Commercial Solar Panel Installation in Malaysia — 2026 Complete Guide
Malaysia's commercial electricity tariffs make solar one of the highest-ROI investments available to businesses today. The TNB commercial tariff C1 is 43.60 sen/kWh for low-voltage users and C2 is 38.00 sen/kWh for medium-voltage users. On top of energy charges, industrial businesses pay a maximum demand (MD) charge ranging from RM 30.30/kW (C1 low voltage) to RM 89.27/kW (E2 medium voltage peak/off-peak) — which solar, combined with battery storage, can reduce by 20–40%.
A typical 100 kWp commercial rooftop system produces approximately 120,000–140,000 kWh annually in Malaysia's equatorial climate. At C1 tariff rates, this translates to RM 52,000–61,000 in annual electricity savings. With fully installed system costs of RM 350,000–450,000, the payback period is 4–6 years before GITA — and as short as 2.5–4 years after claiming the 60% Green Investment Tax Allowance.
TNB Commercial Tariff Rates and Solar Savings (2026)
Understanding your TNB tariff category is the first step in sizing your commercial solar system. The key commercial tariffs in Malaysia are:
- Tariff C1 (Low Voltage Commercial): 43.60 sen/kWh — applicable to offices, retail, restaurants, clinics, and small factories below 1 MW demand
- Tariff C2 (Medium Voltage Commercial): 38.00 sen/kWh — applicable to medium commercial and industrial buildings above 1 MW
- Tariff E1/E2 (Industrial): Includes a maximum demand charge of RM 45.10/kW (E1 general MV) to RM 89.27/kW (E2 peak/off-peak MV) per month — solar plus battery targets this component directly
Commercial solar generation peaks between 8am–5pm — exactly when most businesses consume the most electricity. This alignment maximises self-consumption and delivers the highest tariff offset. Under Solar ATAP (NEM 3.0, effective January 2026), any surplus generation is exported to the grid at the System Marginal Price (SMP), but self-consumption at full tariff value is where the primary savings are achieved. Proper system sizing to match your load profile is therefore critical.
GITA 60% Green Investment Tax Allowance (Deadline: December 2026)
The Green Investment Tax Allowance (GITA) is the most powerful financial incentive available to Malaysian businesses investing in solar. Companies can claim 60% of qualifying capital expenditure as a tax allowance against statutory income for a period of 3 years. For a RM 500,000 solar installation, the GITA saves approximately RM 72,000 in corporate tax (at 24% tax rate) — effectively reducing the net investment to RM 428,000 and shortening the payback period by 1–2 years.
The GITA deadline is December 31, 2026. Applications must be submitted through MGTC (Malaysian Green Technology Corporation) before this date. Trexon handles the full GITA application process as part of our commercial solar service — from MyHIJAU equipment certification to MIDA statutory income offset calculations.
Commercial Solar Financing in Malaysia
Malaysian businesses have four main paths to fund commercial solar installations:
- Green bank loans from Maybank, CIMB, Public Bank, and RHB at 3.5–5.0% p.a. with tenures up to 10 years. Best for businesses seeking full ownership and maximum GITA benefit.
- Power Purchase Agreements (PPA) — zero CAPEX, immediate savings. A third-party provider owns the system; you pay only for electricity at 15–30% below TNB rates.
- Hire purchase with fixed monthly instalments over 5–7 years. Own the system at the end of the term.
- Cash purchase with GITA — highest long-term ROI for businesses with strong cash flow and corporate tax obligations.

Frequently Asked Questions
Common questions from Malaysian businesses considering commercial solar
How much does commercial solar cost in Malaysia?
Commercial solar panel installation in Malaysia costs RM 35,000–120,000 for small 10–30 kWp systems (SME offices, clinics, restaurants), RM 120,000–400,000 for mid-size 30–100 kWp systems (factories, hotels, schools), and RM 400,000–1,800,000 for large 100–500 kWp commercial installations. Prices include equipment, mounting, inverter, cabling, TNB application, and commissioning. The GITA 60% tax allowance significantly reduces the effective cost.
What is the ROI for commercial solar in Malaysia?
The typical ROI for commercial solar in Malaysia is 3–5 years. A 100 kWp system saves approximately RM 8,000–10,000 per month at current C1 TNB tariff rates (43.60 sen/kWh), generating RM 2.4 million in savings over 25 years on an investment of RM 350,000–450,000. With the GITA 60% tax allowance, effective payback shortens to 2.5–4 years for qualifying companies.
Can my business claim the GITA tax deduction for solar?
Yes. Malaysian businesses investing in solar energy are eligible for GITA (Green Investment Tax Allowance) — a 60% allowance on qualifying capital expenditure that offsets your statutory business income. For a RM 500,000 solar installation, GITA can save approximately RM 72,000 in corporate tax. The deadline is December 31, 2026. Trexon handles all GITA paperwork including MGTC application and MyHIJAU certification as part of our commercial solar service.
What size solar system does my business need?
Sizing depends on your TNB bill, operating hours, and roof area. A monthly bill of RM 3,000–8,000 typically needs 10–30 kWp; RM 8,000–30,000 needs 30–100 kWp; RM 30,000–200,000 needs 100–500 kWp. Our free commercial energy audit analyses your TNB bill and roof to design the optimal system for maximum ROI under Solar ATAP rules.
Is PPA available for commercial buildings in Malaysia?
Yes. Under a Power Purchase Agreement (PPA), Trexon installs and owns the solar system at zero upfront cost. You pay only for the electricity consumed at 15–30% below TNB rates — immediate savings with no capital expenditure. PPA terms run 10–20 years, with ownership transfer options available at the end of the agreement.
What TNB tariff applies to commercial solar savings?
Most commercial businesses in Malaysia are on TNB tariff C1 (43.60 sen/kWh) or C2 (38.00 sen/kWh). Under Solar ATAP (effective January 2026), solar offsets your consumption at full tariff value during business hours, delivering 30–50% bill reductions. Maximum demand charges under E1/E2 tariffs can also be reduced 20–40% with solar plus battery storage.

Solar ATAP 2026: The New Framework for Malaysian Businesses
Solar ATAP replaces the previous NEM 3.0 scheme as the primary commercial solar export programme in Malaysia. Here is what every business owner needs to know.
How Bill Credits Work
Tariff C1 Users (43.60 sen/kWh)
Low-voltage commercial buildings — offices, retail, restaurants, clinics. Every unit of solar consumed on-site offsets your bill at the full 43.60 sen/kWh rate.
Tariff C2 Users (38.00 sen/kWh)
Medium-voltage commercial and industrial buildings above 1 MW demand. Self-consumed solar offsets at 38.00 sen/kWh — still a substantial saving at scale.
Key Differences from NEM 3.0
Self-Consumption Priority
Solar ATAP prioritises maximising on-site consumption. System sizing should target 80–90% self-consumption to extract maximum tariff value.
Export at Displaced Cost Rate
Surplus electricity exported to the grid earns credit at the System Marginal Price (SMP) — lower than the full tariff. Oversizing your system is therefore suboptimal under ATAP.
Quota Allocation for Commercial Buildings
SEDA allocates Solar ATAP quota by state and sector. Commercial applicants should apply early — quota is released in tranches and popular states fill quickly.

Three financing structures — compared side by side so you can choose the right model for your business.
| Criteria | PPA | Solar Lease | Outright Purchase |
|---|---|---|---|
| Upfront Cost | RM 0 | RM 0 | RM 35K – 1.8M |
| Monthly Payment | 15–30% below TNB rate | Fixed monthly instalment | RM 0 after payback period |
| System Ownership | Provider owns system | Transfers to you at end | You own from day 1 |
| Contract Term | 10–20 years | 7–15 years | None |
| Tax Benefits | OpEx deduction (monthly payments) | OpEx deduction (monthly payments) | GITA 60% + Capital Allowance (CA) |
| Best For | Cash-constrained businesses needing immediate savings | Businesses wanting eventual ownership without large capex | Profitable companies maximising long-term ROI + tax benefits |
Pelaburan Solar Komersial
Pelaburan Solar Komersial: Kurangkan Kos Operasi Perniagaan Anda
