Solar Energy Landscape: Market Trends
Malaysia is accelerating its clean-energy push. Solar sits at the centre of new renewable targets, powered by government incentives, affordable financing, and growing demand from homes, businesses and industry.
Government Incentives and Industry Growth
These programmes lower the initial capital outlay and guarantee long-term savings.
- Solar Accelerated Transition Action Programme (Solar ATAP): Launches 1 Dec 2025; keeps energy-offset credits tied to the updated tariff.
- Self-Consumption (SelCo) Scheme: Allows on-site use of all generated solar electricity with no export credits. Domestic capacity limits are 5kW for single-phase and 12.5kW for three-phase systems.
- Green Investment Tax Allowance (GITA): Offers tax incentives for green technology investments, offsetting up to 70% of statutory income.
- Green Technology Financing Scheme (GTFS 4.0): Active until 31 December 2025, it provides 60% government loan guarantee plus a 1.5% interest p.a. for up to 7 years.
What to Look for When Choosing Solar Providers
Picking the right installer determines your system’s performance and lifespan.

Top Solar Panel Brands in Malaysia: Performance Guide
Your panel choice determines decades of output. Pick high-efficiency models engineered to thrive in Malaysia’s heat and humidity.
Which Panels Work Best in Tropical Climates
Malaysia’s climate requires robust modules. Look for panels with:
- Low-Temperature Coefficient: This determines how much the panel's efficiency drops as its temperature increases. A lower coefficient means better performance in high Malaysian heat.
- PID Resistance (Potential-Induced Degradation): Resistance to voltage-related power loss caused by the local heat and humidity.
- Tier-1 Status: Panels from manufacturers like JA Solar—listed in the Bloomberg New Energy Finance (BNEF) Tier 1 list—are highly bankable, ensuring your project meets financing requirements.
Price-Performance Analysis of Leading Brands
Global Tier-1 brands lead Malaysia’s market by pairing solid warranties with proven output:
- JA Solar: Top-performing Tier-1 brand known for high-efficiency mono PERC panels that deliver consistent power in Malaysia’s tropical climate. Trusted for both commercial and residential installations due to their excellent reliability, strong warranties, and long-term value.
- LONGi Solar: High-efficiency mono PERC panels at mid-range prices; strong value for homes and C&I rooftops.
- JinkoSolar/Trina Solar: Cost-effective Tier-1 choices; durable output ideal for budget-sensitive large installations.
Residential vs Commercial Solar Installation
Solar for a home or office block varies in system size, permitting needs, and financing structure.
Finding the Right System for Your Property
Match the system to your energy needs, roof or land space, and goal.
- Homes: 4–12 kW arrays fit most roofs, sized to daily usage and budget.
- Businesses: Installations run from tens of kW to several MW, set by daytime load and available roof or ground area.
Installation Process and Timeline Expectations
For both sectors, the professional solar installer manages most of the technical and administrative work.
- Site Audit & Design: Engineers assess your roof, shading, and energy use to finalise system size and layout.
- Permitting & Approval: The provider lodges all required applications with TNB, SEDA, and local authorities.
- Installation: Crews mount panels, inverters, and wiring. Small homes finish in days, larger roofs take longer.
- Commissioning: TNB inspects, fits the bi-directional meter, and switches the system on, so savings start right away.
