Over the years, we have provided solar engineering services to a variety of clients, whether it’s a solar site survey, creating solar sales proposals, preparing solar permit designs, managing PE stamp requirements, or handling PTO & Interconnection. And over time, we’ve learned that choosing between in-house execution and outsourcing isn’t just about cost—it’s about quality, flexibility, and trust.
Let’s walk you through how we think about it—and how we’ve built a system that blends the best of both worlds.
Why In-House Matters in Solar Projects
There are certain things we believe are too important to delegate. For example, when we’re designing a solar permit package or reviewing structural details for a PE-stamped plan, we keep it in-house. That gives us tighter control, faster turnaround, and full alignment with code and AHJ’s requirements.
Why We Keep Key Solar Work In-House:
- Clear coordination between engineers and project managers.
- High understanding of local solar permitting rules and AHJ guidelines.
- Better control over quality, especially for permit-ready drawings and engineering stamps.
- Internal team moves faster with fewer back-and-forths.
But It’s Not Always Perfect:
- In-house teams can get overloaded during high-volume months.
- Scaling becomes a challenge without increasing overhead.
- Not every task needs full-time internal resources.
When and Why We Outsource
While managing multiple projects that need interconnection paperwork and basic drafting support or sudden surge in solar sales proposal requests it means we tap into our extended network. Outsourcing allows us to stay agile without compromising deadlines.
But here’s the thing—we don’t just send work out and forget about it. We’ve built strong systems to manage external vendors and review every submission thoroughly before it reaches the client.
Benefits of Smart Outsourcing:
- Scalable support for solar design, 3D modeling, or proposal drafting.
- Cost-effective for repetitive or overflow tasks.
- Access to experienced professionals in niche areas like utility interconnection or structural drafting.
- Helps maintain pace during permitting or PTO submission season.
But It Has Its Risks:
- Not all partners understand U.S. code compliance.
- Miscommunication can lead to delays or rework.
- Quality control is crucial—so we double check everything in-house.
How Vishtik Balances the Two
We’ve built our process with one thing in mind: deliver the most accurate, affordable, and timely solar engineering services possible.
So, here’s how we handle it:
- Core services like solar permit design, PE stamp drawings, and interconnection documents stay in-house.
- Support services like solar sales proposals, drafting assistance, or overflow PTO paperwork are carefully outsourced to vetted partners.
- Everything that leaves Vishtik’s desk is reviewed, optimized, and quality-checked by our engineering leads.
This hybrid approach lets us stay lean, responsive, and laser-focused on what matters most—our clients’ deadlines and satisfaction.
Final Thought
At the end of the day, whether it’s solar permitting, PE stamping, or full-stack solar engineering services, what matters is how well it’s managed—not just who’s doing it.
We’ve found that a thoughtful blend of in-house expertise and trusted outsourcing gives us the flexibility to scale, without compromising on precision or reliability. And that’s the reason solar companies across the U.S. trust us with their design and engineering needs.
