START WITH THE FACILITY CHALLENGE

Reduce risk from the outset

An effective project approach starts with the facility’s actual needs and constraints: load profile, roof conditions, grid connection, safety, permitting and construction planning.

01

Investment case

Actual load, roof conditions and expected generation provide the basis for selecting an appropriate capacity and balancing energy benefits with capital investment.

02

System safety

Structural conditions, fire risk, electrical protection and installation quality need to be addressed from the design stage.

03

Compliance & approvals

Applicable procedures, approvals and grid-connection requirements need to be identified early for each project.

04

Operational continuity

Construction methods and schedules need to be coordinated with facility operations to limit disruption to production.

06 DELIVERY STAGES

From site assessment to handover

Six connected stages link project inputs, delivery work and handover outputs. EPCC covers engineering (E), procurement (P), construction (C), and testing and commissioning (C).

TECHNICAL REVIEW GATES

Quality controls at every stage

365Energy establishes technical review gates between stages to identify deviations early and limit rework, schedule delays and operational impact.





ENGINEERING

Design review

Review capacity, shading, structural conditions, cable routes, protection and earthing before procurement to limit design changes once delivery has started.

HSE & QA/QC

Check connections, torque, polarity, installation quality and project-specific QA/QC points to identify issues before they become operational faults.

04Testing & commissioning
TESTING & COMMISSIONING

Perform insulation-resistance, I–V curve, thermal and protection-device functional tests, together with other tests defined in the project scope, before the system enters operation.

PRE-DELIVERY REVIEW

Identify risks early

Material risks need to be identified before they lead to design changes, schedule delays or disruption to facility operations.






Roof structureProject-specific review required

An inadequately assessed roof structure can affect safety and lead to design changes. 365Energy reviews structural conditions and arranges an independent assessment where needed before finalising the implementation approach.

Fire riskProject-specific review required

Fire risk can directly affect people, assets and insurance requirements. 365Energy incorporates preventive measures from design and equipment selection through QA/QC, testing and operation.

Approval delaysProject-specific review required

Unclear permitting requirements or approval pathways can affect the schedule. 365Energy reviews applicable requirements and the coordination path before committing to delivery.

Production disruptionProject-specific review required

Work areas, transport routes and shutdown requirements are reviewed with the facility, with safety measures and the delivery schedule agreed before construction.

System performanceProject-specific review required

Actual generation may differ from expectations. 365Energy uses PVsyst, monitoring and an operations and maintenance plan to track generation and performance.

Responsibility gapsProject-specific review required

Unclear responsibilities can delay decisions or create disputes. 365Energy establishes a responsibility matrix and reporting and escalation arrangements from the start of the project.

QUICK ANSWERS

Frequently asked questions

Key points to clarify before delivering solar PV at an industrial facility.

What does EPCC include?

EPC covers engineering, procurement and construction. In EPCC, commissioning is explicitly included in the delivery scope. The scope of work, responsibilities and exclusions are defined for each project and contract.

What information is needed initially?

The facility should share its project objectives, location and relevant operating conditions. If available, electricity bills, load profiles, electrical single-line diagrams and roof drawings help the engineering team assess the project more quickly; missing data can be added during the site assessment.

What does the delivery process involve?

The process usually starts by clarifying requirements, assessing the site and developing a concept, followed by engineering, procurement, construction, testing and commissioning, then handover. Technical outputs are reviewed at each stage to limit deviations and changes during delivery.

Who coordinates permits and approvals?

Responsibilities for documentation, procedures and approvals are defined for each project. 365Energy can coordinate requirements within its service scope, while the project owner, facility and other relevant parties fulfil obligations that fall within their responsibility or authority.

Will construction affect production?

It can, particularly during equipment transport, work in operational areas or electrical connection activities. Safety measures, the construction schedule and any required power interruptions are coordinated with the facility to reflect actual project conditions.

When are the cost and schedule finalised?

An initial estimate can be prepared from basic data. Cost and schedule can be defined more accurately once site conditions, technical configuration, scope of work and delivery requirements are clarified; subsequent changes are assessed based on their actual impact.

What is included at handover?

Depending on the project scope, handover may include technical documentation, testing and commissioning results, and operational guidance. Warranty obligations and the O&M scope are defined in the contract; long-term O&M is not automatically included in every EPC or EPCC package.
