Update: NEM Has Ended, Solar ATAP Takes Over

2026 update: The NEM (Net Energy Metering) scheme officially ended on 30 June 2025 and is no longer accepting new registrations. The current replacement programme is Solar ATAP (Solar Accelerated Transition Action Programme), effective from 1 January 2026, with cash rebates up to RM3,000 through SuRIA Home.

How Solar Panels Work in Malaysia: What Are Solar Panels?

Solar panels are devices made of photovoltaic cells that capture sunlight and convert it into electrical energy. Because Malaysia enjoys strong solar radiation, solar energy Malaysia systems perform efficiently even during cloudy days.

How Solar Panels Work in Malaysia: How Electricity Is Generated

The process of generating electricity using solar panels is actually quite simple.

1. Solar Panels Capture Sunlight

Solar panels installed on your roof absorb sunlight during the day. The photovoltaic cells inside the panels convert solar energy into direct current (DC) electricity.

2. Inverter Converts DC to AC Power

Homes and offices use alternating current (AC) electricity, not DC. This is where the inverter plays an important role.

The inverter converts the DC electricity generated by the solar panels into AC electricity that can power:

Air conditioners
Refrigerators
Lights
TVs
Washing machines
Office equipment

3. Electricity Powers Your Home

Once converted, the electricity is used immediately by your home or building. This reduces the amount of electricity you need to purchase from TNB.

The more solar energy your property produces, the lower your electricity bill becomes.

4. Excess Energy Can Be Sent Back to the Grid

In Malaysia, the Net Energy Metering (NEM) program allows homeowners and businesses to export excess solar energy back to the TNB grid.

This means:

Extra electricity generated during the day is not wasted
You receive energy credits from TNB
These credits help offset your future electricity usage

This system makes solar even more cost-effective in the long term.

Why Solar Power Works Well in Malaysia

Malaysia’s tropical climate provides strong sunlight almost all year round, making it an ideal location for solar energy systems.

Benefits of Malaysia’s climate for solar:

High solar radiation throughout the year
Consistent sunlight exposure
Long daylight hours
Reduced dependence on fossil fuels

Even during cloudy weather, solar panels can still generate electricity, although at a lower efficiency.

The suitability depends on factors such as roof size, sunlight exposure, and monthly electricity usage.

Now that you understand how solar panels work in Malaysia, here are some common questions homeowners ask before installing a solar system.

FAQ: Solar Panels Malaysia

Q: Do solar panels work during rainy days?

A: Yes. Solar panels still generate electricity during cloudy or rainy weather, although efficiency may be lower compared to sunny days.

Q: Can solar panels reduce my TNB bill to zero?

A: Depending on your energy usage and system size, solar panels can significantly reduce or even eliminate your electricity bill.

Q: How long do solar panels last?

A: Most solar panels have a lifespan of 25 years or more.

Q: Is solar maintenance expensive?

A: Solar systems generally require minimal maintenance, mainly occasional cleaning and inspections.

Q: Do I need batteries for a solar system?

A: Not necessarily. Most grid-connected solar systems in Malaysia work without batteries through the NEM program.
