How much does solar really cost in Malaysia? We break down every component — panels, inverter, installation, permits — and show exactly what you should pay in 2026. Prices are reviewed monthly so you always get accurate benchmarks before requesting a quote.
All-in installed prices including panels, inverter, mounting, cabling, TNB Solar ATAP application, and SEDA registration. Prices vary by brand and site complexity.
| System Size | Price Range | Monthly Savings | Payback | Best For |
|---|---|---|---|---|
| 3 kWp | RM12,000 – RM15,000 | RM150 – RM250 | 5–6 years | Small home, bill RM150–250 |
| 5 kWpPopular | RM15,000 – RM25,000 | RM250 – RM400 | 4–6 years | Medium home, bill RM250–400 |
| 6.6 kWp | RM20,000 – RM30,000 | RM350 – RM500 | 4–5 years | Medium-large home, bill RM400–600 |
| 10 kWp | RM25,000 – RM40,000 | RM500 – RM800 | 4–5 years | Large home / small office |
| 50–100 kWp (Commercial) | RM150,000 – RM400,000 | RM5,000 – RM15,000 | 3–5 years | Factory, warehouse, shophouse |
Prices above are indicative all-in installed costs for peninsular Malaysia. Sabah and Sarawak add approximately 10–15% due to logistics. Commercial systems above 25 kWp are priced separately — see our commercial solar page.
The most reliable way to compare solar quotes in Malaysia is price per kilowatt-peak (kWp). A fair market rate in 2026 is RM3,000–4,000/kWp for a complete installed system.
This is the industry-standard benchmark for a quality residential installation using Tier-1 panels and a reputable inverter brand. If a quote is significantly below RM3,000/kWp, ask what corners are being cut.
| System Size | Low (RM/kWp) | High (RM/kWp) | Note |
|---|---|---|---|
| 3 kWp | RM4,000 | RM5,000 | Small system premium |
| 5 kWp | RM3,000 | RM5,000 | Sweet spot for homes |
| 6.6 kWp | RM3,030 | RM4,545 | Economies of scale kicking in |
| 10 kWp | RM2,500 | RM4,000 | Best value range |
| 50 kWp+ | RM3,000 | RM8,000 | Includes structural & compliance costs |
Two homeowners on the same street can receive quotes that differ by RM5,000–10,000. Here is why.
Larger systems have a lower cost per kWp but higher total cost. A 3 kWp system at RM14,000 costs RM4,667/kWp, while a 10 kWp at RM30,000 is only RM3,000/kWp.
High impactTier-1 TOPCon panels (JinkoSolar, LONGi, JA Solar) cost 10–20% more than Tier-2 brands but deliver better efficiency and longer warranties.
Medium impactHuawei SUN2000 commands a RM2,000–3,000 premium over Sungrow or Growatt. For most homes, Sungrow offers the best value.
Medium impactMetal deck roofs are cheapest to install. Concrete flat roofs need ballasted mounting (+RM1,500–3,000). Tiles require extra care.
Medium impactIf your main distribution board is far from the roof, cable runs add cost. Every 10m of DC cable adds roughly RM200–400.
Low–mediumSystems above 12 kWp typically require a three-phase supply. Upgrading from single-phase costs RM3,000–8,000 extra via TNB.
High impact (if upgrade needed)All five brands listed are Tier-1 Bloomberg-rated manufacturers. TOPCon technology is now the industry standard, offering better low-light performance and lower degradation rates than older PERC panels.
| Brand & Model | Technology | Efficiency | Warranty | Price / Watt | Rating |
|---|---|---|---|---|---|
JinkoSolar Tiger Neo Industry-leading warranty | TOPCon | 22.8% | 30 years | RM2.10 – RM2.40 | |
LONGi Hi-MO 7 World's #1 solar brand | TOPCon | 22.5% | 25 years | RM2.00 – RM2.30 | |
JA Solar DeepBlue 4.0 Best value Tier-1 | TOPCon | 22.4% | 25 years | RM1.90 – RM2.20 | |
Trina Vertex S+ Strong in commercial | TOPCon | 22.7% | 25 years | RM2.05 – RM2.35 | |
Canadian Solar HiKu7 Reliable, widely serviced | TOPCon | 22.5% | 25 years | RM2.00 – RM2.30 |
Why TOPCon is Now the Standard
TOPCon (Tunnel Oxide Passivated Contact) panels achieve higher efficiency and suffer lower annual degradation (~0.35%/year vs ~0.55% for older PERC) — meaning your 5 kWp system will still deliver over 4.5 kWp of output after 25 years. All major brands have now shifted their production lines to TOPCon, making it the default choice for new installations in 2026.
Trexon uses JinkoSolar Tiger Neo and JA Solar DeepBlue 4.0 as our primary panel brands. See the full breakdown on our best solar panels Malaysia guide.
The inverter converts DC power from your panels into AC power your home uses. It is the one component most likely to require service during the system's lifetime — so brand support matters.

For a typical 5 kWp residential system at RM20,000, here is how the budget splits across components and services.
The panels themselves account for the largest portion. TOPCon panels are now price-competitive with the older PERC generation, so upgrading technology adds minimal cost.
Huawei and Sungrow hybrids sit at the top of this range. String inverters from Growatt bring this percentage down to 12–15%.
Includes site survey, electrical work, panel installation, testing, and commissioning. Accounts for roof complexity — metal deck is fastest, flat concrete takes longest.
Anodised aluminium rail-and-clamp systems for standard roofs. Flat-roof ballasted systems add cost at this category.
Covers SEDA registration fee, TNB Solar ATAP application, TNB meter change coordination, and final sign-off documentation.
Most Malaysians finance their solar systems. At current TNB tariffs, your monthly savings often exceed the loan repayment — meaning solar can be cash-flow positive from day one.
Dedicated green financing products from Maybank, BSN, Bank Rakyat, and Bank Islam. Competitive rates, 3–10 year tenure.
Compare bank loansZero upfront cost. A financer owns the system; you buy electricity at a discounted rate. Ideal for commercial properties.

TNB raised the domestic base tariff by 13.64% in January 2026 — from 39.95 sen/kWh to 45.40 sen/kWh. Every unit of solar electricity you self-consume is now worth more, improving payback period by 6–12 months.
| Scenario | System | Annual Savings | Payback Period | 25-yr Lifetime Savings |
|---|---|---|---|---|
| Old (39.95 sen/kWh) | 5 kWp | RM3,000 | 5.5 years | RM75,000 |
| New (45.40 sen/kWh)Current | 5 kWp | RM3,410 | 4.8 years | RM85,250 |
