Malaysia’s solar landscape is expanding quickly as more homeowners and businesses recognise the long-term benefits of clean energy. Yet, not all solar panels perform equally in the country’s hot and humid environment. Drawing on over four decades of experience in construction supply, Unitrade brings reliability and proven quality to renewable energy through solar.unitrade.com.my — featuring high-efficiency panels built for Malaysia’s real-world conditions.
Why performance matters in Malaysia’s environment
The Malaysian climate is both a blessing and a challenge for solar energy. Abundant sunlight means strong energy potential, but consistent heat, humidity, and seasonal rainfall can reduce a panel’s long-term yield. High temperatures often cause ordinary panels to lose output as cell efficiency drops under stress.
Panels chosen by Unitrade are tested for these factors, with a low temperature coefficient that keeps performance stable even during mid-day peaks. Each module is engineered for tropical durability, allowing homes and facilities to harvest steady energy all year round.
Unitrade’s solar innovation in focus
Unitrade’s solar portfolio is designed around the idea of local performance. Every panel integrates advanced cell technology, anti-corrosion framing, and internationally certified components. Together, these features create systems that are practical for Malaysia’s rooftops — from urban houses to commercial buildings.
Two flagship models define the range: Astro N5 and Astro N7. Both use N-type cell technology for high conversion efficiency and reduced degradation, yet each serves a distinct purpose within Malaysia’s growing renewable sector.
ASTRO N5: High-performance solar panel for broad deployment
Astro N5 is Unitrade’s next-generation, high-output panel for Malaysia’s grid. Suited to utility-scale systems and commercial rooftops seeking long-term energy savings, with flexibility for residential PV.
The N5 solar panels balances compact form factor, high output, and durability, making it a strong choice for C&I rooftops and scalable residential deployments where footprint, yield, and long-term cost control must be managed together.
Key specifications
- Power range: 625 W to 650 W
- Maximum module efficiency: 23.3%
- Product warranty: 15 years
- First-year power degradation: ≤ 1.0%
- Annual degradation (Year 2–30): ≤ 0.4%
- Application scenarios: Utility-scale, C&I rooftops, and residential PV systems
Engineering and features
- TOPCon 4.0 cell technology: Upgraded low-corrosion paste and POML improvements elevate conversion efficiency by about 0.3 to 0.5 percentage points versus prior models, lifting energy yield per square metre.
- Super multi-busbar (SMBB) design: Increased solder strip density improves conductivity and light capture, reducing resistive losses across the cell surface.
- Higher bifaciality rate: Rear-side gain boosts total output on reflective rooftops and ground surfaces.
- 183R large-format silicon wafers: Around 15.6 percent more active area than 182 mm wafers, enabling higher panel wattage, better container loading efficiency, and lower per-watt installation costs.
- Cost efficiency: Compared with standard PERC panels, N5 supports lower BOS and LCOE for stronger long-term returns.
ASTRO N7: High-efficiency panel for utility-scale and distributed power
Unitrade Astro N7 panels are high-output photovoltaic solar panels engineered for utility-scale farms and distributed power stations in Malaysia. Integrates advanced module architecture for consistent field performance.
The N7 solar panels are tuned for projects prioritising bankable, high-density generation at scale. Its combination of output, low degradation, and low-light capability is well-suited to utility parks and large distributed installations targeting consistent lifetime yield.
Key specifications

Engineering and features
- TOPCon 4.0 cell technology: Low-corrosion paste and POML enhancements improve conversion efficiency by about 0.3 to 0.5 percentage points, supporting stable, high-yield output.
- Enhanced low-light performance: Designed to maintain production under haze, cloud cover, or low-angle sun typical in Southeast Asia.
- Super multi-busbar (SMBB) design: More ultra-fine solder strips improve current flow and light absorption, increasing power density.
- Rectangular silicon wafers: Around 15.6 per cent more active area than standard 182 mm cells, raising panel wattage and optimising space utilisation on roofs and in containers.
- Versatile deployment options: Corrosion-resistant materials and flexible system compatibility support long-term use in both ground-mount and C&I rooftop environments.
Efficiency, yield, and long-term savings
Module efficiency determines how much of Malaysia’s strong irradiance is converted into electricity per square metre. Both N5 and N7 pair high conversion efficiency with low degradation profiles, so systems retain more of their initial capacity year after year. That stability supports predictable production and strengthens the case for long-term energy savings under prevailing tariff settings and incentive frameworks.
Durability and lifecycle confidence
Panels must endure mechanical loads, moisture, and corrosive environments across decades. The ASTRO series incorporates bifacial glass, corrosion-resistant framing, and multi-busbar layouts that help mitigate micro-cracks and resist power loss over time. Low first-year degradation and a tight annual degradation rate from Year 2 to Year 30 underpin dependable lifecycle output.
Deployment scenarios in Malaysia
- Residential: Compact arrays that still deliver robust output, aided by bifacial gain on light-coloured or reflective surfaces.
- Commercial and industrial rooftops: High-density generation to offset daytime loads, with panel formats and wafer sizes that improve container loading and reduce installed cost per watt.
- Utility-scale and distributed power: Field-proven architectures that scale predictably, maintain production in low-light windows, and support long-term operational targets.
How Unitrade supports projects
Unitrade couples its panel range with practical project support, including guidance on product selection for site conditions and system objectives. The goal is straightforward: help Malaysian projects deploy durable, efficient arrays that keep producing at a high level over time.
Conclusion
Unitrade’s ASTRO N5 and ASTRO N7 panels combine TOPCon 4.0 innovation, bifacial energy capture, and module designs that target efficiency, cost effectiveness, and field durability. With low degradation and strong warranty cover, they are built for Malaysia’s conditions and the country’s long-term energy goals.
