Solar savings calculator
Roof, bill and usage-based estimates on your website that turn visitors into qualified leads.
Solar installer software: savings calculators & quoting
Solar installers: show them the savings before the price. Leads that already want to buy.
Leads that never answer the phone, proposals built by hand, grid approvals lost in inboxes and installs scheduled in a spreadsheet. We build savings calculators, proposal tools and install systems for solar businesses that all talk to each other. Then we host them and look after them.
Looking for a solar savings calculator or quoting software that actually wins jobs?
Homeowners want to know one thing: what will this save me? Most solar websites make them fill in a form and wait for a call they'll probably dodge. Meanwhile your sales team is chasing tyre-kickers, building proposals across three different tools and trying to work out whether the latest battery rebate changes the numbers again.
Wollopit builds custom solar software around how your business actually sells and installs. A calculator that answers the savings question straight away and hands you a qualified lead with the roof, bill and usage details attached. Proposals that build themselves from that data. Install jobs that track approvals, STCs, photos and sign-off so nothing goes ahead until it's ready. We connect the tools you already use, replace the ones holding you back and look after the lot on our own servers.
01The problems
What we hear from solar installers
Does your solar business have these problems? Here's how we'd fix them.
Most solar businesses we talk to are brilliant on the roof and stretched thin in the office. Sales, design, paperwork and installs all run on different tools and somebody's memory.
- The problemLeads go coldGeneric enquiry forms bring in people who aren't ready, with no details about their home or their bill.How we fix itA savings calculator that captures roof, bill and usage details while showing a real estimate on the spot.
- The problemThree calls just to qualifyMissed calls and voicemails just to find out if they own the place and what they pay each quarter.How we fix itLeads scored on ownership, roof, bill and timing before anyone picks up the phone. Hot ones go straight to the top.
- The problemProposals take hoursEvery proposal is built by hand with panel layouts, pricing, finance and savings tables copied between tools.How we fix itProposals generated from the calculator data with your products, pricing and finance options in your branding.
- The problemBattery questions slow salesCustomers want solar only versus solar and battery, plus what the rebate does to the price.How we fix itSide-by-side scenarios showing payback with and without a battery, with rebates applied and kept current when the rules change.

- The problemInstall paperwork everywhereSTC forms, compliance certificates and install photos are scattered across inboxes and installers' phones.How we fix itEvery install's documents and photos tracked in one place, with a checklist that won't let a job close until it's complete.

03The systems
The big ones
Your whole solar business, on one system.
These are the systems solar businesses ask us about most. Each one works on its own and they get properly clever when they're joined up.
Savings calculator
Answer 'what will it save me?' before they even ask.
Homeowners put in their postcode, roof and power bill and get a real estimate on the spot. Behind the scenes you get a qualified lead with everything your designer needs, already sorted by how ready they are to buy.

- Roof direction, pitch and shading inputs
- Power bill upload or quick entry
- Solar only vs solar and battery
- Built on your panels and pricing
- Monthly finance repayments shown
- Lead scoring on ownership and timing
- Leads straight into your CRM or inbox
- Embeds on any website
Proposal builder
Proposals that build themselves from the lead.
The calculator data flows straight into a branded proposal with system design, pricing, finance and payback worked out. Send it as a live link, see when they open it and let them sign and pay the deposit without printing a thing.
- Your products, pricing and margins
- Panel layout and system specs
- Payback and savings tables
- Battery add-on options side by side
- Rebates applied automatically
- Finance options built in
- Open and view tracking

Approvals & paperwork
Every approval and photo tracked per install.
Each sold job moves through network approval, install, compliance, STCs and sign-off on one board. Missing paperwork gets flagged before it holds up payment. Nothing closes until the checklist is done.

- Chase reminders for overdue approvals
- STC forms and serial numbers
- Compliance certificates stored
- Required install photos checklist
- Documents attached to every job

- Approval check before booking
- Stock allocated per job
- Reorder alerts for panels and inverters
- Job packs and panel layouts on phones
- Serial number scanning

- Monitoring links for their inverter
- Fault and warranty requests
- Full install history on every ticket

07How we work
The process
Some people dip their toe in. We turn up in a rebreather.
We get properly below the surface of your solar business: the systems, the busy days and the jobs everyone hates. Then we fix the bits that matter most first.
- 01
Think
We sit with your sales team, designers and crews, then work out where leads, jobs and paperwork are getting stuck.
- 02
Archi-tech
We plan it before writing code: your products, pricing, rebates, approvals, crews, stock, hosting and cost.
- 03
Build
Real engineering, shown to you early and often. Usually the calculator or proposals first, so you get a win before the next quiet month.
- 04
Look after
We host it, maintain it and keep it current when rebates and tariffs change. When something breaks you call the people who built it.
08Questions
FAQ
Things solar installers ask us.
Something else on your mind? Ring 0423 011 252 and ask the people who'd build it.
Can the calculator use our own pricing and products?
Yes. It's built on your panels, inverters, batteries, pricing and finance partners, with estimates based on Australian sun and tariff data you're comfortable with.
How accurate are the savings estimates?
As accurate as the inputs allow. We set the assumptions with you and make it clear online that it's an estimate. Your proposal then firms it up with the proper design.
Can it handle battery rebates and changing rules?
Yes. Rebates and incentives are set up as settings, not hard-coded, so when the rules change we update them and every calculator estimate and proposal follows.
We already use OpenSolar or Pylon. Do we have to switch?
No. If your design tool is doing its job we build around it, with the calculator, pipeline, scheduling and portal connected to it. If something's holding you back we'll show you what replacing it would involve before anything changes.
Can it track STCs and grid approvals?
Yes. Every job shows its approval status, STC paperwork and required photos, with reminders to chase anything overdue and a checklist that stops a job closing until it's complete.
Will it work with ServiceM8 or simPRO?
Usually yes. We connect to the job management and accounting tools you already use so jobs, invoices and payments stay in sync.
How much does a solar system like this cost?
It depends on what you need, so we quote up front once we understand it. No surprise invoices, no lock-in and you own what we build.
How long does it take?
Smaller jobs like a savings calculator can be quick. Bigger systems are planned in stages so you get the first win early instead of waiting for everything at once.
Who looks after it once it's built?
We do. We host it on our own managed servers and keep it updated and secure. When you need something you ring the people who built it.
We already have systems. Can you upgrade them instead of starting again?
Usually, yes. Most solar installers we work with keep what's working and upgrade the rest in stages. We move your data across, connect the old and new while we switch and retire the old system only when the new one is proven.
