Solar Site Surveys

Accurate, Reliable Site Surveys That Power Faster Design, Permits & Installations

Every successful solar project starts with one critical element: accurate site data.

At Solartro, our Solar Site Survey services capture every essential detail of your project—so your solar systems are designed correctly the first time, permitted smoothly, and installed without surprises.

Before a single panel is mounted or a permit is submitted, we deliver precise, code-compliant, field-verified data that eliminates guesswork, reduces redesigns, and accelerates approvals.

From residential rooftops to commercial facilities, EV infrastructure, and utility-scale projects, our comprehensive site surveys provide your design and engineering teams with everything they need—from roof measurements and electrical assessments to shading analysis and structural verification.

Accurate data in. Faster installs out.

We don’t just inspect sites —

we prepare projects for success.

Freequently Asked Questions

What does the Solar Proposal Design service include?

Complete proposal drawings (2D/3D), production & shading analysis, financial projections (payback, NPV, LCOE), equipment specifications, and client-ready presentation files (web link, PDF, slides).

How do you determine the right system size?

We analyze historical energy usage (if provided), roof constraints, shading analysis, and client goals (target offset %) to recommend optimal sizing. Can design from address-only or with detailed utility data.

How fast can I get a proposal?

Standard delivery: 12 hours. Priority: 4-6 hours. Express (high-volume partners): 30 minutes to 2 hours. 24/7 operations for global time zone support.

Is this service suitable for new installers?

Absolutely! Our professional proposals help new installers establish credibility from day one—clients can't tell if you've done 5 projects or 500 projects based on proposal quality.

How accurate are the savings estimates?

All projections are climate-specific, degradation-adjusted, and based on industry-validated modeling (NREL methodologies). We use real weather data, not national averages. Accuracy within ±5% of actual performance.

Can you support permits after the proposal stage?

Yes! Our proposal designs are fully compatible with our downstream Solar Site Surveys services. Seamless handoff from sales → permitting with zero data loss.

What if my client wants revisions after seeing the proposal?

Minor revisions (panel count adjustments, equipment swaps) are typically included. Major scope changes (different roof, system size changes) may require additional design time. High-volume partners get priority revision support.

How much does proposal design cost?

Pricing varies by project complexity, volume, and turnaround speed. Contact us for custom quotes—volume discounts available for installers with recurring needs.

How long does a site survey take?

On-site residential surveys: 45-90 minutes. Remote surveys: 4-12 hours for report delivery. Commercial/ground-mount: 2-4 hours depending on site size.

Do I need to be present during the survey?

Not required, but helpful. If the property is vacant or homeowner unavailable, we can coordinate access with your team or use a lockbox. Attic access may require homeowner presence.

What if the roof is too steep or unsafe to access?

We offer drone-assisted surveys for steep/high/unsafe roofs. Drones capture all necessary data without physical roof access.

Can you survey properties nationwide?

Yes! We have certified surveyors covering all 50 U.S. states, including Alaska and Hawaii.

How accurate are remote surveys compared to on-site?

Remote surveys using high-res aerial imagery are highly accurate for roof measurements (±2-3 inches). However, on-site surveys capture additional details like attic framing, electrical panel interior, and roof condition that remote methods cannot assess.

What if the survey reveals problems (bad roof, inadequate panel, shading issues)?

We document all findings honestly. This allows you to address issues proactively—whether that's recommending roof repairs, service panel upgrades, or adjusting the system design. It's far better to identify problems during survey than mid-installation.

Do you provide surveys for battery/generator installations?

Absolutely. Our surveys include battery location assessment, generator pad evaluation, electrical capacity analysis, and ATS (Automatic Transfer Switch) placement planning.

How is survey data delivered?

Via secure cloud link (Dropbox, Google Drive, or your preferred platform). Files are organized in folders (Photos, Report, Measurements) for easy navigation. Data is encrypted and privacy-protected.

Can I order a survey without ordering permit design?

Yes, surveys are available as standalone services. However, bundling survey + design saves time and money, with seamless data handoff between teams.

How much does a site survey cost?

Pricing varies based on project type, location, and survey method (on-site vs. remote). Contact us for a custom quote: [info@solartro.com] or [+1 307-429-3502].

Solartro provides professional solar permit design, solar engineering, CAD drawings, and PE-stamped plans for residential and commercial solar projects across all 50 U.S. states. Fast, accurate, and AHJ-compliant solutions.
