The adoption of solar energy in Malaysia has experienced a significant transformation, with installation costs for solar photovoltaic (PV) systems decreasing by as much as 50 per cent since 2011. This cost reduction is largely attributed to government initiatives like the feed-in tariff (FiT).
Net Energy Metering (NEM) programs have also created economies of scale. While solar power accounted for only 3.4% of the national electricity supply in 2024, it is projected to potentially supply 39% by 2050, as it has already become the cheapest source of electricity generation in the country.
Cost/price of solar panels in Malaysia
The cost of a residential solar system is largely influenced by system capacity and a household’s overall energy consumption. Smaller homes with lower electricity usage typically require more affordable installations, while larger properties with higher demand need more extensive systems.
Pricing is commonly estimated based on monthly electricity usage to determine the appropriate system size. Households with moderate consumption require mid-sized systems, while higher-usage homes benefit from larger capacities. As energy demand increases, system complexity and investment levels rise accordingly.
Typical Residential Costs by System Size in Malaysia
Small homes
For small homes, residential solar systems typically require around 3kWp capacity, with prices ranging from RM12,000 to RM15,000. These entry-level systems are popular for terraced houses, reflecting significant cost reductions compared to much higher installation prices commonly seen a decade ago.
Average-sized homes
Average-sized homes usually need systems between 4kWp and 6kWp, with costs ranging from RM16,000 to RM24,000. This category suits most urban households, especially those using multiple appliances, where higher-capacity systems near 6kWp accommodate increased electricity consumption efficiently.
Large homes
Larger homes such as semi-detached houses and bungalows often require 9kWp or more, with investments starting at RM28,000 and exceeding RM42,000. These systems typically include SEDA-certified installation, Net Energy Metering applications, and mobile-based monitoring tools for performance tracking.
Factors influencing the pricing of solar panels in Malaysia
System Size (kWp)
System size, measured in kilowatt-peak (kWp), is the primary cost driver of a solar PV system. Larger systems require more panels and higher-capacity components, increasing upfront costs. However, higher kWp systems typically deliver faster returns by offsetting a greater portion of electricity bills.
Panel Type
Solar panel type significantly affects pricing and performance. Monocrystalline panels cost more due to higher efficiency and better low-light performance, allowing more power generation in a limited space. Polycrystalline panels are more affordable but less efficient, requiring larger roof areas to achieve similar energy output.
Inverter Type
Inverter selection also influences system cost. String inverters are the most economical and suitable for roofs with consistent sunlight exposure. Microinverters and power optimisers cost more but improve performance on shaded or complex roofs by allowing each panel to operate independently.
Installation Quality and Complexity
Installation quality and site complexity impact final pricing through labour, mounting systems, and roof requirements. SEDA-certified installers may charge more but ensure compliance, safety, and proper handling of NEM applications. Urban areas often benefit from more competitive pricing than remote or difficult locations.
Brand and Efficiency
Panel brand and efficiency level can significantly affect overall system cost. Premium brands like Jinko, Trina, and Longi offer higher efficiency, advanced technology, and long warranties up to 30 years. Their reliability, performance stability, and after-sales support justify a higher upfront investment for long-term value.
How costs are structured
The cost of a solar PV system is structured around the upfront investment, which includes solar panels, inverters, mounting structures, wiring, and professional installation labour. This initial payment represents the largest portion of the total expense and determines overall system quality and long-term performance.
Another key component is the cost per watt, which varies based on panel technology and efficiency. Monocrystalline panels typically range from RM1.80 to RM2.50 per watt, while polycrystalline panels are more affordable at RM1.40 to RM1.90 per watt, influencing overall system pricing.

FAQS
1. Is installing solar panels in Malaysia worth it?
Yes. With abundant sunlight, rising electricity tariffs, and government programs like Net Energy Metering (NEM), solar panels offer long-term savings and protection against future energy cost increases.
2. How long does it take to recover the cost of a solar system?
Most homeowners recover their investment within several years, depending on system size, electricity usage, and tariff category. Higher energy consumption generally results in faster payback periods.
3. Does roof size or type affect solar installation cost?
Yes. Available roof space, orientation, and shading influence system design and capacity. Complex roofs or limited space may require higher-efficiency panels or advanced inverter solutions, which can affect pricing.
4. What maintenance is required for residential solar systems?
Solar systems require minimal maintenance. Periodic panel cleaning and system checks are recommended to ensure optimal performance, while most components come with long-term warranties.
