The Sepi Design & Engineering Process
Eliminating Change Orders through Collaboration & Efficiency
The success of every solar project relies on the accuracy of a complete permit set. But not every solar engineering firm produces permit sets in the same way. Sepi uses a proprietary process with which we provide you with check points at 10%, 30%, 60%, 90% and 100% of project completion, which allows you to make revisions—without project-slowing change orders—all while we continue developing the full permit set. Our process means your projects are always accurate and cost-efficient.
Once an NDA and all appropriate estimates are approved and signed, we can begin work. In order to do so, we require the following:
- Site Survey Checklist completed, including:
- Site Location
- Utility Company
- AHJ
- Module selection
- Inverter selection
- Measurements and dimensions
- Applicable photos of site
At this early state, SepiSolar delivers:
- Dimensioned Site Layout
- Dimensioned System Layout
- Block Diagram/Single Line Diagram (SLD)
- Array Configuration
- System Specifications
- System Maximum Voltage Calculations
- AC System Summary
- 120% Rule Calculation (as applicable)
This first deliverable allows you to:
- Apply for Interconnection Application
- Validate the design by verifying the locations, quantities, and compatibilities of major equipment (aka dimensional analysis)
- Get approval from customer on equipment layout/locations on-site
In order to move to the next step, we require approval and/or any changes required to the preliminary deliverable. Rather than just addressing the requested revisions, we also proceed with the general electrical layout and 3-line diagram.
Our “30%” deliverable at this stage includes:
- Modifications from previous iteration
PLUS: - General electrical layout (conduit routes, equipment clearances)
- Preliminary 3-line diagram
This deliverable allows you to:
- Place purchase orders for major equipment
- Get lead times for major components and refine project CPM schedule
We’re now more than half-way to completion. To proceed, we require approval and/or any changes required to the 30% deliverable.
Our deliverable at this stage includes:
- Modifications from previous iteration
PLUS: - Electrical Layout with DC String Map (additional page)
- Wire and Conduit Schedule
- Conduit Fill & Temp Derate Calculations
- Conductor Calculations
This “60%” deliverable allows you to:
- Verify adequate minor materials (conduit, wire, etc) in the warehouse
- Develop a BOM (Bill of Materials)
We’re nearing completion but require approval and/or any changes required to the most recent deliverable.
Our “90%” deliverable includes:
- Modifications from previous iteration
PLUS THESE ADDITIONAL PAGES: - Title Page
- Notes Page
- Mounting and Racking Method
- Electrical Elevations
- Construction Details
- Block Diagram and Safety Placards
- Additional Notes and Signage Requirements
- Equipment Datasheets
This 10+ page deliverable allows you to:
- Prepare installation crew (verify means-and-methods and constructability)
To proceed, we require approval and/or any changes required to the 90% deliverable. At the completion of this stage, the project will be complete.
Our 15+ page deliverable at this stage includes:
- Modifications from previous iteration
PLUS: - Incorporation of design documents/sheets from other engineering disciplines (structural, geotech, architectural, etc.)
- Engineering Stamps
This final deliverable allows you to:
- Submit application to AHJ for Permitting
- Shift liability to separate company (us/SepiSolar)
