Site survey reports and proposal collateral for solar installers

Fibvo editorial · 21 February 2025 · 4 min read

Solar buyers frequently compare two or three quotes with different system sizes, panel types and payback claims. A proposal that hides its assumptions behind a single bottom-line payback number is hard to compare fairly, and a buyer who cannot compare fairly often distrusts the biggest number instead of the most honest one.

What a clear proposal shows

• System size, panel specification and expected generation, stated plainly.
• The tariff rate and generation assumptions used to calculate payback, shown explicitly.
• Total cost after subsidy, with the subsidy amount itself broken out separately.
• Warranty terms for panels, inverter and installation workmanship, listed separately since they often differ.

Site survey report design

A report showing actual roof measurements, shading analysis and orientation, with photos from the survey, gives a buyer confidence the proposal is based on their specific home, not a generic template applied to every enquiry.

A buyer who can see your assumptions trusts your number more than one who only sees your conclusion.

Formatting for sharing

Since the decision is often shared with family, a clean, easy-to-forward PDF summary — separate from the full technical report — helps the buyer's household actually discuss the numbers together.
