Equipment scope

Set the supply scope before the delivery sequence.

Utility projects depend on compatible grid-side equipment, clear documentation and planned delivery. We support buyers building a coordinated package around those conditions.

01

Array equipment

High-volume module supply matched to array layout and project schedule.

02

Transformers

Distribution and power transformer options for solar and substation scope.

03

Grid interfaces

Switchgear and distribution equipment for protection and interconnection.

Before quotation

Confirm the project conditions first.

Supply scope: equipment selection, material supply and documentation coordination. Permitting and site installation are completed by the buyer’s qualified installer or contractor where required.

  1. Single-line diagram, design voltage and interconnection requirements.
  2. Array capacity, equipment schedule and preferred delivery sequence.
  3. Receiving constraints, destination and documentation requirements.

Utility project matching

Coordinate utility supply around the grid design and delivery sequence.

Utility projects require a matched package across the array, transformation and grid interface. We help translate the project documents and construction sequence into a coordinated equipment supply scope.

01

Grid design inputs

Single-line diagram, capacity, voltage, interconnection requirements and protection approach.

02

Supply sequence

Array quantities, transformer and switchgear scope, delivery phasing and receiving constraints.

03

Project assurance

Requested product documents, destination-market requirements and commercial terms confirmed for the order.

Configuration context

Align array, transformation and grid interfaces from the start.

Large projects move more smoothly when the electrical design, documentation needs and receiving sequence are reflected in one supply plan. We use those project inputs to match equipment categories and timing.

System overview

See the grid-connected energy system as one coordinated scope.

This overview brings solar PV, storage, transformation, distribution and grid interfaces into one discussion. The final supply scope is then aligned to the electrical design, interconnection requirements and delivery sequence.

APPLICATION ENGINEERING

Typical utility-scale supply scope

Indicative ranges for ground-mount and grid-interconnection projects. The supply sequence is built around your construction milestones, not around a single delivery date.

Array size1 MW upward, released in blocks
Modules600 to 720 W, up to 23.5% module efficiency
InvertersCentral inverters or high-capacity string units

Illustrative selection information. Confirm the final specification for your model, site and delivery scope.

ItemTypical specificationWhat decides it
Array size1 MW upward, released in blocksConstruction sequence and laydown area
Modules600 to 720 W, up to 23.5% module efficiencyTracker or fixed structure, string voltage
InvertersCentral inverters or high-capacity string unitsBlock layout, O and M strategy
MV transformer2,500 to 10,000 kVA, ONAN or ONAF coolingStep-up requirement and grid code
MV switchgearUp to 31.5 kA short-circuit withstandFault level from the network operator

Indicative ranges for enquiry planning. Final values follow the site review and are confirmed in writing on your quote.

What usually goes wrong on this kind of project

  • One delivery date agreed instead of a milestone-based release sequence, which overloads site laydown.
  • Transformer impedance and switchgear ratings sourced from different suppliers and never reconciled.
  • Tracker stow wind case left out of the foundation design, then discovered during a weather event.
  • Grid-interconnection documentation (IEEE 1547 / UL 1741 conformance) incomplete, holding up energisation.

Questions buyers ask

Can you deliver against our construction schedule?

Yes. We agree block releases against your milestones so equipment arrives as each section is ready, not all at once.

Should the transformer and switchgear come from one supplier?

We recommend it. Impedance, fault level and protection discrimination have to be consistent, and two separate quotes rarely are.

Tracker or fixed tilt?

Trackers raise yield but add drives, controllers and a stow wind case. Fixed tilt stays the default where land is tight or O and M resource is limited.

What test documentation ships?

Nameplate data and test reports to the applicable IEC or ANSI / IEEE standard, with drawings issued for approval before production.
