Introduction: Why Solar Installation Is Booming in Malaysia
Over the past few years, Malaysia has seen a surge in solar adoption — and for good reason. With rising electricity costs and increased environmental awareness, homeowners and businesses are turning to solar energy as a sustainable and cost-saving solution.
But what exactly goes into solar panel installation in Malaysia? Is it complicated, expensive, or worth it in the long run?
This guide by Gen Solar breaks down everything you need to know — from how installation works, what it costs, and what to expect before switching to solar.
Understanding Solar Panel Installation
Solar panel installation is the process of mounting photovoltaic (PV) panels on rooftops or open areas to convert sunlight into usable electricity. The process involves several key components:
- Solar panels: Capture sunlight and convert it into DC electricity.
- Inverter: Converts DC to AC, which powers your home.
- Mounting system: Secures panels safely to your roof.
- Cables & isolators: Ensure energy flow and safety.
- Monitoring system: Tracks real-time energy production and savings.
At Gen Solar, we specialise in turnkey installations — handling everything from design to approval so you can enjoy a hassle-free transition to clean energy.
🏠 The Solar Installation Process (Step-by-Step)
Going solar may sound complicated, but with the right provider, it’s simple and stress-free. Here’s a breakdown of what to expect:
1. Site Assessment & Energy Review
We begin by understanding your home’s energy needs and reviewing your latest TNB bill. This helps determine your ideal system size (kWp).
👉 Example: A home with RM300 monthly usage typically benefits from a 5–6kWp system.
2. System Design & Proposal
Our team designs a customised system using premium brands such as LONGi panels and Solis inverters — chosen for their proven performance in Malaysia’s hot and humid climate.
3. Quotation & Savings Estimate
You’ll receive a transparent proposal detailing system cost, estimated savings, and payback period. No hidden fees — installation, materials, skylift, and labour are all included.
4. SEDA & TNB Approval
We handle all the necessary paperwork and submission to SEDA Malaysia for the Net Energy Metering (NEM)program. Once approved, installation begins.
5. Installation (Within 30 Days)
Our SEDA-registered installers ensure precise and safe installation — usually completed within 30 days of approval.
6. Testing & Commissioning
Before activation, we test every connection and inverter reading to ensure optimal performance.
7. System Activation & Monitoring
Once TNB connects your system, you’ll start generating your own power! You can monitor performance anytime using your inverter app.
💰 How Much Does Solar Installation Cost in Malaysia?
The cost depends on system size, brand, and roof type. Here’s a rough estimate:
| System Size (kWp) | Ideal for | Estimated Cost (RM) | Monthly Bill Savings |
|---|---|---|---|
| 4kWp | Small homes | RM12,000 – RM14,000 | RM120 – RM180 |
| 6kWp | Medium homes | RM16,000 – RM18,000 | RM150 – RM250 |
| 10kWp | Large homes | RM25,000 – RM30,000 | RM300 – RM400 |
Bonus Tip: With NEM 3.0, excess power generated can be exported back to the grid for credits — reducing your TNB bill even further.

Factors That Affect Solar Installation Cost
When comparing quotes, keep these key factors in mind:
- Roof Type & Structure: Concrete, metal, or tile roofs affect mounting design.
- System Capacity: The larger the system, the higher the cost — but also higher savings.
- Equipment Brand: Premium brands (LONGi, Jinko, Solis) cost slightly more but last longer.
- Warranty & After-Sales: Always choose providers offering at least 10–30 years of warranty coverage.
- Labour & Safety: Ensure your installer includes labour, skylift, and safety tools in the quotation.
🛠️ Why Choose Professional Installation?
Some homeowners consider DIY installations to save cost, but professional installation ensures:
- Safety: Working on rooftops and live systems requires certified expertise.
- Efficiency: Proper tilt and orientation boost power output.
- Compliance: Only licensed installers can get SEDA/TNB approval for NEM.
- Warranty Protection: Manufacturer warranties often require certified installation.
With Gen Solar, you’ll have local experts who guarantee top-quality installation and reliable after-service.
🌦️ How Malaysia’s Climate Affects Installation
Malaysia’s tropical weather offers abundant sunlight but also challenges like heat, humidity, and rain.
That’s why we use climate-tested components designed for tropical durability — including corrosion-resistant frames and IP66-rated inverters.
Our team ensures every installation is climate-ready, so you enjoy dependable performance all year round.
