Malaysia Solar Regulations 2026

Malaysia’s solar market runs on NEM 3.0 — a quota-based net metering scheme managed by SEDA that determines whether a commercial or residential solar system can legally export to the TNB grid. The scheme has capacity rounds; systems installed without SEDA approval cannot legally net meter, and TNB will not install the bi-directional meter. This guide covers the complete compliance stack: NEM 3.0 quotas, TNB grid connection, tax incentives, Sarawak’s separate scheme under SEB, and how C&I buyers choose between NEM, SELCO, and LSS.

Malaysia Solar Market Overview

Malaysia’s near-equatorial location gives it irradiance of 4.5–5.5 peak sun hours (PSH) per day across most of the peninsula and Borneo, with relatively low seasonal variation compared to higher-latitude markets. This consistent irradiance profile produces high solar yield — typically 1,400–1,600 kWh/kWp/year — which underpins strong financial returns for commercial NEM systems.

The market has three distinct grid-connected solar pathways:

For off-grid systems (not grid-connected), neither SEDA nor TNB approval is required, but equipment must meet Malaysian standards (MS IEC 62109, MS IEC 61215).

NEM 3.0: Malaysia’s Core Solar Export Scheme

How NEM 3.0 Works

NEM 3.0 is a net billing scheme — not gross metering. The bi-directional TNB meter records:

• Import: kWh drawn from the TNB grid (billed at the customer’s standard tariff)
• Export: kWh pushed to the TNB grid from the solar system (credited at 1:1 offset rate)

At billing time, exported kWh are offset against imported kWh at a 1:1 ratio:

Net Bill = (kWh imported × tariff rate) − (kWh exported × tariff rate)

If exports exceed imports in a billing month, the net credit carries forward to the following month. Credits do not carry forward indefinitely — confirm the current credit rollover rules with SEDA at the time of application.

NEM 3.0 Size Limits

For non-domestic customers, the Maximum Demand figure is taken from the TNB billing statement. A customer whose bill shows 100 kW MD can install up to 75 kWp under NEM 3.0.

SEDA NEM Application Portal

Applications are submitted via nem.seda.gov.my. The portal requires:

• Customer TNB account number
• Proposed system capacity (kWp)
• Installation address
• Applicant NRIC (individual) or company registration number
• SEDA-registered solar contractor ID

SEDA publishes quota rounds with total capacity allocation per round. Applicants who apply within a quota round receive approval from the available quota pool. Monitor seda.gov.my for quota round announcements — quota is finite and rounds fill up.

TNB Grid Connection Requirements (Peninsular Malaysia)

For NEM 3.0 systems connected to TNB’s Peninsular network, the technical connection requirements are set by TNB’s Distribution Code and the Energy Commission’s Grid Code.

Inverter Requirements

All grid-connected inverters must meet:

• Anti-islanding protection: automatic disconnection within 2 seconds of loss of TNB supply
• Voltage protection: disconnect if voltage exceeds 110% or falls below 85% of nominal
• Frequency protection: disconnect if frequency falls outside 47.5–52.0 Hz
• Standards: MS IEC 62109 (safety) or IEC 62109 equivalent recognised by the Energy Commission

Protection Relay (Systems Above 75 kWp)

Commercial NEM systems above 75 kWp typically require a dedicated protection relay installed at the point of connection with TNB’s network. TNB specifies the relay settings during the technical assessment. The relay must be type-approved and settings verified during the TNB inspection.

PE-Stamped Single-Line Diagram

All grid-connected solar applications in Malaysia require a Single-Line Diagram (SLD) stamped by a Professional Engineer (PE) registered with the Board of Engineers Malaysia (BEM). The SLD must show the solar array configuration, inverter, protection devices, metering arrangement, and connection to the TNB distribution network.

Sarawak: SEB’s Separate Solar Scheme

Sarawak operates its own electricity grid under Sarawak Energy Berhad (SEB), separate from TNB’s Peninsular network. Solar installations in Sarawak follow SEB’s own NEM rules and application process:

• Applications submitted via SEB’s portal (not SEDA’s nem.seda.gov.my)
• System size caps and export credit rates are set by SEB and may differ from NEM 3.0
• The Sarawak Electricity Ordinance governs electrical connections — different from Peninsular law
• PE stamp requirements and contractor licensing are governed by Sarawak’s separate engineering registration rules

For detailed Sarawak requirements, see the SEB Sarawak Solar Guide.

Malaysia Solar Tax Incentives

GITA — Green Investment Tax Allowance

GITA provides qualifying solar investors with a 100% Investment Tax Allowance (ITA) on capital expenditure for green technology assets (including solar PV systems) for 3 years from the date of first qualifying expenditure. The ITA can be offset against 70% of statutory income per year, with unutilised allowance carried forward until fully absorbed.

Eligibility:

• Company must be a Malaysian tax resident
• Solar system must be for own use (not generation for third-party sale)
• MIDA approval required before claiming

GITE — Green Income Tax Exemption

GITE provides qualifying solar energy service companies with a 70% income tax exemption on statutory income derived from solar energy services for 10 years. This incentive targets companies that generate, distribute, or supply solar energy services — including businesses selling solar energy from rooftop systems under a third-party PPA model.

Eligibility:

• Company must be a qualifying green technology service provider
• MIDA approval required
• Income must be derived from qualifying solar energy activities

Import Duty and Sales Tax

Solar PV modules, inverters, mounting systems, and associated electrical components imported for solar projects may qualify for import duty and sales tax exemption under the customs duty exemption schedule. Confirm current HS codes and exemption status with the Royal Malaysian Customs Department (RMCD) — exemptions are reviewed periodically.

C&I Solar Pathways: NEM vs SELCO vs LSS

Commercial and industrial buyers in Malaysia choose between three pathways based on system size, export strategy, and regulatory risk appetite:

For most C&I buyers below 1 MW, NEM 3.0 is the preferred route because the 1:1 export credit preserves full financial value for surplus generation. SELCO suits operations with high base load that can consume all solar generation on-site — avoiding the SEDA quota process at the cost of losing export credit. For a full analysis, see the C&I Solar Malaysia guide.

Compliance Timeline: NEM 3.0 Installation

Total timeline: 4–6 months from SEDA application to first NEM bill for commercial systems. Domestic systems (12 kWp or less) are typically faster: 2–4 months.

Malaysian Electrical Licensing for Solar Installers

All electrical work on the consumer side of the TNB supply point in Peninsular Malaysia must be performed by a licensed electrical contractor registered with the Energy Commission under the Electricity Supply Act 1990.

Contractor and Electrician Licensing

SEDA maintains a register of solar PV contractors and installers who are eligible to submit NEM applications on behalf of customers. A contractor must be on SEDA’s register before an NEM application listing their firm will be accepted.

Professional Engineer (PE) Requirement

All grid-connected solar installations in Malaysia require engineering drawings stamped by a PE registered with the Board of Engineers Malaysia (BEM). The PE takes professional responsibility for the Single-Line Diagram and the system’s compliance with Malaysian standards.

Equipment Standards

Solar Panels

Solar panels installed on grid-connected systems should meet IEC 61215 (crystalline silicon) or IEC 61646 (thin film) for performance, and IEC 61730 for safety. Imported panels are subject to SIRIM certification — the Sales Tax (Goods Exempted From Sales Tax) Order should be confirmed for current exemptions.

Inverters

Grid-connected inverters must comply with MS IEC 62109-1 (safety) and MS IEC 62109-2 (grid requirements). The inverter must include anti-islanding function compliant with IEEE 929 or IEC 62116. Inverters must be approved by the Energy Commission — check ST’s approved equipment list before specifying.

Wiring and Protection

All wiring must comply with the Electricity Regulations 1994 and MS IEC 60364 series. DC wiring must use UV-rated solar cable (TÜV 2 PfG 1169 or equivalent). DC isolators, AC isolators, surge protection devices (SPD), and residual current devices (RCD) must meet relevant IEC standards.

Frequently Asked Questions

Can I install solar in Malaysia without SEDA approval? Yes — off-grid systems require no SEDA approval. For grid-connected self-consumption systems (SELCO), no SEDA approval is needed, but TNB grid connection approval is still required. NEM systems (where you want to export surplus to the grid and receive bill credits) require SEDA approval before installation. Energising a NEM system without SEDA approval means TNB will not install the bi-directional meter.

Does Malaysia’s NEM 3.0 apply in Sabah and Labuan? NEM is available in Sabah and Labuan, but managed by SESB (Sabah Electricity Sdn Bhd) under a separate scheme. The application process, system size caps, and export credit terms are set by SESB — not SEDA’s nem.seda.gov.my portal. Contact SESB directly for current Sabah NEM terms.

What happens to NEM export credits if I close my TNB account? NEM credits accumulated on your TNB account are linked to that account. If you close the account, transfer ownership, or move premises, unrecovered credits may be forfeited. Confirm the credit treatment policy with TNB before any account transition, particularly for commercial tenants who have invested in solar systems under lease agreements.

Is battery storage allowed under Malaysia’s NEM 3.0? Battery storage can be added to an NEM-approved system but requires TNB’s approval for the modified system configuration. A system with battery storage that is capable of both storing and exporting energy creates additional metering complexity — TNB will assess whether the existing bi-directional NEM meter is sufficient or whether additional metering or protection is needed. Notify TNB before installing storage on an existing NEM system.
