Configure solarYour Solar Panels May Also Qualify for I-RECs
Every kilowatt-hour your solar panels generate offsets CO2 and creates a tradeable certificate. Malaysian solar owners may be able to sell I-REC certificates through a third-party aggregator. Prices are set by that market, are not guaranteed, and are not a Trexon service.
Key Takeaways
- Every solar MWh generated can be registered as 1 I-REC certificate. Its price is set by the third-party market and varies.
- A 6kWp home system offsets roughly 5.6 tonnes of CO2/year; any I-REC income depends on an aggregator and market prices and is not guaranteed.
- Commercial solar can support ESG Scope 2 emission reduction reporting; any certificate income depends on the third-party market and is not guaranteed.
- Residential owners need an aggregator (pooling with others). Commercial/industrial can register directly with I-REC.
- The Peninsular Malaysia grid emission factor is 0.740 tCO2/MWh (Suruhanjaya Tenaga, 2024 (provisional)).
- Carbon credit income from solar is in addition to — not instead of — your electricity bill savings and Solar ATAP credits.

Carbon Credits vs RECs: What's the Difference?
Many solar panel owners are confused about the difference between carbon credits and Renewable Energy Certificates (RECs). Both represent the environmental value of clean energy generation — but they work differently, have different buyers, and generate different income streams.
| Feature | Carbon Credits | RECs (I-REC) |
|---|---|---|
| What it represents | 1 tonne of CO2 avoided/removed | 1 MWh of renewable electricity |
| Standard/Platform | Verra VCS, Gold Standard, ACM | I-REC, TIGR, RECerT |
| Who buys | Companies offsetting emissions | Companies claiming RE usage (Scope 2) |
| Verification | Rigorous 3rd-party audit required | Metered generation data sufficient |
| Accessible for homeowners | Difficult — high verification cost | Yes — via aggregator |
| Accessible for businesses | Yes — with methodology | Yes — direct I-REC registration |
| Current Malaysia pricing | Varies by project and market | Varies by market |
| Payment frequency | Annual (post-verification) | Quarterly |
For most Malaysian solar panel owners, I-RECs are the practical choice. Carbon credits (Verra VCS, Gold Standard) require expensive third-party audits — only feasible for large projects. I-RECs use your existing TNB meter data, making them accessible to any SEDA-registered system.
Bursa Carbon Exchange (BCX): Malaysia's Carbon Trading Platform
Launched in December 2022 by Bursa Malaysia, the Bursa Carbon Exchange (BCX) is Southeast Asia's first end-to-end voluntary carbon exchange. It connects renewable energy generators — including solar panel owners — with companies that need to offset their greenhouse gas emissions.
You Generate Clean Energy
Your solar panels produce electricity, displacing coal/gas generation from the national grid.
I-REC Certificates Issued
Your metered generation data is converted to I-REC certificates — 1 certificate per MWh generated.
Listed on BCX
Your I-RECs are listed on Bursa Carbon Exchange, where Malaysian and international buyers can purchase them.
Corporations Buy Credits
Companies with ESG commitments, Scope 2 targets, or net-zero pledges purchase your RECs to prove clean energy use.
You Receive Payment
Payment terms and amounts are set by the aggregator or buyer and are not guaranteed.
Credits Retired
Once purchased, RECs are 'retired' in the registry — preventing double-counting and ensuring integrity.
Illustrative Price Scenarios (not a quote)
Illustrative only, not Trexon prices or a market quote. Prices depend on demand from companies buying RECs for ESG reporting and on supply; they can rise or fall. Compare aggregator terms before you register.
Who Buys Carbon Credits in Malaysia?
I-REC Standard: International Renewable Energy Certificates
The I-REC Standard is the international framework for issuing Renewable Energy Certificates. In Malaysia, I-RECs are the primary mechanism for solar panel owners to monetize the environmental value of their clean energy generation. Each I-REC represents 1 MWh of verified renewable electricity.
Malaysia Grid Emission Factor: Why It Matters
Peninsular Malaysia's grid emission factor of 0.740 tCO2/MWh is significantly higher than Singapore (0.41) or the EU average (0.26). This means each MWh of solar generated in Malaysia offsets nearly 3x more CO2 than in Europe.

Estimates based on 1,260 kWh/kWp/year (Trexon yield basis), 0.740 tCO2/MWh grid emission factor (Suruhanjaya Tenaga, 2024 (provisional)). Actual income varies based on system performance, aggregator fees, and market pricing. Not financial advice.
Homeowner Guide: 6-10kWp Systems
If you have a residential solar system between 6-10kWp, you can participate in carbon credit markets through aggregator services. Here's what you need to know about realistic income expectations, the aggregator process, and which services operate in Malaysia.
| System | Generation/Year | CO2 Offset | REC Income |
|---|---|---|---|
| 6kWp (Terrace House) | ~7,560 kWh/year | 5.6 tonnes/year | Depends on the current I-REC price |
| 8kWp (Semi-D) | ~10,080 kWh/year | 7.5 tonnes/year | Depends on the current I-REC price |
| 10kWp (Bungalow) | ~12,600 kWh/year | 9.3 tonnes/year | Depends on the current I-REC price |
How Aggregators Work for Homeowners
Sign up with an approved aggregator who registers your SEDA-registered system into their pooled portfolio.
Your generation data flows automatically from TNB smart meter or your inverter monitoring portal. No manual input needed.
Quarterly payments arrive in your account after the aggregator sells the pooled I-RECs. Payout depends on the aggregator and market prices and is not guaranteed.
Business & ESG Guide: Commercial & Industrial Solar
For businesses with 50kWp+ solar installations, carbon credits and I-RECs offer both a revenue stream and powerful ESG reporting tools. As Bursa Malaysia strengthens mandatory ESG disclosure requirements for listed companies, solar-generated RECs are becoming a strategic asset.
Scope 2 Emission Reduction
I-RECs allow you to claim market-based Scope 2 emissions as zero — critical for GHG reporting under GRI, CDP, and Bursa ESG framework.
Bursa ESG Compliance
From 2025, all Bursa-listed companies must disclose climate-related risks. Solar RECs provide quantifiable, auditable evidence of RE commitment.
EU CBAM Readiness
Malaysia's export manufacturers face EU Carbon Border Adjustment Mechanism from 2026. RECs reduce your embedded carbon footprint, protecting export competitiveness.
Green Financing Access
Some banks may consider lower interest rates on green loans and sustainability-linked financing when you can demonstrate RE usage through I-RECs.
Supply Chain Compliance
MNCs increasingly require Scope 3 supplier emissions data. Showing solar REC certification keeps you in their approved vendor list.
Net-Zero Credibility
I-RECs from your own solar installation can support your net-zero reporting; check what your reporting framework accepts.

6-Step I-REC Registration Process
Registering your solar system for I-REC issuance requires coordination between your SEDA registration, TNB metering data, and the I-REC Local Issuer. Here is the complete step-by-step process for Malaysian solar owners.
Confirm SEDA Registration
Already done for existing systemsEnsure your solar system is fully registered under SEDA's Solar ATAP programme and connected to the TNB grid. You'll need your SEDA application number and connection approval letter.
Gather System Documentation
1-2 weeksCompile: SEDA registration certificate, TNB connection agreement, single-line diagram, inverter specifications, metering point ID (MPAN), and 12 months of generation data from your monitoring system.
Select Path: Aggregator or Direct
1 day decisionSystems under 100kWp: contact an approved aggregator. Systems 100kWp+: apply directly to APX (the I-REC Local Issuer for Malaysia) at www.apx.com. Aggregator handles all paperwork for residential.
Submit I-REC Application
2-4 weeks processingYour aggregator (or you directly) submits the Device Registration Form to APX, including all system documentation, GPS coordinates, TNB connection point details, and metering configuration.
Metering Verification
4-6 weeksAPX or their auditor verifies your metering data matches actual generation. For residential systems going through aggregators, this is handled automatically via smart meter data from TNB.
First I-RECs Issued
Quarterly thereafterOnce registered, I-RECs are issued quarterly based on your metered generation. Your aggregator sells them on the market and transfers payment minus their service fee (typically 15-30% of REC income).
5-Year Carbon Credit Revenue Projection
Certificate prices can rise or fall, and returns are not guaranteed. The projection below is an illustration only (+8%/year), not a forecast: it shows how annual I-REC income could grow over 5 years for different system sizes.
Projected I-REC Income — 10kWp System
5-Year Cumulative Income: RM1,848 for a 10kWp system — entirely on top of your electricity savings. Adjust the system size slider above to recalculate.
Aggregator vs Direct Registration: Which Applies to You?
The right path to market depends on your system size and whether you can meet the minimum trading thresholds on Bursa Carbon Exchange. Generally, systems below 100kWp benefit from aggregation, while larger commercial and industrial systems can trade directly.
