Designing Rooftop Solar with Confidence: Electrical Engineering

Industry: Renewable Energy / Solar PV
Location: White Rock, British Columbia, Canada

Scope : Electrical engineering design, structural feasibility coordination, rooftop layouts, permit support, and approved-for-construction drawing package for two rooftop solar installations 
Software: AutoCAD and engineering drafting/design workflows

The Challenge

Turning rooftop solar ambition into a permit-ready, buildable design 

The client set out to advance rooftop solar installations across two buildings in White Rock, BC. To move from concept to construction, the project required more than panel placement, it needed a coordinated electrical and structural engineering approach that could support technical review, permit submission, and field execution. 

Because rooftop solar design sits at the intersection of building constraints, electrical integration, and code compliance, the client needed a partner who could align feasibility, detailed design, and documentation into one dependable workflow. 

  • Two rooftop installations required a coordinated, site-specific engineering approach 
  • Electrical design needed to align with roof conditions, existing building constraints, and solar equipment requirements 
  • Structural feasibility had to be reviewed to support safe rooftop loading and permit readiness 
  • The final package needed to be clear, construction-ready, and suitable for building permit submission 

The Objective

Deliver a complete electrical engineering concept that could move confidently into construction 

The goal was to develop a robust engineering package for two rooftop solar installations covering concept development, detailed electrical design, and supporting structural feasibility so the client could proceed with confidence toward construction and permitting. 

  • Assess rooftop suitability and define the technical basis for solar installation 
  • Produce key electrical engineering deliverables including single – line diagrams, wiring diagrams, and bill of materials 
  • Develop rooftop layouts and equipment arrangements that reflected real site conditions 
  • Support permit submission and provide a final drawing package approved for construction 

Why Prozus

An engineering partner that connects concept, compliance, and constructability 

The client engaged Prozus for our ability to bring together electrical engineering, drafting, quality control, and cross-discipline coordination in a single delivery model. Rather than treating design as a set of isolated drawings, we approached the project as an integrated engineering solution – one that balanced rooftop realities, system performance, and permit-readiness from the outset. 

This combination of technical rigor and practical execution helped ensure the final deliverables were not only technically sound, but also usable by stakeholders responsible for review, approval, and construction. 

Our Approach

Phase 1: Feasibility, data review, and concept development 

Prozus began by reviewing available project information and defining the engineering path forward for two rooftop solar installations. The early phase focused on building a dependable design foundation – capturing rooftop conditions, reviewing as-built information, and aligning structural and electrical considerations before detailed design advanced. 

  • Reviewed available as-built information and project inputs for both buildings 
  • Prepared 2D rooftop layouts to capture roof dimensions, features, and obstructions 
  • Coordinated structural feasibility review to confirm rooftop suitability for solar installation 
  • Established the basis of design for the solar PV electrical system and associated equipment 

 

Phase 2: Detailed electrical engineering and construction documentation 

With the technical basis established, Prozus advanced the design into a complete engineering package. This included the core electrical documentation needed to support installation planning, review, and field execution while maintaining alignment with structural requirements and permit needs. 

  • Developed preliminary, detailed, and construction-level electrical deliverables 
  • Produced single-line diagrams, wiring diagrams, and bill of materials 
  • Prepared panel layout and arrangement details where required 
  • Coordinated structural deliverables to support building permit submission 
  • Applied quality control across the drawing set to improve clarity, consistency, and readiness for issue 

The Results

From concept to approved-for-construction drawings 

Prozus successfully translated the client’s rooftop solar vision into a practical engineering package for two buildings in White Rock. The final deliverables provided the technical clarity needed to move the project forward supporting both execution in the field and review by permitting stakeholders. 

The completed project culminated in stamped engineering drawings approved for construction, helping enable building permit obtainment and giving the client a reliable foundation for rooftop solar installation. 

  • Electrical and structural design concept delivered for two rooftop solar installations 
  • Detailed engineering drawings prepared to support field execution and stakeholder review 
  • Permit-oriented documentation provided to help advance building approval requirements 
  • Approved – for – construction package delivered to move the project into the next stage with confidence 

Proven Value, Scaled Forward

A repeatable model for solar engineering delivery 

This project demonstrates how a coordinated engineering workflow can reduce friction between concept, design, and permitting for rooftop solar initiatives. By integrating electrical design, structural coordination, drafting, and quality control, Prozus helped create a repeatable model that can be applied to future solar projects with similar speed, clarity, and discipline.

The Prozus Difference: Why it Matters

Engineering that helps clean energy move faster 

In renewable energy projects, momentum depends on more than intent – it depends on deliverables that are technically sound, clearly documented, and ready for real-world use. This engagement reflects Prozus’ ability to support that momentum through engineering packages that bridge feasibility, compliance, and constructability. For clients pursuing rooftop solar, that means fewer gaps between vision and execution and a smoother path to installation.
