Why Automotive Parts Needs Solar Now
60% GITA Tax Allowance
Malaysia's Green Investment Tax Allowance (GITA) offers an investment tax 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 verification, applicable tax law and confirmation by the customer’s licensed tax adviser. The system must be commissioned and the GITA Asset application submitted to MGTC by 31 December 2026.
TNB Tariffs Are Structured, Not Flat
Non-Domestic Low Voltage (formerly Tariff D) customers pay a combined RM 0.5068/kWh (energy, capacity and network charges) plus the 1.6% KWTBB levy — TNB Commercial & Industrial Pricing & Tariffs, schedule stamped 2025-07-01. Medium- and high-voltage accounts are on different rates (for example MV General at RM0.2983/kWh energy charge) and add a maximum-demand charge read from your bill, so the RM 0.5068/kWh figure is a low-voltage assumption only. Solar generation offsets the energy component directly, for as long as the system runs.
60% GITA Tax Allowance — Window Closes 31 December 2026
Qualifying solar capital expenditure incurred before 31 December 2026 may claim an investment tax 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 verification, applicable tax law and confirmation by the customer’s licensed tax adviser. The system must be commissioned and the GITA Asset application submitted to MGTC by 31 December 2026.

Illustrative engineering scenario
Modelled example for a automotive parts facility
Not a customer case study. Every figure below is arithmetic on Trexon's yield basis (3.5 peak sun hours, 105 kWh per kWp per month) and this vertical's own stated typical system-size band, applied at the Non-Domestic Low Voltage (formerly 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 | 190 kWp — mid-point of this vertical's typical band |
| Load profile assumption | two-shift operation, 80% assumed self-consumption (best case) |
| Modelled monthly generation | 19,950 kWh |
| Modelled self-consumed energy | 15,960 kWh/month |
| Modelled monthly bill offset | RM 8K at the Non-Domestic Low Voltage rate (RM0.5068/kWh) |
| Modelled annual bill offset | RM 97K |
A system this size may also qualify for the Green Investment Tax Allowance (GITA): an investment tax 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.
