How Puan Nonie Cut Her TNB Bill 25% with a 17.36 kWp System

Key Takeaways:
Puan Nonie installed a 17.36 kWp GetSolar system on her landed home in September 2025. Six months later, her TNB bill was 25% lower and she had already recommended GetSolar to her neighbours without anyone asking her to.

In September 2025, Puan Nonie went solar with GetSolar. By April 2026 six months after her system went live, she had a  25% lower TNB bill and had already told her neighbours to do the same. Nobody asked her to.

That kind of unprompted recommendation is what a smooth end-to-end experience looks like. Here's the full story: what she had before, what she installed, how the process actually went, and what the numbers show six months in.

At a Glance

Why She Started Looking at Solar

Puan Nonie runs a high-consumption household, so the case for solar was straightforward: replace a large, growing recurring expense with a predictable fixed monthly payment and eventually own the system outright.

Before settling on GetSolar, she compared multiple other solar companies. She looked at what each one quoted, what was actually included, and what would happen if something went wrong post-installation.

"GetSolar ended up being our final choice because they offered the best savings and the easiest way to own our solar system." — Puan Nonie  

Our Rent-to-Own plan was the deciding factor: RM0 upfront, a fixed monthly payment, full ownership at the end of the term, and all maintenance covered throughout.

What She Installed: 17.36 kWp on a Landed Home

A 17.36 kWp system sits on the larger end of residential. The average Malaysian landed home installs between 6–10 kWp; Puan Nonie's system is roughly the size of a small commercial rooftop. That sizing makes sense for a household with high daytime consumption, such as multiple air-conditioners, a swimming pool pump, an EV charger, and more.

The system was designed around her actual consumption profile rather than offered as a standard package. That's part of why the savings landed in double-digit percentages rather than the more modest  reductions that oversized or undersized systems often produce.

Her Solar Journey: From Quote to Savings

The Installation Period

There was a 19-day gap between completing the physical installation and officially commissioning the system. This time was needed to clear the Solar ATAP paperwork (Malaysia's net metering programme that allows homeowners to export surplus solar energy back to the grid), conduct the TNB metering inspection, and swap the bidirectional meter.

Puan Nonie's feedback on the experience:

"From presales and site surveys to preliminary work, installation, and after-sales support, everything has been smooth and professional. They regularly check in to make sure our system is running well, and we're 100% satisfied with their service."

She explains it better than we can. In the three-minute interview below, Puan Nonie walks through how she compared providers, why she chose the Rent-to-Own plan, and what the installation process was actually like.

The Results: 25% Lower Bill Six Months In

April 2026 marks six months since Puan Nonie's system went live. By this point, the solar system had fully settled into its standard generation routine, and steady weather conditions provide a clean baseline for measuring normal output.

Hitting 25% off her TNB bill at the six-month mark is a strong result for a high-energy household. And this figure is just the starting point, savings typically climb further when homeowners shift power-hungry appliances like washing machines and dishwashers to daytime hours.

The Long-Term Picture

A 25% bill reduction at month six is a great start, but the real value builds over time.

Under our Rent-to-Own plan, Puan Nonie pays a fixed monthly amount with all maintenance fully covered. Once the term ends, she owns the system outright and continues generating her own electricity for the remainder of the panels' 25-year warranted lifetime.

For a high-consumption household with a system this size, that can translate to well over RM200,000 in cumulative savings across 25 years though actual figures vary depending on usage, system performance, and future TNB tariff movements.

With the AFA (Imbalance Cost Pass-Through, a quarterly fuel-cost adjustment on your TNB bill) recently revised upward and a TNB tariff review on the horizon, locking in your own generation now means you generate a portion of your electricity free from those adjustments for the next two decades.

Her Verdict

Puan Nonie's Google review, in her own words:

"I recently had a solar PV system installed by GetSolar Sdn Bhd, and I couldn't be happier with the experience. From the initial consultation to the final installation, the team was professional and truly committed to making the whole process smooth and efficient. They communicated well throughout the process, addressing any issues that had cropped up and ensuring that I was kept in the loop and confident in their work. I've already noticed a difference in my energy bills. I highly recommend GetSolar for anyone considering solar installation. They made the transition to renewable energy a positive and reassuring experience."
