Free Solar Proposal & Savings Calculator Templates for Solar Companies

A solar sale usually needs three documents: a proposal that explains the system, a breakdown of the numbers the customer actually cares about (cost, payback period, 25-year savings), and a way to explain financing options without sounding like a script. Here's how to put all three together in minutes instead of hours.

The savings calculator

FLYNT Sheets includes a built-in Solar Savings Calculator template — real formulas, not a static PDF: system cost, federal tax credit, net cost after credit, annual energy savings, payback period, and 25-year total savings, all recalculating live as you change the inputs for a specific customer's system size and local rates.

The installation proposal

FLYNT Docs' AI generation includes a Solar-specific installation proposal prompt — describe the system (size, home details, financing approach) and get a formatted proposal draft to customize with the customer's actual numbers, rather than starting from a blank page for every deal.

The financing conversation

Financing is usually where a solar deal stalls — customers weighing cash purchase vs. loan vs. lease/PPA need it explained plainly. FLYNT Docs also includes a financing options explainer prompt that generates a plain-language breakdown of the available options, so every rep on your team explains financing consistently instead of improvising.

Putting it together

Run the savings calculator with the customer's real numbers, generate the proposal and financing explainer with those same numbers, and you have a complete, customer-ready packet — without three separate tools or a blank Word document. It's free to start with FLYNT, and both the calculator and the AI templates are available from the Sheets and Docs dashboards.
