Frequently Asked Questions

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.

How do you maintain accuracy in solar designs?

We combine software tools with manual engineering checks.

We use industry-standard tools like Aurora and advanced CAD software for layout and calculations. However, we don’t rely only on software—our engineers manually verify system sizing, electrical diagrams, and structural considerations to ensure real-world accuracy.

Is your service suitable for small installers?

Yes, we support both small teams and large-scale companies.

Whether you’re handling a few installs per month or scaling rapidly, our services are flexible. Small installers benefit from reduced workload and faster turnaround, while larger companies use us to manage volume efficiently without expanding internal teams.

How do you communicate and share project updates?

Clear, consistent communication through your preferred channels.

 We adapt to your communication styleemail, shared drives, or project management tools. You receive regular updates on progress, delivery timelines, and any required inputs. Our goal is to keep everything transparent and easy to track.

Do you offer white-label solar design services?

Yes, we work as a backend partner under your brand.

Many clients prefer to present designs as their own. We support white-label services where all deliverables follow your branding, allowing you to maintain client relationships while we handle the technical work behind the scenes.

How do you support solar sales and proposal teams?

We create accurate designs that improve proposal quality and conversions.

Sales teams often need realistic layouts and system data to close deals. We provide accurate preliminary designs that help avoid overpromising and build trust with customers. This leads to better conversion rates and smoother project execution later.

Can you design battery storage and EV charging systems?

Yes, we handle integrated solar, storage, and EV charging designs.

Modern solar projects often include battery storage and EV charging. We design complete systems with proper electrical integration, load balancing, and layout planning to ensure everything works together efficiently and meets compliance standards.

How do you ensure data security and confidentiality?

We follow strict internal processes to protect all client data.

We understand that project data and client information are sensitive. Our team follows secure file handling, restricted access, and confidentiality practices to ensure your data remains protected at all times

What makes RS Solar CAD Group different from others?

We focus on real project outcomes speed, approvals, and scalability.

Many providers focus only on drawings. We focus on what happens after—approvals, timelines, and business growth. Our workflow is built to help you deliver faster, reduce rework, and scale operations without adding internal complexity.
