Key Takeaways
Malaysia’s renewable energy targets have made utility-scale solar one of the fastest-growing parts of the country’s energy sector. Ray Go Solar, a Malaysia-based solar engineering, procurement, and construction company with more than 13 years of experience, sees growing interest from businesses trying to understand how these larger projects differ from the rooftop systems most companies install.
Unlike a rooftop system on a factory or home, a solar farm is a large, standalone power generation asset, developed through a formal bidding process and connected directly to the national grid.
A solar farm, also called a utility-scale or large-scale solar project, is a ground-mounted or floating solar installation built to generate electricity for sale to the grid or a corporate buyer, rather than to power a single building.
In Malaysia, these projects are generally developed under the Large Scale Solar (LSS) programme administered by the Energy Commission, now in its fifth competitive bidding round.
LSS5, opened for bidding in 2024, targets a total capacity of 2,000MW and is structured across several packages by project size and type: smaller packages generally cover ground or rooftop plants from around 1MW up to 30MW, a larger package covers plants from 30MW up to 500MW, and a separate package is reserved for floating solar plants. Some packages carry Bumiputera ownership or SME eligibility requirements.
Selected developers enter into a Power Purchase Agreement, selling electricity generated directly to the national grid over a fixed contract term, with projects awarded through competitive bidding aimed at driving down the Levelized Cost of Energy.
Alongside utility-scale LSS projects, Malaysia runs separate schemes for rooftop and smaller installations. As of 1 January 2026, Solar ATAP (Solar Accelerated Transition Action Programme) replaced the earlier Net Energy Metering (NEM) scheme as the national rooftop solar framework, under guidelines issued by the Energy Commission and administered by SEDA Malaysia.
Unlike NEM, which operated under a fixed national capacity quota that led to waiting lists, Solar ATAP is generally open on a first come, first served basis with no national capacity ceiling. It runs on a self-consumption-first model, meaning a property uses the solar power it generates first, with only surplus exported to the grid; domestic systems are generally capped at 5kW for single-phase or 15kW for three-phase connections, while non-domestic systems can generally reach up to 100% of the premises’ Maximum Demand. Exported surplus is credited based on the energy charge component of the applicable tariff for domestic consumers, or the Average System Marginal Price for non-domestic consumers, generally for a programme duration of up to 10 years.
Self-Consumption (SELCO), by contrast, requires no scheme enrolment and involves no export to the grid at all, with the solar system sized purely to offset the building’s own consumption.
Before a solar farm project can proceed, developers must secure a site that meets several practical requirements: enough contiguous land for the target capacity, flat and unshaded terrain, and proximity to an existing TNB transmission substation, since distance from the grid significantly affects connection cost. Land is typically zoned for industrial use, though some states have introduced special allowances for agricultural land to be used for solar development over a fixed term.
Two main types of solar farm are found in Malaysia: ground-mounted systems, the most common type, and floating solar farms installed on lakes, reservoirs, or former mining pools, which conserve land and can reduce water evaporation.
Development costs for a utility-scale solar farm in Malaysia are commonly reported in the range of RM3 million to RM4 million per megawatt, though the final figure depends heavily on land cost, grid connection distance, equipment selection, and financing terms, and should be treated as a general planning benchmark rather than a fixed number.
Construction itself is relatively quick once financing and permits are in place, typically taking 6 to 12 months to reach commercial operation.
Cost Factor | Typical Range or Consideration |
|---|---|
Development cost per MW | Commonly reported around RM3 million to RM4 million |
Construction timeline | 6 to 12 months |
Operational lifespan | Commonly cited at 21 to 25 years |
Maintenance | Generally low intensity in Malaysia’s climate |
Most utility-scale solar projects in Malaysia are financed through a Power Purchase Agreement, where the developer or an investor funds construction and the buyer, whether the national grid or a corporate offtaker, pays for the electricity generated over the life of the contract. This structure allows businesses to access solar power without upfront capital investment, a model that businesses evaluating commercial and industrial solar at a smaller scale will recognise, since PPA-style financing is also common for rooftop C&I systems. A second model, land leasing, allows landowners to earn income over a long-term lease by leasing suitable land to a solar developer without investing in the infrastructure themselves.
A utility-scale solar farm generally moves through several stages: a feasibility study assessing site suitability and grid capacity, participation in an LSS bidding round or negotiation of a corporate PPA, securing financing and permits, construction and grid connection testing, and commercial operation, which is commonly cited at 21 to 25 years before major components reach end of life. At decommissioning, the process generally involves disconnecting from the grid, removing infrastructure, and restoring the land.
Costs are commonly reported around RM3 million to RM4 million per megawatt, though this varies based on land, grid connection distance, and financing structure, and should be confirmed with a current feasibility study.
LSS is a competitive bidding programme for utility-scale solar farms selling power to the grid, Solar ATAP is the current national rooftop scheme allowing systems to export surplus power for bill credits with no capacity quota, and SELCO allows on-site generation for self-consumption with no grid export and no scheme enrolment.

Utility-scale solar installations are commonly cited as having an operational lifespan of around 21 to 25 years, though this depends on equipment quality and maintenance.
Utility-scale solar farms suit large landowners, independent power producers, and corporations with the scale to participate in LSS bidding rounds or negotiate a standalone PPA. For most businesses looking to reduce electricity costs rather than develop a standalone power generation asset, a commercial or industrial rooftop system, sized under Solar ATAP or SELCO, is typically a faster and more accessible route to solar savings.
Ray Go Solar designs commercial and industrial solar PV systems for factories, warehouses, and offices, alongside battery energy storage solutions for businesses that want to maximise the value of their solar investment.

Programme quotas and package structures for schemes like LSS and Solar ATAP are updated periodically, so figures here should be confirmed against the latest SEDA and Energy Commission announcements before making investment decisions.
