Solar Panel Installation Cost & Solar ATAP ROI Malaysia 2026
New home solar in Malaysia no longer runs under NEM 3.0. Since 1 January 2026 applications go through Solar ATAP, where solar you use yourself cuts your full TNB rate, but exported units earn credit only at the energy charge (27.03 sen/kWh for homes using up to 1,500 kWh a month), and unused credit is forfeited monthly. Paybacks are therefore longer than older NEM-era quotes claim.
This guide replaces our earlier NEM 3.0 version. It explains what changed, how to size a system under the new caps, how to work out your own savings line by line, and what to check before you sign with an installer. It is written for landed homeowners; condo owners should read the strata section near the end.
What Changed: NEM 3.0 vs Solar ATAP
The Energy Commission (Suruhanjaya Tenaga, ST) issued the Guidelines for Solar Accelerated Transition Action Programme (Solar ATAP) on 30 December 2025, and the programme opened to applications on 1 January 2026, administered by SEDA (Energy Commission guidelines and SEDA Solar ATAP portal, checked 5 Oct 2026). Solar ATAP replaces Net Energy Metering (NEM 3.0) for new rooftop systems.
| Feature | NEM 3.0 (closed) | Solar ATAP (2026) |
|---|---|---|
| Export credit for homes | 1:1 offset against imported kWh | Energy charge component only (27.03 sen/kWh up to 1,500 kWh) |
| Unused credit | Offset against imports | Forfeited each billing period |
| Max size, single-phase home | Lower single-phase limit | 5 kW |
| Max size, three-phase home | 12.5 kW | 15 kW |
| National quota | Fixed MW quota, waiting lists | No fixed quota announced |
| Contract term | Per NEM agreement | Up to 10 years from commencement |

The single biggest change for your wallet is the export rate. Under NEM 3.0, a kWh you exported at noon cancelled a kWh you imported at night, so it was worth your full retail rate. Under Solar ATAP, that exported kWh is worth only the energy charge, which is roughly 60% of what you pay per imported kWh once capacity and network charges are added. Self-consumption is now where the money is.
How a 2026 TNB Domestic Bill Is Built
Since 1 July 2025, TNB domestic bills are split into separate components (TNB tariff schedule from 1 July 2025, checked 5 Oct 2026):
| Component | Rate (domestic) | Does solar reduce it? |
|---|---|---|
| Energy charge | 27.03 sen/kWh (≤1,500 kWh/month); 37.03 sen/kWh above | Yes: self-consumption and export credits |
| Capacity charge | 4.55 sen/kWh | Yes, for self-consumed kWh only |
| Network charge | 12.85 sen/kWh | Yes, for self-consumed kWh only |
| Retail charge | RM10/month (waived at ≤600 kWh) | Only if usage falls to the waiver level |
| AFA (fuel adjustment) | Set monthly by ST, can be a rebate or surcharge | Moves with imported kWh |
So every kWh your panels feed straight into your own appliances saves about 44.43 sen (27.03 + 4.55 + 12.85) before AFA, tax and rebates, while every kWh exported earns a 27.03 sen credit. The Energy Efficiency Incentive rebate for lower-use homes, the 1.6% KWTBB levy and the 8% service tax on domestic usage above 600 kWh also move your final bill; we leave them out of the worked example below to keep the arithmetic readable.
System Size and Cost in 2026
The Solar ATAP caps (5 kW single-phase, 15 kW three-phase for homes, per the ST guidelines) apply to the inverter/AC capacity. Many installers pair a 5 kW inverter with slightly more panel (DC) capacity. Typical 2026 turnkey quotes we see quoted publicly by installers sit in these ranges, but prices move with panel and inverter brand, roof type and scaffolding needs, so treat them as starting points for your own quotes rather than fixed prices:
| Typical home | Supply | Indicative system | Indicative turnkey cost |
|---|---|---|---|
| Single-storey terrace, bill RM150–300 | Single-phase | 4–6 kWp panels, 5 kW inverter | RM15,000 – RM22,000 |
| Double-storey terrace, bill RM300–600 | Single- or three-phase | 6–10 kWp | RM20,000 – RM32,000 |
| Semi-D / bungalow, bill RM600+ | Three-phase | 10–15 kW | RM30,000 – RM48,000 |
If your house is single-phase and you want more than 5 kW, TNB must approve a supply upgrade to three-phase first, which adds cost and time. Ask your installer to quote with and without that upgrade.
What a Turnkey Package Should Include
Compare quotes line by line. A complete residential package covers four things:
- Solar PV panels: monocrystalline panels from an established manufacturer, with a long-term linear performance warranty.
- Inverter: converts the panels' DC output to AC for your home, usually with a mobile app for monitoring generation.
- Bi-directional TNB meter: installed by TNB to record both the electricity you import and the solar you export.
- Roof mounting structure: aluminium rails rated for wind load and matched to your roof type.
Worked Example: 5 kW System on a Selangor Double-Storey Terrace
Assume a family in a double-storey terrace in Shah Alam uses 900 kWh a month. They install a 5 kW inverter with about 6 kWp of panels.
- Monthly solar generation: about 660 kWh (assumes roughly 110 kWh per kWp per month, a common planning figure for Peninsular Malaysia; your installer's site-specific yield estimate replaces this).
- Used directly in the home during the day: 300 kWh.
- Exported to the grid: 360 kWh.
- Still imported from TNB: 900 − 300 = 600 kWh.
Savings line by line:
- Self-consumption: 300 kWh × 44.43 sen = RM133.29
- Export credit: 360 kWh × 27.03 sen = RM97.31, offset against the energy charge on the 600 kWh still imported (600 × 27.03 sen = RM162.18), so the full credit is used and nothing is forfeited.
- Monthly saving: RM133.29 + RM97.31 = about RM230.60
- Annual saving: RM230.60 × 12 = about RM2,767
Payback on a RM22,000 turnkey price:
- RM22,000 ÷ RM2,767 = about 7.9 years
That is roughly double the four-to-five-year paybacks advertised in the NEM 3.0 era. Now change one thing: if the household shifts laundry, dishwasher and air-conditioning pre-cooling into daylight hours and self-consumes 450 kWh instead of 300 kWh (exporting 210 kWh), the saving rises to about RM256.70 a month and the payback falls to about 7.1 years. Behaviour matters more under Solar ATAP than under NEM.
The forfeiture trap: if a small household exports more credit than its energy charge in a month, the excess disappears. Oversizing a system for a low-use home is the easiest way to lose money on solar in 2026.
Choosing an Installer and Financing
- Use a SEDA-registered PV service provider. Solar ATAP applications are submitted through SEDA, and SEDA publishes the list of registered installers (SEDA Solar ATAP portal, checked 5 Oct 2026). Ask for the registration number and check it yourself.
- Get a site-specific yield estimate. Insist on a generation estimate based on your roof pitch, orientation and shading, not a generic table.
- Read the warranty split. Panels usually carry a long performance warranty; inverters usually carry a much shorter one and are the part most likely to need replacing within the system's life. Budget for an inverter replacement in your payback math.
- Check who handles the paperwork. A good installer prepares the SEDA application, the technical assessment and the TNB meter change.
- Financing: Some banks offer green or solar financing and credit-card instalment plans. Compare the total interest cost against your annual saving; a loan at a high effective rate can stretch a seven-year payback well beyond ten.
Roof, Orientation and Strata Considerations
- Orientation: Malaysia sits close to the equator, so the sun is high for most of the year. East- and west-facing roofs still produce well; heavy shading from neighbouring buildings or trees matters more than compass direction.
- Cloud and rain: panels still generate on overcast days from diffuse light, at a fraction of their clear-sky output. A site-specific yield estimate already averages this in, which is why monthly generation is steadier than a single rainy week suggests.
- Roof condition: Fix leaks and replace brittle tiles before panels go up. Removing and refitting panels later costs extra.
- Condos and stratified landed homes: the roof is usually common property managed by the JMB or MC. You will need management approval, and in most high-rises an individual unit cannot install its own rooftop system. Gated landed schemes with strata titles also need management approval before mounting anything on the roof.
Resale: a working system with transferable warranties makes a landed home stand out among neighbouring subsale listings, because the buyer inherits lower electricity bills. Keep the SEDA approval, the installer's handover documents and your generation records to show buyers, and do not assume the system adds its full cost to the sale price.
If you are still choosing a house and solar is part of the plan, landed areas such as Puchong and Shah Alam have large stocks of terraces with usable pitched roofs.
Frequently Asked Questions (FAQ)
Q: Can I still apply for NEM 3.0 in 2026?
No. Solar ATAP replaced NEM 3.0 for new applications from 1 January 2026, under the Energy Commission's Solar ATAP guidelines issued on 30 December 2025. Existing NEM customers generally remain on their original agreement; check yours with TNB.
Q: How much does TNB pay for solar I export under Solar ATAP?
Domestic exports are credited at the energy charge component of your tariff, which is 27.03 sen/kWh for households using up to 1,500 kWh a month. The credit offsets your bill; it is not paid out as cash, and unused credit is forfeited at the end of each billing period.
Q: What is the maximum solar system size for a house under Solar ATAP?
5 kW for single-phase domestic supply and 15 kW for three-phase domestic supply, according to the Energy Commission guidelines. A larger system on a single-phase house requires a TNB supply upgrade first.
Q: What is a realistic payback period for home solar in 2026?
For a typical terrace house, roughly seven to nine years under Solar ATAP, depending on price, how much solar you use directly and your monthly usage. Paybacks of four to five years quoted in older articles were based on NEM 3.0's one-to-one export offset.
Q: Is solar still worth it without NEM?
It can be, if the system is sized to your daytime use. Each self-consumed kWh saves about 44 sen before AFA and taxes, against 27 sen for each exported kWh, so homes that are occupied in the day or run air-conditioning in the afternoon benefit most.
Q: Can I install solar panels on my condo unit?
Usually not individually. The roof is common property, so any installation needs JMB or MC approval, and most high-rises do not permit individual rooftop systems. Some buildings install shared systems to cut common-area electricity costs.
Q: Does a solar system work during a TNB blackout?
A standard grid-tied inverter shuts down during a power cut so it does not feed electricity into lines that TNB crews may be repairing. Backup power needs a hybrid inverter with a battery, which adds significant cost.
Q: How often do solar panels need cleaning in Malaysia?
Regular rain removes most dust. An annual inspection, including a check of the inverter, wiring and roof seals, is a sensible minimum; clean more often if you live near a construction site or busy road.
