TL;DR: Our top 5 solar companies in Malaysia for 2026 are Solarvest, Pekat Group, Samaiden, Sunview Group and EDCA Energy. The first four are Bursa Malaysia-listed EPCC groups with large-scale solar track records; EDCA Energy is the specialist pick for homes, SMEs and C&I rooftops in the Klang Valley and Johor. We ranked on public filings, SEDA registration, segments, warranties and after-sales, then added a quote checklist.
Search for the top 5 solar companies in Malaysia and you get a dozen near-identical lists, usually written by a company on the list and rarely explaining the order. This one does. Every company fact below comes from a Bursa Malaysia filing, a government page or reputable press, and the ranking rules come before the ranking.
It is for homeowners, business owners and facility managers who need to shortlist two or three solar companies in Malaysia and compare their quotes properly. We cover the five companies, the criteria, the market under Solar ATAP, and the questions that expose a weak installer. For the credentials themselves, see our guide on what to look for in a solar panel installer.
First, a short video on the questions worth asking any solar company before you sign — the principles travel, even though licences and schemes differ in Malaysia.

1How we ranked the top 5 solar companies in Malaysia
Quick Answer: We ranked the top 5 solar companies in Malaysia on six things you can check yourself: SEDA registration, public track record, segments served, warranty terms, after-sales support and financing. Listed companies rank higher because their scale is audited and published. Our guide to comparing solar panel installation companies shows how to weigh these for your own shortlist.
Each rule maps to something a buyer can verify without inside knowledge:
- SEDA registration. Under Solar ATAP, SEDA keeps directories of Registered PV Service Providers (RPVSP) and Registered Solar PV Investors (RPVI). Only registered providers can take your rooftop application through the scheme, per the official Solar ATAP page.
- Public track record. Listed groups publish audited revenue and project wins; private firms are judged on documented portfolios and certifications.
- Segments served. Home, C&I rooftop, large-scale solar (LSS), battery storage, EV charging and O&M.
- Warranty, after-sales and financing. Workmanship warranty length, monitoring, in-house O&M, and leasing or power purchase options.
One honesty note: EDCA Energy publishes this list, so we placed ourselves where the facts put us — as the specialist pick, not the biggest player.
Key takeaway: Judge any “best solar company in Malaysia” list by whether you can check its claims. Ours uses SEDA registration, public filings, segments, warranties, after-sales and financing — all verifiable.

1. Solarvest Holdings Berhad
Founded in 2012 and headquartered in Petaling Jaya, Solarvest was among the first grid-tied installers certified by SEDA, ISPQ and GCPV, per MIDA.

2. Pekat Group Berhad
Pekat listed on the ACE Market in June 2021, raising RM44.4 million, per Focus Malaysia. Solar PV, one of four divisions alongside power distribution, earthing and lightning protection, and trading, gave 54.6% of first-half 2026 revenue, led by LSS EPCC, per The Edge Malaysia.
3. Samaiden Group Berhad
Samaiden debuted on the ACE Market on 15 October 2020 as an EPCC specialist for solar PV systems and power plants, reported by The Borneo Post, and won Main Market approval in March 2023, per The Edge Malaysia. Its focus is C&I and utility-scale work.

4How big is Malaysia’s solar market in 2026?
Quick Answer: Malaysia reached about 5,777 MW of cumulative solar capacity by end-2025, split almost evenly between large-scale solar (2,648 MW) and net energy metering rooftops (2,747 MW), with 345 MW under the older feed-in tariff. New rooftop demand now runs through Solar ATAP, which our commercial solar installation page explains for businesses.
The split matters when choosing among the top 5 solar companies in Malaysia: LSS is won through tenders by large EPCC groups, while rooftop capacity is built one building at a time by installers of every size. Data: IEA-PVPS figures reported by pv magazine.
| Scheme | Capacity (MW) | Who builds it |
|---|---|---|
| Net energy metering (NEM, three rounds) | 2,747 | Rooftop installers of all sizes |
| Large-scale solar (LSS) | 2,648 | Large EPCC groups via tender |
| Feed-in tariff (FiT) | 345 | Legacy scheme, closed to new entrants |
| Total | 5,777 | Excludes off-grid systems |
Source: IEA-PVPS figures as reported by pv magazine, 3 April 2026. Compiled by EDCA Energy.
Nearly half of Malaysia’s solar sits on rooftops. Since 1 January 2026, new rooftop systems go through Solar ATAP, which caps domestic systems at 5 kW single-phase or 15 kW three-phase and non-domestic systems at 1,000 kW, per SEDA. Any solar installer in Malaysia you shortlist should explain those limits without checking.
Key takeaway: Rooftop solar is as large as utility-scale solar in Malaysia. Choose a company fluent in Solar ATAP rules, not only in large-scale tenders.
5How fast has Malaysia’s solar capacity grown?
Quick Answer: Malaysia’s installed solar capacity grew from about 996 MW at end-2020 to roughly 5,777 MW at end-2025 — close to six-fold in five years. Growth came from both LSS tenders and rooftop schemes, which is why experience with large-scale solar farms and rooftops now sits inside the same companies.
A fast-growing market is good for prices and hard on quality control, because new installers arrive faster than track records form. The series compiles year-end figures from different published sources, so read it as a trend line.
| Metric | 2020 | 2021 | 2024 | 2025 |
|---|---|---|---|---|
| Cumulative capacity (MW) | ~996 | ~1,700 | 4,329 | 5,777 |
| Source | Fitch Solutions | IRENA | IEA-PVPS | IEA-PVPS |
Compiled by EDCA Energy from TaiyangNews (2020), PV Tech (2021) and pv magazine (2024–2025). 2022–2023 omitted: no consistent year-end total published.
In 2021 Fitch forecast 4 GW by 2030; Malaysia passed it in 2024.
Key takeaway: Capacity has grown roughly six-fold since 2020. In a market this hot, years in operation and completed-project count matter more than marketing when picking from the top 5 solar companies in Malaysia.
6How to get and compare solar quotes from the top companies
Quick Answer: Get three quotes from a mix of company sizes, give each the same 12 months of TNB bills and roof details, then compare price per kWp, equipment brands, warranty years and exclusions. Our breakdown of solar panel cost in Malaysia gives the price ranges to sanity-check against.
Quotes only compare fairly when every company answers the same brief. Use this sequence whether you approach a listed group from the top 5 solar companies in Malaysia, a regional installer or EDCA:
- Collect your inputs. Twelve months of TNB bills, photos of the roof and meter board, and your roof type, so each company sizes to your real load.
- Shortlist three companies of different sizes. One large listed group, one specialist and one other, all confirmed on the SEDA RPVSP directory linked from the SEDA portal.
- Ask for a site visit, not a WhatsApp quote. Shading, structure and cabling runs cannot be judged from a photo.
- Normalise the quotes. Divide total price by kWp, then list panel and inverter models, mounting type, workmanship warranty years, and whether the Solar ATAP application and TNB meter fees are included.
- Compare after-sales before price. Monitoring app, fault response time, O&M plan and whether crews are in-house. Only then compare price per kWp.
Key takeaway: Same brief, same inputs, same checklist for every one of the top 5 solar companies in Malaysia you approach. Compare price per kWp last.

7How should you score solar quotes side by side?
Quick Answer: Score each quote out of 100 across six weighted criteria — credentials, equipment, warranty, after-sales, price and financing — with price worth no more than a quarter. The illustrative grid shows how a cheap quote can lose to a dearer one. Our guide to what to look for in a solar panel installer explains each criterion.
The weights are EDCA’s suggested starting point; the three quotes are made up to show the method. Keep price below 30% or the exercise simply rewards the lowest bidder.
| Criterion (weight) | Quote A: lowest price | Quote B: specialist EPCC | Quote C: large group |
|---|---|---|---|
| Credentials (20) | 10 | 20 | 20 |
| Equipment tier (20) | 12 | 18 | 18 |
| Workmanship warranty (15) | 5 | 14 | 12 |
| After-sales and O&M (15) | 5 | 14 | 10 |
| Price per kWp (20) | 20 | 15 | 12 |
| Financing options (10) | 4 | 8 | 10 |
| Total (100) | 56 | 89 | 82 |
Illustrative scoring by EDCA Energy; quotes A, B and C are hypothetical, not real companies or prices.
Quote A wins on price and still finishes last, because a short workmanship warranty and thin after-sales cost more over 25 years than the day-one saving.
Key takeaway: Weighted scoring stops the lowest price deciding by default. Set the weights before the quotes arrive so they do not drift towards whichever company pitched last.
8Red flags and questions to ask any solar company in Malaysia
Quick Answer: Walk away from any solar company that cannot show current SEDA registration, asks for full payment upfront, quotes without a site visit, or will not name panel and inverter models in writing. Then ask who services the system in year five — a company with its own solar panel maintenance team has an answer.
Most solar problems in Malaysia are installer failures: roof leaks, undersized cabling, late applications, or a company that stops answering. SEDA has published an alert on net metering scams, so the risk is real. Ask these of every company, including the top 5 solar companies in Malaysia above.
Red flags that should end the conversation:
- No verifiable SEDA registration. “Pending” or “through a partner” is not registration.
- 100% payment before installation. Established companies stage payments against milestones.
- Pressure pricing. “Valid today only” is a sales tactic, not a market condition.
- No brand or model on the quote. You cannot compare equipment or check warranty support without them.
Questions that reveal the real company behind the pitch:
- Who files my Solar ATAP application, and how many have you completed this year?
- Are your crews employees or subcontractors, and who supervises them on site?
- What exactly does the workmanship warranty cover, and for how many years?
- If the inverter fails in year six, who do I call and how fast do you respond?
Key takeaway: The right questions cost nothing and filter out most weak installers before a quote is priced.
9Conclusion
The top 5 solar companies in Malaysia for 2026 share the traits that matter: SEDA registration, a checkable track record, clear segment focus and real after-sales. Solarvest, Pekat Group, Samaiden and Sunview Group bring listed-company scale on large-scale and C&I work; EDCA Energy brings specialist attention to homes, shops, offices and factories in the Klang Valley and Johor.
Whichever names you shortlist, use the same brief, scoring grid and questions for each. If one quote should come from a SEDA-registered specialist, EDCA Energy will survey your roof and prepare a free, itemised proposal you can score against the rest.

10Frequently asked questions
Which is the best solar company in Malaysia?
There is no single best solar company in Malaysia for every project. Among the top 5 solar companies in Malaysia, the listed EPCC groups lead on large-scale and large commercial work, while EDCA Energy specialises in home and C&I rooftops. Pick the one whose segment focus, SEDA registration, warranty and after-sales match your roof.
How do I check whether a solar installer is SEDA-registered?
Search the company name in SEDA Malaysia’s Registered PV Service Provider (RPVSP) directory, linked from the SEDA net metering and Solar ATAP pages. The listing should show an active status with an unexpired renewal date. If the company is not listed, it cannot take your rooftop application through Solar ATAP.
How many solar quotes should I get before choosing?
Three is the practical number. Give each company the same 12 months of TNB bills and roof details, ask for a site visit, then compare price per kWp, equipment, workmanship warranty and after-sales on one scoring grid. More than three rarely changes the decision.
Is a listed solar company safer than a private one?
A Bursa Malaysia listing proves scale and audited accounts, which reassures on large contracts, but it does not guarantee attention on a small rooftop. A private specialist with SEDA registration, ISO 9001 certification, a documented portfolio and its own maintenance team can be equally safe for a home or SME project.
What warranty should a Malaysian solar company offer?
Expect three layers: a manufacturer product warranty on panels and inverter, a 25-year panel performance warranty, and the installer’s own workmanship warranty covering mounting, waterproofing and wiring. The workmanship warranty is the one the installer controls, so compare its length and written scope across quotes.
