Malaysia’s shift toward cleaner energy has accelerated the development of solar farms and large-scale solar systems. Under the National Renewable Energy Policy, renewables are targeted to contribute 31% of national energy capacity by 2025, excluding large-scale hydro.
This makes it essential to understand how solar farms work in Malaysia, their cost structures, regulatory requirements, and investment considerations before engaging a supplier or development partner.
Regulatory Framework and National Schemes
Solar farm development in Malaysia is governed by national regulators and structured renewable energy programmes designed to support utility-scale deployment including:
- Regulatory authorities: Solar farms are regulated by Suruhanjaya Tenaga (Energy Commission) and the Sustainable Energy Development Authority (SEDA), which oversee licensing, compliance, and renewable energy policy implementation.
- Large Scale Solar (LSS) programme: The LSS programme is the primary mechanism for utility-scale solar farms, using competitive bidding to reduce the Levelized Cost of Energy (LCOE) for projects typically ranging from 1MW to 50MW, with LSS5 launched in April 2024 offering a 2GW quota.
- Net Energy Metering (NEM): The NEM scheme allows solar system owners to export excess electricity to the national grid and receive bill credits, supporting grid-connected self-generation.
- Self-Consumption (SELCO): SELCO enables commercial and industrial users to generate solar energy for on-site use without exporting power to the grid.
- Feed-in Tariff (FiT): The FiT programme played a key role in Malaysia’s early solar market but is no longer the main driver for new large-scale solar farm development.
Investment and Economic Feasibility
Solar farm investments in Malaysia generally offer attractive, long-term returns, influenced by factors such as project scale, financing structure, and proximity to grid infrastructure. Development costs average RM3 to RM4 million per megawatt, with construction timelines ranging from six to twelve months.
To reduce upfront capital requirements, many developers offer Solar Power Purchase Agreements (PPAs), where systems are installed and maintained at no initial cost, and electricity is sold to offtakers at rates lower than utility tariffs.
For landowners, solar land leasing provides an opportunity to earn stable, long-term income for up to 25 years without investing in infrastructure, particularly for sites that meet technical and regulatory criteria.
Land Requirements and Site Suitability
The success of a solar farm in Malaysia depends on land size, site conditions, grid access, and compliance with local land regulations. Key factors to evaluate include:
- Minimum land size: A 5MW utility-scale solar farm typically requires around 15 hectares, with most developers preferring at least 40 acres to ensure economic viability.
- Physical site characteristics: Land should be flat, open, and unshaded, with minimal tree cover or terrain variation to avoid energy losses caused by shading.
- Grid proximity: Sites located within 1km of a TNB Transmission Main Intake (PMU) substation are strongly preferred, as closer proximity reduces grid connection and power transfer costs.
- Land classification: Under the National Land Code 1965, land is categorised as agricultural, building, or industrial. Solar farms are generally treated as industrial developments, even when built on agricultural land.
- State-level permits: Some states, such as Johor, issue Special Permits that allow agricultural land to be used for solar development for up to 25 years without requiring full land-use conversion.
Technical Infrastructure and Types of Installations
Solar farms in Malaysia are built using installation and infrastructure models designed to maximise land efficiency and support long-term operational reliability.
1. Ground-Mounted Solar Farms
Ground-mounted systems are the most common installation type and are often paired with agro-photovoltaic models, allowing crops or livestock to coexist beneath solar arrays.
2. Floating Solar Farms
Floating solar farms are increasingly deployed on lakes and former mining pools, helping conserve land and reduce water evaporation. This installation type is particularly suitable for Malaysia, where unused water bodies are widely available and land conversion can be restrictive.
3. Core Solar Farm Infrastructure
All utility-scale solar farms rely on photovoltaic panels to generate electricity, supported by inverters that convert DC to AC power. Transformers and substations regulate voltage levels to ensure safe and stable grid integration.
4. Monitoring and Performance Optimisation Systems
Modern solar farms commonly integrate AIOT-based monitoring systems for real-time performance tracking, predictive maintenance, and operational optimisation.
Operation, Maintenance, and Decommissioning
Solar farm operation in Malaysia is relatively low-maintenance due to the tropical climate, with natural rainfall assisting panel cleaning. Professional cleaning is typically required every two to three years, alongside regular inspections to ensure safety and system performance.
Most solar farms operate for 21 to 25 years. At the end of their lifecycle, decommissioning involves disconnecting from the grid, removing all infrastructure, and restoring the land. If a project is abandoned for more than one year without notification, local authorities may intervene to carry out decommissioning works.

FAQ
1. What is a solar farm in Malaysia?
A solar farm in Malaysia is a large-scale solar power facility that generates electricity using photovoltaic panels and supplies power to the national grid or private offtakers, typically developed under the LSS programme.
2. How does the Large Scale Solar (LSS) programme work?
The LSS programme is a competitive bidding scheme administered by SEDA that enables developers to build utility-scale solar farms and sell electricity through long-term agreements.
3. Is investing in a solar farm in Malaysia viable?
Solar farm projects are considered viable due to supportive government policies, predictable solar resources, and long-term power purchase structures, subject to land suitability and grid access.
4. How much land is required for a solar farm in Malaysia?
A typical 5MW solar farm requires approximately 15 hectares, with most developers preferring 40 acres or more to accommodate infrastructure and buffer zones.
