Precision-Engineered Solar Sales Proposals That Win More Deals — Faster

Every solar sale starts with one critical moment: the proposal presentation.

In those first few minutes, your client decides whether you're a professional they can trust—or just another salesperson with generic renderings and rough estimates.

At Solartro, we design sales-ready, engineering-accurate solar proposals that combine visual impact, technical precision, and financial clarity—helping installers close more deals with confidence.

From address-only designs to bankable 25-year financial models, our proposals are built to reduce objections, eliminate post-sale revisions, and accelerate approvals.

Whether you're a fast-growing installer closing 10 deals a month or a high-volume EPC managing hundreds of proposals weekly, our designs are engineered for one purpose: converting prospects into signed contracts.

What's Included in a Solartro Proposal Design Packages

Lightning-Fast Turnaround (Built For Sales Teams)

We understand sales doesn't wait. Leads lose interest fast. Competitors move quickly.

Our proposal turnaround times:

📌 Standard delivery: 12 hours (typical residential/small commercial)
📌 Priority delivery: 4-6 hours (for active sales campaigns)
📌 Express delivery: 30 minutes to 2 hours (for urgent, in-home presentations—available for high-volume partners)
📌 24/7 operations: Global team coverage ensures proposals delivered around the clock

For high-volume sales organizations, we deploy dedicated design teams that work in real-time with your sales reps—proposals delivered while you're still in the home closing the deal.

Platforn-Agnostic & Workflow-Friendly

We adapt to your tools, your process, your workflow—not the other way around.

Design Software We Work With:

✅ Aurora Solar (most popular—3D modeling, AI-driven design, sales mode)
✅ Helioscope (commercial-focused, fast turnaround, detailed shading)
✅ OpenSolar (free platform, global user base, integrated financing)
✅ PVsyst (engineering-grade simulations, utility-scale projects)
✅ Scanifly (drone-based designs, photogrammetry, 3D site capture)
✅ SolarGraf (CRM-integrated, mobile-friendly proposals)
✅ Custom internal tools (we can learn your proprietary workflows)

Frequently 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 Permit Design services. Seamless handoff from sales → permitting with zero data loss.

Do you work with battery storage and EV chargers?

Yes. We model battery backup systems (Tesla Powerwall, Enphase, LG Chem, etc.) with energy arbitrage analysis. EV charger load planning included for future-proofing.

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.
