Solar System CAD Drawing: Professional AutoCAD Plans
Lion Solar provide solar drafting and AutoCAD layout documentation for EPCs managing projects across multiple regulatory environments. Our drafting workflows adapt to local grid codes and engineering standards while ensuring build-ready DWG outputs.
Accurate planning is the foundation of every successful PV installation. Whether you are an EPC or an installer, having a detailed solar panel cad drawing is essential to avoid costly on-site errors and ensure quick permit approvals. At Lion Solar, we specialize in creating high-precision technical layouts that align perfectly with your project needs.
Fire protection, electrical plans, and cable schematics, along with mounting layouts, can all be included in our AutoCAD plans, which offer permit-submittable drawings to ensure seamless approvals and smooth on-site installations. If you would like to see how our AutoCAD plans look in practice and how they support permits and installation, you can start with a free test project no commitment required.
Without detailed AutoCAD plans, projects risk:
- Delays due to missing detail
- Redesign costs in the field
- Authority review rejections
- Miscommunication between crews
We produce permit-submittable DWG/DXF deliverables that streamline approvals and construction.

Frequently Asked Questions
For a complete solar PV system design, we require the site layout or architectural drawings, the planned PV system capacity, preferred module and inverter specifications, chosen mounting method, and utility interconnection details.
Our electrical plans typically include one-line diagrams (SLD), string layout, cable sizing, voltage drop calculations, grounding and lightning protection plans, and switchgear/safety device specifications.
Yes. We adapt our designs to meet the specific electrical codes and utility interconnection requirements of your region, including TEDAŞ, IEC, NEC, or other applicable standards.
Yes. We include short circuit analysis, load flow analysis, fault analysis, and protective device coordination, along with grid connection checks, to ensure system safety and compliance.
Yes. We can design electrical schematics that integrate solar battery storage, hybrid inverters, and backup systems with the PV installation, including options for an off grid solar system.
We follow international IEC standards and project-specific requirements, considering current carrying capacity, voltage drop limits, and short circuit withstand capacity.
Yes. Our plans cover both AC and DC electrical design, from PV strings to grid interconnection, including all protection devices.
We include complete earthing and protective surge and lightning protection layouts, ensuring compliance with safety standards and minimizing the risk of damage from surges.
Our AutoCAD workflow is built around rigorous engineering standards, including the NEC 705.12 (120% Rule) for busbar loading. We don’t just “draw panels”; we design systems that are electrically sound and ready for AHJ (Authority Having Jurisdiction) approval.
Code Compliance Check: Nervous about permitting? Let us review your layout and provide a Free Test Project to ensure it meets all regulatory standards.
Delivery time depends on project size and complexity. Most residential or small commercial systems can be completed within 4-6 business days, while larger utility-scale projects may require more time.
We deliver electrical plans in AutoCAD (DWG) and PDF formats, along with any supporting calculation sheets, so they are ready for submission to authorities or installers.
You will need to provide the address (including ZIP code), annual electrical usage, desired system size (or panel count), and details on materials (panel, inverter, battery). Optional information includes a Google Maps link, name, roof angle, roof dimensions, total system cost, electrical cost (€/kWh), and pictures of the house/business.
Yes. While simulation tools like PV*sol or Helioscope are vital for energy estimates, AutoCAD remains the undisputed standard for technical precision, permitting, and construction-ready documents. It bridges the gap between a “simulation” and a “buildable project.”

Pricing for electrical plans depends on the complexity of the work, we charge per hour, depending on the work we will provide our one time offer.
