How Much Does Commercial Solar Cost in Malaysia?
Commercial solar costs in Malaysia depend on the system capacity, roof condition, equipment specification, electrical connection, structural work, site access, monitoring, application requirements and financing model. Larger and simpler rooftop projects may achieve a lower cost per kWp, while smaller or technically complex installations may cost more.
What Is the Commercial Solar Price Range in Malaysia?
For preliminary budgeting in 2026, many straightforward commercial rooftop solar projects may fall within an indicative range of approximately RM2,500 to RM4,500 per kWp.
This broad range is intended for early planning only. It should not be treated as a guaranteed market rate because every commercial property has different roof, structural, electrical, application and operational conditions.
Smaller Commercial Systems
Smaller projects may have a higher cost per kWp because design, application, mobilisation, monitoring and project-management costs are spread across less capacity.
Larger Rooftop Systems
Larger projects may obtain economies of scale when the roof, electrical connection and installation access are straightforward.
Complex Commercial Sites
Projects involving structural reinforcement, high-voltage systems, long cable routes or restricted access may exceed the typical range.
Solar with Battery Storage
Battery storage should be priced separately because its cost depends on usable energy capacity, power output, controls, backup scope and operating strategy.
Estimated Commercial Solar Cost by System Size
The following table provides broad planning estimates based on an indicative purchased-system range of RM2,500 to RM4,500 per kWp. Individual quotations may fall below or above these figures.
| System Capacity | Indicative Cost Range | Possible Facility Type | Important Note |
|---|---|---|---|
| 20 kWp | RM50,000–RM90,000 | Small office, shop, clinic or small commercial building | Smaller projects may carry a higher cost per kWp. |
| 50 kWp | RM125,000–RM225,000 | SME premises, warehouse, school or retail outlet | Roof, connection and access conditions remain important. |
| 100 kWp | RM250,000–RM450,000 | Factory, hotel, commercial building or larger warehouse | Structural and electrical assessment may affect the final cost. |
| 200 kWp | RM500,000–RM900,000 | Medium industrial or institutional facility | Technical-study and connection requirements should be confirmed. |
| 500 kWp | RM1.25 million–RM2.25 million | Large factory, logistics centre or industrial property | Economies of scale may be offset by structural or high-voltage work. |
| 1,000 kWp | RM2.5 million–RM4.5 million | Large industrial or commercial facility | Solar ATAP capacity remains subject to the applicable technical assessment and project conditions. |

| Hybrid Structure | Varies | Depends on the agreed structure | Allocation of equipment, energy, financing, maintenance and end-of-term rights. |
How Long Is the Payback Period for Commercial Solar?
There is no fixed commercial solar payback period. The result depends on project cost, solar generation, direct self-consumption, electricity tariffs, operating hours, financing, maintenance and equipment replacement assumptions.
A provider may present an estimated simple payback by dividing the net project cost by the estimated annual electricity-cost reduction. However, this simplified calculation may not reflect financing costs, degradation, maintenance, downtime, tax treatment or future equipment replacement.
- Total installed cost
- Annual solar generation
- Daytime self-consumption percentage
- Surplus electricity treatment
- Current electricity tariff
- Maximum Demand implications
- Future tariff assumptions
- System performance degradation
- Inverter replacement allowance
- Annual maintenance cost
- Insurance cost
- Financing interest and fees
- Tax and accounting treatment
- System downtime
- Roof-removal obligations
- Contract escalation where applicable
