Address lookup and roof analysis
Address autocomplete plus roof segments and sun hours from Google's Solar API, with PVWatts estimates where imagery is missing.
The Problem
Visitors Want a Savings Number, and Your Site Offers a Form
It happens the moment a homeowner wonders what solar would save. Most installer sites answer with a contact form, so the visitor leaves to find a number somewhere else.
No number
Visitors want savings figures, but your form only asks for contact details.
No number
The calculator shows a system size and savings range before the full estimate.
Bad leads
Renters and shaded roofs fill your pipeline with dead leads.
Bad leads
Ownership, roof, and shade questions score each lead before it reaches a rep.
Guessed math
Generic widgets use national averages instead of your prices.
Guessed math
Estimates use your price per watt, local utility rates, and the roof's sun hours.
Retyped leads
Reps copy each web lead into the CRM by hand.
Retyped leads
Each lead lands in your CRM with address, bill, and estimate attached.
A homeowner lands on your site after seeing a neighbor's new panels. They want one number: what solar would save on their bill. Your site offers a contact form that asks for a name and a phone number, so they leave and try a lead marketplace instead. The few who fill it in turn out to be renters or homes under heavy shade. Your reps spend the week calling people who weren't going to buy.
We start with the questions homeowners ask: how many panels, what size system, and how much it saves. Then we build a calculator that answers them from the visitor's address and bill, using roof data where it exists and your own price per watt. The full estimate opens after a short form about ownership and shade. Your reps get qualified leads with the numbers attached, not cold names.
Roof data from the address
Google's Solar API reads roof segments and sun hours wherever its imagery covers the home.
Your prices, not averages
Your price per watt and the local utility rate drive every estimate the visitor sees.
Leads that arrive qualified
Ownership, roof age, and shade answers score each lead before your reps call.
Our Solar Calculator for Website Process
From Pricing Review to a Live Calculator in Five Clear Steps
You approve every input and output before we build, then check the calculator's estimates against real proposals your designers made. Nothing goes live until your sales lead signs off.
We review your current lead form, your price per watt, and the utilities you serve, then agree on what the calculator shows before the form. You get a written scope that lists every input and output.
What's Included
What You Get With a Custom Solar Calculator Widget
Your calculator covers address lookup, roof data, savings math, battery and financing options, the lead form, and the hand-off to your CRM. It runs on your site and your accounts.

DeveloperLook vs Free Widgets vs Calculator Subscriptions
A free widget suits one service area at average prices, and a subscription app works for teams that want settings, not code. Here is where each one fits.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built websites, lead forms, and booking flows for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Solar Installers Trust Us With Their Calculator
A homeowner's first number shapes the whole sale. These habits keep your estimates honest, your leads qualified, and the numbers online close to what your reps quote.
Estimates labeled as estimates
Every result says what it's based on and that a site visit sets the final design. Homeowners trust a range they understand more than a precise number that changes later.
Checked against real proposals
We compare the calculator's output with proposals your designers made for real homes. Your online ranges then match what your reps quote at the kitchen table.
Honest about roof coverage
Google's Solar API doesn't cover every home, and we show you where it falls short. Those addresses get a PVWatts estimate instead of an error screen.
No incentive figures without a source
Tax credits and rebates change, so the calculator shows only incentive amounts your team enters and updates. It won't quote a program the homeowner may not qualify for.
Honest about free widgets
If a free widget already covers your area and pricing, we'll tell you before we quote. Custom work earns its cost when you need your prices, your brand, and your CRM.
Your leads and your code
The code, the API keys, and every lead are yours from day one. Your calculator keeps working if you change agencies, CRMs, or proposal software.

Good fit
Residential solar installers
Your website gets traffic from local ads, and you want a solar calculator for your website that turns visitors into booked site assessments.
Installers selling batteries with solar
You sell storage with most systems, and you want the calculator to show a battery option next to the panels.
Solar companies in several states
You serve more than one state or utility, and each market needs its own price per watt and rate assumptions.
Teams replacing a generic widget
You embedded a generic solar calculator widget, and it shows national averages, someone else's branding, and leads you can't send to your CRM.
Agencies building solar sites
Your agency designs websites for solar installers, and your clients keep asking for a calculator you can add under your brand.
Not a fit
Full solar website
You need a whole new website with service pages, galleries, and financing pages. Our Solar Company Website Design page covers the full site.
Design and proposal software
You need roof designs and signed proposals tied to your CRM. Our Aurora Solar Integrations page covers that sales workflow.
One area, average prices
You serve one area at standard prices and don't need a CRM hand-off. A free widget may be enough, and we'd rather you start there.
Budget under $900
Your budget is under $900 for the calculator. A free embeddable widget is a reasonable start until your lead volume justifies a custom build.

A custom solar calculator from DeveloperLook starts at $900 for a savings estimator with your prices, a lead form, and email alerts. A roof-aware calculator with Google's Solar API, a battery option, and CRM hand-off starts at $2,300. A proposal-ready version with financing comparisons and market pricing starts at $4,400. You get a fixed quote after a free review.
Most solar calculators take 3 to 8 weeks from review to launch. A savings estimator with a lead form takes about 3 weeks. Adding roof analysis and a CRM hand-off runs 4 to 6 weeks, and financing comparisons with market pricing take up to 8. The accuracy check against your real proposals takes 3 to 5 days of that.
Sometimes, yes. A free solar calculator for website embeds works when you serve one area at average prices and only need an email lead. It falls short when you need your own price per watt, roof data, qualifying questions, or leads sent straight into your CRM. Many installers start free and switch later.
It divides the home's yearly use by what one panel would produce on that roof. Yearly use comes from the visitor's bill, and production comes from Google's Solar API sun data or a PVWatts estimate. The result rounds to whole panels that fit the usable roof area, with a note that a site visit sets the final design.
It uses Google's Solar API wherever aerial imagery covers the address, which returns roof segments, pitch, direction, and sun hours. Where coverage is missing, it falls back to a PVWatts estimate from the location and a standard roof setup. Both services need API keys in your name, and Google bills its API by usage.
It multiplies yearly production by the visitor's utility rate to get bill savings, then compares that with your system price. Payback is the price divided by yearly savings, shown as a range. Battery and financing options change the result only if your company offers them and enters the terms.
Yes, but only the amounts your team enters and keeps current. Incentive programs change and depend on each homeowner's situation, so we don't build in figures from outside sources. The result screen labels incentives clearly and tells the homeowner that eligibility gets confirmed during the proposal.
Yes. It ships as one embed that works on WordPress, Webflow, Squarespace, Wix, or a custom site, and it loads only on the pages where you place it. It keeps your fonts and colors, works on phones, and sends conversion events to GA4, so you can see which ads bring leads.
Each lead goes to your inbox and your CRM with the address, bill, roof answers, and estimate attached. We connect HubSpot or Salesforce directly, and other CRMs through their API or Zapier. On the top plan, a qualified lead can also start an Aurora Solar project, where your Aurora plan includes API access.
You do. The code, API keys, and every lead are yours from day one, and the calculator runs on accounts in your name. You get 30 days of post-launch support for fixes and small changes. Prices and rates live in a settings file, and we show your team how to update them.
