Investment case
Actual load, roof conditions and expected generation provide the basis for selecting an appropriate capacity and balancing energy benefits with capital investment.
One accountable delivery partner connects site assessment, engineering, procurement, construction and commissioning, helping industrial facilities reduce coordination risk through handover.
EPCC is one delivery scope within 365Energy’s integrated energy solutions.

Rooftop solar PV capacity
C&I projects
In-house workforce
O&M portfolio
Company-wide capabilities based on the 2026 company profile, covering multiple service scopes; not all are EPCC projects.
An effective project approach starts with the facility’s actual needs and constraints: load profile, roof conditions, grid connection, safety, permitting and construction planning.
Actual load, roof conditions and expected generation provide the basis for selecting an appropriate capacity and balancing energy benefits with capital investment.
Structural conditions, fire risk, electrical protection and installation quality need to be addressed from the design stage.
Applicable procedures, approvals and grid-connection requirements need to be identified early for each project.
Construction methods and schedules need to be coordinated with facility operations to limit disruption to production.
Six connected stages link project inputs, delivery work and handover outputs. EPCC covers engineering (E), procurement (P), construction (C), and testing and commissioning (C).
Engineering · Schedule · Quality · Facility coordination
Facility requirements & existing conditions
Assess roof conditions, load profile and operating requirements to establish the basis for a solar PV concept; consider BESS integration where appropriate.
Provides the basis for detailed engineering.
Assessment data & concept basis
Analyse shading and structural conditions, and develop the AC/DC electrical design, protection scheme and safety measures to suit the facility and project scope.
Connects approval requirements with equipment selection.
Concept & applicable conditions
Review applicable grid-connection, construction, fire-safety and environmental procedures; coordinate documentation and project-specific responsibilities among the parties.
Updates the conditions that must be met during delivery.
Approved design & agreed requirements
Select, procure and control equipment and materials against the design; coordinate configuration changes when required.
Provides the approved basis and materials for construction.
Equipment, design & site conditions
Coordinate work areas and production schedules; manage construction methods, safety, schedule and installation quality checks within the project scope.
Provides the basis for testing, commissioning and acceptance.
Installed system & QA/QC records
Complete the tests defined in the project scope, together with the required documentation, guidance and training, to support a structured handover to the facility team.
Supports the transition to operation under the agreed scope.
Stages may overlap or be updated to reflect project conditions. Specific outputs and responsibilities are agreed in the contractual scope.
365Energy establishes technical review gates between stages to identify deviations early and limit rework, schedule delays and operational impact.
Review capacity, shading, structural conditions, cable routes, protection and earthing before procurement to limit design changes once delivery has started.

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

Review equipment quality, certification, configuration and compatibility with the approved design to limit configuration errors or material changes during delivery.

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

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.

Complete documentation, test reports, guidance and training so the operations team receives the technical information needed to take over the system.

Material risks need to be identified before they lead to design changes, schedule delays or disruption to facility operations.
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 risk can directly affect people, assets and insurance requirements. 365Energy incorporates preventive measures from design and equipment selection through QA/QC, testing and operation.
Unclear permitting requirements or approval pathways can affect the schedule. 365Energy reviews applicable requirements and the coordination path before committing to delivery.
Work areas, transport routes and shutdown requirements are reviewed with the facility, with safety measures and the delivery schedule agreed before construction.
Actual generation may differ from expectations. 365Energy uses PVsyst, monitoring and an operations and maintenance plan to track generation and performance.
Unclear responsibilities can delay decisions or create disputes. 365Energy establishes a responsibility matrix and reporting and escalation arrangements from the start of the project.
Workforce structure based on the 2026 company profile. Participating teams and specific responsibilities are defined for each project.
The technical configuration is defined by facility conditions, client requirements, applicable regulations and insurer standards where relevant.
Configuration levels are defined for each project and are not fixed standard packages.
Selected references illustrate how 365Energy adapts its delivery approach to different project conditions, including high wind loads, enhanced safety requirements and energy storage integration.

Key points to clarify before delivering solar PV at an industrial facility.
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.
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.
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.
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.
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.
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.
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.
Share your facility requirements and available project information so 365Energy can define the initial assessment approach. Electricity bills, load profiles and roof documentation can be provided when available.
