Fits Malaysia’s Energy Policy Direction

Policy priorities behind the changes include:

• Reducing grid strain from excess midday exports
• Preventing widespread oversizing that pushes costs onto non-solar users
• Improving the predictability of grid operations as renewables scale

Solar ATAP signals a more mature phase of rooftop solar adoption, not a retreat from renewables. It fits into the NETR and MyRER roadmaps, which rely on solar to meet ambitious long-term renewable energy targets while keeping the system stable and tariffs manageable.

How Malaysians Should Approach Solar ATAP in 2026

Solar ATAP does not remove the value of rooftop solar, but it raises the standard for planning and expectation management. The most successful systems will be those designed around real consumption rather than export potential, with careful attention to daytime usage and realistic system sizing.
