What Is Malaysia’s Solar ATAP Programme?

Last updated: July 2026

The Solar Accelerated Transition Action Programme, commonly known as Solar ATAP, is Malaysia’s rooftop solar programme for eligible electricity consumers in Peninsular Malaysia. It allows consumers to install solar photovoltaic systems for their own electricity use and export eligible surplus generation to the grid for an energy offset under the programme’s rules.

Quick Answer Solar ATAP started on 1 January 2026 as a continuation of Malaysia’s Net Energy Metering programme. Eligible registered TNB consumers can install rooftop solar for self-consumption and export surplus solar electricity to the grid for an energy offset. Domestic capacity is generally limited to 5 kW for single-phase supply and 15 kW for three-phase supply. Non-domestic systems may be sized up to 100% of the consumer’s Maximum Demand, subject to technical assessment, with a maximum limit of 1,000 kW. The Solar ATAP contract period is ten years.

What Is the Solar Accelerated Transition Action Programme?

Solar ATAP is a consumer-based rooftop solar initiative introduced to increase the use of available rooftop space for renewable-energy generation. It continues the general self-consumption and surplus-export concept used under Malaysia’s earlier Net Energy Metering programme, with programme-specific eligibility, capacity, assessment and offset rules.

Self-Consumption First

Solar electricity generated at the premises is used to support the consumer’s own electricity demand.

Surplus Export

Eligible solar electricity that is not immediately consumed may be exported to the electricity grid.

Energy Offset

Eligible exported energy may create an electricity-bill offset based on the applicable Solar ATAP mechanism and rate.

Rooftop Renewable Energy

The programme is intended to support greater use of rooftop space for distributed solar generation.

Solar ATAP Is Not a Cash-Generation Scheme: Its main purpose is to support self-consumption and provide an energy offset for eligible surplus exports according to the programme and electricity-billing rules.

Who Administers and Regulates Solar ATAP?

PETRA The Ministry of Energy Transition and Water Transformation is responsible for the programme at government-policy level.

Energy Commission Suruhanjaya Tenaga regulates the programme and issues the applicable guidelines.

SEDA Malaysia The Sustainable Energy Development Authority acts as the programme’s implementing agency and operates the eATAP application system.

TNB Tenaga Nasional Berhad manages relevant electricity-supply, interconnection, technical-assessment, metering, contract and billing processes.

Different Parties Have Different Responsibilities: Programme approval, technical connection, meter work, installation and electricity billing may not all be handled by the same organisation.

How Does Solar ATAP Work?

Solar Generates Electricity

Rooftop solar panels convert sunlight into DC electricity during daylight hours.

The Inverter Converts Power

The inverter converts solar DC electricity into AC electricity that can be used by the premises.

The Premises Uses Solar First

Available solar generation helps supply the building’s active electrical loads.

Surplus May Be Exported

Solar energy exceeding the premises’ immediate demand may flow to the grid through the approved connection.

Eligible Exports Are Measured

The metering arrangement records eligible energy imported from and exported to the grid.

The Bill Applies the Offset

Eligible exported energy is treated according to the applicable Solar ATAP offset and billing mechanism.

Solar ATAP Does Not Make Electricity Bills Automatically Zero: The final bill depends on electricity consumption, solar generation, timing of consumption, eligible exports, applicable offset rules and other electricity-bill components.

Why Is Self-Consumption Important under Solar ATAP?

The direct use of solar electricity at the premises can be financially important because it reduces the amount of electricity that must be imported from the grid during solar-generating hours.

Daytime Loads

Air conditioning, machinery, refrigeration, pumps, office equipment and other daytime loads can use solar electricity directly.

Load Matching

A system designed around the premises’ daytime demand may achieve a higher self-consumption ratio.

Surplus Management

Oversized systems may export a larger share of generation rather than using it directly at the premises.

System Sizing

The most suitable size should consider consumption data, roof conditions, programme limits and expected export behaviour.

Maximum Permitted Capacity Is Not Always the Best Economic Size: Consumers should compare system cost, daytime usage, roof constraints, expected generation and the applicable export-offset mechanism.

Who Is Eligible to Apply for Solar ATAP?

Eligibility is subject to the official programme guidelines and the consumer’s electricity-account and installation status.

Registered TNB consumer
Premises located within the applicable TNB supply area
Eligible domestic or non-domestic electricity account
No conflicting registration under an existing NEM arrangement
No conflicting registration under the SelCo programme
No disqualifying existing solar PV arrangement
Complies with technical connection requirements
Complies with programme application requirements
Appoints a Registered PV Service Provider
Provides complete supporting documents
Completes required electrical installation work
Completes required testing and commissioning
Obtains technical assessment where applicable
Complies with licensing requirements where applicable
Uses an approved interconnection arrangement
Signs the required Solar ATAP contract

Some Electricity Arrangements Are Not Eligible: Consumers that are also generators under certain arrangements, and TNB accounts registered under tenant sub-meters in a multi-tenant scheme, may not qualify under the programme.

What Are the Solar ATAP Capacity Limits?

Consumer Category	General Capacity Limit	Main Condition
Domestic — Single Phase	Up to 5 kW	Subject to applicable connection and programme requirements
Domestic — Three Phase	Up to 15 kW	Subject to applicable connection and programme requirements
Non-Domestic	Up to 100% of Maximum Demand	Subject to technical assessment and system-design requirements
Maximum Non-Domestic Limit	1,000 kW	The project cannot exceed the programme’s overall maximum limit

Maximum Demand Matters for Non-Domestic Consumers: The allowable capacity is linked to the consumer’s Maximum Demand and may be reduced or conditioned by the technical assessment.

Which Solar ATAP Technical Assessments May Be Required?

The assessment requirement depends on consumer category, supply type, connection voltage and proposed solar capacity.

Category or Capacity	Possible Assessment	Published Study Fee
Domestic Single Phase above 5 kW	Connection Confirmation Check	RM1,000
Domestic Three Phase above 15 kW	Connection Confirmation Check	RM1,000
Non-Domestic from 1 kW to 72 kW	No listed CAS study under the published table	No study fee listed
Non-Domestic above 72 kW to 180 kW	Connection Assessment Study	RM1,000
Non-Domestic above 180 kW to 425 kW	Connection Assessment Study	RM5,000
Non-Domestic above 425 kW to 1 MW	Connection Assessment Study	RM8,000
High-Voltage Connection	Power System Study	RM15,000

The Assessment Can Affect the Final Approved Capacity: The electricity utility or appointed consultant may identify connection, protection, safety or capacity conditions that must be addressed before the project proceeds.

Fees and Assessment Requirements Can Be Updated: Applicants should confirm the latest official forms, thresholds and fees before making payment or finalising the proposed system capacity.

How Long Is the Solar ATAP Contract?

The Solar ATAP contract period is ten years from the contract’s commencement date.

During the Ten-Year Period Eligible surplus solar exports may receive the applicable energy offset under the Solar ATAP contract and billing rules.

After the Ten-Year Period The solar installation becomes strictly a self-consumption system at the premises.

No Continuing Export Offset After the contract period, excess exported energy does not receive the Solar ATAP offset under the expired arrangement.

No Continuing Roll-Over Any programme-specific roll-over treatment ends when the Solar ATAP contract period ends.

System Economics Should Extend beyond the Contract Period: The solar system may remain operational after ten years, but its financial value will depend more heavily on direct self-consumption once the Solar ATAP export-offset period ends.

How Do Consumers Apply for Solar ATAP?

Solar ATAP applications are submitted through SEDA Malaysia’s eATAP online system by an appointed Registered PV Service Provider.

How Can a Solar ATAP System Be Purchased?

Outright Cash Purchase

The site owner pays the system cost and normally becomes the owner of the installed solar equipment.

Loan or Credit Facility

The site owner finances the system through an approved lender, credit facility or payment arrangement.

Power Purchase Agreement

An investor owns the system and the consumer pays for the solar electricity generated according to the agreed energy rate.

Solar Leasing

The consumer pays an agreed rental amount for use of the system, with ownership treatment determined by the lease agreement.

Purchase Model	Typical System Owner	Main Payment Method
Cash Purchase	Site owner	One-time system payment
Loan or Credit Facility	Site owner, subject to financing terms	Scheduled financing repayment
Power Purchase Agreement	Registered solar investor	Payment based on solar electricity generated
Solar Lease	Depends on the lease period and agreement	Fixed or agreed rental payment

Solar ATAP Approval and Financing Are Separate Matters: Programme eligibility does not automatically mean that a loan, lease or power-purchase proposal is financially suitable.

How Does Solar ATAP Compare with NEM and SelCo?

Programme	Main Concept	Surplus Export Treatment
Solar ATAP	Self-consumption with eligible surplus export	Energy offset under the Solar ATAP rules and contract period
Earlier NEM Programme	Self-consumption with net-energy offset arrangements	Determined by the applicable NEM category and contract
SelCo	Solar generation for self-consumption at the premises	Generally structured around self-use rather than an ATAP export offset

Existing NEM Consumers Do Not Automatically Move to Solar ATAP: Existing programme rights and obligations remain subject to the consumer’s original approval, contract and applicable rules.

What Are the Potential Benefits of Solar ATAP?
