Solar PPA Rates in Malaysia: Compare the Contract Terms
Decision details
Fits if: Commercial premises owners or managers comparing a PPA with purchasing a system.
Main drawback: This page establishes no standard PPA market rate, savings, payback or ownership outcome.
Compare: all payments, escalation, export rate, ownership/transfer, service, roof risk, term, default and termination.
In this guide
What should a PPA rate offer disclose?
For a first decision, do not start with the headline discount. Compare net costs over the same period: for a PPA, contracted energy charges, utility bills that remain and export credits; for an owned system, cash price or total financing cost, the post-solar utility bill and export credits. Add service, replacement and exit costs not covered under each path. A PPA may reduce upfront system capital, but the asset owner, term, service scope and termination payment determine the actual obligation.
Ask the agreement to state the energy rate, when it changes, escalation, fees or deposits, billing period, exclusions, metering method, who receives export credits and which TNB charges remain. If it uses multiple rates, request an example calculation for a stated month and load profile, not just a marketing figure.
Compare a PPA with a purchase on equal terms
Use actual bills, interval usage, tariff class, voltage, maximum demand where relevant, operating hours and roof conditions. For each option, record all payments over the same period, service, replacements, exports, asset ownership and transfer value. Include tax allowances or credits only after an adviser confirms eligibility.
A PPA does not by itself guarantee no upfront payment, savings or a particular maintenance scope. The contract may include fees, minimum payments, escalation or customer responsibilities. Obtain every condition before comparing.
Exit terms and the site
Ask what happens if the premises are sold, the tenant changes, the business closes, the roof is damaged, a party defaults or the contract ends early. Identify who may transfer or buy the asset, how its price is calculated, who pays removal and roof reinstatement, and whether building-owner consent is needed.
For a non-domestic installation, ask the applicant to state the declared inverter capacity in kWac and how it is assessed against site maximum demand under the applicable terms [source] [source]. Verify any scheme or contract term against the applicant-specific documents [source].
One provider’s published rate-card example
To make the comparison concrete, this table cites rates on Trexon’s PPA page as read on 30 September 2026. These are one provider’s published figures, not a market rate, a site quote or measured savings. Trexon’s promotional headline says 10–20% below TNB tariffs, while its segment examples differ; ask the provider to explain the tariff comparator and calculation for your premises [source] [source].
| Segment on rate card | Displayed system band | Displayed PPA rate | Reference tariff Trexon displays |
|---|---|---|---|
| SME Office | 50–100 kWp | RM0.36/kWh | RM0.435/kWh |
| Warehouse / Logistics | 100–300 kWp | RM0.34/kWh | RM0.435/kWh |
| Factory / Industrial | 300–1,000 kWp | RM0.28/kWh | E2 HV RM0.337/kWh |
| Shopping Mall | 500–2,000 kWp | RM0.30/kWh | RM0.435/kWh |
Each row is an example for the provider’s named segment; do not mix the factory E2 HV reference with other segment tariffs. The same Trexon page describes a 15–25 year term, RM0 upfront capital, a fixed rate or 1–3% annual escalator, and end-of-term options. It says the provider bears maintenance, but actual exclusions, roof work, minimum payments, security and termination formula must be checked in the contract draft [source].
| Term | What Trexon states on its page | Buyer check |
|---|---|---|
| Term | 15–25 years; building lease should match | Start/end dates, property transfer and building-owner rights |
| Upfront payment | RM0 upfront capital as advertised | Deposit, security, application/connection fees and excluded customer costs |
| Rate | Fixed for the term or annual escalator of 1–3% | Rate formula, minimum energy bill, taxes and TNB charges that remain |
| Maintenance and end of term | Trexon says the provider bears maintenance; end options include renewal, purchase or removal | Work scope, exclusions, buyout value, removal and roof reinstatement in the contract |
Frequently asked questions
What does a solar PPA mean?
A PPA is an energy purchase agreement. The actual contract must identify who installs, owns, maintains and sells the energy, and who pays each fee; the label alone does not set the terms.
Does a solar PPA have no upfront payment?
Do not assume so. Check deposits, application or connection fees, security, minimum payments and other responsibilities in the offer.
How should I compare a PPA rate with my site's tariff?
Request the written calculation method: billed solar energy, time-based rates, escalation, TNB charges that remain, export credits and expected self-consumed kWh. Match it to the site's tariff and interval records; no single rate guarantees savings at every site.
Who owns the system at the end of the contract?
Check ownership during the term, transfer options and formula, residual value, removal and roof reinstatement costs. Do not assume ownership transfers automatically.
Is a PPA always more or less expensive than buying?
There is no universal result. Compare total PPA payments over the same period with ownership, financing, service, exports, verified tax treatment and asset value, using the same site and energy assumptions.
Can one provider's rate card set the market rate?
No. Trexon's dated page is one provider's advertised example, and its headline discount range differs from some segment examples. Request a current written quote with the exact tariff comparator, all fees, and the same load and period as your purchase alternative.
