Malaysia solar: compare installers, home and factory quote scenarios
Decision details
In this guide
Looking for a solar calculator? Use the T10 sizing calculator for a preliminary panel-capacity estimate from bill kWh. This hub’s scenario calculator compares your entered proposal, usage and payment assumptions; it does not size a roof or issue a quote. Use the quote worksheet guide to collect and compare those assumptions before asking installers.
Which solar route fits a home, shop or factory?
| Your premises | Evidence to bring | Decision to make |
|---|---|---|
| Home | Electricity bills showing kWh, daytime occupancy, roof and supply phase | Size for usable generation; compare outright purchase with the actual financing payment |
| Shop / SME | Opening hours, daytime load, weekends, roof lease and electricity account | Compare ownership with a PPA on the same load and contract term |
| Factory / warehouse | Interval load, production shifts, billed maximum demand (MD), roof condition and planned expansion | Separate energy savings from any evidenced MD reduction; check roof tenure and contract exit costs |
For a physical sizing estimate, use actual kWh and a site-specific yield assumption. For business solar, ask which connection scheme applies. Business premises are not automatically limited to SelCo; the applicable approval and export terms belong in the proposal.
Which Malaysian solar brands should I compare?
This shortlist helps request comparable evidence. It is not a performance ranking: website service descriptions do not measure installation quality, your final price or after-sales response. Brand and service pages were reviewed on 5 October 2026; GSPARX’s current page could not be retrieved for this review.
| Provider / primary source | Publicly presented route | Ask before choosing |
|---|---|---|
| Verdant Solar | Residential and commercial / industrial routes | Exact equipment, roof work, payment milestones and projected self-use |
| Solarvest | Residential, commercial and utility project routes | Which contracting entity and installation team will deliver your project? |
| Plus Xnergy | Solar and energy-management solutions | Separate solar cost from storage or energy-management extras |
| SOLS Energy | Home and business solar | Compare purchase and any offered contract using total payments and exit terms |
| GSPARX | Current offer verification pending | Request current scheme, equipment, coverage and contract terms directly |
| Next Energy | Residential installation | Named installation team, exact inverter and local warranty responsibility |
| MAQO Solar | Residential solar and battery options | Which circuits operate during an outage, and for how long? |
| Trexon | Online pricing and bill-led proposal flow | Does the quoted scope match your roof, phase and generation assumptions? |
Our commercial relationship: Betulkex has a Verdant referral route and may earn a commission if a referred project proceeds. The named home referral option below goes to Verdant, rather than sending your enquiry to this entire shortlist. Business-project referral eligibility remains unconfirmed. We do not claim Verdant is cheapest or best for every property.
How do I compare two solar quotes fairly?
| Comparison row | Record the same basis | Why it changes the decision |
|---|---|---|
| System and equipment | DC panel capacity in kWp; AC inverter output in kWac; exact models | Panel capacity and inverter output are different measures |
| Complete installed scope | Roof work, waterproofing, cables, protection, applications, meter work and exclusions | A lower headline price can leave substantial work outside the contract |
| Usable energy | Estimated generation, on-site use and usable export credit for the same period | Generation is not the same as bill savings |
| Payments | Deposit, milestones, financing / PPA payments, maintenance and termination costs | Compare your cash obligations, not the provider's advertised system value |
| Warranty and support | Product, performance, workmanship and roof-leak terms; who handles each claim | A panel performance warranty does not cover every repair or labour cost |
Our home quotation guide covers the buying checks. Verdant’s own quote-comparison guide is also useful for understanding its proposal structure. Ask each installer to explain assumptions in writing before comparing its payback headline.
How should I use the Betulkex solar scenario calculator?
The calculator below compares self-use only, your entered export case and your chosen stress case. Enter figures from a written proposal and a load assessment, including usable export-credit limits. Enter zero for an unconfirmed rebate. The tool annualises one representative month and subtracts your payments and operating costs; seasonal production, degradation, replacements, interest changes and resale value need a separate lifetime model.
For SelCo, use zero export credit. For a PPA, enter your actual payment and your own upfront cost; do not also count capital paid by the provider. Factory MD savings and tax relief are excluded: ask for separate evidence rather than assuming solar lowers the billed peak.
When does a battery change the decision?
Decide whether the goal is backup, higher self-use or a tariff-specific energy shift. Compare the additional battery cost and replacement exposure against that benefit. A standard grid-tied installation does not establish blackout backup; request the supported circuits, usable capacity, transfer arrangement and installer demonstration. See the battery guide.
What should I verify about tariffs, approvals and location?
Use the current Energy Commission guidelines, TNB tariff information and SEDA programme information for your account and connection scheme. Confirm the current rebate window before including it in a budget. Older NEM examples and last month’s AFA are not a current quote basis. Sabah and Sarawak require the relevant local utility rules, rather than an automatic TNB assumption.
What if I want off-grid solar?
Distinguish a fully isolated system from a grid-connected installation that prevents export. Record critical loads, operating hours, motor starting demand, required autonomy and backup supply. Ask a competent installer for a single-line diagram, protection, earthing, isolation and battery ventilation arrangements. A marketing label does not establish the system’s legal or safety position. A larger battery alone does not resolve these design questions.
Betulkex solar quote scenario: home, shop or factory
Use figures from your proposal and load assessment. Enter zero where no credit or rebate has been confirmed.
Inputs are your scenario assumptions, not measured results. Use the incremental import saving applicable to your tariff, excluding fixed charges that remain payable. For factories, this calculation excludes MD savings and tax relief. Under SelCo, enter zero export credit. A PPA payment is the actual quoted payment; do not also count the provider’s system cost as your capital.
