Malaysian factories and manufacturing plants face TNB electricity bills that represent 15–25% of operating costs. Industrial solar installations between 100 kWp and 5 MWp consistently deliver 30–40% reductions in energy expenditure while qualifying for the Green Investment Tax Allowance (GITA) — a 60% tax allowance on qualifying capital expenditure with a deadline of December 2026. Trexon Energy engineers and commissions large-scale solar PV systems for heavy industry across Peninsular Malaysia, with zero-upfront ESCO and PPA financing structures available.
The Green Investment Tax Allowance (GITA) allows Malaysian companies that invest in approved green technology assets — including solar PV systems — to claim a 60% investment tax allowance on qualifying capital expenditure. This allowance can be offset against 70% of statutory income in the year of assessment, substantially reducing the effective cost of a solar installation.
For a 500 kWp system with a capital cost of RM 1.75 million, a GITA claim of RM 1.05 million (60%) reduces taxable income by up to RM 735,000 at 70% offset. At a corporate tax rate of 24%, this translates to a real cash saving of approximately RM 176,400 in the year of commissioning.
GITA applications are processed through the Malaysian Investment Development Authority (MIDA). Trexon coordinates the full MIDA submission on your behalf. The current GITA incentive window closes in December 2026 — factories that miss this deadline revert to standard capital allowances, which are less favourable.

We typically recommend 100 kWp+ for industrial applications. Smaller factories can still benefit from 50–100 kWp systems. Contact us for assessment.
GITA provides tax relief on green investments, including solar PV systems. You can claim deductions on installation costs. We can coordinate with your tax advisor.
Yes! Our systems integrate seamlessly with existing production equipment. We conduct detailed compatibility analysis during site assessment.
Energy Service Companies (ESCO) or Power Purchase Agreements (PPA) allow zero upfront cost, with payments from energy savings. We can arrange both structures.
Peak shaving with battery storage helps manage demand charges during peak hours. Combined with solar, this can reduce bills by 30–40%.

Common questions from industrial and commercial facility managers
We typically recommend a minimum of 100kWp for industrial facilities to achieve meaningful cost savings. However, we assess each facility individually based on roof space, energy consumption patterns, and financial goals. Larger installations (500kWp+) offer better economies of scale.
Peak shaving uses solar power generation during high-demand periods to reduce your maximum demand (MD) charges. When your factory draws the most power, our solar system supplements grid electricity, effectively lowering your peak consumption readings. This can reduce MD charges by 20-30%, which often represent a significant portion of industrial electricity bills.
The Green Investment Tax Allowance (GITA) allows qualifying green technology investments including solar PV systems to claim 100% of qualifying capital expenditure against statutory income. This significantly reduces the effective cost of your solar installation and improves ROI. Our team handles all MIDA application processes.
Yes, through our ESCO (Energy Service Company) or PPA (Power Purchase Agreement) models, you can have a solar system installed with zero upfront cost. You simply pay for the electricity generated at a fixed rate that is lower than TNB tariffs, guaranteeing immediate savings from day one.
We design our installation schedules around your production requirements. Most rooftop work is done during weekends or scheduled maintenance periods. Ground-mount systems have zero impact on production. Our experienced teams complete most industrial installations within 4-8 weeks depending on system size.
Solar installation provides quantifiable carbon reduction metrics for your sustainability reports. We provide detailed CO2 emission reduction certificates and assist with CDP reporting, GRI standards compliance, and RE100 commitments. Many multinational clients require suppliers to demonstrate renewable energy adoption.
