How to Choose a Solar Installer
in Malaysia: RPVSP Check & Scam Red Flags

Regulatory details below are drawn directly from SEDA and Suruhanjaya Tenaga's own published pages, checked in September 2026 — not from a marketplace listing or a reseller's marketing claim. Two claims we checked and could not confirm on any regulator source are deliberately left off this page rather than guessed at: see the sources section below. Ask us on WhatsApp.

What SEDA's RPVSP registration is, and why it matters

Hiring a solar installer in Malaysia is not like hiring a painter or a handyman — there is a real, regulator-run registration scheme behind it, and it is tied directly to the one step almost every homeowner actually takes: applying for Net Energy Metering (NEM) so exported solar power offsets the TNB bill.

SEDA’s own official Net Energy Metering (NEM) FAQ states directly: ‘NEM applicant shall appoint SEDA’s Registered PV Service Provider (RPVSP) for NEM application submission.’ Because virtually all grid-tied residential solar installations in Malaysia go through the NEM scheme, this makes RPVSP registration a de facto mandatory requirement for the installer hired for a standard grid-tied home solar system — and it is independently checkable by the homeowner via SEDA’s public directory before signing anything.

The installer-registration scheme run by the Sustainable Energy Development Authority (SEDA) for solar PV installers/system integrators is called the ‘Registered PV Service Provider’ scheme (RPVSP), confirmed via SEDA’s own live directory page, its own online application portal, and its own renewal notices. RPVSP must not be confused with ‘RPVI’ (Registered Solar PV Investor) — a separate SEDA scheme for entities offering third-party solar financing/investment arrangements, not for installers or system integrators. RPVSP registration is renewed annually, and both new and renewing applicants must attend a SEDA interview session as part of the process, per SEDA’s own RPVSP renewal-and-new-registration notice for the 2021 cycle. That interview-session detail comes from a 2021-dated notice, so the exact current-cycle requirement should ideally be re-confirmed against SEDA’s latest renewal notice before being stated as a fixed, unchanging annual rule — though the RPVSP directory itself, and the scheme’s existence, are confirmed live and current.

Per SEDA’s own NEM FAQ, the NEM meter itself is supplied and installed by the Distribution Licensee — Tenaga Nasional Berhad (TNB) — not by the homeowner’s chosen solar installer. The installer’s scope of work ends at the interconnection point with TNB’s network. The homeowner, as the registered NEM Consumer, remains responsible for the safe operation and maintenance of the solar PV installation up to that interconnection point.

Per SEDA’s NEM FAQ (direct quote), an ST generation licence is triggered for systems ‘above 24kW for single phase; and above 72kW for three phase’. This is a SYSTEM-SIZE threshold under the NOVA (large-scale)/generation-licence track, not a licence an installer personally holds to operate as a business. The overwhelming majority of residential rooftop solar systems, typically 4-12kWp, sit well under this threshold and never trigger it.

How to check the RPVSP directory before you sign

SEDA publishes a publicly searchable RPVSP directory at services.seda.gov.my/spqp/listing. A homeowner can look up any installer’s name there before signing a contract or paying a deposit, to confirm the company is currently a registered PV Service Provider.

In practice: before you pay a deposit or sign a contract, open the directory yourself and search the exact company name on the quote — not a similar-sounding brand, not a sales agent's own name. Take a screenshot with the date visible and keep it with your other paperwork. If the company is not listed, ask them directly why, and treat a vague answer as a reason to get a second quote from a company that is listed.

SEDA's own scam red flags and verification checklist

SEDA has published its own consumer alert warning of unauthorised individuals/companies soliciting payment from homeowners and issuing fake NEM certificates. The red flags SEDA itself names are: overpromising unrealistically high returns, guaranteeing a solar PV quota from SEDA, falsely claiming the system needs zero maintenance, and specifically targeting people unfamiliar with solar investment. SEDA’s own recommended checks are: verify the NEM certificate at SEDA’s own checker (services.seda.gov.my/nem/cert/checker); confirm the company appears in the RPVSP directory; ask for the draft contract, since a NEM contract should only be signed with a registered provider; compare quotes on component quality, warranty terms, installation duration and expected generation output rather than on price alone; do not release final payment until satisfied the work is complete; and keep all contracts, receipts, photographs and correspondence.

Two of SEDA's own checks above are worth repeating on their own: the NEM certificate checker (services.seda.gov.my/nem/cert/checker) verifies a specific installation's certificate after the work is done, while the RPVSP directory above verifies a company's registration before you hire them. They are different tools for different moments — use both, not just one.

Electrical registration: what's confirmed, and what's a reasonable inference

An installer's technicians do more than bolt panels to a roof — they connect a solar inverter and distribution board into your home's mains wiring, which is genuinely electrical work. Here is exactly what is confirmed about Malaysia's electrical-trade registration framework, and where this page is honest about drawing an inference rather than citing a solar-specific rule:

ST’s own contractor-registration page confirms it oversees electrical-contractor registration ‘by category in accordance with the Electricity Regulations 1994’ through its ECOS system, and ST’s ECOS category list (‘Jenis Kontraktor’) names five contractor categories, including ‘Kontraktor Elektrik’ (‘Electrical Contractor’), defined as covering electrical work, installation and electrical wiring. Separately, wireman registration under Regulation 50 of the Electricity Regulations 1994 requires the applicant to be a Malaysian citizen, at least 18 years old, to have completed at least Form Five, to have two years’ experience working under a registered Electrical Contractor, to be competent in Bahasa Malaysia, and to have knowledge of wiring, first aid, and the Electricity Supply Act 1990. Both of these are verified, general facts about Malaysia’s electrical-trade registration framework. Whether this framework specifically governs the mains-side DB/inverter connection work performed during a solar installation is NOT separately confirmed by any solar-specific ST circular — none was found stating this in so many words. What can honestly be said beyond that is an INFERENCE, not a regulatory citation: connecting a solar inverter/DB to the household mains is electrical work in the ordinary sense, and the same Electricity Regulations 1994 framework that already governs every other electrical trade would reasonably be expected to apply to that connection work too. A page should present this as ‘this general framework likely applies to the mains-side connection work’ — never as ‘ST requires solar installers to be registered electrical contractors/wiremen’, which overstates a general framework as a solar-specific rule that no regulator source was found to state.

One concrete, checkable question follows directly from this: SEDA runs an official ‘Grid-Connected Photovoltaic (GCPV) System Course for Wireman & Chargeman’ — a real, SEDA-run training course a homeowner can ask an installer’s technical staff whether their wireman/chargeman has completed. Asking this is a fair, specific vetting question even where a solar-specific licensing statement does not exist.

Questions to ask before you sign

This checklist is built only from the verified facts above — nothing here introduces a new regulatory claim, it simply turns the facts already stated into questions you can ask, and answers you can independently check:

• Is this exact company name listed as a currently registered RPVSP in SEDA's public directory? Check it yourself — do not take the installer's word for it.
• Will they be submitting the NEM application under their own RPVSP registration, as SEDA's NEM FAQ requires?
• Has their wireman or chargeman completed SEDA's Grid-Connected Photovoltaic (GCPV) course for Wireman & Chargeman?
• Does the company or its technicians hold Suruhanjaya Tenaga electrical-contractor or wireman registration for the DB and inverter connection work?
• Do they confirm, in writing, that their scope ends at the interconnection point, and that TNB — not the installer — supplies and installs the NEM meter itself?
• If your proposed system is at or near 24kW (single phase) or 72kW (three phase), have they explained whether a Suruhanjaya Tenaga generation licence applies? (For the great majority of home-sized systems, well under these thresholds, this simply will not come up.)
• After installation, will you be shown how to verify your own NEM certificate at SEDA's certificate checker, rather than relying on the installer's paperwork alone?
• Is there a full written contract and an itemised quote, covering component quality, warranty terms, installation duration and expected generation output — not just a headline price?
• Does the payment schedule let you withhold final payment until you are satisfied the work is complete?

Where to complain if something goes wrong

General consumer complaints in Malaysia go to the Ministry of Domestic Trade and Cost of Living (KPDNHEP), via e-aduan.kpdnhep.gov.my or by email to e-aduan@kpdnhep.gov.my. If a dispute is not resolved, a consumer claim under the Consumer Protection Act 1999 can be escalated to the Tribunal for Consumer Claims Malaysia (Tribunal Tuntutan Pengguna Malaysia, TTPM), which hears claims up to RM25,000 and can be filed online at ttpm.kpdnhep.gov.my or in person.

Keep every contract, receipt, photograph and message with the installer from day one — SEDA's own guidance above recommends exactly this, and it is also what KPDNHEP and the Tribunal will ask for if a complaint is ever escalated.

What about cost and system size?

This page deliberately does not quote a single ringgit figure — it is about vetting who you hire, not what the job costs. For system pricing by size (kWp), how NEM's one-to-one offset works, typical payback periods, and roof-suitability questions, see our separate home solar panel cost & NEM guide, which covers that ground in full.

Where these facts come from

Every regulatory and consumer-protection statement on this page is drawn directly from SEDA's own NEM FAQ, SEDA's own RPVSP directory and scam alert, and Suruhanjaya Tenaga's own contractor and wireman registration pages — not from a marketplace listing, a reseller's marketing claim, or a secondary blog. Two claims we checked and rejected: a licence-class requirement for RPVSP registration that appeared only on one solar company's own marketing page, with no SEDA or ST source behind it; and a pair of uncited solar-scam statistics from the same kind of marketing blog, so no scam-rate figure of any kind appears on this page. Where our own research could not resolve a question against a primary source, this page says so rather than guessing.
