Solar Post-Design Services
Turn an approved concept into a buildable package: detailed layout drawings, structural calculations, CEIG electrical drawings and as-built documentation.
What Is Solar Post-Design?
Post-design is the detailed engineering phase that follows preliminary design approval. Once the concept and capacity are signed off, this is the stage that produces the documents your site team, your structural fabricator and the approving authority all work from.
The difference from pre-design is depth and intent. Pre-design exists to visualise and sell; post-design exists to build. Panel placement becomes dimensioned layout drawings, an assumed structure becomes a calculated one, and a single line sketch becomes a CEIG-ready electrical set.
The package is scoped with your team. Structural and electrical elements can be included together or drawn from the dedicated civil, structural and CEIG scopes, depending on how your project is being executed.
What we need from you
- Approved preliminary design or concept layout
- Confirmed module and inverter selections
- Site measurements and structural details
- The approvals your project needs and the authority reviewing them
Tools used
What's Included
Every item below is a documented part of the Solar Post-Design scope.
Detailed Layout Drawings
Complete CAD drawings covering panel placement and wiring, dimensioned for construction rather than for a proposal.
Structural Calculations
Foundation, mounting structure and load analysis for the structure the array will actually sit on.
CEIG Electrical Drawings
Single-line, three-line and schematic diagrams prepared for the electrical approval process.
As-Built Documentation
The final documentation package used for permits and handover once the plant is built.
What the output looks like
Project work delivered by Heaven Designs for solar EPCs and developers.

Who Solar Post-Design Is For
Solar EPCs
Move a signed project into execution without a queue forming at your one in-house design engineer.
Commercial Solar Companies
Get C&I projects documented to the standard a facility owner's consultant will actually review.
Engineering Teams
Add overflow capacity for detailed drafting while your own engineers hold the design authority.
Solar Contractors
Build from a drawing set instead of interpreting a sales layout on site.
Why Detailed Engineering Matters
Fewer Site Improvisations
When the drawing answers the question, the crew does not have to invent a solution and call it a variation.
Structure That Is Calculated
Mounting and foundations sized against real loads rather than carried over from the last similar job.
Approvals Move Faster
Electrical documentation prepared for the approval process from the outset, instead of assembled after a rejection.
A Record That Survives Handover
As-built documentation the customer and your O&M team can still use in year five.
