Best Solar Panels in Malaysia (2026): 4 Top Brands

Key Takeaways:
The best solar panels for Malaysian homes in 2026 are n-type panels from brands on BloombergNEF's Tier 1 list. AIKO's 655 W Stellar leads on efficiency (24.2%) and heat tolerance, while JA Solar, Trina and LONGi offer 620–630 W TOPCon panels at 23.0–23.3%, all with 30-year power warranties. Buy them as a complete system through an installer who handles your Solar ATAP application, not as loose panels.

Search for solar panels in Malaysia and you'll find dozens of brands, hundreds of models and quotes that differ by RM10,000 for the same roof. The brand name matters less than most quotes suggest. The panel type, wattage and warranty matter more.

Residential panels have also changed fast. Most panels going onto Malaysian roofs in 2026 produce 590–655 W each, and older p-type PERC panels are on their way out.

This guide compares the four panel brands GetSolar installs in Malaysia, the inverters that pair with them, and how to buy solar the right way. We install all four, so we're not a neutral party. That's why we've shown how we compared them and the datasheet figures behind every number.

What Are the Best Solar Panel Brands in Malaysia in 2026?

The strongest options for Malaysian homes are AIKO, JA Solar, Trina Solar and LONGi. All four appear on BloombergNEF's Tier 1 list, all use n-type cells, and all back their panels with a 30-year power warranty:

Sources: AIKO, JA Solar, Trina Solar and LONGi datasheets. All four panels measure 2382 × 1134 mm, so their efficiency figures compare like for like.

All four panels share the same frame size, so the difference comes down to how many watts each one squeezes from the same space. On a roof that fits 10 panels, AIKO gives you 6.55 kWp against 6.25 kWp for Trina.

How We Compared These Solar Panels

We compared each panel on five things that matter for a Malaysian landed home over 25 years:

Note: there's no single winner. Each panel below gets a "best for" pick based on these criteria, using manufacturer datasheets and Kiwa PVEL's 2026 Scorecard.

AIKO Stellar: Best for Maximum Power

AIKO's Stellar is the most efficient panel GetSolar offers in Malaysia, at 24.2% and 655 W per panel. It uses all-back-contact (ABC) cells, which move every wire to the back of the cell so nothing shades the front.

The Stellar also handles heat best of the four, losing 0.26% of output for every °C above 25°C. AIKO caps first-year degradation at 1% and later years at 0.35% per year, backed by a 15-year product warranty and a 30-year performance warranty.

AIKO is on BloombergNEF's Tier 1 list and earned Top Performer status for its back-contact panels in Kiwa PVEL's 2026 PV Module Reliability Scorecard.

The trade-off: AIKO costs more per watt, so it pays off most where roof space is limited.

Best for: small terrace roofs, partly shaded roofs, and homeowners who want the most output per panel.

JA Solar: Best All-Rounder for Most Homes

JA Solar's JAM66D45 is one of the most common panels on GetSolar's Malaysian quotes, delivering up to 630 W at 23.3% efficiency. It uses n-type TOPCon cells in a bifacial, dual-glass build.

The 630 W model loses 0.29% per °C in heat, carries a 12-year product warranty, and guarantees 87.4% of its rated output at year 30. A 590 W version is also available, with slightly different warranty terms, so check the datasheet for the exact model on your quote.

JA Solar is on BloombergNEF's Tier 1 list and has been a Top Performer in Kiwa PVEL's Scorecard for 11 years, including 2026.

The trade-off: its efficiency sits a step below AIKO's back-contact panel.

Best for: most landed homes, where strong, proven output matters more than squeezing out every last watt.

Trina Solar Vertex N: Best for Proven Reliability

Trina has been a Top Performer in every edition of Kiwa PVEL's PV Module Reliability Scorecard, 12 consecutive years including 2026, the longest streak of the four brands here. Its Vertex N panel delivers 625 W at 23.1% efficiency using n-type i-TOPCon cells.

The Vertex N loses 0.29% per °C, carries a 12-year product warranty and guarantees 87.4% output at year 30.

Trina also runs its Asia Pacific headquarters from neighbouring Singapore, which keeps regional support close.

The trade-off: it offers no output edge over JA Solar at a similar wattage.

Best for: homeowners who prioritise a long independent testing record.

LONGi Hi-MO 7: Best for Manufacturer Strength

LONGi is one of the world's largest solar manufacturers, shipping 86.58 GW of panels in 2025, and Wood Mackenzie ranked it first of 48 manufacturers in its 2026 module manufacturer ranking. It is on BloombergNEF's Tier 1 list and was named a Top Performer in Kiwa PVEL's 2026 Scorecard.

The Hi-MO 7 uses LONGi's HPDC cells, an n-type TOPCon design. The 620 W model reaches 23.0% efficiency and loses 0.28% per °C, slightly better in heat than JA Solar and Trina. It carries a 12-year product warranty, a 30-year power warranty and 0.4% annual degradation.

The trade-off: at 620 W, its efficiency trails AIKO's back-contact panel.

Best for: buyers who value the backing of the industry's biggest names.

How Do These Panels Handle Malaysian Heat?

Every panel is rated at 25°C, but rooftop cells in Malaysia often run 30–40°C hotter. Here's how much output each panel gives up at a 65°C cell temperature:

Calculation: (65°C − 25°C) × temperature coefficient, using each manufacturer's datasheet figure.

The gap between the four n-type panels is small. The real difference is against older PERC panels, which lose 2.4 to 3.6 percentage points more output on a hot afternoon.

Which Inverter Brands Pair With These Panels?

Your inverter converts the DC power from your panels into AC power for your home, and it decides whether you can add a battery later. GetSolar installs four inverter brands in Malaysia:

A hybrid inverter connects to a battery now or later, so you won't need a second inverter if you add one. Under Solar ATAP, single-phase homes cap at 5 kWac and three-phase homes at 15 kWac, so your supply type also shapes which inverter fits. If evening usage drives your bill, see whether a solar battery pays back.

Where Can You Buy Solar Panels in Malaysia?

The best place to buy solar PV panels in Malaysia is a solar installer or supplier that sells them as a complete, installed system, not as loose panels. Your installer designs the system, supplies the panels and inverter, handles the Solar ATAP application, and coordinates TNB's inspection and meter change before your system connects to the grid. Buying panels alone leaves all of that to you.

You can pay outright, spread the cost with a green loan, or choose Rent-to-Own with little to no upfront cost. Our solar panel price list breaks down what each option and system size costs.

How Do You Choose a Solar Company in Malaysia?

The installer matters as much as the panel brand. Before you sign, make sure the quote names the exact panel and inverter models, explains who handles warranty claims in Malaysia, and covers the Solar ATAP application and TNB grid connection. Our checklist of questions to ask before signing a solar quote covers the rest.

What About Other Solar Panel Brands in Malaysia?

You'll also see Jinko Solar, Canadian Solar, REC and Qcells on Malaysian quotes. Jinko and Canadian Solar make Tier 1 n-type panels comparable to the four above. REC's heterojunction panels, made in Singapore, and Qcells sit at a premium price point.

We focus on AIKO, JA Solar, Trina and LONGi because our installation partners stock them and handle warranty claims locally. A strong brand only helps if someone in Malaysia stands behind it.

Frequently Asked Questions

What is the best solar panel brand in Malaysia?

AIKO, JA Solar, Trina Solar and LONGi are the strongest choices for most homes. All four appear on BloombergNEF's Tier 1 list and use n-type panels with 30-year power warranties. AIKO leads on efficiency, while Trina has the longest Kiwa PVEL Top Performer record.

Which solar panel is the most efficient in Malaysia?

Among the panels GetSolar installs, AIKO's 655 W Stellar is the most efficient at 24.2%. It uses back-contact cells with no wiring on the front.

Are Tier 1 solar panels better?

BloombergNEF's Tier 1 list reflects bankability: whether lenders will finance large projects using a manufacturer's panels. It isn't a quality rating, so pair it with independent test results, such as Kiwa PVEL, for the exact model you're quoted.

How long do solar panels last in Malaysia?

Quality panels produce power for 25 to 30 years or more. All four brands above back their panels with a 30-year power warranty, so check the year-30 output figure on your exact model's datasheet.

Where can I buy solar panels in Malaysia?

Buy them as an installed system through a solar installer who handles the Solar ATAP application and TNB grid connection, rather than buying loose panels.

How much do solar panels cost in Malaysia?

A 5 kWp system costs around RM17,000 installed, according to our solar panel price list. Single-panel prices don't add up to a system quote, because the inverter, wiring, installation and approvals make up much of the cost. See our full solar system cost guide for budgets by house type.

The Best Panel Is the One Matched to Your Roof

All four brands here make excellent n-type panels, so the right choice depends on your roof size, shading and budget. A small terrace roof gains most from AIKO's extra watts, while JA Solar, Trina and LONGi deliver strong output at a lower cost per watt for most homes.
