by Ho Chin Kun The Era of “Wait and See” for Solar is Over
As of January 1, 2026, Malaysia’s Solar ATAP (Solar Accelerated Transition Action Programme) has officially replaced NEM 3.0 — and the rules of the game have changed permanently for industrial property owners and tenants across the country.
This isn’t another incremental policy update. It’s a structural shift in how industrial rooftops generate value. And for factory and warehouse owners still sitting on the fence, there is now a very real financial deadline looming.
What Is Solar ATAP and How Is It Different from NEM 3.0?
Solar ATAP replaces the Net Energy Metering (NEM) 3.0 scheme that ran from 2021 to 2025. The key differences for industrial users are significant:
- No quota limits for commercial and industrial users — unlike NEM 3.0 which had a fixed 1,700 MW allocation under NEM NOVA
- System sizing up to 100% of Maximum Demand (capped at 1 MWac) — factories can now offset virtually their entire daytime electricity consumption
- Monthly rollover of export credits at System Marginal Price (SMP) — unused credits no longer expire at month-end
- 10-year contract tenure — after which the system operates strictly for self-consumption
The 2026 GITA Cliff: Why You Cannot Afford to Wait
Here is the most urgent piece of information every industrial property owner in Malaysia needs to know right now:
The Green Investment Tax Allowance (GITA) — which provides a 60% to 100% Investment Tax Allowance (ITA) on qualifying solar and BESS capital expenditure — is currently set to expire on December 31, 2026.
Under GITA, companies can offset the ITA against up to 70% of their statutory income. For a factory spending RM 2 million on a solar + BESS system, this translates to a tax shield worth hundreds of thousands of ringgit — potentially eliminating your entire tax liability for several years.
If your system is not commissioned and approved before December 31, 2026, you lose this incentive entirely. Given that solar projects typically take 3–6 months from design to commissioning, the window to act is now — not in Q4.
The 100% Maximum Demand Rule: What It Means for Your Factory
Under Solar ATAP, industrial consumers can now size their solar PV system up to 100% of their Maximum Demand (MD), subject to a ceiling of 1 MWac.
Maximum Demand refers to the highest electrical load (in kW) your factory draws from TNB during peak hours (8am–10pm, Monday to Friday). For a facility with a 500 kW MD, this means you can install up to 500 kWp of solar panels — enough to power your entire daytime operations from your own roof.
Combined with TNB’s Time-of-Use (TOU) tariff revision effective July 2025 — which replaced traditional MD charges with Capacity and Network Charges — a well-designed Solar ATAP system can dramatically reduce your monthly TNB bill across multiple charge components.
The BESS Factor: Strategic, Not Optional
For solar systems above 72 kWp, Battery Energy Storage Systems (BESS) have become a strategic necessity under Solar ATAP. Here’s why:
- Export rate management: Surplus energy exported to the grid is credited at SMP — a market-based rate that varies. BESS allows you to store excess generation and use it during peak-tariff hours instead of exporting at a lower rate
- Demand charge reduction: BESS can “shave” your peak demand by discharging during your highest-load periods, directly reducing your Capacity and Network Charges
- GITA-eligible: BESS is a qualifying asset under GITA with a 100% ITA — making it one of the most tax-efficient capital expenditures available to Malaysian industrial companies right now
The ROI Math: Your Roof as a Profit Centre
With current 2026 industrial TNB tariffs and Solar ATAP parameters, the financial case for rooftop solar is compelling:
| Parameter | Typical Industrial System |
|---|---|
| System size | 200 kWp – 1,000 kWp |
| Estimated capex | RM 180,000 – RM 900,000 |
| Annual savings (electricity) | RM 50,000 – RM 250,000 |
| Simple payback period | 3.5 – 4.5 years |
| System lifespan | 25 – 30 years |
| Net profit years (post-payback) | 20+ years |
| GITA tax benefit (if applied) | 60% – 100% ITA on capex |
The math is straightforward: a system that pays for itself in under 4 years, protected by a 25-year warranty, with 20+ years of essentially free electricity after that — is not an expense. It is one of the highest-returning capital investments available to an industrial business today.
What Industrial Property Owners and Tenants Should Do Now
Whether you own or lease your industrial premises, the action steps differ slightly:
If You Own Your Factory or Warehouse:
- Commission a Solar ATAP feasibility study immediately — assess your roof condition, MD, and shading factors
- Engage a SEDA-registered solar contractor to submit your ATAP application
- File for GITA with MGTC before commissioning — the application must be approved before the December 31, 2026 deadline
- Evaluate BESS if your system exceeds 72 kWp or your peak demand charges are significant
If You Are a Tenant:
- Negotiate a solar rights clause in your tenancy agreement — some landlords will co-invest in a system with shared savings arrangements
- Ask your landlord about Solar ATAP eligibility for the building — a solar-equipped industrial unit commands higher rental value and lower operating costs
- Consider properties that already have solar installed — this is increasingly a factor in total occupancy cost calculations
How Solar Affects Industrial Property Value
From a real estate perspective, solar-equipped industrial properties are commanding a measurable premium in the 2026 market. Here’s why this matters whether you are buying, selling, or leasing:
- Lower operating costs make tenanted industrial properties more attractive to quality occupants
- Higher rental yield potential — landlords with solar can justify slightly higher rents due to lower total occupancy costs for tenants
- GITA-enhanced asset value — a commissioned solar system with documented GITA approval adds a quantifiable financial asset to the property
- ESG compliance — multinational tenants increasingly require green-certified facilities as part of their supply chain sustainability commitments
The Bottom Line
The 2026 industrial rooftop solar opportunity in Malaysia is defined by three converging factors: a favourable new programme (Solar ATAP), a generous but time-limited tax incentive (GITA expiring December 2026), and proven ROI of under 4 years.
Stop viewing your industrial roof as a maintenance liability. Under Solar ATAP 2026, it is a licensed revenue and savings generator — one that pays for itself and continues delivering value for two decades.
The clock is ticking on GITA. The factories that act in the first half of 2026 will have their systems commissioned, their tax allowances secured, and their electricity bills slashed — before the December deadline closes the window.
