"Install solar with 0% interest and zero upfront!" — You've seen the ads. But is 0% interest solar financing in Malaysia real, or is it clever marketing? Here is what is genuinely available in 2026 and what to check before you sign.
The 3 Types of "0% Interest" Solar Financing
1. Credit Card 0% Instalment Plans
How it works: Pay for solar with your credit card at the installer's checkout, then split it into a 0% instalment plan. At Trexon's checkout the plans run up to 24 months:
| Bank | 0% Tenure |
|---|---|
| Affin, AmBank, HSBC, RHB, Standard Chartered | 3, 6, 12 or 24 months |
| Alliance, OCBC, UOB | 6, 12 or 24 months |
Example:
- Solar system cost: RM 20,999 (7.44 kWp, Solis inverter)
- Home with a RM 500 monthly TNB bill
- 24-month 0% plan
- Monthly instalment: RM 875 (zero interest)
- Estimated electricity savings: about RM 292/month
- Net cost: about RM 583/month for 24 months, then the full saving is yours
Is this truly 0% interest? Yes, on the plan itself. However:
- You pay the full price (no discount for paying in instalments)
- Your credit card limit must cover the purchase
- Missing a payment can trigger card interest and charges on the remaining balance
Who it's for:
- Homeowners with a high enough credit card limit
- Those who want to preserve cash for other uses
- Buyers who can afford the higher monthly instalment for up to 24 months
2. Promotional Bank Rates
How it works: Banks sometimes run limited-time campaigns with lower rates on green or solar financing. Terms, quotas and eligibility are set by each bank and change often.
What to check:
- How long the promotional rate lasts and what it reverts to
- Whether the rate is fixed or floating
- The total amount payable over the full tenure
Maybank Solar PV Financing, for example, lends up to RM 100,000 over up to 10 years at a floating rate (Maybank's own illustration: SBR + 2.70%). Check the current rate on the bank's own product page before you apply.
3. Power Purchase Agreement (PPA) — Third-Party-Owned, No System Purchase
How it works: A third-party investor installs and owns the solar system on your roof. You buy the solar electricity from them at a rate they set, so compare it with your TNB tariff. There is no interest because you are not borrowing — and you do not own the system.
PPAs are mainly for commercial and industrial sites. Trexon does not offer a PPA; our routes are outright purchase, 0% card instalments, bank loans, OKAPI rent-to-own for homes and a Mitsubishi HC Capital finance lease for businesses. Every route starts with a booking: RM2,000 for homes, or 20% of the system price (capped at RM20,000) for commercial projects.
The "Zero Deposit, Pay Later" Schemes — How They Work and the Real Cost
How it works: You install the system without paying a deposit, and payments are deferred for a set period. The cost depends on the financing behind the offer. Some installers advertise:
"No deposit! No payment for 6 months! 0% interest!"
What to check:
- Who the lender is (a bank, or a finance company under a hire-purchase agreement)
- Whether "0%" covers the whole tenure or only a deferment period
- The rate that applies after any deferment
- Early settlement charges
Is this a scam? Not necessarily, but it can be misleading if the "0%" refers only to a grace period. Ask for the total amount payable in writing.
How to Identify Genuine 0% Financing vs Marketing Tricks
Red Flags (Fake "0% Interest")
- "0% interest BUT higher total price" — If the cash price is lower than the "0% financing" price, the difference is a hidden cost
- "0% for first year only" — Check the rate after the promotional period
- "No interest, just service fees" — Service fees can be interest by another name
- "Free solar, just pay per kWh" — That's a PPA, not ownership. You're buying electricity, not the system
Green Flags (Genuine 0% Financing)
- Card instalment plan run by your bank — The plan terms come from the card issuer
- Written agreement stating the rate — Documented by a licensed bank
- Same cash price = 0% financing price — No markup for choosing instalments
- Bank Negara-regulated products — Check the bank's official website, not just the installer's flyer
Comparing Total Costs: 0% Instalments vs Bank Loan vs Cash
Let's compare a RM 20,999 solar system (7.44 kWp) for a home with a RM 500 monthly bill:
| Payment Method | Upfront Cost | Monthly Payment | Total Paid | Estimated 25-Year Savings |
|---|---|---|---|---|
| Cash Purchase | RM 20,999 | RM 0 | RM 20,999 | about RM 69,600* |
| 0% Card Instalment (24 months) | RM 2,000 booking | RM 875 (2 yrs) | RM 20,999 | about RM 69,600* |
| Bank Loan | RM 2,000 booking | Depends on the bank's rate and tenure | RM 20,999 plus interest | about RM 69,600* less interest |
*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 (export credit counted for the 10-year Solar ATAP term only); no tariff increases. Your bill and roof will change the figures.
Verdict: A 0% card instalment costs the same as paying cash, as long as you pay on time. A bank loan adds interest but spreads payments over a longer tenure.
Should You Wait for a Promotion or Buy Now?
Waiting costs you savings. Here's why:
Scenario A: Wait 6 Months for a Campaign
- Delay: 6 months
- Lost electricity savings: about RM 292/month x 6 = about RM 1,752
- Interest saved: depends on the campaign rate, which is not known in advance
- Net benefit: uncertain
Scenario B: Buy Now
- Delay: 0 months
- Start saving immediately: about RM 292/month
- Pay with a 0% card instalment, cash or a bank loan at today's rate
- Savings start from your first bill after commissioning
Conclusion: Unless a promotion is confirmed and its terms are in writing, the estimated savings you give up by waiting (about RM 1,752 in this example) are likely to outweigh the interest you might save.
Solar ATAP Export Credits: Maximise Your Savings
Malaysia's Solar ATAP programme lets you export excess solar energy to TNB and earn bill credits at the Energy Charge rate (RM 0.2703/kWh for homes, or RM 0.3703/kWh above 1,500 kWh a month). Unused credit is forfeited at the end of each billing period.
Example:
- 7.44 kWp system: RM 20,999
- Home with a RM 500 monthly bill
- Monthly savings (self-consumption + export credits): about RM 292
- Simple payback: about 6.0 years before any financing cost
Solar ATAP export credits combined with self-consumption savings are what pay the system back. Size the system to your own use, because extra credit is forfeited.

How to Get a Good Solar Financing Deal in 2026
Step 1: Check Current Bank Terms
Check each bank's own solar or green financing page for current rates and campaigns. Promotions, when they run, are announced by the banks:
- Check the rate and how long it lasts
- Check the tenure and total amount payable
- Check eligibility and quotas
Step 2: Compare 0% Instalments vs a Bank Loan
If no promotion is available:
- Credit card limit covers the system: Use a 0% instalment plan (up to 24 months)
- Credit card limit too low, or you want a lower monthly payment: A bank loan with a longer tenure
Step 3: Check the Installer's Offer
Ask for:
- An itemised quote with the same price for cash and 0% instalments
- Written warranty terms (panel, inverter and workmanship)
- Optional maintenance package available (cleaning + monitoring)
FAQ: 0% Interest Solar Financing Malaysia
Is 0% interest solar financing real in Malaysia?
Yes, through credit card instalment plans. At Trexon's checkout, 0% plans run up to 24 months with Affin, AmBank, HSBC, RHB, Standard Chartered, Alliance, OCBC and UOB cards. "0% interest" PPA schemes are not ownership — you buy the electricity, not the system.
What's the catch with 0% solar financing?
For card instalments: no catch if you pay on time, but a missed payment can trigger card interest and charges. For a PPA: you never own the system, and the electricity rate is set by the owner.
Do I need money down to get solar in Malaysia?
Every Trexon route starts with a booking (RM2,000 for homes, or 20% of the system price capped at RM20,000 for commercial projects), credited in full to the system price. After that you can use: (1) 0% card instalments of up to 24 months, (2) a bank loan, (3) OKAPI rent-to-own for homes, or (4) a finance lease for businesses. Each lender sets its own eligibility rules.
Which is better: 0% instalments or a bank loan?
A 0% instalment if your credit limit and monthly budget allow it, because you pay no interest. A bank loan offers a longer tenure (Maybank Solar PV Financing: up to 10 years), so the monthly payment is lower, but you pay interest.
Should I wait for a 0% promotion or buy solar now?
On our estimate, a home with a RM500 bill and a 7.44 kWp system gives up about RM1,752 in savings by waiting 6 months. Unless a promotion is confirmed in writing, buying now is usually the better choice.
Conclusion: 0% Financing Exists, But Don't Let It Delay Your Decision
Genuine 0% interest solar financing is available in Malaysia through:
- Credit card instalment plans — up to 24 months at Trexon's checkout
- Bank promotions — when banks run them; check the bank's current terms
Don't let "waiting for 0%" delay your solar installation. Compare the monthly payment with your estimated saving and choose the route you can comfortably pay.
A simple financing strategy:
- Use a 0% card instalment if you have sufficient credit limit and monthly budget
- Otherwise, compare bank loans and check each bank's current rate
