With a large number of SEDA-registered installers competing for your business, choosing the right solar company in Malaysia has never been more important — or more confusing. A system with a 30-year panel performance warranty means you're not just buying solar panels; you're entering a long-term relationship with an engineering firm. Get it wrong and you could face voided warranties, failed TNB Solar ATAP applications, or a system that underperforms for its entire lifespan.
This guide does not rank installers. We are a solar company ourselves, and we cannot verify installation counts, review scores or prices for other companies. Instead it gives you ten criteria to compare any installer, including us, so you can check each one yourself.
Top 10 Criteria for Comparing Solar Companies in Malaysia
1. SEDA RPVSP registration
Only a SEDA Registered PV Service Provider (RPVSP) can submit your Solar ATAP application. Ask for the registration number and check it on the SEDA website before you sign anything.
2. A detailed written quotation
The quote should name the exact panel and inverter models, the expected monthly output, every warranty period, who handles the Solar ATAP application and TNB commissioning, and the total turnkey price including permits.
3. Warranties stated separately
Ask for panel product, panel performance, inverter and workmanship warranties in writing, each with its own period. The workmanship warranty covers roof leaks and wiring defects, so it matters most day to day.
4. After-sales support and monitoring
Ask how a fault is reported, who attends, and whether a monitoring app is included so you can see output from the first day.
5. Panel and inverter brands
Ask for Bloomberg Tier 1 panels and an established inverter brand, and confirm the model numbers on the quote.
6. Pricing transparency
Compare published prices or itemised quotes against vague "contact for quote" offers. Divide the total by system size to get RM per Wp, and ask what is included.
7. Payment and financing options
Check which routes are offered (cash, card instalments, bank loan, rent-to-own, business hire purchase) and what is due up front. Read any booking or deposit terms before you pay.
8. Service area and delivery model
Check whether the company installs in your area itself or through partners, and who you deal with after installation.
9. Track record you can verify
Ask for references and completed-project addresses you can contact, and read recent Google reviews yourself rather than relying on a company's own claims.
10. Fit for your project
Some companies focus on homes, others on factories and utility-scale projects. Match the installer to your size, and understand whether you will own the system or only buy its electricity.

Solar Panel Price Comparison 2026
One of the biggest frustrations when researching solar companies in Malaysia is the lack of published pricing. Based on current market data, here is what to expect for a Tier-1 system turnkey installed in 2026:
| System Size | House Type | Trexon Price | Monthly Savings Est. | Payback Period |
|---|---|---|---|---|
| 5.58 kWp | Small terrace | RM 15,999 – RM 20,999 | about RM 143 (RM 200 bill) | 9.3 years |
| 7.44 kWp | Intermediate terrace | RM 17,999 – RM 22,999 | about RM 291 (RM 500 bill) | 5.2 years |
| 9.92 kWp | Corner lot / semi-D | RM 23,999 – RM 28,999 | about RM 373 (RM 700 bill) | 5.4 years |
| 11.78 kWp | Bungalow | RM 25,999 – RM 30,999 | about RM 610 (RM 1,000 bill) | 3.6 years |
| 30 kWp | SME / shophouse | RM 72,000 + SST (RM 2,400/kWp) | about RM 1,600 (Low Voltage tariff) | about 3.8 years |
| 100 kWp+ | Factory / warehouse | RM 2,400/kWp + SST | about RM 3,100 per 100 kWp (MV General) | about 6.4 years (MV) |
Trexon catalogue prices (Solis to Sungrow inverter). Home savings: estimate on the RP4 domestic tariff (from 1 Jul 2025), before AFA, the 1.6% RE Fund and service tax; 3.5 sun-hours a day; about 40% of solar used at home and the rest exported and credited at the 27.03 sen Energy Charge (capped at what you import) for 10 years under Solar ATAP; payback uses the Solis price. Commercial rows: all output used on site, no Maximum Demand saving counted.
Note: Prices are all-inclusive turnkey and include the Solar ATAP application. Solar ATAP is a bill credit programme — it does not reduce the upfront system cost. Use the Trexon savings calculator to see your payback period and lifetime savings.
How to Choose the Right Solar Company in Malaysia
With many registered solar companies in Malaysia, narrowing the field requires a systematic approach. Here is what matters most:
Step 1: Verify SEDA RPVSP Registration
Every solar installer in Malaysia must be registered with SEDA (Sustainable Energy Development Authority) as a Registered PV Service Provider (RPVSP). An unregistered solar company cannot legally submit your Solar ATAP application to TNB. Ask for their SEDA registration number and verify it at seda.gov.my before signing anything.
Step 2: Check Workmanship Warranty Length
Panel performance warranties of 25–30 years are common across the industry (the panels Trexon installs carry 30 years). The real differentiator is the workmanship warranty — this covers roof leaks, wiring defects, and installation failures. Trexon offers 5 years. Ask any installer for their workmanship warranty in writing.
Step 3: Demand a Detailed Written Quotation
A trustworthy solar company in Malaysia will provide a written quote specifying: exact panel brand and model number, exact inverter brand and model, system output projection (kWh/month), all warranty periods stated separately, TNB Solar ATAP application handling, and total turnkey price including all installation, permits, and commissioning costs.
Step 4: Compare at Least Three Quotes
Get quotes from at least three different solar companies in Malaysia before deciding. Price alone should not be the deciding factor — a system that underperforms by 15% for 25 years costs more in lost savings than the initial price difference between premium and budget installers.
Step 5: Check Tier 1 Panel and Inverter Brands
Insist on Bloomberg Tier 1 panels: LONGi, Jinko Solar, JA Solar, Risen, or Canadian Solar. For inverters, leading options include Huawei FusionSolar, Sungrow, and Solis. Avoid unbranded or Tier 3 components, regardless of how low the quote is.
Government Incentives for Solar in Malaysia 2026
Solar ATAP — Export Credits Programme
Solar ATAP (Solar Accelerated Transition Action Programme) allows homeowners to export excess solar energy to the TNB grid and earn bill credits at the TNB Energy Charge rate (RM 0.2703/kWh for domestic, or RM 0.3703/kWh above 1,500 kWh a month). Capacity is set by the Government and allocated first-come, first-served, and contracts run for up to 10 years. Unused export credit is forfeited at the end of each billing period, so self-consumption matters most. Your solar panel company in Malaysia must manage the SEDA application and TNB meter commissioning.
Solar ATAP Export Credits
Solar ATAP credits homeowners at the Energy Charge, RM 0.2703/kWh, for every unit of excess solar electricity exported to the TNB grid, while each kWh used at home avoids RM 0.4443/kWh. This creates a dual return: reduce your TNB bill through self-consumption plus earn export credits. Use the Trexon calculator to see your projected monthly Solar ATAP savings before installation.
GITA (Green Investment Tax Allowance)
The GITA Asset covers qualifying solar PV capex verified by MGTC and listed under MyHIJAU: a 60% allowance (Tier 2) on qualifying capital expenditure, set off against up to 70% of statutory income. At the 24% corporate tax rate the allowance is worth up to 14.4% of the qualifying cost once fully used. Subject to MGTC verification. Systems must be commissioned and GITA applications submitted to MGTC by 31 December 2026 — see our GITA 2026 guide for details.
EPF (KWSP): Not Allowed for Solar
Solar panels are not on KWSP's withdrawal list, so EPF Account 2 cannot be used, and Trexon does not offer EPF-funded solar. Use a bank loan or a 0% credit-card instalment plan of up to 24 months instead. See our financing guide for the financing options available through Trexon.
Red Flags to Watch Out For
Before signing with any solar company in Malaysia, watch for these warning signs:
- No SEDA registration number: If they cannot provide it immediately, walk away.
- Prices below about RM 2.00/Wp for residential: Can indicate Tier 3 panels, grey-market inverters, or underqualified installers. Ask exactly which panel and inverter models are quoted.
- No physical office address: A solar company with only a WhatsApp number cannot honour a 25-year relationship.
- Vague warranty terms: "25-year warranty" can mask short workmanship cover. Ask for each warranty period in writing, separately.
- No monitoring system included: Any reputable solar panel company in Malaysia includes a monitoring app. Without it, you cannot verify your system's output from day one.
- High-pressure tactics or artificial deadlines: A legitimate solar company does not need to rush you.
