Commercial Solar Panel Cost for Factories & Businesses in Malaysia 2026

Commercial solar panel cost Malaysia is one of the most common questions Malaysian homeowners and businesses ask before going solar. This page breaks down commercial solar panel cost Malaysia in plain terms, with guidance from MIDA.

Why Should Businesses Consider Solar?

Factories and businesses operating during daytime hours (peak TNB tariff hours) benefit the most from solar, since their electricity consumption matches peak solar output. This means a much higher bill offset compared to residential homes.

Estimated Cost by Commercial System Size

GITA — Cutting Your Effective Cost by Up to 60%

The Green Investment Tax Allowance (GITA) lets businesses claim 60% of qualifying capital expenditure (for own-consumption systems) as a tax deduction, offsetting up to 70% of statutory income per year. For companies running solar as a business/project (GITA Project), the deduction can go up to 100%.

Applications go through MGTC (for GITA Asset) or MIDA (for GITA Project), and application deadlines can change — confirm the current cut-off date with MGTC/MIDA before making an investment decision.

ROI Period for Businesses

Most commercial systems pay back their cost within 4-7 years, but with GITA, this period can shorten significantly since the tax deduction reduces the effective cost from year one.

Best-Fit Business Segments

– Factories & manufacturing

Frequently Asked Questions

1. What system size suits a medium-sized factory?
It depends on monthly consumption (kWh), but a medium factory typically needs 100kW-300kW. An energy audit is needed for exact sizing.

2. Is GITA automatically granted after installing solar?
No — you must apply and receive approval from MGTC/MIDA before or after installation (within the set timeframe), it’s not automatic.

3. What’s the difference between GITA Asset and GITA Project?
GITA Asset (60%) is for businesses installing solar for their own use. GITA Project (100%) is for companies running a solar project as a business (e.g. a solar energy seller).

4. Can businesses install solar with no upfront capital?
Yes, through a PPA (Power Purchase Agreement) scheme where the solar provider installs and owns the system, and the business only pays for the energy used at a rate lower than TNB’s.

5. How long does TNB grid connection approval take for commercial systems?
For systems over 72kW, a Connection Assessment Study (CAS) is required first — this process can take a few weeks to months depending on complexity.

6. Will the GITA incentive expire?
Based on current guidelines, there’s an overall cut-off date at the end of 2026 for some categories — confirm with MGTC/MIDA since dates can be extended or renewed.

7. Is maintenance cost higher for commercial systems than residential?
Yes, in absolute terms — since the system size is larger — but the per-kW maintenance cost is usually comparable or lower due to scale.

8. Can solar reduce maximum demand charges for businesses?
Yes, especially with battery storage systems (peak shaving) — this can lower the high maximum demand charge on commercial TNB bills.
