Design basis, calculations, interfaces and protection requirements.
EXPONENT NRG
Engineering that connects the design to the operating site.
Coordinate engineering, procurement, installation and integration through testing, commissioning and project handover.
OUR METHODOLOGY
From operating problem to project delivery
01
Define the operating problem.
Review bills, interval load logging, outage records, site conditions and commercial priorities.
Discuss assess02
Build the system around the duty.
Develop the design basis, solar-yield model, load flow, protection interfaces and controls. Select modelling tools to match the study scope.
Discuss engineer03
Test the assumptions before commitment.
Review yield simulations, harmonic and power-quality requirements, structural loads, lifecycle sensitivities and acceptance criteria.
Discuss validate04
Coordinate interfaces and commissioning.
Align procurement, installation, protection testing, SCADA or EMS interface checks and handover with the agreed project scope.
Discuss deliver05
Review performance against the operating plan.
Use measured performance and operating feedback to assess scheduling and system settings.
Discuss optimize06
Plan for operation beyond handover.
Define documentation, training, maintenance responsibilities and support arrangements in the project scope.
Discuss supportQUALITY & LIFECYCLE
Technical rigor, defined in the project scope.
| Design gate | Evidence to establish | Decision it supports |
|---|---|---|
| Equipment qualification | Datasheets, test reports, warranty limits and service support | Suitability for the required duty and environment |
| Structural engineering | Roof capacity, mounting, wind loading and foundation design | A buildable installation with defined structural responsibilities |
| BESS safety integration | Detection, isolation, thermal management, emergency response and any required suppression interfaces | Site-specific risk assessment and authority review |
| Control and acceptance | Interlocks, synchronization, protection, communications and operating-mode tests | Documented handover against agreed criteria |
| Lifecycle support | Telemetry scope, monitoring hours, escalation ownership, maintenance and contractual response targets | Support arrangements appropriate to the facility |
Applicable standards, approvals, monitoring coverage, service levels and performance commitments are established for each project. They are not implied by the illustrative architecture.
A coordinated delivery scope
Technical compliance, documentation, warranty and support review.
Coordinate civil, mechanical, electrical and control interfaces.
Confirm the agreed operating modes and acceptance criteria.
Scope, programme, interface control, quality and handover planning.
Define success before installation
- Agree performance requirements and exclusions.
- Document inspection and acceptance procedures.
- Plan operator training, maintenance access and handover records.
Connect EPC to the energy requirement
Evaluate rooftops or land against daytime demand, structural conditions and the connection strategy before committing to capacity.
Define how each source operates in normal service, supply interruptions and extended outages, with clear load priorities and recovery rules.
Match daily energy, dwell time and electrical headroom before selecting charger power, location and control strategy.
Engineer illumination, pole spacing and operating hours first. Size solar generation and battery autonomy for the lighting duty and seasonal conditions.
Prepare the project brief
Resolve feasibility, sizing and lifecycle questions before committing to delivery.
YOUR NEXT STEP
Turn this requirement into a project brief.
Share your site, operating priorities and available data. Start with an assessment, arrange a survey where needed, then discuss the project scope.
