Free Solar Calculator for Your Website: Embed It and Capture Leads (2026)
Most visitors to a solar installer's website leave without enquiring. A free solar calculator embedded on your site changes that: it lets a homeowner get an instant estimate of system size, cost and savings, and captures their details as a lead for you - 24/7.
This page lets you request a free solar calculator to add to your own website. Enter your details below and we will email you the embed code and setup instructions.
Why every solar installer should have a calculator on their website
More leads from traffic you already have
Most visitors to a solar website leave without enquiring. A calculator gives them a reason to engage and a reason to share their details.
Better-qualified leads
Because the visitor enters their bill, roof and location, every lead arrives with the context you need to follow up - not just a name and number.
Instant credibility
An interactive estimate makes your site feel modern and trustworthy, which matters when a homeowner is choosing between installers.
Works 24/7
The calculator captures enquiries while you are on site or asleep, and drops them straight into your pipeline.
How it works
- 1. Request it: Fill in the form above. We email you a short embed code and setup instructions.
- 2. Add it to your site: Paste one snippet into your website (works with WordPress, Wix, Webflow and plain HTML). It takes a few minutes.
- 3. Leads flow in: Every visitor who runs an estimate becomes a lead - captured with their inputs, ready for follow-up in your CRM.
What the calculator estimates
From a visitor's monthly electricity bill or roof size, the calculator estimates a suitable system size in kW, the indicative system cost, the PM Surya Ghar subsidy where eligible, the payback period and the long-term savings. To see the full breakdown, the visitor enters their name and contact - and that is your lead.
Turn calculator leads into customers
A calculator captures the enquiry; a CRM closes it. The leads from your website calculator can flow straight into the Fuzen Solar CRM, where every enquiry gets follow-up reminders, lead scoring, and a one-click solar quotation.
