Manual Solar Estimates Cause Rework: Get It Right in the First Meeting with SolarDraft
A quick estimate on a calculator can win a meeting — and lose the project when the numbers turn out wrong.
This article is part of our series How to Close Solar Deals in the First Meeting. It covers one of the most common challenges Indian EPCs face — and how a 3D solar draft workflow with SolarDraft helps you solve it before the meeting ends.
The challenge
Many salespeople size systems with rules of thumb: bill amount divided by a number, roof area times another. It’s fast, but it ignores obstructions, orientation and losses.
When the final design differs, the customer feels misled.
Why it happens
- Rules of thumb ignore site specifics.
- Excel sheets aren’t connected to the roof.
- Losses are guessed or skipped.
- Different salespeople use different formulas.
What it costs your EPC
Re-quotes, changed capacities and revised prices damage trust and sometimes cancel orders.
How SolarDraft solves it in the first meeting
SolarDraft calculates losses while you design on a 3D model of the real roof, so the first-meeting quote is based on the same model the final design uses.
- Live loss calculation.
- Obstruction-aware one-click panel fill.
- Energy report from the 3D model.
- Add your own panels for accurate specs.
First-meeting playbook: 5 steps
- Stop quoting from formulas.
- Build the solar draft on the real roof.
- Select the exact panel model you’ll install.
- Let SolarDraft calculate losses and generation.
- Quote from the design, not from memory.
If the quote isn’t based on a design, it’s a guess. Customers can tell.
Solar draft vs traditional first meeting
| Traditional first meeting | With a SolarDraft 3D solar draft | |
|---|---|---|
| What the customer sees | Brochure & price list | Their own roof in 3D |
| Energy estimate | Rule of thumb | Energy report with losses |
| Proposal | Sent 2–3 days later | Built in the meeting |
| Absent decision makers | Hear it second-hand | Open the 3D link |
| Typical outcome | “Let me think about it” | Decision today |
