Question 1

How is SESCo NEM different from TNB NEM in Peninsular Malaysia?

Accepted Answer

SESCo (Sarawak Energy Berhad) runs its own Net Energy Metering programme separate from TNB. Under NEM Sarawak, excess solar energy you generate is exported to the SESCo grid and credited against your electricity consumption at a 1:1 offset rate. The application process, grid connection timeline, and tariff bands differ from TNB NEM — Trexon handles all SESCo paperwork and coordination on your behalf.

Question 2

Does Sarawak get more sunlight than Peninsular Malaysia?

Accepted Answer

Yes. Sarawak receives average solar irradiance of 4.8–5.2 kWh/m²/day, which is 10–15% higher than many locations in Peninsular Malaysia. Kuching, Miri, Sibu, Bintulu, and Kota Samarahan all have excellent solar resources. This means your solar system in Sarawak generates more energy per kWp installed, resulting in shorter payback periods and higher lifetime savings compared to equivalent systems in KL or Selangor.

Question 3

What size solar system does a Sarawak home need?

Accepted Answer

For a typical Sarawak household with a SESCo bill of RM 200–400/month, a 5–9 kWp system is usually the right size. For households with RM 600–800/month bills, a 10–14 kWp system is recommended. We size your system based on your 12-month SESCo billing history and roof area to maximise NEM offset without over-generating.

Question 4

How long does SESCo NEM approval take in Sarawak?

Accepted Answer

The SESCo NEM application and grid connection process typically takes 4–6 weeks for residential systems. This includes the NEM application submission, site inspection by SESCo, approval, installation, and final meter commissioning. Trexon manages the entire SESCo submission process — you just sign the forms and wait for commissioning day.

Question 5

Do SESCo NEM credits expire like TNB Solar ATAP credits?

Accepted Answer

No. SESCo NEM credits never expire — this is a major advantage over Peninsular Malaysia's TNB Solar ATAP scheme where accumulated credits expire after 12 months. In Sarawak, when your solar panels generate more electricity than you use, the excess is credited to your SESCo account and those credits roll over indefinitely. They can be used in any future billing cycle.
