TNB Bill Before & After Solar: Real Savings in Malaysia

Wondering how solar panels will actually impact your TNB bill? You're not alone. Many Malaysian homeowners are curious about solar energy but unsure how it translates into monthly savings.

The good news? It's easier to understand than you might think. In this article, we'll walk you through what your TNB bill before and after installing a GetSolar system could look like — using a real customer example. We'll also explain how solar panels reduce electricity usage, and how to estimate your savings with our easy-to-use solar calculator.

Understanding Your TNB Bill Before Solar

Most Malaysian households still rely entirely on grid electricity from TNB. And with TNB's tiered tariff system, the more electricity you use, the higher your rate per kWh..

Here's how it works: TNB charges based on "block usage". Once your monthly usage goes above 600 kWh, your cost per unit jumps significantly. That means households with large families or heavy appliance use often see steep monthly bills.

Take this example from one of our customers before switching to solar:

They used around 844 kWh per month, resulting in a TNB bill of RM 365.02.

With electricity consumption rising year by year, more Malaysians are exploring solar panels as a long-term solution, especially with the support of  the Net Energy Metering (NEM) Rakyat 3.0 scheme.

What Changes After You Install Solar with NEM Rakyat 3.0?

Under the Net Energy Metering (NEM) Rakyat 3.0 scheme, solar energy isn't just for your own use — any extra electricity your system generates is exported to the TNB grid. In return, you receive bill credits that offset your future costs. Learn more about NEM Rakyat 3.0 and how it works.

So, What Does That Mean for Your TNB Bill?

Installing a solar PV system under the NEM Rakyat scheme let's you drastically reduce your monthly electricity bill. Here's how:

Let's say you install an 11-panel system that produces around 500 kWh/month. If your home consumes about the same amount (500 kWh/month), you could see savings of around RM330+ monthly.

But what if you don't use all that energy right away? No problem. Around 40% of solar energy is usually exported back to the grid, especially during the day when usage is lower. That exported energy is converted into credits, which then help lower your future bills.

Note: The NEM Rakyat 3.0 scheme operates on a quota system and the current quota is set to close by the end of June 2025. If you're considering solar, now's the time to act.

What Your TNB Bill Looks Like After Solar

Even without NEM Rakyat 3.0, going solar can still bring big savings —— especially if your household uses most of its electricity during the day.

How It Works

After installing solar, your TNB bill only reflects electricity drawn from the grid, typically at night- or on cloudy days. This is known as "import".

Meanwhile, the solar energy you use  directly during the day is called "self-consumption". It won't show up on your TNB bill, but it significantly reduces how much electricity you need to buy.

Real Example: Before vs After Solar

Here's a real TNB bill from a GetSolar customer who wen solar without NEM:

• Before Solar
  • Usage: 844 kWh/month
  • Bill: RM371.50
• After Solar
  • Usage from grid: 406 kWh/month
  • Solar self-consumption: ~300 kWh/month
  • New bill: RM28.75

That’s a monthly saving of RM340, just by using solar during the day — no export credits involved.

Maximise Savings With Self-Consumption

The biggest savings come from shifting daytime usage —— when rates are highest —— to solar. Appliances like:

• Air-conditioners
• Washing machines
• Water heaters

Will run on solar energy first. These are often the most energy-hungry, so replacing them with solar power brings immediate, ongoing savings.

Even without NEM, a well-designed system can reduce your electricity by  60-80%, just by powering your home more smartly.
