Who We Are

Our Company Overview

At RS Solar CAD Group, we are committed to advancing renewable energy through precise and reliable solar design services. With a team of skilled engineers and CAD professionals, we deliver high-quality, permit-ready solar plan sets with fast turnaround times and strong approval success rates.

We partner with solar installers, EPC companies & vendors, financing partners, manufacturers & suppliers, and mounting & racking companies across the United States and Canada to deliver permit-ready solar design solutions with speed and accuracy.

Our Expertise

Services Suite

RS Solar CAD Group provides an integrated outsourcing model supporting solar installers, EPCs, and engineering firms across the U.S. and Canada. We act as a captive offshore extension of your in-house team, ensuring high-quality, scalable execution aligned with your standards.

Solar Design Services

We handle the full design side of your solar projects – from proposal layouts to permit plan sets. The designs are made the way installers actually need them, so approvals don’t get stuck and your team doesn’t waste time fixing drawings later.

Engineering Stamping Services

We don’t redesign your work – we check it, correct it where needed, and get it stamped. This helps you avoid rejection due to small errors and keeps your project moving without repeated comments from authorities.

EV Charging Station Plans

We create EV charging plans that are easy to approve and easy to build. Load calculations, layouts, and documentation are all prepared in a way that your team can directly use on-site without confusion.

Workforce & Staffing

Instead of hiring and training new people, you can work with our team as your backend support. We handle design tasks, updates, and even basic follow-ups so your internal team can focus on execution and closing projects.

Solar Installation Services (India)

For India-based projects, we don’t stop at design – we help get the system installed properly. From planning to final setup, the focus is on completing the work correctly and making sure everything runs as expected.

FAQ

Frequently Asked Questions

We combine engineering precision with real-world installation experience to deliver designs that work.

How do you ensure first-time approval for solar permit plans?

We design based on exact AHJ requirements and perform strict QA checks before delivery.

Every jurisdiction has different expectations, and most rejections happen due to small compliance gaps. Our team follows AHJ-specific guidelines, NEC codes, and utility requirements from the beginning. Before delivery, each plan goes through an internal quality check where we verify layouts, labels, calculations, and documentation. This reduces back-and-forth and helps achieve a consistently high first-time approval rate.

What information do you need to start a solar design project?

Basic project details like site info, system size, and equipment are enough to begin.

To start quickly, we typically need the site address, utility bill, system size (or target offset), and any preferred equipment. If you have site photos, roof dimensions, or drone images, that helps improve accuracy. Even if some details are missing, our team can guide you step-by-step and still initiate the design process without delays.

Can you handle bulk or daily project volumes?

Yes, we are built to support high-volume solar businesses.

Our team structure is designed for scalability. Whether you’re handling a few projects per week or large daily volumes, we can manage your workload without affecting turnaround time. Many EPCs and installers use us as their extended design team, allowing them to grow without hiring and training in-house designers.

How do you manage urgent or same-day design requests?

We have a fast-track workflow for urgent and priority projects.

We understand that some projects are time-sensitive—especially when permits or installations are scheduled. For urgent cases, we assign priority resources and follow an accelerated workflow. Depending on project complexity, we can deliver same-day or overnight designs, helping you meet tight deadlines without compromising quality.

What happens if a permit gets rejected?

We quickly revise designs based on AHJ feedback at no hassle.

While rejections are rare, they can happen due to changing AHJ expectations. In such cases, we review the comments, update the drawings accordingly, and resubmit quickly. Our goal is to minimize delays and keep your project moving. We stay aligned with AHJ feedback to avoid repeated issues in future submissions.

Do you customize designs based on our company standards?

Yes, we align with your design format, branding, and workflow.

Every company has its own way of working—title blocks, equipment preferences, design styles, and documentation formats. We adapt to your internal standards so that every plan set looks consistent with your brand. This is especially useful for EPCs and installers managing multiple teams or clients.

How do you handle different AHJ requirements across regions?

We follow region-specific codes and maintain updated compliance knowledge.

AHJ requirements vary widely across states and cities. Our team keeps track of these differences and applies the correct standards for each project. We continuously update our internal processes based on new codes, ensuring that your designs remain compliant no matter where the project is located.

Can you work with our preferred equipment and system configurations?

Yes, we design using your selected modules, inverters, and systems.

We don’t force standard configurations. Whether you use specific brands or unique system setups, we design accordingly. Our team ensures compatibility between components, proper system sizing, and compliance with manufacturer and electrical guidelines.
