Pre-Sales Tools — the six calculators that live before the quote
Pre-Sales Tools are six calculators for the conversations that happen before you send a customer a real quote — before they’ve committed, before you’ve measured anything, before you know what brands you’ll install.
Why they exist
Section titled “Why they exist”A first conversation usually starts with a specific question: will my roof work? how long until it pays back? what’ll my bill look like? how much does this cost? how many panels fit? is there any government help?
Each question has its own tool, usable in under a minute with whatever the customer already has to hand — no Quote Generator, no ordered equipment, no site visit required.
The six tools
Section titled “The six tools”| Customer’s question | Tool | What it takes | What it returns |
|---|---|---|---|
| Will my roof work? | solar-potential | Address (any format worldwide) | Usable area, annual generation, monthly shape, suggested kWp |
| How long to pay back? | roi-calculator | Monthly bill + roof orientation + postcode | Payback years, annual savings, 20-year total, recommended kWp |
| What’ll the bill look like? | bill-savings | Monthly bill + kWp + live tariff + export credit | Savings/month, savings/year, kWh generated, self-sufficiency % |
| How much does the install cost? | cost-estimator | kWp + component tier | Line-item cost table by category, total incl. Greek 6% VAT |
| How do panels fit on the roof? | panel-layout | Panel size + rows per section | Panel count, kWp, m² covered, generation estimate |
| What incentives apply? | subsidy-checker | (nothing — country-scoped, currently Greek only) | Current programme catalogue with status, amounts, eligibility |
When to use which
Section titled “When to use which”Pre-sales conversations rarely follow one tool in isolation. A useful order:
- solar-potential first — an address gets you a same-conversation feel for whether the roof is worth pursuing.
- bill-savings or roi-calculator next — Bill Savings for a bill-shaped question, ROI Calculator for a payback-shaped one. Same underlying assumptions, consistent answers.
- cost-estimator when price comes up — a defensible ballpark by component category before Quote Generator.
- panel-layout when physical fit is the sticking point — how many panels, what orientation, where a chimney gets in the way.
- subsidy-checker whenever incentives come up.
Any of them can start the conversation; none of them can end it.
What Pre-Sales Tools are not
Section titled “What Pre-Sales Tools are not”They’re not:
- A customer-ready quote. For that, use Quote Generator v2 — see how-to-create-a-quote, which handles real brand names, quantities, VAT on actual line items, GPO offers, and a sendable PDF.
- A site survey substitute. The tools don’t know pitch, shading over the day, structural constraints, or hidden roof damage — only a visit catches those.
- A binding commitment. The numbers are ballparks; every tool bakes in Greek defaults for irradiance, tariffs, and regulatory rates, and a real quote adjusts for the actual project.
Use them to get the customer to yes, let’s talk properly — not to replace the properly-talking that comes next.
