Proposal & Shading Analysis

Proposals That Close. Numbers That Hold Up.

A solar proposal is only as good as the data behind it. We build custom solar proposals backed by detailed shading analysis and accurate production estimates — so your sales team can close with confidence, and your customers get numbers that hold up after installation.

Our Work Process

From Site Data to Sales-Ready Proposal

01

Site & Shading Analysis

We assess site-specific shading factors — trees, obstructions, roof orientation, and tilt — to model realistic energy production, not best-case guesses.

02

System Sizing & Production Modeling

Using verified site data, we calculate optimal system size and generate accurate production and performance.

03

Proposal Design & Delivery

We turn the analysis into a clean, sales-ready proposal — with production estimates, savings projections, and ROI laid out clearly for your customer.

FAQs

It measures how nearby trees, structures, or roof geometry affect sunlight exposure — directly impacting real energy production. Skipping this step often leads to overpromised system performance.

Our estimates are built on verified site data and shading analysis, so production numbers closely reflect real-world performance rather than best-case assumptions.

Yes — proposals can be formatted to match your company's branding and sales presentation style.
