Example 24 · Grow · Solar and battery installer
Lay the panels on your roof, and see when they would pay for themselves.
Everyone thinking about solar asks how long until it pays for itself, and most answers are a sales pitch. This one shows its working: a roof of their own, every assumption listed, a best case and a worst case, and a chart of the years.
Illustrative scenarioWorking demo
What the customer sees
Before
Every enquiry started with a phone call to work out the roof and the bills. People with a north facing roof or a tiny bill took the same survey as people who would clearly benefit, and nobody trusted a single payback figure.
Built in a day
A tiled roof of 24 places you lay panels on by tap, drag or keyboard, a compass that turns the roof to one of eight ways, a payback range worked out from listed assumptions, a chart of the first 25 years drawn at its real width, a roof survey request, a personal PDF of the roof and the payback, and the results by email. Built with AI in under a day.
What it's for
Give a homeowner an honest range before the survey, book surveys with people whose roof and bills suit solar, and hand the surveyor the roof, the facing and the battery question before they arrive.
The important bit
Built in a day. Going live takes more.
Before real customers relied on this, it would need:
- The installer's real prices, the tariffs they use and the yield figures they trust, for the areas they cover
- A surveyor's check of the ranges against real installations before anyone relies on them
- A diary the survey request can really book into
- Leads sent into the CRM with the system size, facing and payback as bands, never the figures or the panels
- Checks against the rules for grants, certification and the price of exported electricity
- A privacy notice and consent for storing people's contact details
On the day, we'll tell you honestly which of these your idea needs, and what they'd take.
