Solar PPA vs Outright Purchase for Factories in Malaysia

Industrial Solar

Official sources reviewed: 15 October 2026. This guide discusses on-site factory rooftop solar in Peninsular Malaysia. It does not compare off-site corporate electricity procurement arrangements.

With outright purchase, the factory buys and owns the solar system. Under the PPA model described by SEDA, a registered investor owns the system and the site owner pays for solar electricity in RM/kWh. The decision involves capital allocation, contractual obligations and control of the asset. Neither arrangement is automatically the better choice for every factory.

For a useful comparison, start with the same facility, electricity demand and proposed technical scope. Then compare what the factory pays, what it receives and which responsibilities it retains under each offer.

How does a solar PPA differ from outright purchase?

Decision Outright purchase On-site solar PPA
System ownership The buyer owns the system. In SEDA’s described model, the registered investor owns it.
Payment basis The system purchase price, plus financing costs if financed. Solar electricity charged in RM/kWh under the agreement.
Capital planning Compare the purchase and any associated project work with other uses of capital. Check the precise scope of any zero-upfront-capex offer and remaining site costs.
System care Define maintenance, warranties and corrective work in the purchase and service scope. Check the investor’s maintenance obligations and remedies in the agreement.
Future changes Consider how upgrades, roof repairs or relocation affect the owned asset. Review consent, transfer, termination and end-of-term provisions.

The ownership and payment distinctions are supported by SEDA’s Solar ATAP modes of purchase and PPA and leasing guidance. The planning questions in the table are considerations for reviewing individual offers, not standard terms imposed on every contract.

Is a solar PPA the same as leasing?

SEDA describes them separately. Its PPA model uses energy-based payments and investor ownership. Its leasing model uses fixed monthly payments, with ownership passing to the site owner after the lease period.

When reviewing an offer, ask whether it is a PPA, lease, financed purchase or hybrid. Confirm the payment basis and ownership provisions in the actual documents rather than relying on a sales label. This is particularly useful when comparing proposals that use similar phrases but allocate responsibilities differently.

Does zero upfront cost mean the factory has no costs or risks?

No. SEDA describes zero-upfront-capex models offered by registered solar PV investors, but the complete offer still needs review. The phrase alone does not establish which site works, fees or future obligations are included.

Ask the provider to identify any customer-funded roof repairs, structural work, electrical changes, access facilities, insurance requirements and other charges. Request a written list of exclusions before comparing the offer with a purchase quotation.

Also review the electricity payment obligation. Does it relate to generation, delivery, consumption or another defined quantity? How is it metered? Are there minimum payments, adjustments or obligations when the factory cannot take electricity? These are contract questions; this guide does not assume that any particular clause is present.

How should a factory compare the financial outcome?

Compare the factory’s cash flows over the same evaluation period. Use the same demand records, generation assumptions, tariff basis and operating calendar wherever the technical designs allow a fair comparison.

For a purchase, identify the initial investment, any financing payments, ongoing service costs and replacement assumptions. For a PPA, identify all customer payments, possible price changes and costs outside the provider’s scope. In both cases, include the remaining grid bill and explain how any eligible export credits are allocated.

Ask the finance team to review net present value and downside scenarios as well as annual savings. Show tax assumptions separately and confirm their treatment for the proposed ownership arrangement. Do not apply a system-owner payback figure to a customer that is buying electricity without owning the asset.

Our industrial solar costs and payback guide explains the underlying savings model. The purpose here is to compare the customer’s ownership and payment choices, not repeat a generic payback estimate.

What happens during weekends and production shutdowns?

Give the project team the factory’s operating calendar, including maintenance outages, holidays and periods of reduced demand. Ask each provider to model these periods explicitly.

For a PPA, establish how the agreement treats electricity during low-demand periods and planned or unplanned interruptions. For a purchased system, examine the effect on on-site use, any permitted exports and any output curtailed by the design. Ask who controls operational changes and who needs notice before the factory shuts down.

Keep financing separate from the connection route. A PPA is not itself permission to export electricity. Read Solar ATAP vs SELCO for factories and confirm the applicable programme and approval requirements for the site.

Who handles maintenance, roof repairs and equipment faults?

Ask the offer to name the party responsible for monitoring, inspection, fault investigation, replacement parts and warranty coordination. Confirm response commitments, reporting and any exclusions in writing.

Under either arrangement, discuss roof access and how repairs would be coordinated. If panels must be temporarily removed, who authorises the work, carries the cost and arranges reinstatement? For a PPA, also ask how an outage caused by roof work affects payment obligations.

Equipment warranty, maintenance scope and contractual performance remedies are different parts of the review. Define each rather than assuming one includes the others. Candela’s monitoring and maintenance service page explains questions to consider when agreeing system care.

What if the factory relocates or the tenancy ends?

For a leased factory, compare the remaining tenancy with the proposed solar agreement and confirm the building owner’s permission. Identify who controls roof rights, who holds the electricity account and who is authorised to approve alterations.

For a PPA, ask what happens on relocation, a building sale, business closure or early termination. Review any transfer conditions, buyout calculation and removal responsibilities. Do not assume that a contract transfers automatically to a new occupier or that the equipment becomes yours at the end of a PPA.

For a purchased system, include potential removal, reinstatement and relocation work in the planning discussion. The factory roof suitability guide covers roof records, access and building-condition questions to address first.

Questions to ask before choosing a provider

Use the answers to compare documented proposals. A low starting rate or a short headline payback should not replace a review of the complete obligations.

Start with the factory’s technical requirements

Share the facility location, electricity bills, interval demand data where available, operating schedule and roof information. Include ownership or tenancy details and any planned changes to production.
