The 2026 Guide to Commercial Solar: Zero Capex & GITA Tax Allowances

For Malaysian businesses—particularly manufacturing facilities, warehouses, and large commercial solar installation candidates—electricity is one of the highest operating expenses. With TNB's Maximum Demand (MD) charges sitting at a hefty RM 89.27/kW (for MV/HV), optimizing energy costs is no longer just an ESG initiative; it is a bottom-line necessity.

The good news? In 2026, transitioning your facility to solar power does not require depleting your cash reserves.

1. Zero Capex Solar (Power Purchase Agreements)

Also known as the "Zero Upfront Cost" model, a Corporate Power Purchase Agreement (PPA) allows your business to install a massive solar array on your factory roof without paying a single Ringgit upfront.

How a PPA Works:

• The Investor Pays: A solar investor (or Trexon Energy) covers 100% of the cost for the solar panels, inverters, and installation.
• You Buy the Power: You agree to purchase the electricity generated by the solar system at a significantly discounted rate compared to TNB's tariff.
• Guaranteed Savings: Your PPA tariff is typically 20% to 30% cheaper than TNB. From day one, your total energy bill drops.
• Zero Maintenance: The investor is responsible for the operations, maintenance, and insurance of the system for the duration of the contract (usually 15-20 years).

Best For: Companies with high energy consumption but strict capital preservation policies, or companies who do not want the burden of maintaining solar infrastructure.

2. Outright Purchase & The GITA Tax Allowance

If your company has cash reserves or access to a green bank loan, purchasing the solar system outright yields the highest possible Return on Investment (ROI)—often paying for itself in under 3.5 years.

This rapid payback is heavily subsidized by the Malaysian Government's Green Investment Tax Allowance (GITA).

What is GITA?

GITA allows companies to claim an investment tax allowance of 60% of qualifying capital expenditure incurred on a green technology project. This allowance can be offset against 70% of statutory income in the year of assessment. Unutilized allowances can be carried forward until fully absorbed.

When you combine the RM 360,000 tax savings with the Capital Allowance (CA) depreciation write-offs and the massive monthly reduction in your TNB bill, an outright purchase becomes incredibly lucrative.

3. Green Bank Loans

If you want the high ROI of an outright purchase but lack the initial capital, Malaysian banks (like CIMB, SME Bank, and Maybank) offer specialized Green Financing facilities.

• Low Interest: Often subsidized by schemes like the High Tech & Green Facility (HTG) by Bank Negara Malaysia.
• Cash Flow Positive: By structuring the loan correctly, the monthly repayment to the bank is less than the amount you save on your TNB bill. Your business is cash-flow positive from month one.
