Emit Solar | Home Solar Panels | Easy Ownership
It sounds fantastic. But the real question is – how did they get to that number? Behind every solar savings estimate is a stack of assumptions. Some are realistic. Some are quietly optimistic. Some make the quote look better than it should. Here’s what to check before your trust the numbers.
Under the new tariff structure effective July 2025 and Solar ATAP rules, higher usage households generally see stronger returns than lower usage ones.
The system may cost the same, but the value of the electricity it produces does not.
“The cost of a solar system is the same whether you use 200 kWh or 2,000 kWh a month. But the return is not.”
Why high users win with ATAP
Three mechanics drive the gap. They compound on each other, and understanding them helps you know exactly where you stand.
1 .They avoid more expensive electricity
Homes that use more than 1,500kWh a month pay a higher Energy charge (37.03sen/kWh) than those that do not (27.03 sen/kWh). So when a high-usage home uses solar directly, every unit replaces electricity that would have otherwise cost more. That gives the same solar electricity a higher financial value.
2. Lower users already receive help through the EEI rebate
The Energy Efficiency Incentive (EEI) provides rebates to households using up to 1,000kWh a month. The lower the consumption, the higher the rebate can be. For example, users consuming 200kWh and below receive 25 sen/kWh in rebates. It is genuinely good policy as it helps keep electricity affordable. But it also lowers the cost of electricity that solar would replace.
In simple terms:If TNB electricity is already heavily discounted, each solar kWh saves you less. This is one reason low-consumption households often face longer solar payback periods.
3. Direct usage is worth more than export
Solar panels generate electricity during the day. If you’re home during the day – running air conditioning, appliances, a water heater – you consume that electricity directly, saving at your full tariff rate. High-use households typically use significantly more electricity during daylight hours. Low-use households often export most of their generation back to the grid, where the Solar ATAP offset rate is lower than their direct consumption saving would have been.

The same 5kWp solar system. The same installation cost. Different payback timelines.
The bottom line
As of today, solar is still financially beneficial for most Malaysian homes. But if you’re a high user, your returns are significantly stronger.
The Honest Answer
Solar ATAP is available to many households, but it does not deliver the same financial returns to everyone. Today, it generally works best for homes that:
- have higher electricity usage
- use more electricity during the day
- pay less-discounted tariff rates
- can use most of the system’s generation
For lower-usage homes, system sizing and future consumption matters much more.
That is because your bill may grow over time, either from higher electricity prices or higher household consumption – more air-conditioning, an EV charger, or more people at home. So a system that looks like a 6-year payback today based on your current usage could become a 4–5 year payback if your consumption grows.
Should Your Home Go Solar?
The answer should come from your own usage.
Use our Solar ATAP calculator to adjust your:
-monthly TNB bill
-direct solar usage
-system size
Then see whether Solar ATAP makes sense for your home.
