TOPCon
Latest cell technology
By 2026, all Tier-1 solar brands have transitioned their mainstream product lines to N-type TOPCon. Here's what that means in practice — and why it matters for Malaysian conditions.
PERC (Passivated Emitter and Rear Cell) was the dominant solar panel technology from 2015–2023. It uses P-type silicon with a passivation layer on the rear to reduce recombination losses. PERC panels typically achieve 20–21% efficiency and carry 25-year performance warranties.
In Malaysia, PERC panels installed 5–8 years ago continue to perform well. However, new PERC panels are now largely unavailable from Tier-1 brands — the industry has moved on to TOPCon.
TOPCon (Tunnel Oxide Passivated Contact) adds a thin tunnel oxide layer and doped polysilicon layer on top of the N-type silicon wafer. This dramatically reduces recombination losses at the cell contacts, boosting efficiency to 22–23% while reducing temperature degradation.
For Malaysia specifically, TOPCon's lower temperature coefficient (–0.29%/°C vs PERC's –0.35%/°C) is significant: on a 35°C roof surface, a 10 kWp TOPCon system generates 60–90 kWh more per month than an equivalent-rated PERC system.
Should You Still Buy PERC in 2026?
If a contractor quotes PERC panels at a significant discount, be cautious — it may be old stock, B-grade, or from an unknown brand. In 2026, reputable installers stock TOPCon exclusively. The efficiency and temperature advantages of TOPCon have made PERC obsolete at any comparable price point. Trexon installs TOPCon panels only.
All five brands are Bloomberg NEF Tier-1 rated — meaning they pass the bankability test for financing. The differences below reflect real-world performance data and Malaysian market pricing.

Buyers concerned about supply chain resilience, commercial projects needing IFC-bankable panels, or installers who value consistent global support.
Malaysia Presence
Canadian Solar has regional offices in Southeast Asia and solid distribution in Malaysia. Warranty claims are handled through established local channels.
A brand's local presence affects warranty response times, replacement panel availability, and technical support when you need it most.
| Brand | Regional Office | Malaysia Warehouse/Stock | Service Partners (MY) | Lead Time |
|---|---|---|---|---|
| JinkoSolar | Singapore (SEA hub) | Yes — good stock | Multiple certified installers | 1–2 weeks |
| LONGi | Kuala Lumpur | Yes — strong inventory | Extensive network | 1–2 weeks |
| JA Solar | Singapore (regional) | Moderate stock | Select certified partners | 2–4 weeks |
| Trina Solar | Kuala Lumpur (C&I focus) | Good for C&I projects | Strong in commercial | 2–3 weeks |
| Canadian Solar | Southeast Asia regional | Moderate | Selected EPCs | 2–4 weeks |
Why Local Presence Matters
A 25-year warranty is only as good as the manufacturer's ability to honour it. Choose brands with active Malaysian or Singapore-based offices and certified local service partners. If a brand has no regional presence, claiming warranty panels in year 15 could require shipping to China — effectively rendering the warranty unusable. Trexon only installs panels from brands with established SEA distribution and warranty networks.
Match your situation to the right panel brand — because the 'best' panel depends on your roof, budget, and priorities.
Prioritise efficiency over price. JinkoSolar Tiger Neo or Trina Vertex S+ extracts maximum kWp from limited space.
JA Solar DeepBlue 4.0 gives Tier-1 quality at the lowest RM/W. On a 10 kWp system, saves RM2,000–4,000 vs Jinko.
JinkoSolar's 30-year product warranty is industry-leading. For homeowners planning to stay 25+ years, this matters.
Trina Solar's large-format Vertex S+ maximises kWp on commercial roofs. Canadian Solar for IFC-bankable projects.
LONGi as the world's #1 brand and JinkoSolar as a consistent global leader are both recognised by property valuers.
Higher wattage per panel means your system generates more during peak hours. Jinko 620W or Trina 610W maximises daytime output.
If your roof has shading from trees or adjacent buildings, panel efficiency matters more than usual. Higher wattage per panel means fewer panels, which may help avoid shaded zones. Also consider microinverters or optimisers for partially shaded roofs.
If financing through a bank or green loan, confirm the bank accepts your chosen panel brand. All five brands reviewed here are Bloomberg NEF Tier-1, meaning they pass standard bankability checks for Malaysian green financing products.
An installer who is an authorised partner for a brand gets direct warranty support, priority stock, and technical training. Ask your installer which brands they are authorised partners for — this affects both price and service quality.
If you plan to add battery storage later, ensure your inverter choice supports AC-coupled or DC-coupled battery integration. Huawei, Sungrow, and Growatt all support battery add-ons. Your panel brand is battery-agnostic.
Panels generate DC power; your inverter converts it to usable AC. The right inverter pairing can add 1–3% extra yield through smarter MPPT — and makes monitoring and maintenance easier.

Inverter Brand Matters as Much as Panel Brand
A premium JinkoSolar panel with a budget inverter will underperform compared to the same panel with a quality Huawei or Sungrow inverter. The inverter handles Maximum Power Point Tracking (MPPT) — which continuously optimises the power drawn from your panels throughout the day. A 0.5–1% efficiency difference in inverter MPPT translates to real kWh (and RM) over 25 years.
Both are excellent Tier-1 brands. Jinko wins on warranty (30 years vs LONGi's 25 years) and fractionally higher efficiency. LONGi wins on price and is the world's largest manufacturer by capacity. For most Malaysian homeowners, either brand is a safe choice — the installer quality and system design matter more than the brand difference at this level.
No. Unknown-brand panels may be underpowered (labelled 600W but producing 520W), use inferior cells, and have warranty support that disappears within 5 years. Bloomberg NEF Tier-1 rating exists precisely to separate bankable manufacturers from risky ones. The RM2,000–4,000 you save on panels from an unknown brand can easily be lost in reduced generation over the first 5 years alone.
All solar panels degrade slightly over time — typically 0.45–0.55% per year for TOPCon, giving 88–90% output at year 25. Malaysia's heat does cause thermal derating during peak afternoon hours, but this is accounted for in generation estimates. TOPCon's lower temperature coefficient (–0.29%/°C vs PERC's –0.35%/°C) partially offsets this, making TOPCon the better choice for tropical climates.
SEDA (Sustainable Energy Development Authority) maintains a list of approved solar panel models for the NEM 3.0 scheme. Only SEDA-approved panels qualify for Solar ATAP / NEM connection to TNB's grid. All five brands reviewed here have SEDA-approved models. If a contractor quotes non-SEDA panels, you cannot apply for NEM.
Technically possible but generally not recommended. Mixing different panel wattages or technologies in the same string can reduce overall system performance to the lowest-performing panel in that string. If expanding an existing system, Trexon recommends matching the original panel brand and model where possible, or isolating new panels in a separate string/MPPT.
Trexon's engineers will assess your roof, calculate the optimal system size, and recommend the right panel brand for your budget and goals — then provide a fully itemised quote with brand-specific warranties and projected ROI.
