Top 10 Challenges to Solar Panel Installation for SMEs in Malaysia (2025)

Malaysia receives strong year-round sunlight, yet the rate of solar panel installation remains lower than expected. Businesses interested in clean energy often find the process more complicated than anticipated.

The reality is that solar adoption in Malaysia is shaped by cost pressures, technical barriers and layers of regulation that vary by council and region. These challenges make installation slower, more expensive or less predictable, especially for SMEs and commercial buildings.

This guide presents the ten most important challenges to solar power implementation in Malaysia, supported by academic and industry insights. 

Main Challenges

Selection Criteria for the Top 10 Challenges

These challenges were prioritised based on:

• Repeated mention across Malaysian research and industry reports (Source: Taylor’s University; UPM; Planning Malaysia Journal)
• Direct impact on solar panel installation timelines
• Influence on business-level adoption decisions
• Technical and administrative depth of the barrier

1. High Upfront Installation Costs

Solar panels have become cheaper globally, but installation costs in Malaysia remain heavy for businesses.

Key issues include:

• Capital outlay for panels, inverters and wiring
• Additional expenses for structural reinforcement
• Engineering, design and approval fees
• Payback period of roughly three to seven years for many well-sized commercial systems, depending on tariffs, usage profile and financing model

Businesses with limited cash flow often postpone installation due to budget constraints, even when the long-term savings on solar energy are attractive. (Source: Taylor’s University; Planning Malaysia Journal)

2. Low Commercial Awareness and Misunderstanding of Solar Benefits

Many business owners underestimate modern solar technology or overestimate risks.

Common misunderstandings include:

• “Solar panels cannot support industrial equipment.”
• “Roofs are too weak for mounting structures.”
• “Solar requires constant maintenance and causes frequent breakdowns.”
• “Installation will disrupt operations for long periods.”

Awareness of financing options such as SARE arrangements, leasing and power purchase agreement (PPA) models is also low. As a result, many businesses assume solar requires a large cash payment upfront, when in reality there are ways to shift or spread the capital cost. (Source: UPM; Planning Malaysia Journal)

3. Grid Capacity Constraints and Technical Bottlenecks

The Malaysian grid is uneven in its ability to support solar feed-in, especially as more systems connect over time.

Typical challenges include:

• Transformer capacity limits in certain areas
• Ageing substations in older districts
• Restrictions on large systems in industrial zones
• Delays due to required grid or connection impact studies

These bottlenecks can force system downsizing, redesign or phasing. For businesses, this may mean a smaller-than-planned system or a longer overall project schedule. (Source: Taylor’s University)

4. Slow Approval Processes and Complex Regulations

Solar panel installation involves multiple authorities, which introduces inconsistency and delay.

Businesses often face:

• Varying requirements from different local councils
• Multiple rounds of document submissions and revisions
• Slow responses or updates from agencies and utilities
• Long lead times for approval, testing and commissioning

This slows installation and affects project planning. Without experienced partners, businesses may struggle to track which documents, drawings and certifications are needed at each stage. (Source: Taylor’s University; UPM)

5. Electricity Tariff Structure and Fossil Fuel Subsidies

Malaysia’s electricity tariffs have historically been kept relatively low by long-standing fuel and electricity subsidies. Even though base tariffs for 2025–2027 are rising, many users still benefit from targeted subsidies that cushion their effective rates.

Impact on solar economics:

• Keeps grid electricity cheaper than its full cost, which can reduce the financial attractiveness of solar for some users
• Can lengthen payback periods for commercial systems, especially where most consumption happens outside peak solar hours
• Slows adoption for businesses operating primarily at night or with highly variable loads
• Remains a structural and financially significant barrier, although gradual subsidy rationalisation is improving solar’s competitiveness over time (Source: Taylor’s University)

6. Limited Energy Storage Options

Energy storage remains a challenge due to cost and technical readiness, especially for larger commercial systems.

Issues businesses face include:

• High cost of lithium-ion and newer battery technologies at commercial scale
• Limited installer expertise in large-scale or complex storage configurations
• Difficulty relying on solar alone for uninterrupted operations in the absence of a robust battery system
• Uncertainty around battery lifespan, replacement cost and disposal

Without affordable and trusted storage, most solar installations remain grid-dependent and cannot fully replace backup generators or grid supply for critical loads. (Source: Taylor’s University; UPM)

7. Technical or Structural Limitations of Existing Buildings

Older buildings often require modifications before solar can be installed safely and cost-effectively.

Typical limitations include:

• Weak, corroded or aged roofs that cannot safely support mounting structures
• Incompatible roofing materials that complicate mounting
• Shading from nearby buildings, trees or rooftop equipment
• Insufficient electrical wiring capacity or outdated switchboards

These issues add complexity and cost to installation planning. They can also reduce system performance if shading or layout constraints are not handled properly. (Source: Taylor’s University)

8. Insufficient Business Financing Pathways

SMEs in particular face difficulty obtaining attractive financing arrangements for solar projects.

Common hurdles:

• Higher interest rates for some green or asset-backed loans
• Limited PPA adoption due to lack of awareness or comfort with the model
• Leasing structures that are not widely marketed or tailored to SMEs
• Slow and documentation-heavy banking processes for solar-related credit applications

This financing gap slows commercial solar adoption, even for businesses that could benefit from immediate bill savings. (Source: Planning Malaysia Journal)

9. Bureaucratic Fragmentation and Inconsistent Implementation

Malaysia’s regulatory landscape varies by state, council and sometimes by type of building.

Businesses frequently encounter:

• Different documentation lists for similar types of projects
• Different safety and fire certification requirements
• Different architectural or aesthetic standards for rooftop installations
• Changing incentive scheme rules that affect payback calculations

This inconsistency creates uncertainty and puts more pressure on businesses to choose installers who understand local procedures and keep up with policy updates. (Source: Taylor’s University; UPM)

10. Shortage of Skilled Installers and Technicians

Demand for solar installation is growing faster than the supply of trained workers in some regions.

Key issues include:

• Longer waiting times to start new projects, especially for larger systems
• Limited technician availability outside major cities and industrial hubs
• Slower maintenance response times when faults occur
• Higher risk of poorly executed installations if unqualified contractors are engaged

This affects both installation timelines and long-term system performance, especially for businesses in non-urban or remote locations. (Source: Taylor’s University)

Summary of Pressing Challenges

Malaysia’s solar challenges fall into four dominant areas:

1. Financial Barriers

• High upfront costs for panels, inverters and structural works
• Limited and sometimes complex financing options for SMEs
• Tariff and subsidy structures that can weaken the return on investment for some users

2. Regulatory Barriers

• Slow approvals due to multi-agency involvement
• Fragmented procedures across states and councils
• Inconsistent enforcement and evolving programme rules

3. Technical Barriers

• Grid limitations and connection capacity constraints
• Structural issues, especially in older buildings
• Costly and less mature storage options for full energy independence

4. Awareness and Operational Barriers

• Misunderstandings about solar performance and reliability
• Unfamiliarity with financing models such as leasing and PPAs
• Maintenance and technician shortages affecting long-term performance

Most businesses do not face just one barrier. They often face several at the same time, making careful planning and partner selection essential.

Conclusion

Malaysia has strong solar potential but also faces practical challenges related to cost, regulation, grid capability and building conditions. These barriers affect installation timelines, financial decisions and long-term solar viability for businesses.

Despite the challenges, solar panel installation is not only feasible in Malaysia; it is increasingly strategic for businesses that want lower operating costs, better energy resilience and stronger sustainability credentials over the long term.
