Solar Design & Engineering Services

Commercial and industrial solar projects need accurate layouts, strong technical assumptions and practical design coordination.

Nortcel supports warehouses, factories, offices, schools, universities, public sector buildings, retail sites and complex commercial rooftops with proposal level, PPA level and detailed solar design and engineering services.

What we support

Proposal and PPA level design
Layouts, capacity estimates, generation assumptions and technical inputs for quotations, tenders, PPA discussions and client approval.

Detailed design packs
PV layouts, system sizing, stringing strategy, electrical design input, single line diagrams and technical documentation.

Mounting system design
Roof mounted system layouts, mounting approach, fixing coordination and practical buildability support.

Best for
Installers, EPCs, commercial property owners, public sector clients, PPA companies and renewable energy teams.

Utility scale solar projects require clear design logic across land use, generation, access, electrical strategy, grid connection and project economics.

Nortcel supports ground mounted and large scale solar PV projects from concept stage to PPA level design and technical development.

What we support

Concept and PPA level design
Site layouts, capacity studies, generation assumptions and early technical inputs for commercial modelling and project evaluation.

Technical design coordination
Layout optimisation, inverter strategy, stringing logic, access considerations and project documentation.

Mounting system design
Ground mount layout support, row spacing, table configuration, orientation, tilt and coordination with site constraints.

Best for
Developers, EPCs, renewable energy teams, PPA companies and organisations developing large scale solar opportunities.

Early stage solar opportunities often need technical input before detailed design, tendering or investment decisions.

Nortcel helps project teams assess what is technically possible and what information is needed before moving to the next stage.

What we support

Site feasibility
Reviewing available space, access, constraints, grid considerations and development potential.

Capacity studies
Estimating suitable PV capacity based on land, roof area, setbacks, mounting options and project objectives.

Development documentation
Clear technical information to support internal decisions, tenders, PPA discussions and stakeholder review.

Best for
Developers, landowners, PPA companies, public sector organisations and renewable energy teams.

→ Discuss Development Support

An independent design review helps identify technical risk before a solar PV, battery or renewable energy project moves into procurement, approval, construction, handover or investment.

Nortcel provides remote third-party design risk review for public sector bodies, PPA providers, asset owners, developers, contractors, EPCs and organisations that need independent technical assurance before committing.

What we review

Design suitability
Array layouts, system sizing, design assumptions, equipment selection and overall technical suitability for the site and project objective.

Technical documentation
Design packs, single line diagrams, contractor submissions, technical schedules, tender information and handover documentation.

Performance assumptions
Yield expectations, consumption matching, export assumptions, PPA inputs, savings logic, battery sizing assumptions and missing data.

Risk and information gaps
Incomplete inputs, weak assumptions, coordination issues, technical inconsistencies and design risks that could affect cost, programme or performance.

Mounting and buildability
Mounting approach, layout practicality, roof or ground constraints, access, maintenance considerations and installation logic.

Best for
Public sector clients, PPA providers, asset owners, developers, contractors, EPCs and organisations that need independent design assurance before approving a project.

Residential solar projects still need accurate, clear and professional design work.

Nortcel supports domestic installers with fast, reliable PV design for straightforward homes and more complex roof structures.

What we support

Rooftop layouts
Clear PV layouts for domestic roofs, including different orientations, roof shapes and obstructions.

System sizing
PV capacity, inverter selection support and performance estimates.

Mounting and documentation
Mounting layout coordination, electrical design information and professional design packs for installer use.

Best for
Residential solar installers and companies delivering domestic rooftop PV projects.
