Savings per Month
Malaysia's logistics sector is quietly becoming one of the fastest-growing solar markets. Petronas logistics arms, Pos Malaysia hubs, e-commerce fulfilment centres, and cold chain operators are all signing solar contracts in 2026 — and for good reason.
Warehouses are arguably the perfect buildings for solar. This guide explains why — and provides detailed ROI numbers broken down by warehouse type.
Why Warehouses Are Ideal for Solar
Large flat roofs
Warehouses have the highest roof-to-floor area ratio of any commercial building type. A 10,000 sqm warehouse roof can host 500–700kWp of solar.
Daytime electricity use
Loading bays, forklifts, conveyor systems, office areas, and lighting all operate during daylight hours — precisely when solar generates maximum power.
High electricity consumption
Cold storage, climate-controlled facilities, and large lighting arrays drive high monthly TNB bills — meaning more cost to offset with solar.
Rising energy costs
The ICPT surcharge and TNB tariff increases since 2022 have hit warehouse operators hard. Solar provides a 25-year electricity price hedge.
GITA eligibility
Logistics companies owning their warehouse can claim the 60% GITA tax allowance before December 31, 2026 — reducing effective solar cost by 14%.
ESG & shipper requirements
Global FMCG and e-commerce brands (Unilever, Shopee, Amazon) are requiring logistics partners to report Scope 3 emissions. Solar directly lowers carbon intensity.
ROI by Warehouse Type
1. Cold Storage Warehouses
Cold storage is the highest-ROI warehouse solar application. Refrigeration compressors are power-hungry, typically drawing 150–400kW continuously. In Malaysia's heat and humidity, compressors run near maximum capacity year-round — creating a reliable, predictable electricity load that solar can directly offset.
- Typical electricity bill: RM80,000–RM250,000 per month
- Solar self-consumption rate: 75–90% (compressors absorb most of the generation)
- Recommended pairing: Solar + BESS (battery storage) to extend coverage into evening peak hours
- Expected savings with 250kWp solar: RM25,000–RM40,000/month
- Payback period: 2.5–3.5 years
2. 3PL (Third-Party Logistics) Warehouses
3PL operators face intense cost pressure from shippers demanding lower rates while input costs rise. Energy is typically the second-largest cost after labour. Solar directly reduces the energy line, improving margins without operational changes.
- Typical electricity bill: RM30,000–RM100,000 per month
- Best for: Ambient-temperature multi-client warehouses with 24/5 operations
- Key benefit: Differentiates the 3PL as a green logistics provider for ESG-conscious customers
- Expected savings with 100kWp solar: RM7,000–RM10,000/month
- Payback period: 3.5–4.5 years
3. E-Commerce Fulfilment Centres
E-commerce warehouses operate extensive conveyor systems, automated sorting equipment, and large LED lighting grids — all high daytime consumers. Many are also under sustainability commitments from platform operators (Shopee, Lazada, TikTok Shop).
- Typical electricity bill: RM50,000–RM200,000 per month
- Solar advantage: High self-consumption due to equipment operating during day shifts
- Expected savings with 200kWp solar: RM18,000–RM28,000/month
- Payback period: 3–4 years
4. Manufacturing-Adjacent Warehouses
Finished goods warehouses attached to manufacturing plants often share the factory's Maximum Demand (MD) contract with TNB. Solar can reduce the MD billing peak, delivering a double saving: lower energy unit cost AND lower MD charges.
- MD charge impact: Every 1kW reduction in maximum demand saves RM97.06/month (MV tariff, post-Jul 2025 RP4)
- Expected MD savings with 100kWp solar: RM5,000–RM15,000/month in MD charge reduction alone
- Total payback period: 2.5–3.5 years including MD savings
Price and ROI Table by Warehouse System Size
| System Size | Roof Area Needed | All-In Cost | Monthly Savings | Payback | 25-yr IRR |
|---|---|---|---|---|---|
| 30kWp | ~180 sqm | RM 92,000 | RM 2,100–2,800 | 4–4.5 years | 15–18% |
| 50kWp | ~300 sqm | RM 150,000 | RM 3,500–4,500 | 3.5–4 years | 18–21% |
| 100kWp | ~600 sqm | RM 300,000 | RM 7,000–10,000 | 3–4 years | 20–24% |
| 250kWp | ~1,500 sqm | RM 700,000 | RM 17,000–25,000 | 3–3.5 years | 22–26% |

Cold Storage + BESS: The Full Energy Stack
Cold storage operators who pair solar with a Battery Energy Storage System (BESS) unlock a significantly enhanced ROI. Here is why:
- Peak shaving: BESS charges during off-peak TNB hours (11pm–7am, lower rates) and discharges during peak hours (8am–10pm). For cold storage facilities on TOU tariffs, this can save an additional RM5,000–RM15,000/month.
- MD charge reduction: BESS absorbs demand spikes from compressor start-up transients, directly reducing your Maximum Demand billing peak. At RM97.06/kW/month, every kW saved is significant.
- Backup power: TNB outages cost cold storage operators RM20,000–RM200,000 per incident in spoilage losses. A properly-sized BESS provides 2–4 hours of backup for critical refrigeration loads.
- GITA eligibility: BESS (battery systems installed as part of a renewable energy system) is a qualifying asset under GITA. The combined solar + BESS capex qualifies for the 60% allowance.

GITA Eligibility for Logistics Companies
GITA Deadline: December 31, 2026
- Logistics, 3PL, cold chain, and e-commerce companies are all eligible
- Must be a Malaysian-incorporated Sdn Bhd or Bhd
- Must own the warehouse premises (long-term leases may qualify with landlord consent)
- MIDA application must be submitted BEFORE installation begins
- System must be commissioned before December 31, 2026
For a typical 100kWp warehouse solar installation (RM300,000 capex), the GITA allowance delivers RM43,200 in tax savings over 5 years for a company at 24% corporate tax rate. For a 250kWp system (RM700,000 capex), the GITA tax savings reach RM100,800.

Frequently Asked Questions
Is solar worth it for a warehouse in Malaysia?
Yes — warehouses deliver some of the highest solar ROIs in Malaysia due to large flat roofs, high daytime electricity consumption, and excellent self-consumption rates. Typical payback is 3–4 years with a 25-year system lifespan and 20–25% IRR.
How much can a cold storage warehouse save with solar?
A cold storage warehouse with a 200kWp solar system can save RM25,000–RM40,000 per month. Adding BESS extends savings into evening peak periods and provides MD charge reduction, pushing total monthly savings higher.
Can a logistics company claim GITA for warehouse solar?
Yes. Any Malaysian-incorporated logistics company that owns the warehouse premises can claim the 60% GITA tax allowance before the December 31, 2026 deadline. MIDA application must be submitted before installation begins.
What size solar system is right for a 50,000 sq ft warehouse?
A 50,000 sq ft warehouse roof can typically accommodate 200–300kWp of solar. At 250kWp, expect RM700,000 all-in cost, RM17,000–RM25,000 monthly savings, and payback in approximately 3–3.5 years.
