GITA capital allowance eligibility (subject to approval)
Malaysia's Green Investment Tax Allowance (GITA) offers a capital allowance equal to 60% of qualifying solar capital expenditure, offset against up to 70% of statutory income in the year of assessment, for expenditure incurred before 31 December 2026. Indicative only. Subject to MGTC/MIDA approval, applicable tax law and confirmation by the customer’s licensed tax adviser. Official GITA Asset window ends 31 December 2026.
Low-voltage industrial (Tariff D) customers pay a combined RM 0.4868/kWh (energy, capacity and network charges) plus the 1.6% KWTBB levy — TNB Commercial & Industrial Pricing & Tariffs, schedule stamped 2025-01-01. Medium- and high-voltage accounts add a maximum-demand charge read from your bill. Solar generation offsets the energy component directly, for as long as the system runs.
Qualifying solar capital expenditure incurred before 31 December 2026 may claim a capital allowance equal to 60% of qualifying capex, offset against up to 70% of statutory income in the year of assessment. Indicative only. Subject to MGTC/MIDA approval, applicable tax law and confirmation by the customer’s licensed tax adviser. Official GITA Asset window ends 31 December 2026.

Not a customer case study. Every figure below is arithmetic on Trexon's proposal-engine generation assumption (94.6 kWh per kWp per month) and this vertical's own stated typical system-size band, applied at the low-voltage industrial (Tariff D) energy rate. Your facility's actual tariff class, load profile and savings depend on a site assessment of your TNB bill.
| Modelled system size | 120 kWp — mid-point of this vertical's typical band |
| Load profile assumption | two-shift operation, 80% typical self-consumption |
| Modelled monthly generation | 11,354 kWh |
| Modelled self-consumed energy | 9,083 kWh/month |
| Modelled monthly bill offset | RM 4K at the Low Voltage Industrial (Tariff D) rate |
| Modelled annual bill offset | RM 53K |
A system this size may also qualify for the Green Investment Tax Allowance (GITA): a capital allowance equal to 60% of qualifying solar capital expenditure, offset against up to 70% of statutory income in the year of assessment, for expenditure incurred before 31 December 2026.
