Leads arrive in your inbox

On the Pro plan, when a visitor submits a quote request the lead lands in your inbox — complete with their name, contact details, and the exact savings figures they saw.

Everything your website is missing

🎨

Fully branded — down to the pixel

Colours, fonts, company name, button styles, form borders, share button — all customisable from the dashboard. Choose from preset colour themes or build your own palette. Looks like you built it in-house.

✉️

Built-in lead capture form

On Pro, visitors submit their name, email, phone, and address directly inside the widget. Their calculator results are pre-filled on the form. The lead lands in your inbox the moment they hit send.

🔢

Your real numbers, not averages

Set your own install cost per kWp, battery price, grid rate, and export rate. Visitors see accurate payback periods based on what you actually charge — not industry averages that don't reflect your business.

Instant results, zero friction

No form before the results. Visitors drag the bill slider and see savings update in real time — annual saving, payback period, CO₂ offset, and a 25-year projected value. All instant.

📱

Mobile-first design

Looks perfect on every screen. Over 60% of solar research happens on mobile — your calculator is built for it from the ground up, not adapted as an afterthought.

🔒

Domain-locked to your site

Your widget only loads on your registered domain — nobody else can embed it. Every plan includes domain lock as standard, so your investment is protected from day one.

Your dashboard. Your widget. Your brand.

Every setting is controlled from a clean live-preview dashboard. Change a colour and watch the widget update instantly — no guesswork, no waiting, no developer needed.

Your best salesperson doesn't need a day off

Most solar websites ask visitors to fill in a form before they know if solar is even worth it for them. That's friction — and friction kills leads.

SolarCalc flips this. Visitors get their numbers instantly. By the time they click your quote button, they're already sold on the concept. You're just closing the deal.
