Solar Installer Malaysia: A Homeowner's Checklist

Key Takeaways:
‍The cheapest quote is almost never the best one. Credentials, equipment, warranty, track record, financing, after-sales support are what separate a competent installer from a random operator. Get the wrong one and your RM 25,000 system could become a 25-year headache.

Get three quotes for the same roof in Malaysia and they can come back at RM 18,000, RM 26,000, and RM 34,000. Most homeowners read that as a pricing problem. It's not. It's an installer problem.

Solar panels are largely commoditised — LONGi, JA Solar, Jinko, and Huawei dominate most quotes. What you're actually paying for is everything around the panels: the design, the install quality, the warranty that's honoured when something breaks, and the team that picks up the phone seven years from now.

Get that part wrong and a RM 25,000 system becomes a 25-year headache. Get it right and your panels quietly knock 70% off your TNB bill for the next quarter-century.

Here's the checklist to separate the two.

Why the Installer Matters More Than the Panel Brand

Most Malaysian homeowners fixate on panel brand when they should be more focused on who's installing them instead.

The big panel makers produce reliable kit. Failures are rare, and when they happen, warranty replacements are straightforward.

Installation failures, whether it's leaky roofs, undersized cables, shoddy mounting, or inverters placed in direct sunlight, are neither rare nor straightforward. They cost money to fix, and the installer who caused them is often the one who stops answering calls.

The checklist below will be your guide in finding the right solar installer.

1. Credentials: SEDA, CIDB, and MyHIJAU

Malaysia has a formal registration system for solar. Use it.

• SEDA Registered PV Service Provider (RPVSP) — required for any installer submitting Solar ATAP application on your behalf. Check the public list on SEDA's website before you sign.
• CIDB licence — required for construction work. No CIDB, no legal install.
• MyHIJAU registration — confirms the installer deals in certified green products, which matters for GITA (Green Investment Tax Allowance) and other incentive claims.

If an installer cannot provide their RPVSP number on the spot, it’s best to reconsider.

2. Equipment: What's Actually on Your Roof

Ask for the exact panel and inverter model in writing, on the quote itself.

Panels. Tier-1 monocrystalline from LONGi, JA Solar, Jinko, Trina, or Canadian Solar are  bankable brands — rated on the Bloomberg New Energy Finance (BNEF) Tier-1 list, which means banks are willing to finance projects using them.

Inverters. Huawei, GoodWe, Sungrow, SMA, or Solis are the common reputable choices in Malaysia. String inverters cost RM 3,000 to RM 5,000; microinverters or optimisers are RM 5,000 to RM 8,000 and make sense if your roof has shading or multiple sections.

Warranty on both. Panels should carry a 12-year product warranty and a 25-year performance warranty. Inverters typically come with 5 to 10 years, extendable. Anything shorter than that is a red flag.

3. Warranty: Get It in Writing

Verbal warranties mean little. Demand a written warranty document that specifies:

• What's covered (panels, inverter, mounting, cabling, labour)
• Who honours it (the manufacturer or the installer, sometimes both)
• How long each component is covered for
• The claims process, including who pays for labour if a replacement is needed

Installers may quietly exclude labour costs from warranty claims. A panel replacement under manufacturer warranty still costs RM 1,500 to RM 3,000 in labour if your installer isn't handling it. Confirm this in writing before you sign.

4. Track Record: Ask for Three Recent Installs

Every installer will tell you they're experienced. Ask for specifics:

• Three recent residential installs in your area (same house type if possible)
• Photos of the actual install work, including mounting and cable routing
• Years in business, and number of residential projects completed

A good installer will share this without hesitation. The details of their past work will tell you more than any sales pitch.

5. Financing: Is the Price Actually Real?

The quote you receive should be all-in. Confirm these items are included and not added on afterwards:

• Solar ATAP application and submission
• TNB meter change coordination
• Electrical wiring and DB board upgrades where needed
• Scaffolding (RM 1,500 to RM 3,000 for multi-storey homes)
• Roof waterproofing at the mounting points
• Monitoring platform setup

Missing any of these means the RM 20,000 quote becomes RM 24,000 by handover.

If you're considering financing, compare the options openly. Solar loans from Maybank, Bank Rakyat, BSN and others give you up to RM 400,000 at competitive rates. A Rent-To-Own (RTO) plan gets you the system at RM 0 upfront, with free maintenance throughout the contract.

6. After-Sales: The Part Nobody Asks About

Solar is a 25-year commitment. The question is whether your installer will still be around in year eight when your inverter starts acting up.

Ask for:

• An online monitoring platform or app with real-time performance tracking
• A documented maintenance schedule and per-visit cost
• Response time commitments for fault reporting
• A physical office you can visit

Installers offering Rent-To-Own generally have stronger after-sales, because they're financially on the hook for system performance for the full contract period.

Red Flags That Should End the Conversation

Some patterns are disqualifying. Walk away if:

• The salesperson won't leave without a deposit today
• No site survey offered before the quote
• Panel and inverter models aren't named in the written quote
• The warranty is described verbally but not in writing
• There's no physical office address
• The price is suspiciously below market without a clear explanation

The Right Installer Pays for Itself

Choosing a solar installer in Malaysia is a 25-year decision you make in about two weeks. The right installer might cost RM 2,000 to RM 4,000 more upfront and will save you ten times that over the system's lifetime through better design, cleaner installation, and warranty claims that actually get honoured.

GetSolar works only with Tier-1 panels and inverters, provide full written warranties, runs a live monitoring platform, and cover lifetime maintenance on our Rent-To-Own plan.

What a Reasonable Quote Looks Like in 2026

For sanity-checking what you receive, here's the realistic market range for Malaysian landed homes as of early 2026:

Source: GetSolar Malaysia 2026 Cost Guide. Prices expected to rise ~15% from April 2026 onward due to China's removal of the 9% VAT export rebate on PV products.

If a quote comes in significantly below this range, something's been excluded such as cheaper panels, thinner cabling, a no-name inverter, or a warranty that doesn't survive the first claim. If it comes in well above, make sure the extras justify the premium.
