How Much Do Solar Panels Cost for a House in Malaysia? Guide)

“How much do solar panels cost?” is the single most common question we receive. The short answer: it depends on your house type, roof size, electricity consumption, and the component brands you choose. The detailed answer is in this guide — with three real-world scenarios based on actual Malaysian houses.

This is not a sales page. Our pricing page has exact package prices. This guide is educational — designed to help you understand what drives the cost, what you should expect to pay, and whether solar is a good financial decision for your specific situation.

What Factors Affect the Cost of Solar Panels for a House?

1. System Size (kWp)

This is the biggest cost driver. System size is determined by your monthly electricity consumption. A house with a RM300/month TNB bill needs around 5-6kWp. A house with RM800/month needs 12-15kWp. The bigger the system, the higher the cost — but also the bigger the savings.

2. Roof Type & Condition

Different roof types require different mounting systems. Metal/zinc roofs are cheapest to install on (clamp mounts). Clay/concrete tile roofs need rail mounts with tile hooks — slightly more expensive. Flat roofs require tilt frame structures to angle the panels correctly, adding RM1,000-3,000 to the cost.

3. Inverter Brand

The inverter is the second most expensive component after the panels. Three main brands in Malaysia:

• Solis: Best value — reliable performance, lowest cost
• Huawei SUN2000 (MAP0 series): Premium (+RM2,000) — best monitoring app (FusionSolar), AI-powered optimisation
• Sungrow: Premium (+RM3,000) — best for future battery storage integration

4. Location & Accessibility

Houses in the Klang Valley typically have the most competitive pricing due to installer density. East Malaysia (Sabah, Sarawak) costs 10-20% more due to logistics. Three-storey houses or difficult roof access may require scaffolding/crane (RM1,000-2,000 extra).

5. Electrical Infrastructure

If your house runs on single-phase power and you want a system larger than 6kWp, you will need a 3-phase upgrade from TNB (RM400-800). Older houses may also need electrical panel upgrades (RM300-800).

Scenario 1: Terrace House (RM18,499)

This is the most common scenario in Malaysia. A typical terrace house in Petaling Jaya, Shah Alam, or Subang Jaya has a south-facing rear roof of around 25-30 sqm — enough for 9-12 panels. The 5.58kWp system generates approximately 600-700 kWh/month, offsetting 60-80% of a typical terrace house's consumption.

Scenario 2: Semi-Detached House (RM28,000)

Semi-detached houses benefit significantly from solar because they have larger roof areas (40-60 sqm) and higher electricity consumption. The 12.40kWp system generates approximately 1,300-1,500 kWh/month. Most semi-D owners with this system size report TNB bills dropping from RM650 to under RM150.

Scenario 3: Bungalow (RM45,000)

Bungalows have the best solar ROI of any house type. Large roof areas (60-100+ sqm) allow for maximum system sizes, and the high consumption means every kWh of solar is displacing electricity at the most expensive TNB tariff tiers (54.60-57.10 sen/kWh). A 19.84kWp system generates approximately 2,100-2,400 kWh/month.

Solar Cost vs TNB Bill Over Time

The real question is not “how much does solar cost?” — it is “how much does solar cost compared to not having solar?”

The numbers are clear: over 25 years, the homeowner with solar saves RM185,000 compared to the homeowner without solar. And this is a conservative estimate — if TNB tariffs increase faster than 3% annually (which they have historically), the savings are even larger.

Financing Options — Monthly Payments Lower Than TNB Savings

You do not need RM20,000-45,000 upfront. Here is what the monthly payments look like with financing:

With Maybank's 0% promotional financing, your monthly loan repayment is roughly equal to your TNB savings — meaning solar is essentially free from Day 1. Note that EPF (KWSP) Account 2 withdrawals are not currently approved for solar panel purchases, so a green bank loan from Maybank, CIMB, RHB, Public Bank or BSN (rates from 3.5% p.a., tenures up to 10 years) is the standard path.

Government Incentives That Reduce Your Cost

Solar ATAP Bill Credit Programme

Solar ATAP is a bill credit mechanism — not a cash subsidy. When your solar panels generate more electricity than you consume, the excess is exported to the TNB grid and credited to your TNB bill at the Energy Charge rate (~RM0.218/kWh for domestic). Over a 10-year contract, these credits can significantly offset your electricity costs. Solar ATAP does not pay cash for panels or reduce the upfront system price. Read the full details on our incentives guide.

Green Technology Tax Incentive (GITA)

Business owners can claim a 100% capital allowance on solar equipment under GITA. This means the full cost of your solar system can be deducted from taxable income. For a company paying 24% corporate tax, a RM50,000 solar system effectively costs RM38,000 after the tax deduction. See our GITA tax guide for details.

What is Included in the Price?

When comparing quotes, make sure all of these items are included:

• Solar panels: Tier-1 Bloomberg panels (Jinko, LONGi, Trina) with 25-year warranty
• Inverter: SEDA-approved inverter with minimum 10-year warranty
• Mounting structure: Anodised aluminium rails and stainless steel hooks
• Balance of System (BOS): DC/AC cables, MC4 connectors, combiner box, surge protector
• Installation labour: CIDB-certified crew, typically 1-3 days
• SEDA application: NEM quota application and RPVSP submission
• TNB meter upgrade: Bi-directional meter for export metering
• Commissioning & testing: System performance verification and handover
• Monitoring setup: App configuration for real-time generation tracking

If a quote does not include any of the above items — or does not specify the exact panel and inverter model — be cautious. Read our guide on how to avoid solar panel scams.

The Bottom Line

Solar panels for a house in Malaysia cost between RM16,499 and RM50,000+ depending on your house type and system size. The payback period is 3-5 years. After that, you enjoy free electricity for 20+ more years.
