ERS Energy C&I Projects

1.9 GWp+. 17 Years. Proven Commercial Solar.

From beverage bottling and food manufacturing to a sawmill and a fuel-station network, ERS Energy’s C&I portfolio is built around engineering each roof for its own conditions. With GITA capital allowances for qualifying CAPEX incurred by 31 Dec 2026 (60% for solar, 100% for BESS, via MGTC), C&I solar has never been more accessible.

Featured Projects

Six real ERS Energy installations, each shown with the engineering challenge it posed and how the EPCC cycle — engineering, procurement, construction, commissioning and O&M — was delivered. Client names are withheld. All systems use Tier-1 equipment from leading panel and inverter manufacturers.

Beverage bottling plant

The engineering challenge

Large low-slope roofs already carry plant services, vents and skylights, so design starts with a structural loading and roof-condition survey, not a module count. Work is sequenced around live bottling lines, with tie-ins made in short shutdown windows, and long DC cable runs across wide roofs shape string design and voltage-drop control.

EPCC delivery cycle
  1. EngineeringRoof survey, structural check, shading and yield modelling, single-line design
  2. ProcurementModules, inverters, clamp-on roof mounting and cabling
  3. ConstructionRooftop installation under permit-to-work, with lifelines and edge protection
  4. CommissioningProtection tests to utility requirements and monitoring set-up
  5. O&MPerformance monitoring, cleaning and inverter servicing

Fuel-station network rollout

The engineering challenge

Every site differs — canopy age, roof sheet profile, tie-in point — yet the owner needs one repeatable design. The team builds a standard kit and design template, then handles site exceptions: canopy loading, hazardous-area clearances on the forecourt, and work at height over operating pumps with customers present. Scheduling and quality control across many small sites is the main risk.

EPCC delivery cycle
  1. EngineeringSite survey template, standard design and per-site exceptions
  2. ProcurementBulk standardised kits and spares
  3. ConstructionWork at height on live forecourts by phased site crews
  4. CommissioningRepeatable test and handover pack for every site

Manufacturing

Light manufacturing plant, Banting, Selangor

The engineering challenge

Older factory roofs mix roof types and ages, so each roof zone needs its own structural and waterproofing check before mounting. Inverters and switchgear must fit the existing electrical rooms, and the tie-in has to be made without stopping production.

EPCC delivery cycle
  1. EngineeringRoof assessment, layout and protection design
  2. ProcurementModules, inverters, mounting and switchgear
  3. ConstructionInstallation on the existing roof with no production stoppage
  4. CommissioningTesting, tie-in and energisation
  5. O&MMonitoring and routine servicing

Wood processing

Timber sawmill

The engineering challenge

Sawmill roofs range from freshly re-sheeted to old corrugated sheets, so structural and corrosion checks decide which roofs can carry panels. Wood dust and stored timber make fire risk a design input for cable routing, isolation and inverter placement, and arrays spread over many buildings need several combiner points plus careful earthing and lightning design.

EPCC delivery cycle
  1. EngineeringRoof-by-roof capacity survey, fire-safety layout, earthing and lightning design
  2. ProcurementModules, inverters, combiners and mounting suited to mixed roofs
  3. ConstructionPhased multi-building work around an operating mill
  4. CommissioningTesting and staged energisation across buildings

Food manufacturing

Food manufacturing plant

The engineering challenge

An extensive roof with many penetrations — vents, skylights, HVAC — forces an irregular layout that must still balance strings and keep inverter MPPT inputs matched. Food-hygiene and access rules limit contractor movement, and the added roof load has to be checked against the design reserve.

EPCC delivery cycle
  1. EngineeringIrregular-layout string design, MPPT matching and roof load check
  2. ProcurementModules, inverters and mounting for large roofs
  3. ConstructionInstallation under hygiene and access controls, coordinated with plant hours
  4. CommissioningStaged energisation

Food ingredients

Food-ingredient plant with solar carports

The engineering challenge

Carports are custom steel structures that need wind-uplift, foundation and drainage design, with bifacial glass modules above the parking bays. Works were phased around an operating plant, including night-time cabling and commissioning.

EPCC delivery cycle
  1. EngineeringStructural steel design and bifacial yield modelling
  2. ProcurementStructure fabrication and modules

“We were sceptical about the payback projections — our CFO stress-tested every assumption. But ERS’s numbers held up. Our NDMV General demand charges dropped 35% in the first month. The GITA claim through MGTC reduced our effective system cost.”

“The PPA model was the deciding factor — zero upfront cost, and we pay a fixed PPA rate well below our TNB rate. That’s a discount from day one. ERS handled the SEDA registration, TNB interconnection approval, and all metering. Our only regret is not starting sooner.”
