With the introduction of the Solar Accelerated Transition Action Programme (ATAP) policy by TNB, many homeowners are re-evaluating how to maximise their solar investment.

One key change is the offset structure, excess solar energy exported to the grid is now credited based only on the energy charge component, rather than the full tariff and additionally, it cannot be carried forward to the following months.

Currently, the offset rates are:

• RM0.27/kWh for monthly usage below 1,500 kWh
• RM0.37/kWh for usage above 1,500 kWh

This shift has sparked an important question: Is it still worth installing a battery storage system?

Understanding the impact of the new policy

Previously, homeowners could enjoy 1 to 1 offset value basis from exporting excess energy to the grid. With the revised structure, the compensation is lower, meaning:

• Exporting energy is less financially attractive
• Self-consumption becomes more important than ever

In simple terms, the more solar energy you use directly, the more you save.

So, should you install a battery energy storage system (BESS)?

A battery stores excess solar energy for later use, mostly at night, helping you reduce reliance on TNB’s grid. Instead of exporting at a lower rate, you use your own energy when needed.

When it makes sense?

Having a battery energy storage system is more worth it if you:

• Have high night-time usage (e.g. aircond, EV charging)
• Generate excess solar during the day
• Use more than 1,500 kWh monthly

Important limitation

The battery does not last overnight for most homes.

Typical residential batteries:

• Can only support a few hours of usage, not the whole night
• May still require grid supply after depletion

It helps reduce bills, but won’t fully replace the grid.

While batteries improve energy independence and efficiency, they come with:

• Higher upfront cost
• Longer payback period compared to solar panels alone

However, under the new Solar ATAP policy, the value of self-consumption increases, making batteries more relevant than before, especially for the right usage profile.

Solaroo’s take

Under the new policy:

Using your own solar energy is more valuable than exporting it. Battery can improve savings, but only with the right usage pattern.

Our final verdict

Worth it if:

• You have high usage and want better energy control

Not necessary if:

• Your daytime usage already matches your solar generation

Sarawak homeowners, listen up, the sun isn’t just for tanning anymore. It’s for reducing your monthly electricity bills! With Sarawak Energy’s Net Energy Metering (NEM) scheme, you can finally turn your roof into a money-saving powerhouse and with Solaroo, you don’t just install solar, you install confidence.

Pekat Energy Sarawak, powered by Solaroo!

Solaroo is proud to bring our residential solar expertise to Sarawak together with our sister company, Pekat Energy Sarawak (PES). As part of the Pekat Group of companies, PES has been serving Sarawak since 2016, leading impactful off-grid initiatives such as SARES and many more across the state. With PES firmly established on their home ground and Solaroo recognised as the group’s specialist in residential solar, we’re teaming up to deliver safe, smart, and reliable solar solutions tailored for Sarawak homeowners. Together, we’re bringing more sunshine, more savings and more energy independence to Sarawak.

What exactly is NEM?

NEM stands for Net Energy Metering, an initiative by Sarawak Energy Berhad (SEB) that rewards you for producing your own solar electricity. Here’s what it is:

• Your solar panels generate electricity during the day.
• All the electricity produced is exported directly to the SEB grid through a separate PV meter.
• Your home continues to use electricity from the grid as usual via your main SEB meter.
• At the end of each month, SEB offsets the electricity you imported from the grid against the electricity your solar system exported, and the net difference is reflected as a bill credit — reducing your monthly SEB bill.

How NEM works in Sarawak

Step 1: You’re eligible if you…

• Are connected to the Sarawak Energy grid

• Have no outstanding bills of more than 2 months or tampering issues

• Install solar PV only (no batteries allowed under NEM)

 Step 2: You apply through Solaroo

Solaroo takes care of the paperwork, the design and all the necessary with SEB.

Step 3: Watch the magic happen

When your solar panels produce energy, it flows back to SEB’s grid, earning you energy credits.

Do however take note, savings are capped at up to 75% of your average electricity bill, based on your last three months’ usage, as required by SEB. This means your PV system is sized to reduce most of your bill, not exceed it — with extra savings only possible during periods of lower usage, such as when you’re away on holiday. 

Now with a bonus: Up to RM12,000 Subsidy

Starting 2026, Sarawak Energy is offering homeowners a hard-to-miss subsidy under the NEM scheme and we are here to help you claim it.

System size (kWac)	Subsidy amount
2.0 – 3.5 kWac	RM 8,000
>3.5 – 6.0 kWac	RM 10,000
>6.0 – 50 kWac	RM 12,000

Eligibility: 

• For landed residential customers only
• One subsidy per account owner
• First-come, first-served, so hurry secure your slot!

With this rebate, your solar payback period gets shorter and your savings skyrocket faster.

Why homeowners are choosing NEM with Solaroo:

Here’s what you get when you go solar the smart way:

• Cut your electricity bills: Generate, use, and earn credits.
• Built with safety at its core: Our microinverter PV systems come with rapid shutdown technology making your home safer for your family.

• Do your part for the planet: Less carbon, more sunshine.
• Hassle-free installation with Solaroo: We handle design, approval and performance monitoring so you don’t have to.

A few things to note

Before you dive in, keep these in mind:

• NEM doesn’t include battery storage (your credits go to SEB, not a battery).
• Unused credits expire after 24 months.
• All SEB applications are submitted by SEB-registered contractor like Pekat Energy Sarawak (PES), working closely with Solaroo on your installation.
• Your roof’s angle and shading can affect how much you generate, but don’t worry, Solaroo does a full assessment for you before installation.
• There is a PV meter deposit connection charges (non refundable) and collateral deposit that you have to pay directly to SEB, which amount ranges from RM1,000 to RM3,500 depends on your house and phase type.

Ready to let the sun pay your bills?

With Sarawak’s endless sunshine, a generous subsidy and our trusted installation, there’s really no reason to keep paying full price for electricity.

You could be exporting power, earning credits and enjoying the glow of free energy from your own rooftop.

So, what are you waiting for, Sarawak? Your roof is ready. Your sun is shining. Reach out to us to make the switch.

Effective 1 January 2026, Solar ATAP (Accelerated Transition Action Programme) becomes Malaysia’s new rooftop solar programme, officially replacing Net Energy Metering (NEM), which ended on 30 June 2025.

If you are wondering:

“Is solar still worth it after NEM?”

“Can I still save money?”

“What’s different under Solar ATAP?”

The short answer is: Yes, solar is still worth it, but ATAP works differently and your PV system sizing matters more than ever.

What is Solar ATAP?

Solar ATAP is designed around self-consumption. That means you use solar energy first for your own home or business and only excess energy is exported to the grid for bill credits.

This shift supports grid stability while still helping Malaysians reduce electricity bills and carbon emissions.

Who can apply?

You can join Solar ATAP if you are:

• An existing TNB customer (home or business)
• A single-owner premise (not multi-tenanted)

• Not under an active NEM contract (If you are, the NEM contract must be terminated first)

How much solar can you install?

Homeowners (Domestic)

• Single-phase: Up to 5 kWac
• Three-phase: Up to 15 kWac

Businesses (Non-Domestic)

• Install up to 100% of your Maximum Demand
• Maximum PV system size: Up to 1 MW

How does the billing work?

You use solar energy for your own consumption first! Any extra energy is exported to the grid and exported energy becomes bill credits!

Credit rates

For homes: Based on your energy charge rate

For businesses: Based on the average System Marginal Price (SMP)

Important to Know: Credits only offset the current month’s bill:

No carry-forward to the next month

No cash payout

Cannot offset SST, KWTBB, AFA, or other non-energy charges

So, oversizing your PV system can lead to wasted potential, which is why proper sizing is critical under ATAP.

Is there a limit to export?

Yes. To ensure grid stability, exports are capped monthly, as per calculated below:

Monthly Export Limit (MAQ):

PV system size (kWac) × 5 sun-hours × number of billing days

Any energy exported beyond this limit will not be credited.

Contract period

The Solar ATAP contract is up to 10 years. After the contract ends:

• You may continue using solar for self-consumption only
• Export and bill credits will no longer apply

Remember, your PV system will still produce electricity for 25+ years! Solar ATAP only defines the export benefit period.

Technical requirements, simplified for you

• PV system must be installed behind your electricity meter
• Certain approvals may be required depending on system size:
  • CCC (Connection Confirmation Check)
  • CAS (Connection Assessment Study)
  • PSS (Power Systems Study)
• Any required grid upgrade costs are borne by the applicant

On battery storage systems (BESS):

Not compulsory

It is allowed

Helps store excess solar instead of exporting

Application process

Solaroo manages all technical assessments and approvals for you. The application includes:

• Apply via the SEDA eATAP portal
• Application fee: RM7.50 per kWac
• PV system must be completed within 18 months after approval
• e-Certificate issued upon completion

Just submit a few key documents to us and we will do the rest!

How do you maximise savings under Solar ATAP?

Solar ATAP rewards smart usage, not oversized systems.

Best practices:

• Size your system based on daytime usage, not roof size
• Shift usage to daytime (AC, machinery, EV charging, water heaters)
• Consider batteries to store excess solar
• Avoid installing large systems just to export power

In simple terms — Who is ATAP best for?

Property owners looking for stable, long-term savings

Businesses operating mainly during daylight hours

Those who want clean energy without speculation

Malaysia’s solar landscape is about to take another exciting step forward with the upcoming Solar ATAP (Accelerated Transition Action Programme) set to launch this December 2025. As anticipation builds, many are wondering how ATAP will differ from the current Net Energy Metering (NEM) scheme, and what it means for Malaysians considering solar energy. 

Let’s break it down.

A quick recap: What is NEM? 

The NEM programme, introduced by the Sustainable Energy Development Authority (SEDA), lets solar users export excess electricity back to the TNB grid in exchange for bill credits.  

It’s been a game changer for both homes and businesses, helping Malaysians cut bills, earn credits and make solar a smart long investment.  

But here’s the catch! NEM quotas are limited, applications are accepted on a first come, first-served basis, once it’s full, you wait!  

Introducing ATAP, Malaysia’s next big leap 

The upcoming Solar ATAP isn’t just another solar policy; it’s the next phase in Malaysia’s green economy vision.  

While official details will be revealed in December, ATAP is expected to: 

• Broader access: Open for residential, commercial and industrials users 

• Simplified processes: Faster, smoother project approvals  

• National impact: Aligned with Malaysia’s 2050 Net-Zero Target 

In short, instead of a fixed one-to-one offset of electricity billing as in NEM, Solar ATAP will probably apply the System Marginal Price (SMP), essentially a floating, market-clearing wholesale rate for exported surplus power. 

 ATAP vs NEM: What to Expect 

ASPECT	NEM	ATAP (EXPECTED)
Main mechanism	Export excess energy to grid for bill credits	Emphasis on self-consumption & energy independence
Quota system	Limited & first-come-first-served	Expected to be broader and more inclusive
Incentive type	1-to-1 offset for surplus energy generated	Excess energy will be netted off based on the System Marginal Price (SMP)
Target users	Mainly residential & commercial	Residential, commercial and industrial
Core focus	Grid contribution	Sustainability, resilience, and local energy use

While NEM rewards you for exporting energy, ATAP could shift the focus toward using your own solar power efficiently, less grid dependency, more energy freedom

This could mean: 

• Storing & using your own clean energy  

• Greater control over your consumption 

• Long term cost stability & sustainability 

• Less reliance on grid export, encouraging users to store and use their own solar power. 

• Greater focus on energy efficiency & sustainability outcomes. 

• Potentially fewer bill credits, but more long-term stability as Malaysia moves toward a greener, self-reliant energy ecosystem. 

The bigger picture: Progress for the Rakyat 

Like any new initiative, ATAP may come with adjustments upon its launch, fewer export benefits or new compliance steps – but its ultimate goal remains clear, to empower Malaysians with clean, affordable, and secure energy. 

Whether you’re a homeowner or a business owner, one thing is certain, the future of solar in Malaysia is bright, and ATAP will be a key part of that journey. 

Stay tuned for more updates this December as Solaroo breaks down the full details of the ATAP programme and how it could benefit you.

Is your solar PV system not generating data or has your solar DB tripped? Don’t worry, this quick guide will help you safely check the issue and get your system back on track.

Part 1: What to do if your solar DB trips

Firstly, let’s get to know the components of your solar DB below:

Now that you know your solar DB’s key components, follow these steps:

1. Safety first:
   • Make sure your hands are dry.
   • Do not touch any exposed wires.
2. Check for these DB scenarios:
   • Scenario 1: If RCCB is DOWN > Push it UP to reset.
   • Scenario 2: If both RCCB & MCB are DOWN > Push MCB UP first, then RCCB UP.

Observe what happens next:

• • If it trips immediately after step 2 above – stop resetting further. Send us a photo/video via WhatsApp at 012-5928010 for further assistance.
  • If both switches stay UP, your solar PV system is working fine. Continue to monitor via the Solaroo app.

If you’ve read recent news about TNB’s electricity tariff updates, you may have come across the newly introduced Time-of-Use (TOU) option. But what exactly is TOU and more importantly, how does it impact your electricity bill, especially if you are already using solar energy?

Let us break it down for you. 

What is Time-of-Use (ToU)? 

Time-of-Use focuses on when you use electricity, rather than how much you use. Unlike the traditional flat-rate tariff where you are charged the same amount per kilowatt-hour (kWh) regardless of when you use it, ToU rewards you for using electricity during off-peak hours, when demand is lower and charges more during peak hours, when demand is high. 

Here’s a quick guide based on TNB’s residential ToU time zones: 

• Monday to Friday

Peak: 2 PM to 10 PM = Higher electricity rates

Off-Peak: 10 PM to 2 PM = Lower electricity rates 

• Saturday, Sunday & Public Holidays*

Off-Peak throughout the day (24 hours) = Lower electricity rates 

Note: Public holidays are the following 15 days including New Year’s Day, the first and second days of Chinese New Year, the first and second days of Hari Raya Aidilfitri, Labour Day, Wesak Day, the Yang di-Pertuan Agong’s Birthday, Hari Raya Aidiladha, Awal Muharram, Independence Day, Malaysia Day, Maulidur Rasul, Deepavali Day and Christmas Day.  

Refer to the table below for a comparison of costs between the standard tariff and the Time-of-Use (ToU) tariff: 

Monthly usage	Off-peak rate (ToU tariff)	Peak rate (ToU tariff)	Standard rate (Standard tariff)
1,500kWh and below	24.43 sen/kWh	28.52 sen/kWh	27.03 sen/kWh
More than 1,500kWh	34.43 sen/kWh	38.52 sen/kWh	37.03 sen/kWh

 

Who benefits MOST from ToU? 

ToU is a game-changer, if you can adjust your usage habits. 

1. You’ll save money if you can shift most of your heavy energy usage (like laundry, air conditioning, EV charging, and water heating) to off-peak hours, especially between 10 PM to 2 PM (next day), or use electricity mostly on weekends.
2. You might end up paying more than a flat-rate tariff if your household’s power consumption happens mainly during 2 PM to 10 PM on weekdays, which falls within the expensive peak period.
    

In short, the ToU tariff is only beneficial if you shift most of your electricity usage to off-peak hours — meaning you’ll need to adjust your usage habits to see real savings. 

 

What if you have solar + ToU (under NEM Rakyat)? 

If you’re a Solaroo customer who have installed a solar PV system under NEM Rakyat and opted for the ToU tariff, you’re in a great position to maximise your energy savings. 

Here’s how the combo works for you: 

• During the day, your solar PV system generates power and reduces your grid dependency, especially during expensive peak hours. 

• Just to recap, under the solar NEM program, your home will use the solar energy you generate first, and only the excess will be exported back to the grid.
• Excess energy is exported back to the grid and offset under NEM’s 1-to-1 credit scheme. 
• The excess energy is also credited based on the time it’s exported. Peak rates apply for exports between 2pm–6pm on weekdays, while weekend exports are credited at off-peak rates.

• By using ToU strategically, you can optimise when you pull power from the grid, for instance during cheaper off-peak hours and rely on your solar energy during peak times. 

In short, the combination of Solar Energy + ToU lets you manage your energy smarter and get more out of your solar investment. 

 

Are there any extra fees? 

When you opt for the TOU tariff, a one-time RM10 stamp duty is required as part of the agreement.

There’s also a monthly Retail Charge of RM10, but this fee is waived if your usage stays at 600 kWh or below. In this low-usage tier, you’re also exempt from the Automatic Fuel Adjustment (AFA) charge.

Additionally, households consuming up to 1,000 kWh per month remain eligible for the Energy Efficiency Incentive, just like those on the standard tariff. 

 

Final thoughts 

Just a note that ToU isn’t for everyone, but with the right setup and some thoughtful changes in your usage patterns, it can lead to long-term savings.  

If you’re already solar-powered or considering it, talk to Solaroo about how ToU fits into your energy goals. We’ll help you design a PV system that works best for you and your family’s lifestyle.  

Smarter energy choices start with knowledge and Solaroo is here to help you take charge.
