How Much Does Commercial Solar Cost in Malaysia? 2026 Complete Price Guide
Quick Answer
Commercial solar installation in Malaysia costs RM150,000–RM1.6M depending on system size. A 50kWp system starts at RM150K, 100kWp at RM300K, and 500kWp at approximately RM1.2M. After GITA 60% tax allowance, effective costs are significantly lower for companies paying corporate tax.
If you are a business owner, CFO, or facilities manager in Malaysia evaluating solar for your commercial or industrial premises, this guide gives you the exact numbers you need — system costs, monthly savings, payback periods, and GITA tax savings — broken down by system size.
Prices here reflect 2026 market rates based on Trexon's active project pipeline. All figures include supply, installation, cabling, inverters, mounting structure, monitoring system, Solar ATAP application (RM 7.50/kW non-refundable fee), and commissioning.

GITA 60% Tax Allowance — How It Works
The Green Investment Tax Allowance (GITA) is the single biggest financial lever for commercial solar buyers in Malaysia. It allows companies to claim a 60% tax allowance on qualifying solar capital expenditure, set off against 70% of statutory income over 5 years.
This is not a rebate or a grant — it reduces your taxable income, which means you pay less corporate tax. For a company paying 24% corporate tax, the effective cash savings are substantial.
GITA Walkthrough: RM300,000 System (100kWp)
GITA deadline: December 31, 2026. MIDA application must be submitted before installation begins.
GITA is approved by MIDA (Malaysian Investment Development Authority) — not LHDN. Your solar installer must be a SEDA-registered RPVSP. Trexon Energy is fully registered and handles all GITA documentation.

PPA vs Outright Purchase: Which Is Better for Your Business?
| Factor | Outright Purchase | PPA (Zero Capex) |
|---|---|---|
| Upfront cost | Full capex required | RM 0 |
| Monthly savings | 100% kept by you | 20–30% discount vs TNB |
| GITA eligibility | Yes | No (investor claims it) |
| System ownership | You own it | Investor-owned |
| Maintenance | Your responsibility | Covered by investor |
| Best payback ROI | Yes (3–5 years) | No (savings shared) |
| Best for | Companies with capex budget + tax appetite | Companies with capex freeze policy |
For most profitable manufacturing and logistics companies, outright purchase with a green bank loan is the highest-ROI option — especially in 2026 before the GITA deadline. PPA is the right choice if your company has a strict no-capex policy or is in an asset-light growth phase.

Financing Options for Malaysian Businesses
1. Green Bank Loans (Cash Flow Positive from Month 1)
Major Malaysian banks offer green financing facilities specifically for solar installations. With the right loan structure, your monthly loan repayment is less than your monthly TNB savings — making you cash flow positive from day one.
- CIMB Green Financing — up to 7-year tenure, competitive rates
- SME Bank Green Tech Facility — subsidized by Bank Negara's HTG scheme
- Maybank Business Solar Loan — up to 80% margin, 5-year tenure
- EXIM Bank Green Financing — suited for export-oriented manufacturers
2. Operating Lease
Similar to a PPA but with fixed monthly payments (not tied to energy generation). The system is returned or purchased at end of lease term. Keeps the asset off your balance sheet.
3. Hire Purchase
Available through solar-specialist financiers. Ownership transfers to you upon final payment. GITA is still claimable under hire purchase, as long as the HP agreement structure qualifies as a capital expenditure under MIDA's guidelines.

Factors That Affect Your Commercial Solar Price
The price tables above are indicative. Your actual quote will vary based on:
- Roof type and condition — Metal deck roofs are easiest. Concrete flat roofs may require additional ballast mounting. Older roofs may need structural assessment.
- System orientation — South-facing maximizes generation in Malaysia. East-west split arrays can improve morning/evening generation but add cost.
- TNB connection point — Distance from the solar array to the main distribution board (MDB) affects cabling cost. Some sites require a new TNB metering panel.
- Shading and obstructions — Rooftop AC units, water tanks, or structural columns require layout optimization. Micro-inverters or power optimizers may be needed.
- Grid connection capacity — TNB must approve NEM connection. Some substations are near capacity and require technical review before approval.
- Location — Projects in Sabah and Sarawak (SESB/SEB grid) follow different NEM rules and have slightly different panel performance due to irradiance differences.
Frequently Asked Questions
How much does a 100kWp commercial solar system cost in Malaysia in 2026?
A 100kWp commercial solar system costs approximately RM280,000–RM320,000 all-in. After the GITA 60% tax allowance, the effective cost to a company at 24% corporate tax rate is reduced by up to RM43,200 over 5 years.
What is the payback period for commercial solar in Malaysia?
Commercial solar payback periods range from 3 to 5 years. Factories and warehouses on MV tariffs (E1/E2) with high electricity consumption achieve payback in 3–4 years. Smaller commercial premises on LV tariffs (C1/C2) typically achieve payback in 4–5 years.
Does GITA apply to rented commercial premises?
Generally, GITA requires the company to own the premises. However, long-term tenancies (5+ years) with explicit landlord written consent may be considered by MIDA on a case-by-case basis.
What is the difference between PPA and outright purchase?
PPA has zero upfront cost — a solar investor installs the system and you buy the electricity at 20–30% below TNB rates. Outright purchase means you own the system and keep 100% of the savings, plus you qualify for GITA. Outright purchase has a higher total ROI; PPA suits companies with strict capital preservation policies.
Can an SME claim GITA for commercial solar?
Yes. SMEs incorporated as Sdn Bhd are eligible for GITA at the same 60% rate. SMEs pay 17% corporate tax on the first RM600K of income, so the absolute tax savings are slightly lower than large companies, but the mechanics are identical.
