Why every solar installer needs a calculator widget on their website
Most solar installer websites have a generic "Contact Us" form. The problem? A homeowner who has no idea what solar will cost them is unlikely to fill it out. A solar calculator widget changes that equation completely — the visitor gets an instant, personalized estimate, and by the time they see their Rs 14 lakh savings figure, they are far more willing to share their contact details.
Instant lead qualification
Every lead arrives with bill amount, recommended system size, subsidy amount, and expected savings already calculated. Your sales reps skip discovery calls and go straight to quoting.
Capture high-intent visitors
A homeowner who enters their electricity bill and sees a Rs 14 lakh savings estimate is far more likely to convert than a visitor who hits a cold "Contact Us" form.
CRM-connected, not siloed
Leads flow directly into your SolarFlow CRM pipeline — no CSV exports, no manual entry, no missed contacts. Every widget submission is a CRM record tagged with source "Website Solar Calculator."
Zero technical skill required
Copy one block of code, paste it into any website builder — WordPress, Wix, Webflow, Squarespace, Shopify, or raw HTML. The embed code auto-includes your CRM credentials. No API keys to configure.
What the visitor sees: how the solar savings calculator works
The solar calculator widget presents a clean, branded interface on your website. The visitor enters their monthly electricity bill (with a slider for quick adjustment from Rs 500 to Rs 50,000) and optionally their available roof area. One tap on "Calculate Savings" reveals the full estimate.
The results grid: 6 key metrics at a glance
After calculating, the visitor instantly sees six key metrics in a visual card grid. Here is what a homeowner with a Rs 3,000 monthly electricity bill would see:
Conversion design: The lead capture form appears only after the visitor sees their personalized savings estimate. This anchoring technique — showing the Rs 14 lakh benefit before asking for contact details — dramatically increases form completion rates compared to a cold "Contact Us" page.
Lead capture form: "Get Your Free Quote"
Immediately after the results, a "Get Your Free Quote" form appears with just 4 fields — name, phone, email, and city. The subheading reassures the visitor: "A solar expert will contact you within 24 hours." The form auto-formats Indian phone numbers to +91 and submits directly to your SolarFlow CRM.
What you see in your CRM: leads with full context
When a visitor uses the solar calculator on your website and submits their details, the lead appears instantly in your SolarFlow CRM Leads page — in a Kanban pipeline view. Each widget lead arrives with:
- Status: "New" (ready for first contact)
- Source: "Website Solar Calculator" (filterable)
- Contact details: Name, phone (+91 formatted), email, city
- Calculator data: Bill amount, system size (kW), total cost, subsidy amount, net investment, monthly savings, annual savings, 25-year savings, payback period
Your sales reps can immediately see what the visitor's bill is, what system was recommended, what the subsidy covers, and start the conversation with full context. No discovery call needed — the calculator already did that work.

Supported website platforms:
The widget uses Shadow DOM for complete style isolation — it will not break your website's CSS, and your website will not break the calculator's design. It works on any platform that accepts custom HTML.
Solar calculator specifications
The calculator uses current India-market parameters for accurate estimates. These are the default values — they can be customized to match your region's tariffs and costs:
| Parameter | Default Value |
|---|---|
| Electricity tariff | Rs 8/unit (India average) |
| Generation capacity | 4 kWh per kW per day |
| Installation cost | Rs 60,000 per kW |
| Roof area per kW | 100 sq ft |
| Panel wattage | 400W |
| Panel degradation | 0.5% per year |
| Electricity escalation | 5% per year |
| Maintenance cost | Rs 2,000 per year |
PM Surya Ghar subsidy rates (built into the calculator)
The solar calculator has the current PM Surya Ghar government subsidy rates pre-configured. This is the single biggest conversion hook — homeowners searching for "pm surya ghar calculator" or "solar subsidy calculator india" want to know exactly how much government money they can claim. Your calculator tells them instantly.
| System Size | Subsidy Rate | Example |
|---|---|---|
| Up to 2 kW | Rs 30,000 per kW | 2 kW system = Rs 60,000 subsidy |
| 2 to 3 kW | Rs 18,000 per kW (incremental) | 3 kW system = Rs 78,000 subsidy |
| Above 3 kW | Capped at Rs 78,000 | 5 kW system = Rs 78,000 subsidy |
Marketing angle: The subsidy is the hook. "Rs 78,000 government subsidy — are you eligible?" drives homeowners to use the calculator. Once they see their personalized estimate, the lead form appears. That is how a solar calculator widget on your website generates 3-5x more leads than a generic contact form.
Customizable to match your brand
The solar calculator widget is fully customizable. You can adjust:
- Calculations: Change tariff rates, installation costs, generation assumptions, and subsidy parameters to match your region
- UI design: Customize colors, fonts, and layout to match your website branding
- Branding: Add your company logo and personalize the messaging
- Lead form fields: Configure which fields the lead capture form collects
Everything runs inside a Shadow DOM container, so the widget's styles never interfere with your host website — and your website's CSS never breaks the calculator.
Solar lead generation: why a calculator beats paid leads
Most solar installers spend Rs 500-2,000 per lead buying from aggregator platforms. The leads are shared with 3-5 other installers, and conversion rates hover around 2-5%. A solar calculator for your website flips this model:
| Factor | Aggregator Leads | Calculator Widget Leads |
|---|---|---|
| Cost per lead | Rs 500-2,000 | Rs 0 (included in SolarFlow CRM) |
| Exclusivity | Shared with 3-5 installers | 100% exclusive — your website, your lead |
| Lead quality | Name + phone only | Bill amount, system size, subsidy, savings, payback — full context |
| Conversion rate | 2-5% | 8-15% (anchored by savings estimate) |
| CRM integration | CSV export, manual entry | Auto-synced to SolarFlow CRM pipeline |
| Brand building | None — aggregator owns the relationship | Calculator on YOUR site builds YOUR brand |
The math is straightforward: if your website gets 1,000 visitors a month and 5% use the calculator (50 people), and 30% of those submit the form (15 leads), you are generating 15 exclusive, context-rich leads per month at zero incremental cost. Compare that to buying 15 shared leads at Rs 1,000 each — Rs 15,000/month for lower-quality contacts.

How do I add a solar calculator to my website?
Sign in to your SolarFlow CRM account, go to the Solar Calculator page in the sidebar, click "Copy Code", and paste the embed snippet into any page on your website using your platform's HTML embed feature. The widget works on WordPress, Wix, Webflow, Squarespace, Shopify, and any site that accepts custom HTML. The entire setup takes under 3 minutes.
Is the solar calculator widget really free?
Yes. The solar calculator widget is included free with every SolarFlow CRM account — there are no additional charges for embedding it on your website. Start a free trial to get your embed code immediately.
What does the solar calculator estimate?
The calculator shows the visitor six key metrics: recommended system size (kW and number of panels), total installation cost, PM Surya Ghar government subsidy amount, net investment after subsidy, monthly electricity savings, and payback period. It also displays 25-year total savings, CO2 offset, and annual generation figures.
Does it capture leads automatically?
Yes. After the visitor sees their solar estimate, a "Get Your Free Quote" form appears asking for name, phone, email, and city. When they submit, the lead — along with all calculated figures — lands directly in your SolarFlow CRM as a new lead record tagged "Website Solar Calculator."
Does the calculator include PM Surya Ghar subsidy rates?
Yes. The current PM Surya Ghar subsidy slabs are built in: Rs 30,000/kW for the first 2 kW, Rs 18,000/kW for the 3rd kW (incremental), and a cap of Rs 78,000 for systems above 3 kW. The calculator automatically applies the correct subsidy based on the recommended system size.
Can I customize the calculator's appearance and calculations?
Yes. The widget supports full customization — you can adjust tariff rates, installation costs, generation assumptions, and subsidy parameters to match your region. You can also customize the UI design, colors, and branding to match your website. Everything runs in a Shadow DOM container for complete style isolation.
Will the widget break my website's design?
No. The solar calculator uses Shadow DOM for complete style isolation. This means the widget's CSS never interferes with your host website's styles, and your website's CSS never affects the calculator. It is a fully self-contained component.
How is this different from buying solar leads from aggregators?
Aggregator leads cost Rs 500-2,000 each and are shared with 3-5 installers. Calculator widget leads are free (included in SolarFlow CRM), 100% exclusive to you, and arrive with full context — bill amount, system size, subsidy, savings, and payback period. Your sales team skips discovery and goes straight to quoting.
What is a solar ROI calculator?
A solar ROI calculator helps homeowners estimate their return on investment from installing rooftop solar panels. It factors in electricity bills, system size, installation cost, government subsidies (like PM Surya Ghar), panel degradation, electricity price escalation, and maintenance costs to show the payback period and long-term savings. The SolarFlow calculator widget does all of this and also captures the visitor's contact details as a lead in your CRM.
Can I use this solar calculator for commercial or industrial projects?
The default configuration targets residential rooftop solar under PM Surya Ghar. For commercial/industrial (C&I) projects, you can customize the calculator parameters — tariff rates, system sizing rules, and subsidy parameters — to match C&I project economics. Contact SolarFlow support for guidance on configuring C&I calculators.
