- • GITA 60% tax allowance applies for Sarawak factories and commercial properties.
- • works for Sarawak residents — effectively zero interest financing.
Sarawak — the Land of the Hornbills — is one of Malaysia's best-kept secrets for solar energy. With exceptional solar irradiance, a unique electricity grid (Sarawak Energy Berhad / SEB), and competitive electricity rates, going solar in Kuching, Miri, Sibu, or Bintulu in 2026 delivers outstanding returns.
This guide covers everything you need to know: why Sarawak's conditions are uniquely suited to solar, the critical differences between NEM Sarawak and Peninsula's Solar ATAP scheme, 2026 pricing data, available financing options, and the top solar installers serving Kuching, Miri, Sibu, and Bintulu.
Why Sarawak is PERFECT for Solar
Most Malaysians assume Kuala Lumpur or Johor Bahru get the most sun. In reality, Kuching and Miri consistently outperform Peninsula cities in solar irradiance measurements:
Solar Irradiance Comparison — Malaysia 2026
| City | Peak Sun Hours/Day | Grid | Rate (Residential) |
|---|---|---|---|
| Kuching, Sarawak | 5.8 hrs | SEB | RM0.432/kWh |
| Miri, Sarawak | 5.7 hrs | SEB | RM0.432/kWh |
| Johor Bahru | 5.6 hrs | TNB | RM0.571/kWh |
| Kuala Lumpur | 5.1 hrs | TNB | RM0.571/kWh |
| Penang | 5.0 hrs | TNB | RM0.571/kWh |

The 5.8 sun hours/day in Kuching means a standard 8kWp system generates approximately 1,300–1,500 kWh per month — significantly more than the same system in Kuala Lumpur (1,050–1,200 kWh). This directly translates to higher monthly savings and a faster payback period.
NEM Sarawak vs Peninsula Solar ATAP — Key Differences
One of the most critical things to understand about solar in Sarawak is that it operates under a completely different grid and regulatory framework from Peninsular Malaysia. Here is what you need to know:
| Factor | NEM Sarawak (SEB) | Solar ATAP (TNB Peninsula) |
|---|---|---|
| Grid Operator | Sarawak Energy Berhad (SEB) | Tenaga Nasional Berhad (TNB) |
| Regulator | Suruhanjaya Tenaga (Sarawak) | SEDA / Suruhanjaya Tenaga |
| Export Credit | SEB tariff rate credit | Energy Charge credit, forfeited monthly |
| Installer Requirement | SEB-approved + SEDA RPVSP | SEDA RPVSP only |
| Application Process | Through SEB directly | Through TNB myNEM portal |
Key warning: If you hire a Peninsula-based installer who is only TNB-approved but NOT SEB-approved, your NEM Sarawak application will be rejected. Always verify your installer has explicit SEB credentials for Sarawak installations.

Top Cities We Serve in Sarawak
Kuching
Sarawak's capital and largest city. Most of our Sarawak installations are in Kuching, particularly in Petra Jaya, Kota Samarahan, Batu Kawa, and Padawan areas. Typical residential system: 8–10 kWp. We have a dedicated team covering Kuching and can complete installations within 48 hours of SEB approval.
Miri
Sarawak's second city and Malaysia's oil capital. Miri receives an excellent 5.7 peak sun hours per day. Popular with both residential homeowners and SME commercial businesses in the energy sector. Our team covers all Miri divisions including Piasau, Permyjaya, and Marina.
Sibu
The commercial hub of Central Sarawak. Sibu is particularly strong for commercial solar installations — shophouses, factories, and warehouses along the Rajang River corridor. GITA tax incentive is especially relevant for Sibu's manufacturing base.
Bintulu
Home to Malaysia's LNG complex and heavy industry. Large-scale commercial and industrial solar installations (100 kWp and above) with excellent ROI due to high energy consumption. We serve all industrial parks in Bintulu including BIDA, Tanjung Kidurong, and Kemena.
Kota Samarahan
University town adjacent to Kuching with rapidly growing residential areas. Popular for 6–8 kWp residential systems among UNIMAS and government staff housing.
GITA Tax Incentive for Sarawak Businesses
The Green Investment Tax Allowance (GITA) is one of the most powerful incentives available to Sarawak businesses in 2026. Under GITA, companies can claim a 60% investment tax allowance on qualifying solar capital expenditure against their statutory income.
For a factory in Kuching that invests RM300,000 in a 150kWp solar system, the GITA allowance is RM180,000 — translating to a tax saving of RM30,600 to RM43,200 depending on the company's tax rate. Combined with energy bill savings, the effective ROI can be remarkable.
For rural properties in interior Sarawak — including longhouses, plantation estates, and remote industrial sites — where SEB grid access is limited or unavailable, our off-grid solar for Sabah & Sarawak solutions provide full energy independence with battery backup.
How to Finance Your Sarawak Solar System
Option 1: Green Bank Loan (From 3.5% p.a.)
Note on EPF (KWSP): Solar panels are not currently on KWSP's approved home improvement withdrawal list, so Account 2 withdrawals cannot be used to pay for a residential solar installation. Instead, Sarawak residents can apply for a green bank loan from Maybank, CIMB, RHB, Public Bank or BSN — rates from 3.5% p.a. with tenures up to 10 years. Trexon prepares all the paperwork and the bank disburses funds directly to the installer.
Option 2: SEB Green Loan / Islamic Financing
Several banks offer green financing products for solar systems at competitive rates. Bank Islam, Maybank, and Public Bank all have solar-specific loan products. Trexon can assist with documentation for your bank application.
Option 3: Cash / Credit Card Instalment (0% EPP)
For those with sufficient savings or a credit card with instalment plans, 0% easy payment plan (EPP) options of up to 24 months are available through participating banks.
