Sunhub for EPCs & developers
MW-scale procurement, container forwarding, value engineering and escrow.
Procurement structured around the COD
Find cost savings that still pass IE review
Value-engineered alternates get vetted against bankability standards before they reach a project's equipment list.
Manage MW-scale freight as one coordinated flow
Container forwarding tracks volume and sequencing appropriate to a utility-scale mobilization, not individual pallet shipments.
MW-scale solar procurement at delivered $/Wdc
MW-scale solar procurement priced at delivered dollar-per-watt-DC, benchmarked against current market across trackers, modules and BOS.
Delivered $/Wdc pricing across equipment categories
Priced at delivered $/Wdc, not FOB
Procurement pricing reflects the full delivered cost per watt DC, freight and duties included, so a bid built on this number matches what actually lands on an invoice.
Benchmarked across current market, not last cycle
Pricing benchmarks against current market data across trackers, modules and BOS, since utility-scale equipment pricing has moved meaningfully with recent tariff and domestic-content policy changes.
Bundled across the major equipment categories
Modules, trackers and BOS can procure under one coordinated agreement instead of separate negotiations per category, simplifying both pricing and delivery sequencing.
Bid on real delivered cost
Bid on real delivered cost
Pricing includes freight and duties from the start, so a project bid doesn't get undercut by a landed-cost surprise later.
Stay current on a fast-moving market
Benchmarking reflects current tariff and policy conditions, not assumptions from a prior procurement cycle.
Container forwarding from factory floor to laydown yard
Container forwarding from factory floor to laydown yard, coordinated for the volumes a utility-scale mobilization actually generates.
Container coordination from factory to laydown yard
End-to-end coordination, factory to laydown yard
Container tracking and coordination cover the full journey from origin factory through port, drayage and final laydown yard delivery, not a single leg of the trip.
Sequenced to construction phase
Container arrival schedules align with a project's actual construction sequence, so equipment lands when a crew is ready for it rather than staging months of material with nowhere to store it.
Volume handled as one coordinated flow
Multiple containers across suppliers and origins get managed as a single coordinated schedule instead of dozens of individually tracked shipments.
Freight timed to the build schedule
Match freight timing to construction phase
Container delivery sequences against the build schedule instead of arriving in an unplanned wave.
Manage one freight schedule instead of many
Multiple containers and origins consolidate into one coordinated tracking view.
Phase-aligned material staging for MW-scale builds
Material staging sequenced against a MW-scale build's construction phases, so equipment shows up as each phase needs it.
Material staging sequenced to construction phases
Staging sequenced to the build, not delivered all at once
Equipment arrives as each construction phase actually needs it, avoiding the cost and site congestion of staging an entire project's material before there's anywhere to put it.
BESS delivery on its own construction timeline
Battery storage often installs on a different schedule than the solar array itself, and staging accounts for that separate sequencing rather than treating storage as an afterthought to module delivery.
Flexible to schedule shifts
Staging plans adjust when a construction schedule moves, rather than locking a delivery date that no longer matches the site's actual readiness.
Avoid staging costs and congestion
Avoid staging costs and site congestion
Material arrives phase by phase instead of all at once with nowhere to store it.
Keep BESS on its own accurate timeline
Storage delivery sequences against its actual installation phase, not bundled with module delivery.
Single-line diagrams that accelerate permits and interconnection
Single-line diagrams built to accelerate permitting and interconnection review, not just satisfy a checklist requirement.
Single-line diagrams built for interconnection review
Built for the reviewer, not just the checklist
SLDs draft with the level of detail a utility interconnection engineer specifically looks for, cutting the round-trip of clarifying questions that slows a study down.
Scaled to utility-scale complexity
Diagrams cover the protection, metering and multiple-inverter-block detail a utility-scale project needs, beyond what a commercial-scale single-line typically requires.
Fast revision when a study raises a question
Diagrams update quickly when an interconnection study comes back with a technical question, instead of restarting a drafting cycle each time.
Faster movement through interconnection
Move faster through interconnection review
Diagrams anticipate what a utility engineer checks for, reducing rounds of clarifying questions.
Respond to study questions without a drafting delay
Fast revision keeps an interconnection study moving instead of stalling on a documentation turnaround.
Spec-equivalent alternates that still clear the IE
Spec-equivalent equipment alternates that still clear an independent engineer's review, opening cost savings without compromising bankability.
Equipment alternates that clear IE review
Alternates screened for real equivalence
Substitute equipment gets evaluated against the original spec's actual performance and durability characteristics, not just a similar price point, before it's proposed as a value-engineered option.
Vetted against IE review standards
Alternates get checked against the criteria an independent engineer typically applies during bankability review, reducing the risk a proposed substitution gets rejected late in financing diligence.
Savings that don't cost bankability
The goal is cost reduction that survives project financing scrutiny, not a cheaper part that saves money upfront and creates a financing problem later.
Savings that pass financing diligence
Find savings that actually clear diligence
Alternates are pre-screened against IE standards before they reach a financing conversation.
Reduce cost without reopening bankability questions
Substitutions target genuine equivalence, not just a lower price tag.
Guides for your next decision
Your questions, answered.
How does EPC procurement differ from standard commercial equipment sourcing?
EPC procurement is built around a project schedule and a fixed commercial-operation date, not a one-off purchase. It involves megawatt-scale volumes, container-level freight and forwarding, staged delivery aligned to construction phases, and financing structures like escrow and bonding. Equipment also has to clear independent-engineer and bankability review, so selection weighs documentation and compliance alongside price. Sunhub structures procurement around the COD rather than around vendor availability.
Can escrow and freight be structured around a specific COD deadline?
Yes. Escrow milestones and container freight can both be sequenced to the project timeline, so payments release and shipments land in the order construction actually needs them, with the commercial-operation date as the anchor. That keeps delivery from slipping behind vendor availability and gives the schedule a procurement backbone rather than a set of disconnected orders.
Does value engineering compromise a project's bankability?
It does not have to. Sound value engineering substitutes equivalent or better components and reworks design choices for cost without dropping below the specifications an independent engineer and lender require. The risk appears when substitutions are made purely on price and cannot pass IE review, so the discipline is finding savings that still clear bankability. We aim value engineering at alternates that survive that review.
How is delivered dollar-per-watt-DC calculated across a full bill of materials?
Delivered dollar-per-watt-DC totals the landed cost of the full bill of materials, modules, trackers, and balance-of-system, including freight, duties, and any tariff exposure, then divides by the system's DC nameplate wattage. Unlike an FOB or ex-works figure, it reflects what the equipment actually costs at the site. That makes it the number to bid against, because it captures logistics and trade cost that FOB pricing leaves out.
Does MW-scale procurement include allocation guarantees on tight timelines?
Allocation and delivery commitments depend on the manufacturer, the equipment category, and current market conditions, so they are negotiated deal by deal rather than assumed. On tight timelines, securing allocation early and in writing is what protects a schedule. Sunhub benchmarks against the current market so those commitments reflect real availability, not last cycle's.
More questions about these services
Can procurement bundle modules, trackers and BOS under one agreement?
Yes. MW-scale procurement can bundle modules, trackers, and balance-of-system under one agreement priced at delivered dollar-per-watt-DC. Bundling the major categories simplifies the bill of materials, aligns delivery, and gives a single benchmarked cost to bid against instead of stitching quotes together.
How does container forwarding for an EPC differ from standard ocean freight?
Standard ocean freight moves a shipment from port to port, while EPC container forwarding coordinates the whole flow from the factory floor to the project laydown yard. It's built around utility-scale volumes and sequenced to the construction schedule rather than treated as isolated shipments. That end-to-end coordination is what separates it from booking containers one at a time.
Can freight be sequenced to match a construction schedule instead of arriving all at once?
Yes, sequencing to the construction phase is the point, so material arrives when each stage needs it rather than landing all at once and crowding the laydown yard. Matching freight timing to construction reduces demurrage, storage strain, and handling. Sunhub manages the volume as one coordinated flow tied to the build schedule.
Does forwarding include laydown yard coordination at the destination?
Yes, the forwarding covers the destination end, including laydown yard coordination, so delivery lines up with how the site is receiving and staging material. Handling the full path from factory to yard means the timing and volume are managed together rather than handed off at the port. That keeps one freight schedule instead of many disconnected ones.
Why does material staging need to align with construction phase on a MW-scale build?
On a MW-scale build, delivering everything at once creates storage cost, site congestion, and damage or theft risk before the crew is ready to install it. Staging sequenced to each construction phase means equipment arrives as that phase needs it. Sunhub sequences staging to the build rather than dropping it all on day one.
Does phase-aligned staging apply to BESS delivery as well as solar equipment?
Yes. Battery energy storage often follows its own construction timeline separate from the PV modules and racking, so its delivery is staged to when the storage scope is actually ready. Keeping BESS on its own accurate timeline avoids parking sensitive, high-value equipment on site too early.
What happens if a construction schedule shifts after staging is planned?
A well-built staging plan is flexible to schedule shifts, adjusting delivery windows as phases move rather than forcing the original dates. Communicating the change early lets the staging resequence around the new timeline. Sunhub builds staging to flex with the schedule instead of locking it in.
How does a well-built SLD actually speed up interconnection review?
A clear, complete single-line diagram gives the interconnection engineer the protection, configuration, and point-of-interconnection detail they need to sign off without sending the drawing back for clarification. Every avoided redline or request for information removes a round-trip that would otherwise stall the queue. Built for the reviewer rather than a checklist, the drawing moves through review with fewer cycles.
Does an EPC-scale SLD need different detail than a commercial-scale one?
Yes, utility-scale projects add complexity, multiple inverters and combiner levels, medium-voltage collection, transformers, and more involved protection and metering, that a commercial-scale single-line can handle more simply. The drawing has to scale to that complexity while staying readable for the reviewer. Matching detail to project scale is what keeps a large-project SLD both complete and reviewable.
Can SLDs be revised quickly as an interconnection study raises questions?
Yes, and fast turnaround matters, because interconnection studies routinely raise questions that require an updated drawing before review continues. Being able to revise the SLD quickly means responding to a study question without a drafting delay that idles the queue position. Quick revision keeps the project moving instead of waiting on the diagram.
What does spec-equivalent mean for a value-engineered equipment alternate?
Spec-equivalent means the alternate meets the same technical and performance requirements as the specified equipment, ratings, certifications, warranty terms, and performance figures, so it is a true substitute rather than a cheaper part that falls short. The point is savings that hold up under scrutiny, not a downgrade dressed up as an equal.
Does an alternate need independent engineer approval before it can be used?
On bankable projects, yes, an equipment alternate typically has to clear the independent engineer's review before it can be substituted, since the IE protects the financing party's assumptions. Sunhub screens alternates against IE review standards up front so they are more likely to clear diligence rather than getting kicked back late in the process.
Can value engineering find savings without affecting bankability?
Yes, that is the whole aim. By limiting alternates to genuinely spec-equivalent equipment that still clears the independent engineer's review, you capture cost savings without reopening the bankability questions that a true downgrade would raise. Savings that fail diligence are not savings, so equivalence is screened before the alternate is proposed.
