1. Introduction
As the U.S. solar market continues to grow, EPC firms are facing increasing pressure to deliver projects more quickly while adhering to rigid AHJ and NEC code regulations. High quality Solar CAD, ready-for-permit drawings, and design plans are essential for fast permits to get the job done.
But, conducting end-to-end Photovoltaic (PV) engineering in-house can be costly and time consuming — especially when teams are overstretched working on many projects.
This is the area when solar CAD drafting outsourcing becomes significantly advantageous.
Doing so will enable EPCs to spend less time, save money and speed up the process of solar project building. “Collaborating with a seasoned provider such as Southvine Energy can assist EPCs in saving valuable time, slashing operating costs and reducing overall solar project construction by weeks or months,” Simpson noted.
2. What Solar EPCs Need from Accurate Solar CAD Design
No matter where solar is installed — on homes, businesses or larger utility-scale projects — exacting engineering is key. High-quality Solar CAD drafting ensures:
- Correct equipment selection
- Accurate solar panel layout
- Correct wire size And Electrical schematic
- NEC and other local AHJ code compliance
- Seamless permit approvals
- Reduced installation errors
EPCs experience delays, redesign costs and permit denials without efficient PV system design.
3. Main Challenges of EPCs in In-house PV Engineering
Most EPCs struggle with:
High engineering and staffing costs
To keep trained men on drafting, engineering, model making and producing detail engineering drawings is expensive.
Fluctuating project volumes
Demand is seasonal — it’s not efficient to keep full-time staff year-round.
Increased permit complexity
AHJ A fire marshal’s requirements are different from state to state.
Tight installation deadlines
A slower turnaround also affects revenue and customer satisfaction.
These are the reasons why outsourcing Solar CAD services is a more intelligent choice.
4. What is Solar CAD Design Services Outsourcing?
Solar CAD outsourcing is when EPCs outsource to specialty engineering companies—such as Southvine Energy—to take care of all the PV engineering, drafting, modeling and desgins/ solar permit drawings.
This includes:
- CAD drafting
- PV system modeling
- Electrical layouts
- Structural layouts
- Bill of Materials (BOM) generation
- Code-compliant design documentation
With professional guidance, EPCs can grow quickly and concentrate on winning more solar projects.
5. Some of The Core Solar CAD Drafting Services EPCs Can Outsource
At Southvne Energy, we’re providing full CAD services for Solar:
✔ Solar Panel Layout

6. The Benefits of Outsourcing for Efficiency and Cost Savings
Lower Operational Costs
No hiring, training or maintaining large engineering teams.
Faster Turnaround Times
“Solar permit drawings ready in 24-48 hours provided by expert drafting teams.
Improved Accuracy & Compliance
PV design standards are reviewed on a daily basis by teams with which you outsource, so technical mistakes are minimised.
Scale on Demand
EPCs can process 5 projects or 100+projects with the same staffing load.
Reduced Rework
Brilliant solar design maximizes savings while minimizing remediation and site delays.
This provides immediate added value for EPCs operating in competitive markets to outsource.
7. Professional outsourced engineering services provide the EPC:
- AHJ-specific plan sets
- NEC-compliant design
- Accurate structural and electrical layouts
- Finished and washed clean drawings, for submittals
This leads to a dramatic decrease in the rejection of permits and speeds up project roll-out.
8.Expert PV System Design for Optimal Solar Design
