ERS Energy Commercial & Industrial Solar

Commercial & Industrial Solar and Battery Storage

Rooftop solar for factories, warehouses, and commercial buildings — with battery storage (BESS) for evening peak hedging. Solar reduces the energy you buy from TNB, and solar + BESS can also reduce peak-demand (capacity and network) charges, helping you manage one of your largest controllable overheads.

Estimate Your Savings

A 30-second gut-check on commercial solar.

Businesses on Non-Domestic tariffs pay an energy charge plus capacity and network (demand) charges. This calculator factors in your industry type and operating hours to separate energy savings from demand-charge reduction. For a full financial model with IRR and NPV, use the C&I ROI Calculator.

Step Three

How others use this.

Two short walkthroughs from finance and operations teams that turned this estimator into a board-ready figure.

Scenario 01

“Electricity is our second-biggest cost. Is solar the answer?”

A food processing facility in Johor with a RM 45,000/month bill running 16 hours a day. Select Food Processing and adjust the hours slider; the calculator factors in the high self-consumption rate typical of processing operations and shows energy plus capacity-charge savings separately.

Result: 510 kWp system, payback 3.7–4.1 years (after GITA), about RM 201,000/year in savings

Scenario 02

“We want to reduce peak demand charges, not just energy bills.”

A retail mall running 12 hours a day. The “Capacity savings” tile shows demand-charge reduction separately from energy savings; in this estimate the solar demand credit is small and capped at 15% of the energy savings, so most of the saving comes from energy.

Business Case

Why Solar Makes Financial Sense for Your Business

Solar isn’t just a sustainability initiative, it’s a financial strategy. Here’s why Malaysia’s leading businesses are investing now.

trending_down

Cut Operating Costs

A 500 kWp factory system saves roughly RM 161,000–197,000 in the first year (NDMV Time-of-Use to General tariff, exported energy not credited), reducing your largest controllable overhead.

electric_meter

Reduce Capacity Charges

Solar + BESS shaves peak demand. A 100 kW reduction saves RM 8,927–9,706/month on NDMV tariffs.

GITA Tax Incentive

GITA: 60% of qualifying solar CAPEX and 100% for BESS, via MGTC, for CAPEX incurred by 31 Dec 2026 (check MGTC for any extension).

Hedge Against Rising Tariffs

Solar power is generated at a cost fixed at installation, offsetting the NDMV energy charge (29.83 sen/kWh on the General tariff) even as tariffs change.

Energy Storage

Why BESS Is the Game-Changer

BESS can cut peak-demand charges through peak shaving. Combined with solar, it can make your cost structure more predictable.

Frequently asked questions

How much does commercial and industrial solar cost?

Cost depends on system size, roof structure and grid connection, so ERS provides a site-specific quotation after a survey. Eligible systems may qualify for the Green Investment Tax Allowance (GITA), and PPA or lease options avoid upfront capex.

What is the typical commercial solar payback period?

Payback depends mainly on daytime load profile and tariff exposure: facilities with high daytime consumption on TNB Medium-Voltage commercial tariffs recover cost fastest, while lighter daytime load or lower tariffs take longer. Use our calculator for an illustrative range for your site.

What changed when NEM 3.0 ended?

NEM 3.0 closed to new applications on 30 June 2025. From 1 January 2026 new rooftop systems connect under Solar ATAP (exports credited at the average system marginal price for non-domestic customers, capped monthly); SelCo (self-consumption, no export) remains available. Companies with high process heat or 24-hour operation now layer battery storage to capture morning generation for evening peak discharge. Existing NEM 3.0 participants keep their terms for the remainder of their 10-year contract.

How does GITA apply to commercial solar?

Under the Green Investment Tax Allowance (GITA) for own consumption, qualifying solar PV capex earns a 60% allowance (BESS 100%), set off against up to 70% of statutory income with unused allowance carried forward, for qualifying capex incurred by 31 Dec 2026. Applications go to MGTC (MyHIJAU-listed equipment); ERS prepares the technical documentation.

When does commercial battery storage make financial sense?

Add battery storage when your evening peak tariff exposure exceeds 30% of monthly bill, or when you operate 24-hour shifts where solar can't cover production hours. SelCo (no export) makes on-site storage more attractive as peak tariff bands rise.

What is a solar PPA and how does it work?

A Power Purchase Agreement is where ERS finances, builds, owns, and operates the system on your roof; you buy the electricity at a fixed per-kWh rate (typically 25% to 40% below TNB) for 15 to 25 years. Zero upfront cost. Off-balance-sheet for many corporate accounting standards. Best for businesses prioritising cash flow over ownership.

Does ERS Energy install on existing metal-deck and concrete roofs?

Yes — we install on standing-seam metal, trapezoidal metal, IBR profile, concrete flat, and concrete pitched roofs. Pre-installation includes a structural assessment to confirm load capacity (typical solar dead load: 18 to 22 kg/sqm). For roofs over 15 years old, we assess condition before installation and recommend re-roofing if needed.

How long is a commercial solar installation?

Site assessment to commissioning takes 12 to 20 weeks for a typical 500 kWp installation. On-site installation is 4 to 8 weeks. The longest phase is grid interconnection approval (TNB SUKA + SEDA registration) which averages 6 to 10 weeks under SelCo. ERS handles all permitting; you focus on operations.

What is the EPC warranty and after-sales coverage?

Tier-1 panels: 25-year linear performance + 12-year product. Inverters: 10-year (extendable to 20). EPC workmanship: 5-year. Mounting structures: 10-year. Optional O&M contracts (5, 10, or 25-year) cover monitoring, scheduled maintenance, panel cleaning, inverter swaps, and performance guarantees.
